// requests, see [Searching the web for
// news](https://docs.microsoft.com/en-us/azure/cognitive-services/bing-news-search/search-the-web).

// Category sends the category request.
// Parameters:
// acceptLanguage - a comma-delimited list of one or more languages to use for user interface strings. The list
// is in decreasing order of preference. For additional information, including expected format, see
// [RFC2616](http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html). This header and the
// [setLang](https://docs.microsoft.com/en-us/rest/api/cognitiveservices/bing-news-api-v7-reference#setlang)
// query parameter are mutually exclusive; do not specify both. If you set this header, you must also specify
// the [cc](https://docs.microsoft.com/en-us/rest/api/cognitiveservices/bing-news-api-v7-reference#cc) query
// parameter. To determine the market to return results for, Bing uses the first supported language it finds
// from the list and combines it with the cc parameter value. If the list does not include a supported
// language, Bing finds the closest language and market that supports the request or it uses an aggregated or
// default market for the results. To determine the market that Bing used, see the BingAPIs-Market header. Use
// this header and the cc query parameter only if you specify multiple languages. Otherwise, use the
// [mkt](https://docs.microsoft.com/en-us/rest/api/cognitiveservices/bing-news-api-v7-reference#mkt) and
// [setLang](https://docs.microsoft.com/en-us/rest/api/cognitiveservices/bing-news-api-v7-reference#setlang)
// query parameters. A user interface string is a string that's used as a label in a user interface. There are
// few user interface strings in the JSON response objects. Any links to Bing.com properties in the response
// objects apply the specified language.
// userAgent - the user agent originating the request. Bing uses the user agent to provide mobile users with an
// optimized experience. Although optional, you are encouraged to always specify this header. The user-agent
// should be the same string that any commonly used browser sends. For information about user agents, see [RFC
// 2616](http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html). The following are examples of user-agent

// clientID - bing uses this header to provide users with consistent behavior across Bing API calls. Bing often
// flights new features and improvements, and it uses the client ID as a key for assigning traffic on different
// flights. If you do not use the same client ID for a user across multiple requests, then Bing may assign the
// user to multiple conflicting flights. Being assigned to multiple conflicting flights can lead to an
// inconsistent user experience. For example, if the second request has a different flight assignment than the
// first, the experience may be unexpected. Also, Bing can use the client ID to tailor web results to that
// client ID’s search history, providing a richer experience for the user. Bing also uses this header to help
// improve result rankings by analyzing the activity generated by a client ID. The relevance improvements help
// with better quality of results delivered by Bing APIs and in turn enables higher click-through rates for the
// API consumer. IMPORTANT: Although optional, you should consider this header required. Persisting the client
// ID across multiple requests for the same end user and device combination enables 1) the API consumer to
// receive a consistent user experience, and 2) higher click-through rates via better quality of results from
// the Bing APIs. Each user that uses your application on the device must have a unique, Bing generated client
// ID. If you do not include this header in the request, Bing generates an ID and returns it in the
// X-MSEdge-ClientID response header. The only time that you should NOT include this header in a request is the
// first time the user uses your app on that device. Use the client ID for each Bing API request that your app
// makes for this user on the device. Persist the client ID. To persist the ID in a browser app, use a
// persistent HTTP cookie to ensure the ID is used across all sessions. Do not use a session cookie. For other
// apps such as mobile apps, use the device's persistent storage to persist the ID. The next time the user uses
// your app on that device, get the client ID that you persisted. Bing responses may or may not include this
// header. If the response includes this header, capture the client ID and use it for all subsequent Bing
// requests for the user on that device. If you include the X-MSEdge-ClientID, you must not include cookies in
// the request.
// clientIP - the IPv4 or IPv6 address of the client device. The IP address is used to discover the user's
// location. Bing uses the location information to determine safe search behavior. Although optional, you are
// encouraged to always specify this header and the X-Search-Location header. Do not obfuscate the address (for
// example, by changing the last octet to 0). Obfuscating the address results in the location not being
// anywhere near the device's actual location, which may result in Bing serving erroneous results.
// location - a semicolon-delimited list of key/value pairs that describe the client's geographical location.
// Bing uses the location information to determine safe search behavior and to return relevant local content.
// Specify the key/value pair as <key>:<value>. The following are the keys that you use to specify the user's
// location. lat (required): The latitude of the client's location, in degrees. The latitude must be greater
// than or equal to -90.0 and less than or equal to +90.0. Negative values indicate southern latitudes and
// positive values indicate northern latitudes. long (required): The longitude of the client's location, in
// degrees. The longitude must be greater than or equal to -180.0 and less than or equal to +180.0. Negative
// values indicate western longitudes and positive values indicate eastern longitudes. re (required): The
// radius, in meters, which specifies the horizontal accuracy of the coordinates. Pass the value returned by
// the device's location service. Typical values might be 22m for GPS/Wi-Fi, 380m for cell tower triangulation,
// and 18,000m for reverse IP lookup. ts (optional): The UTC UNIX timestamp of when the client was at the
// location. (The UNIX timestamp is the number of seconds since January 1, 1970.) head (optional): The client's
// relative heading or direction of travel. Specify the direction of travel as degrees from 0 through 360,
// counting clockwise relative to true north. Specify this key only if the sp key is nonzero. sp (optional):
// The horizontal velocity (speed), in meters per second, that the client device is traveling. alt (optional):
// The altitude of the client device, in meters. are (optional): The radius, in meters, that specifies the
// vertical accuracy of the coordinates. Specify this key only if you specify the alt key. Although many of the
// keys are optional, the more information that you provide, the more accurate the location results are.
// Although optional, you are encouraged to always specify the user's geographical location. Providing the
// location is especially important if the client's IP address does not accurately reflect the user's physical
// location (for example, if the client uses VPN). For optimal results, you should include this header and the
// X-MSEdge-ClientIP header, but at a minimum, you should include this header.
// countryCode - a 2-character country code of the country where the results come from. This API supports only
// the United States market. If you specify this query parameter, it must be set to us. If you set this
// parameter, you must also specify the Accept-Language header. Bing uses the first supported language it finds
// from the languages list, and combine that language with the country code that you specify to determine the
// market to return results for. If the languages list does not include a supported language, Bing finds the
// closest language and market that supports the request, or it may use an aggregated or default market for the
// results instead of a specified one. You should use this query parameter and the Accept-Language query
// parameter only if you specify multiple languages; otherwise, you should use the mkt and setLang query
// parameters. This parameter and the mkt query parameter are mutually exclusive—do not specify both.
// category - the category of articles to return. For example, Sports articles or Entertainment articles. For a
// list of possible categories, see [News Categories by
// Market](https://docs.microsoft.com/en-us/rest/api/cognitiveservices/bing-news-api-v7-reference#categories-by-market).
// Use this parameter only with News Category API. If you do not specify this parameter, the response includes
// both: Headline articles typically published in the last 24 hours from any category and articles from each
// parent category (up to four articles). If the article is a headline, the article's headline field is set to
// true. By default, the response includes up to 12 headline articles. To specify the number of headline
// articles to return, set the
// [headlineCount](https://docs.microsoft.com/en-us/rest/api/cognitiveservices/bing-news-api-v7-reference#headlineCount)
// query parameter.
// count - the number of news articles to return in the response. The actual number delivered may be less than
// requested. The default is 10 and the maximum value is 100. The actual number delivered may be less than
// requested.You may use this parameter along with the offset parameter to page results. For example, if your
// user interface displays 20 articles per page, set count to 20 and offset to 0 to get the first page of
// results. For each subsequent page, increment offset by 20 (for example, 0, 20, 40). It is possible for
// multiple pages to include some overlap in results. If you do not specify the
// [category](https://docs.microsoft.com/en-us/rest/api/cognitiveservices/bing-news-api-v7-reference#category)
// parameter, Bing ignores this parameter.
// headlineCount - the number of headline articles to return in the response. The default is 12. Specify this
// parameter only if you do not specify the
// [category](https://docs.microsoft.com/en-us/rest/api/cognitiveservices/bing-news-api-v7-reference#category)
// parameter.
// market - the market where the results come from. Typically, mkt is the country where the user is making the
// request from. However, it could be a different country if the user is not located in a country where Bing
// delivers results. The market must be in the form <language code>-<country code>. For example, en-US. The
// string is case insensitive. For a list of possible market values, see [Market
// Codes](https://docs.microsoft.com/en-us/rest/api/cognitiveservices/bing-news-api-v7-reference#market-codes).
// NOTE: If known, you are encouraged to always specify the market. Specifying the market helps Bing route the
// request and return an appropriate and optimal response. If you specify a market that is not listed in
// [Market
// Codes](https://docs.microsoft.com/en-us/rest/api/cognitiveservices/bing-news-api-v7-reference#market-codes),
// Bing uses a best fit market code based on an internal mapping that is subject to change. This parameter and
// the [cc](https://docs.microsoft.com/en-us/rest/api/cognitiveservices/bing-news-api-v7-reference#cc) query
// parameter are mutually exclusive—do not specify both.
// offset - the zero-based offset that indicates the number of news to skip before returning news. The default
// is 0. The offset should be less than
// ([totalEstimatedMatches](https://docs.microsoft.com/en-us/rest/api/cognitiveservices/bing-news-api-v7-reference#news-totalmatches)
// - count). Use this parameter along with the count parameter to page results. For example, if your user
// interface displays 20 news per page, set count to 20 and offset to 0 to get the first page of results. For
// each subsequent page, increment offset by 20 (for example, 0, 20, 40). It is possible for multiple pages to
// include some overlap in results. If you do not specify the
// [category](https://docs.microsoft.com/en-us/rest/api/cognitiveservices/bing-news-api-v7-reference#category)
// parameter, Bing ignores this parameter.
// originalImage - a Boolean value that determines whether the image's contentUrl contains a URL that points to
// a thumbnail of the original article's image or the image itself. If the article includes an image, and this
// parameter is set to true, the image's contentUrl property contains a URL that you may use to download the
// original image from the publisher's website. Otherwise, if this parameter is false, the image's contentUrl
// and thumbnailUrl URLs both point to the same thumbnail image. Use this parameter only with the News Search
// API or News Category API. Trending Topics API ignore this parameter.
// safeSearch - filter news for adult content. The following are the possible filter values. Off: Return news
// articles with adult text, images, or videos. Moderate: Return news articles with adult text but not adult
// images or videos. Strict: Do not return news articles with adult text, images, or videos. If the request
// comes from a market that Bing's adult policy requires that safeSearch is set to Strict, Bing ignores the
// safeSearch value and uses Strict. If you use the site: query operator, there is the chance that the response
// may contain adult content regardless of what the safeSearch query parameter is set to. Use site: only if you
// are aware of the content on the site and your scenario supports the possibility of adult content.
// setLang - the language to use for user interface strings. Specify the language using the ISO 639-1 2-letter
// language code. For example, the language code for English is EN. The default is EN (English). Although
// optional, you should always specify the language. Typically, you set setLang to the same language specified
// by mkt unless the user wants the user interface strings displayed in a different language. This parameter
// and the
// [Accept-Language](https://docs.microsoft.com/en-us/rest/api/cognitiveservices/bing-news-api-v7-reference#acceptlanguage)
// header are mutually exclusive; do not specify both. A user interface string is a string that's used as a
// label in a user interface. There are few user interface strings in the JSON response objects. Also, any
// links to Bing.com properties in the response objects apply the specified language.
// textDecorations - a Boolean value that determines whether display strings contain decoration markers such as
// hit highlighting characters. If true, the strings may include markers. The default is false. To specify
// whether to use Unicode characters or HTML tags as the markers, see the
// [textFormat](https://docs.microsoft.com/en-us/rest/api/cognitiveservices/bing-news-api-v7-reference#textformat)
// query parameter. For information about hit highlighting, see [Hit
// Highlighting](https://docs.microsoft.com/azure/cognitive-services/bing-news-search/hit-highlighting).
// textFormat - the type of markers to use for text decorations (see the textDecorations query parameter).
// Possible values are Raw—Use Unicode characters to mark content that needs special formatting. The Unicode
// characters are in the range E000 through E019. For example, Bing uses E000 and E001 to mark the beginning
// and end of query terms for hit highlighting. HTML—Use HTML tags to mark content that needs special
// formatting. For example, use <b> tags to highlight query terms in display strings. The default is Raw. For
// display strings that contain escapable HTML characters such as <, >, and &, if textFormat is set to HTML,
// Bing escapes the characters as appropriate (for example, < is escaped to &lt;).

// the device's location service. Typical values might be 22m for GPS/Wi-Fi, 380m for cell tower triangulation,
// and 18,000m for reverse IP lookup. ts (optional): The UTC UNIX timestamp of when the client was at the
// location. (The UNIX timestamp is the number of seconds since January 1, 1970.) head (optional): The client's
// relative heading or direction of travel. Specify the direction of travel as degrees from 0 through 360,
// counting clockwise relative to true north. Specify this key only if the sp key is nonzero. sp (optional):
// The horizontal velocity (speed), in meters per second, that the client device is traveling. alt (optional):
// The altitude of the client device, in meters. are (optional): The radius, in meters, that specifies the
// vertical accuracy of the coordinates. Specify this key only if you specify the alt key. Although many of the
// keys are optional, the more information that you provide, the more accurate the location results are.
// Although optional, you are encouraged to always specify the user's geographical location. Providing the
// location is especially important if the client's IP address does not accurately reflect the user's physical
// location (for example, if the client uses VPN). For optimal results, you should include this header and the
// X-MSEdge-ClientIP header, but at a minimum, you should include this header.
// countryCode - a 2-character country code of the country where the results come from. This API supports only
// the United States market. If you specify this query parameter, it must be set to us. If you set this
// parameter, you must also specify the Accept-Language header. Bing uses the first supported language it finds
// from the languages list, and combine that language with the country code that you specify to determine the
// market to return results for. If the languages list does not include a supported language, Bing finds the
// closest language and market that supports the request, or it may use an aggregated or default market for the
// results instead of a specified one. You should use this query parameter and the Accept-Language query
// parameter only if you specify multiple languages; otherwise, you should use the mkt and setLang query
// parameters. This parameter and the mkt query parameter are mutually exclusive—do not specify both.
// count - the number of news articles to return in the response. The actual number delivered may be less than
// requested. The default is 10 and the maximum value is 100. The actual number delivered may be less than
// requested.You may use this parameter along with the offset parameter to page results. For example, if your
// user interface displays 20 articles per page, set count to 20 and offset to 0 to get the first page of
// results. For each subsequent page, increment offset by 20 (for example, 0, 20, 40). It is possible for
// multiple pages to include some overlap in results.
// freshness - filter news by the date and time that Bing discovered the news. The following are the possible
// filter values. Day: Return news discovered within the last 24 hours. Week: Return news discovered within the
// last 7 days. Month: Return news discovered within the last 30 days. Use this parameter only with the News
// Search API. Do not specify this parameter when calling the News Category API or the Trending Topics API.
// market - the market where the results come from. Typically, mkt is the country where the user is making the
// request from. However, it could be a different country if the user is not located in a country where Bing
// delivers results. The market must be in the form <language code>-<country code>. For example, en-US. The
// string is case insensitive. For a list of possible market values, see [Market
// Codes](https://docs.microsoft.com/en-us/rest/api/cognitiveservices/bing-news-api-v7-reference#market-codes).
// NOTE: If known, you are encouraged to always specify the market. Specifying the market helps Bing route the
// request and return an appropriate and optimal response. If you specify a market that is not listed in
// [Market
// Codes](https://docs.microsoft.com/en-us/rest/api/cognitiveservices/bing-news-api-v7-reference#market-codes),
// Bing uses a best fit market code based on an internal mapping that is subject to change. This parameter and
// the [cc](https://docs.microsoft.com/en-us/rest/api/cognitiveservices/bing-news-api-v7-reference#cc) query
// parameter are mutually exclusive—do not specify both.
// offset - the zero-based offset that indicates the number of news to skip before returning news. The default
// is 0. The offset should be less than
// ([totalEstimatedMatches](https://docs.microsoft.com/en-us/rest/api/cognitiveservices/bing-news-api-v7-reference#news-totalmatches)
// - count). Use this parameter along with the count parameter to page results. For example, if your user
// interface displays 20 news per page, set count to 20 and offset to 0 to get the first page of results. For
// each subsequent page, increment offset by 20 (for example, 0, 20, 40). It is possible for multiple pages to
// include some overlap in results.
// originalImage - a Boolean value that determines whether the image's contentUrl contains a URL that points to
// a thumbnail of the original article's image or the image itself. If the article includes an image, and this
// parameter is set to true, the image's contentUrl property contains a URL that you may use to download the
// original image from the publisher's website. Otherwise, if this parameter is false, the image's contentUrl
// and thumbnailUrl URLs both point to the same thumbnail image. Use this parameter only with the News Search
// API. Do not specify this parameter when calling the Trending Topics API or News Category API.
// safeSearch - filter news for adult content. The following are the possible filter values. Off: Return news
// articles with adult text, images, or videos. Moderate: Return news articles with adult text but not adult
// images or videos. Strict: Do not return news articles with adult text, images, or videos. If the request
// comes from a market that Bing's adult policy requires that safeSearch is set to Strict, Bing ignores the
// safeSearch value and uses Strict. If you use the site: query operator, there is the chance that the response
// may contain adult content regardless of what the safeSearch query parameter is set to. Use site: only if you
// are aware of the content on the site and your scenario supports the possibility of adult content.
// setLang - the language to use for user interface strings. Specify the language using the ISO 639-1 2-letter
// language code. For example, the language code for English is EN. The default is EN (English). Although
// optional, you should always specify the language. Typically, you set setLang to the same language specified
// by mkt unless the user wants the user interface strings displayed in a different language. This parameter
// and the
// [Accept-Language](https://docs.microsoft.com/en-us/rest/api/cognitiveservices/bing-news-api-v7-reference#acceptlanguage)
// header are mutually exclusive; do not specify both. A user interface string is a string that's used as a
// label in a user interface. There are few user interface strings in the JSON response objects. Also, any
// links to Bing.com properties in the response objects apply the specified language.
// sortBy - the order to return the news in. The following are the possible case-insensitive values. Date: If
// the request is through the News Search API, the response returns news articles sorted by date from the most
// recent to the oldest. If the request is through the News Trending Topics API, the response returns trending
// topics sorted by date from the most recent to the oldest.
// textDecorations - a Boolean value that determines whether display strings contain decoration markers such as
// hit highlighting characters. If true, the strings may include markers. The default is false. To specify
// whether to use Unicode characters or HTML tags as the markers, see the
// [textFormat](https://docs.microsoft.com/en-us/rest/api/cognitiveservices/bing-news-api-v7-reference#textformat)
// query parameter. For information about hit highlighting, see [Hit
// Highlighting](https://docs.microsoft.com/azure/cognitive-services/bing-news-search/hit-highlighting).
// textFormat - the type of markers to use for text decorations (see the textDecorations query parameter).
// Possible values are Raw—Use Unicode characters to mark content that needs special formatting. The Unicode
// characters are in the range E000 through E019. For example, Bing uses E000 and E001 to mark the beginning
// and end of query terms for hit highlighting. HTML—Use HTML tags to mark content that needs special
// formatting. For example, use <b> tags to highlight query terms in display strings. The default is Raw. For
// display strings that contain escapable HTML characters such as <, >, and &, if textFormat is set to HTML,
// Bing escapes the characters as appropriate (for example, < is escaped to &lt;).

// query parameter are mutually exclusive; do not specify both. If you set this header, you must also specify

// should be the same string that any commonly used browser sends. For information about user agents, see [RFC

// clientID - bing uses this header to provide users with consistent behavior across Bing API calls. Bing often
// flights new features and improvements, and it uses the client ID as a key for assigning traffic on different
// flights. If you do not use the same client ID for a user across multiple requests, then Bing may assign the
// user to multiple conflicting flights. Being assigned to multiple conflicting flights can lead to an
// inconsistent user experience. For example, if the second request has a different flight assignment than the
// first, the experience may be unexpected. Also, Bing can use the client ID to tailor web results to that
// client ID’s search history, providing a richer experience for the user. Bing also uses this header to help
// improve result rankings by analyzing the activity generated by a client ID. The relevance improvements help
// with better quality of results delivered by Bing APIs and in turn enables higher click-through rates for the
// API consumer. IMPORTANT: Although optional, you should consider this header required. Persisting the client
// ID across multiple requests for the same end user and device combination enables 1) the API consumer to
// receive a consistent user experience, and 2) higher click-through rates via better quality of results from
// the Bing APIs. Each user that uses your application on the device must have a unique, Bing generated client
// ID. If you do not include this header in the request, Bing generates an ID and returns it in the
// X-MSEdge-ClientID response header. The only time that you should NOT include this header in a request is the
// first time the user uses your app on that device. Use the client ID for each Bing API request that your app
// makes for this user on the device. Persist the client ID. To persist the ID in a browser app, use a
// persistent HTTP cookie to ensure the ID is used across all sessions. Do not use a session cookie. For other
// apps such as mobile apps, use the device's persistent storage to persist the ID. The next time the user uses
// your app on that device, get the client ID that you persisted. Bing responses may or may not include this
// header. If the response includes this header, capture the client ID and use it for all subsequent Bing
// requests for the user on that device. If you include the X-MSEdge-ClientID, you must not include cookies in
// the request.
// clientIP - the IPv4 or IPv6 address of the client device. The IP address is used to discover the user's
// location. Bing uses the location information to determine safe search behavior. Although optional, you are
// encouraged to always specify this header and the X-Search-Location header. Do not obfuscate the address (for
// example, by changing the last octet to 0). Obfuscating the address results in the location not being
// anywhere near the device's actual location, which may result in Bing serving erroneous results.
// location - a semicolon-delimited list of key/value pairs that describe the client's geographical location.
// Bing uses the location information to determine safe search behavior and to return relevant local content.
// Specify the key/value pair as <key>:<value>. The following are the keys that you use to specify the user's
// location. lat (required): The latitude of the client's location, in degrees. The latitude must be greater
// than or equal to -90.0 and less than or equal to +90.0. Negative values indicate southern latitudes and
// positive values indicate northern latitudes. long (required): The longitude of the client's location, in
// degrees. The longitude must be greater than or equal to -180.0 and less than or equal to +180.0. Negative
// values indicate western longitudes and positive values indicate eastern longitudes. re (required): The
// radius, in meters, which specifies the horizontal accuracy of the coordinates. Pass the value returned by
// the device's location service. Typical values might be 22m for GPS/Wi-Fi, 380m for cell tower triangulation,
// and 18,000m for reverse IP lookup. ts (optional): The UTC UNIX timestamp of when the client was at the
// location. (The UNIX timestamp is the number of seconds since January 1, 1970.) head (optional): The client's
// relative heading or direction of travel. Specify the direction of travel as degrees from 0 through 360,
// counting clockwise relative to true north. Specify this key only if the sp key is nonzero. sp (optional):
// The horizontal velocity (speed), in meters per second, that the client device is traveling. alt (optional):
// The altitude of the client device, in meters. are (optional): The radius, in meters, that specifies the
// vertical accuracy of the coordinates. Specify this key only if you specify the alt key. Although many of the
// keys are optional, the more information that you provide, the more accurate the location results are.
// Although optional, you are encouraged to always specify the user's geographical location. Providing the
