    // WildcardCharacter is a special character for wildcard path parameter.
    WildcardCharacter = '*'

    // TerminationCharacter is a special character for end of path.
    TerminationCharacter = '#'

    // SeparatorCharacter separates path segments.
    SeparatorCharacter = '/'

Variables

NotFound replies to the request with an HTTP 404 not found error. NotFound is called when unknown HTTP method or a handler not found. If you want to use the your own NotFound handler, please overwrite this variable.

var NotFound = func(w http.ResponseWriter, r *http.Request, _ Params) {
    http.NotFound(w, r)
}

func NextSeparator

func NextSeparator(path string, start int) int

NextSeparator returns an index of next separator in path.

type Handler

Handler represents a handler of HTTP request.

type Handler struct {
    // Method is an HTTP method.
    Method string

    // Path is a routing path for handler.
    Path string

    // Func is a function of handler of HTTP request.
    Func HandlerFunc
}

type HandlerFunc

The HandlerFunc type is aliased to type of handler function.

type HandlerFunc func(w http.ResponseWriter, r *http.Request, params Params)

type Mux

Mux represents a multiplexer for HTTP request.

type Mux struct{}

func NewMux

func NewMux() *Mux

NewMux returns a new Mux.

func (*Mux) Build

func (m *Mux) Build(handlers []Handler) (http.Handler, error)

Build builds a http.Handler.

func (*Mux) GET

func (m *Mux) GET(path string, handler HandlerFunc) Handler

GET is shorthand of Mux.Handler("GET", path, handler).

func (*Mux) HEAD

func (m *Mux) HEAD(path string, handler HandlerFunc) Handler

HEAD is shorthand of Mux.Handler("HEAD", path, handler).

func (*Mux) Handler

func (m *Mux) Handler(method, path string, handler HandlerFunc) Handler

Handler returns a handler for HTTP method.

func (*Mux) POST

func (m *Mux) POST(path string, handler HandlerFunc) Handler

POST is shorthand of Mux.Handler("POST", path, handler).

func (*Mux) PUT

func (m *Mux) PUT(path string, handler HandlerFunc) Handler

PUT is shorthand of Mux.Handler("PUT", path, handler).

type Param

Param represents name and value of path parameter.

type Param struct {
    Name  string
    Value string
}

type Params

Params represents the name and value of path parameters.

type Params []Param

func (Params) Get

func (ps Params) Get(name string) string

Get gets the first value associated with the given name. If there are no values associated with the key, Get returns "".

type Record

Record represents a record data for router construction.

type Record struct {
    // Key for router construction.
    Key string

    // Result value for Key.
    Value interface{}
}

func NewRecord

func NewRecord(key string, value interface{}) Record

NewRecord returns a new Record.

type Router

Router represents a URL router.

type Router struct {

    // SizeHint expects the maximum number of path parameters in records to Build.
    // SizeHint will be used to determine the capacity of the memory to allocate.
    // By default, SizeHint will be determined from given records to Build.
    SizeHint int
    // contains filtered or unexported fields
}

func New

func New() *Router

New returns a new Router.

func (*Router) Build

func (rt *Router) Build(records []Record) error

Build builds URL router from records.

func (*Router) Lookup

func (rt *Router) Lookup(path string) (data interface{}, params Params, found bool)

Lookup returns data and path parameters that associated with path. params is a slice of the Param that arranged in the order in which parameters appeared. e.g. when built routing path is "/path/to/:id/:name" and given path is "/path/to/1/alice". params order is [{"id": "1"}, {"name": "alice"}], not [{"name": "alice"}, {"id": "1"}].
