func BytesToString

func BytesToString(b []byte) string

BytesToString converts byte slice to string without a memory allocation.

func CleanPath

func CleanPath(p string) string

CleanPath is the URL version of path.Clean, it returns a canonical URL path for p, eliminating . and .. elements.

The following rules are applied iteratively until no further processing can be done:

  1. Replace multiple slashes with a single slash.
  2. Eliminate each . path name element (the current directory).
  3. Eliminate each inner .. path name element (the parent directory) along with the non-.. element that precedes it.
  4. Eliminate .. elements that begin a rooted path: that is, replace "/.." by "/" at the beginning of a path.

If the result of this process is an empty string, "/" is returned

type Router

type Router struct {

	// Enables automatic redirection if the current route can't be matched but a
	// handler for the path with (without) the trailing slash exists.
	// For example if /foo/ is requested but a route only exists for /foo, the
	// client is redirected to /foo with http status code 301 for GET requests
	// and 307 for all other request methods.
	RedirectTrailingSlash bool

	// If enabled, the router tries to fix the current request path, if no
	// handle is registered for it.
	// First superfluous path elements like ../ or // are removed.
	// Afterwards the router does a case-insensitive lookup of the cleaned path.
	// If a handle can be found for this route, the router makes a redirection
	// to the corrected path with status code 301 for GET requests and 307 for
	// all other request methods.
	// For example /FOO and /..//Foo could be redirected to /foo.
	// RedirectTrailingSlash is independent of this option.
	RedirectFixedPath bool

	// If enabled, the router checks if another method is allowed for the
	// current route, if the current request can not be routed.
	// If this is the case, the request is answered with 'Method Not Allowed'
	// and HTTP status code 405.
	// If no other Method is allowed, the request is delegated to the NotFound
	// handler.
	HandleMethodNotAllowed bool

	// If enabled, the router automatically replies to OPTIONS requests.
	// Custom OPTIONS handlers take priority over automatic replies.
	HandleOPTIONS bool

	// Configurable http.Handler which is called when no matching route is
	// found. If it is not set, http.NotFound is used.
	NotFound http.Handler

	// Configurable http.Handler which is called when a request
	// cannot be routed and HandleMethodNotAllowed is true.
	// If it is not set, http.Error with http.StatusMethodNotAllowed is used.
	// The "Allow" header with allowed request methods is set before the handler
	// is called.
	MethodNotAllowed http.Handler

	// Function to handle panics recovered from http handlers.
	// It should be used to generate a error page and return the http error code
	// 500 (Internal Server Error).
	// The handler can be used to keep your server from crashing because of
	// unrecovered panics.
	PanicHandler func(http.ResponseWriter, *http.Request, interface{})
	// contains filtered or unexported fields

Router is a http.Handler which can be used to dispatch requests to different handler functions via configurable routes

func NewRouter

func NewRouter() *Router

NewRouter returns a new initialized Router. Path auto-correction, including trailing slashes, is enabled by default.

func (*Router) DELETE

func (r *Router) DELETE(path string, handle Handle)

DELETE is a shortcut for router.Handle("DELETE", path, handle)

func (*Router) GET

func (r *Router) GET(path string, handle Handle)

GET is a shortcut for router.Handle("GET", path, handle)

func (*Router) HEAD

func (r *Router) HEAD(path string, handle Handle)

HEAD is a shortcut for router.Handle("HEAD", path, handle)

func (*Router) Handle

func (r *Router) Handle(method, path string, handle Handle)

Handle registers a new request handle with the given path and method.

For GET, POST, PUT, PATCH and DELETE requests the respective shortcut functions can be used.

This function is intended for bulk loading and to allow the usage of less frequently used, non-standardized or custom methods (e.g. for internal communication with a proxy).

func (*Router) Handler

func (r *Router) Handler(method, path string, handler http.Handler)

Handler is an adapter which allows the usage of an http.Handler as a request handle. With go 1.7+, the Params will be available in the request context under ParamsKey.

func (*Router) HandlerFunc

func (r *Router) HandlerFunc(method, path string, handler http.HandlerFunc)

HandlerFunc is an adapter which allows the usage of an http.HandlerFunc as a request handle.

func (*Router) Lookup

func (r *Router) Lookup(method, path string) (Handle, map[string]string, bool)

Lookup allows the manual lookup of a method + path combo. This is e.g. useful to build a framework around this router. If the path was found, it returns the handle function and the path parameter values. Otherwise the third return value indicates whether a redirection to the same path with an extra / without the trailing slash should be performed.

func (*Router) OPTIONS

func (r *Router) OPTIONS(path string, handle Handle)

OPTIONS is a shortcut for router.Handle("OPTIONS", path, handle)

func (*Router) PATCH

func (r *Router) PATCH(path string, handle Handle)

PATCH is a shortcut for router.Handle("PATCH", path, handle)

func (*Router) POST

func (r *Router) POST(path string, handle Handle)

POST is a shortcut for router.Handle("POST", path, handle)

func (*Router) PUT

func (r *Router) PUT(path string, handle Handle)

PUT is a shortcut for router.Handle("PUT", path, handle)

func (*Router) ServeFiles

func (r *Router) ServeFiles(path string, root http.FileSystem)

ServeFiles serves files from the given file system root. The path must end with "/*filepath", files are then served from the local path /defined/root/dir/*filepath. For example if root is "/etc" and *filepath is "passwd", the local file "/etc/passwd" would be served. Internally a http.FileServer is used, therefore http.NotFound is used instead of the Router's NotFound handler. To use the operating system's file system implementation, use http.Dir:

router.ServeFiles("/src/*filepath", http.Dir("/var/www"))

func (*Router) ServeHTTP

func (r *Router) ServeHTTP(w http.ResponseWriter, req *http.Request)

ServeHTTP makes the router implement the http.Handler interface.
