Functions

func CombinedLoggingHandler

func CombinedLoggingHandler(out io.Writer, h http.Handler) http.Handler

CombinedLoggingHandler return a http.Handler that wraps h and logs requests to out in Apache Combined Log Format.

See http://httpd.apache.org/docs/2.2/logs.html#combined for a description of this format.

LoggingHandler always sets the ident field of the log to -

func CompressHandler

func CompressHandler(h http.Handler) http.Handler

func ContentTypeHandler

func ContentTypeHandler(h http.Handler, contentTypes ...string) http.Handler

ContentTypeHandler wraps and returns a http.Handler, validating the request content type is acompatible with the contentTypes list. It writes a HTTP 415 error if that fails.

Only PUT, POST, and PATCH requests are considered.

func HTTPMethodOverrideHandler

func HTTPMethodOverrideHandler(h http.Handler) http.Handler

HTTPMethodOverrideHandler wraps and returns a http.Handler which checks for the X-HTTP-Method-Override header or the _method form key, and overrides (if valid) request.Method with its value.

This is especially useful for http clients that don't support many http verbs. It isn't secure to override e.g a GET to a POST, so only POST requests are considered. Likewise, the override method can only be a "write" method: PUT, PATCH or DELETE.

Form method takes precedence over header method.

func LoggingHandler

func LoggingHandler(out io.Writer, h http.Handler) http.Handler

LoggingHandler return a http.Handler that wraps h and logs requests to out in Apache Common Log Format (CLF).

See http://httpd.apache.org/docs/2.2/logs.html#common for a description of this format.

LoggingHandler always sets the ident field of the log to -

Types

type MethodHandler

type MethodHandler map[string]http.Handler

MethodHandler is an http.Handler that dispatches to a handler whose key in the MethodHandler's map matches the name of the HTTP request's method, eg: GET

If the request's method is OPTIONS and OPTIONS is not a key in the map then the handler responds with a status of 200 and sets the Allow header to a comma-separated list of available methods.

If the request's method doesn't match any of its keys the handler responds with a status of 406, Method not allowed and sets the Allow header to a comma-separated list of available methods.

func (MethodHandler) ServeHTTP

func (h MethodHandler) ServeHTTP(w http.ResponseWriter, req *http.Request)
