Types

type Middleware

type Middleware = func(next http.Handler) http.Handler

func ApplyIf

func ApplyIf(cond func(r *http.Request) bool, mw Middleware) Middleware

ApplyIf returns new Middlware that wraps `next` handler if `cond` returns true otherwise just delegates to `next` handler.

You can determine `cond` result according to incoming *http.Request's value.

func Stack

func Stack(middlewares ...Middleware) Middleware

Stack returns new Middleware that runs `middlewares` sequentially.

It is useful for applying multiple middlewares and reusing them.

type TeeResponseWriter

type TeeResponseWriter struct {
	// contains filtered or unexported fields
}

TeeResponseWriter is an http.ResponseWriter implementation and writes response body into original http.ResponseWriter and given io.Writer.

You can use TeeResponseWriter for capturing sent response body in http.Handler.

func NewTeeResponseWriter

func NewTeeResponseWriter(rw http.ResponseWriter, buf io.Writer) *TeeResponseWriter

func (*TeeResponseWriter) Header

func (w *TeeResponseWriter) Header() http.Header

func (*TeeResponseWriter) StatusCode

func (w *TeeResponseWriter) StatusCode() int

StatusCode returns captured response status.

The return value may be zero if no response sent.

func (*TeeResponseWriter) Write

func (w *TeeResponseWriter) Write(b []byte) (int, error)

func (*TeeResponseWriter) WriteHeader

func (w *TeeResponseWriter) WriteHeader(statusCode int)
