type ResponseRecorder struct {// Code is the HTTP response code set by WriteHeader.//// Note that if a Handler never calls WriteHeader or Write,// this might end up being 0, rather than the implicit// http.StatusOK. To get the implicit value, use the Result// method.Codeint// HeaderMap contains the headers explicitly set by the Handler.// It is an internal detail.//// Deprecated: HeaderMap exists for historical compatibility// and should not be used. To access the headers returned by a handler,// use the Response.Header map as returned by the Result method.HeaderMaphttp.Header// Body is the buffer to which the Handler's Write calls are sent.// If nil, the Writes are silently discarded.Body *bytes.Buffer// Flushed is whether the Handler called Flush.Flushedbool// contains filtered or unexported fields}

funcNewRecorder¶

func NewRecorder() *ResponseRecorder

NewRecorder returns an initializedResponseRecorder.

func (*ResponseRecorder)Flush¶

func (rw *ResponseRecorder) Flush()

Flush implementshttp.Flusher. To test whether Flush wascalled, see rw.Flushed.

func (*ResponseRecorder)Header¶

func (rw *ResponseRecorder) Header()http.Header

Header implementshttp.ResponseWriter. It returns the responseheaders to mutate within a handler. To test the headers that werewritten after a handler completes, use theResponseRecorder.Result method and seethe returned Response value's Header.

func (*ResponseRecorder)Result¶

func (rw *ResponseRecorder) Result() *http.Response

Result returns the response generated by the handler.

The returned Response will have at least its StatusCode,Header, Body, and optionally Trailer populated.More fields may be populated in the future, so callers shouldnot DeepEqual the result in tests.

The Response.Header is a snapshot of the headers at the time of thefirst write call, or at the time of this call, if the handler neverdid a write.

The Response.Body is guaranteed to be non-nil and Body.Read call isguaranteed to not return any error other thanio.EOF.

Result must only be called after the handler has finished running.

func (*ResponseRecorder)Write¶

func (rw *ResponseRecorder) Write(buf []byte) (int,error)

Write implements http.ResponseWriter. The data in buf is written torw.Body, if not nil.

func (*ResponseRecorder)WriteHeader¶

func (rw *ResponseRecorder) WriteHeader(codeint)

WriteHeader implementshttp.ResponseWriter.

func (*ResponseRecorder)WriteString¶

func (rw *ResponseRecorder) WriteString(strstring) (int,error)

WriteString implementsio.StringWriter. The data in str is writtento rw.Body, if not nil.
