示例1: fail

func fail(sc *httputil.ServerConn, req *http.Request, code int, msg string) {
	resp := &http.Response{
		StatusCode:    code,
		ProtoMajor:    1,
		ProtoMinor:    0,
		Request:       req,
		Body:          ioutil.NopCloser(bytes.NewBufferString(msg)),
		ContentLength: int64(len(msg)),
	}
	sc.Write(req, resp)
}
