你可以做这样的事情。proxy.Transport用另一个实现来包装http.RoundtripperRoundTrip 响应所需的时间。我认为这通常会向您显示“响应时间”。不是“请求时间”，因为仍然可以从响应中读取正文，因此请求可能仍在进行中，但这应该大致显示服务器响应请求所需的时间。package mainimport ( "fmt" "net/http" "net/http/httputil" "net/url" "time")func main() { url, _ := url.Parse("https://stackoverflow.com") proxy := httputil.NewSingleHostReverseProxy(url) proxy.Transport = NewTimingRoundtripper(http.DefaultTransport)}type TimingRoundtripper struct { transport http.RoundTripper}func NewTimingRoundtripper(transport http.RoundTripper) http.RoundTripper { return TimingRoundtripper{transport: transport}}func (rt TimingRoundtripper) RoundTrip(r *http.Request) (resp *http.Response, err error) { start := time.Now() resp, err = rt.transport.RoundTrip(r) fmt.Println("request", r.URL, time.Since(start)) return resp, err}如果您想传递一个自定义*tls.Config（如下所示），您可以创建一个具有与相同参数http.DefaultTransport但具有自定义的新传输*tls.Config。 var myTransport http.RoundTripper = &http.Transport{ Proxy: http.ProxyFromEnvironment, DialContext: (&net.Dialer{ Timeout: 30 * time.Second, KeepAlive: 30 * time.Second, }).DialContext, ForceAttemptHTTP2: true, MaxIdleConns: 100, IdleConnTimeout: 90 * time.Second, TLSHandshakeTimeout: 10 * time.Second, ExpectContinueTimeout: 1 * time.Second, TLSClientConfig: &tls.Config{InsecureSkipVerify: true}, }然后像这样初始化：proxy.Transport = NewTimingRoundtripper(myTransport)
