不，client.Post是90％不需要取消请求的用例的便捷包装。
重新实现您的客户端以访问具有CancelRequest（）函数的基础传输对象可能就足够了。
只是一个简单的例子：
package mainimport ( "log" "net/http" "time")func main() { req, _ := http.NewRequest("GET", "http://google.com", nil) tr := &http.Transport{} // TODO: copy defaults from http.DefaultTransport client := &http.Client{Transport: tr} c := make(chan error, 1) go func() { resp, err := client.Do(req) // handle response ... _ = resp c <- err }() // Simulating user cancel request channel user := make(chan struct{}, 0) go func() { time.Sleep(100 * time.Millisecond) user <- struct{}{} }() for { select { case <-user: log.Println("Cancelling request") tr.CancelRequest(req) case err := <-c: log.Println("Client finished:", err) return } }}
