可以使用 golang 内置的 net/http 包来实现代理转发。具体实现方法如下： ```go package main import ( "fmt" "log" "net/http" ) func handler(w http.ResponseWriter, r *http.Request) { // 构造请求 req, err := http.NewRequest(r.Method, r.URL.String(), r.Body) if err != nil { http.Error(w, err.Error(), http.StatusBadRequest) return } // 设置请求头 for key, value := range r.Header { req.Header.Set(key, value[0]) } // 发送请求 client := &http.Client{} resp, err := client.Do(req) if err != nil { http.Error(w, err.Error(), http.StatusInternalServerError) return } defer resp.Body.Close() // 处理响应 for key, value := range resp.Header { w.Header().Set(key, value[0]) } w.WriteHeader(resp.StatusCode) _, err = w.Write([]byte("")) if err != nil { http.Error(w, err.Error(), http.StatusInternalServerError) return } } func main() { http.HandleFunc("/", handler) fmt.Println("Server listening on :8080") log.Fatal(http.ListenAndServe(":8080", nil)) } ```
