這是一個建立於 的文章，其中的資訊可能已經有所發展或是發生改變。

檔案服務server.go

package mainimport ("io""net/http""os")func uploadHandler(w http.ResponseWriter, r *http.Request) {file, err := os.Create("./newFile")if err != nil {panic(err)}_, err = io.Copy(file, r.Body)if err != nil {panic(err)}w.Write([]byte("upload success"))}func main() {http.HandleFunc("/upload", uploadHandler)http.ListenAndServe(":5050", nil)}

檔案傳送client.go

package mainimport ("fmt""io/ioutil""net/http""os")func main() {file, err := os.Open("./a.txt")if err != nil {panic(err)}defer file.Close()res, err := http.Post("http://127.0.0.1:5050/upload", "binary/octet-stream", file)if err != nil {panic(err)}defer res.Body.Close()message, _ := ioutil.ReadAll(res.Body)fmt.Printf(string(message))}
