Go language (Server development): Implementing the simplest HTTP Get/post interface

Source: Internet
Author: User

The Go language provides an HTTP package that makes it easy to develop an HTTP interface. The following is the sample code:

Package Webserverimport ("Encoding/json" "FMT" "Net/http" "Time") func webserverbase () {fmt. Println ("This is webserver base!") The first parameter is the interface name when the client initiates an HTTP request, and the second parameter is a func that is responsible for processing the request. http. Handlefunc ("/login", Logintask)//server to listen on the host address and port number err: = http. Listenandserve ("192.168.1.27:8081", nil) if err! = Nil {fmt. PRINTLN ("Listenandserve error:", err.) Error ())}}func Logintask (w http. Responsewriter, req *http. Request) {fmt. Println ("Logintask is running ...")//analog delay time. Sleep (time. Second * 2)//Gets the parameters passed by the client through Get/post mode Req.parseform () param_username, Found1: = req. form["UserName"]param_password, Found2: = req. form["Password"]if! (Found1 && Found2) {FMT. Fprint (W, "Do not access illegally") Return}result: = Newbasejsonbean () UserName: = Param_username[0]password: = param_password[0]s: = " UserName: "+ userName +", Password: "+ passwordfmt. PRINTLN (s) if userName = = "Zhangsan" && password = = "123456" {result. Code = 100result. Message = "Login Succeeded"} else {result. Code = 101result. Message = "Username or password is incorrect"}       //to GuestThe client returns the JSON data bytes, _: = json. Marshal (Result) fmt. Fprint (w, string (bytes))}

Newbasejsonbean is used to create a struct object:

Package Webservertype basejsonbean struct {code    int         ' JSON: ' Code ' ' Data    interface{} ' JSON: ' Data ' ' Message ' String      ' JSON: ' message ' '}func Newbasejsonbean () *basejsonbean {return &basejsonbean{}}
