Go语言（服务器开发）：实现最简单的HTTP GET/POST接口

来源：互联网发布：vr全景拍摄软件编辑：程序博客网时间：2024/04/28 17:59

Go语言提供了http包，可以很轻松的开发http接口。以下为示例代码：

package webserverimport ("encoding/json""fmt""net/http""time")func WebServerBase() {fmt.Println("This is webserver base!")//第一个参数为客户端发起http请求时的接口名，第二个参数是一个func，负责处理这个请求。http.HandleFunc("/login", loginTask)//服务器要监听的主机地址和端口号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...")//模拟延时time.Sleep(time.Second * 2)//获取客户端通过GET/POST方式传递的参数req.ParseForm()param_userName, found1 := req.Form["userName"]param_password, found2 := req.Form["password"]if !(found1 && found2) {fmt.Fprint(w, "请勿非法访问")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 = "登录成功"} else {result.Code = 101result.Message = "用户名或密码不正确"}        //向客户端返回JSON数据bytes, _ := json.Marshal(result)fmt.Fprint(w, string(bytes))}

NewBaseJsonBean用于创建一个struct对象:

package webservertype BaseJsonBean struct {Code    int         `json:"code"`Data    interface{} `json:"data"`Message string      `json:"message"`}func NewBaseJsonBean() *BaseJsonBean {return &BaseJsonBean{}}
