Go语言（服务器开发）：实现最简单的HTTP GET/POST接口

package webserver

import (
"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:" + password
fmt.Println(s)

if userName == "zhangsan" && password == "123456" {
result.Code = 100
result.Message = "登录成功"
} else {
result.Code = 101
result.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))
}

package webserver

type BaseJsonBean struct {
Code    int         `json:"code"`
Data    interface{} `json:"data"`
Message string      `json:"message"`
}

func NewBaseJsonBean() *BaseJsonBean {
return &BaseJsonBean{}
}
