golang创建http服务器，实现GET和POST请求

代码

package main

import (
    "github.com/gin-gonic/gin"
    "net/http"
    "strconv"
)

var id int = 0

// get处理函数
func t1_get(c *gin.Context) {
    name := c.Query("name")
    id += 1
    c.JSON(http.StatusOK, gin.H{
        "title": "get",
        "msg": "hello " + name + " you are the " + strconv.Itoa(id) + "th guest !",
    })
}

// 定义json序列化结构
type PostData struct {
    Name    string `json:"name"`
    Tel     string `json:"tel"`
    Email   string `json:"email"`
}

// post处理函数
func t1_post(c *gin.Context) {
    var postData PostData
    // 解析body部分
    if err := c.ShouldBindBodyWithJSON(&postData); err != nil {
        c.JSON(http.StatusBadRequest, gin.H{
            "error": err.Error(),
        })
        return
    }

    id += 1
    // 设置返回值
    c.JSON( http.StatusOK, gin.H{
        "title": "post",
        "content": postData,
        "msg": strconv.Itoa(id) + "th guest !",
    })
}


func main() {

    // 创建服务
    serv := gin.Default()
    serv.UseH2C = true

    // 创建路由
    route := serv.Group("/test")

    // 添加两个路由
    route.GET("/t1", t1_get)
    route.POST("/t1", t1_post)

    // 启动
    serv.Run(":3322")
}
