Go语言Web知识（一） 认识Gin框架

入门代码

package main

import "github.com/gin-gonic/gin"

func main()  {
	r := gin.Default()
	r.GET("/ping", func(c *gin.Context) {
		c.JSON(200,gin.H{
			"message":"pong",
		})
	})
	r.Run(":8080")
}

curl http://localhost:8080/ping

返回 {"meseege" : "pong"}

接收Get与Post方式传输的参数

package main

import (
	"github.com/gin-gonic/gin"
	"fmt"
)

func main() {
	r := gin.Default()
	r.GET("/login", login)
	r.POST("/form_post", formPost)
	r.Run(":8080")
}

func login(c *gin.Context) {
	username := c.Query("username")
	password := c.Query("password")
	fmt.Println(username, password)
}

func formPost(c *gin.Context) {
	message:= c.PostForm("message")
	nick := c.DefaultPostForm("nick", "anonymous")
	c.JSON(200, gin.H{
		"status":  "posted",
		"message": message,
		"nick":    nick,
	})
}
