Let's Go系列–实战Cookie与Session

在Gin中使用Cookie

下面代码是如何使用Cookie的样例，包括创建Cookie、获取Cookie和删除Cookie。

package main

import (
	"fmt"
	"net/http"

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

func main() {
	router := gin.Default()

	router.GET("/set-cookie", func(ctx *gin.Context) {
		ctx.SetCookie("sessionid", "fuck cookie", 3600, "/", "localhost", false, false)
		ctx.JSON(http.StatusOK, gin.H{
			"msg": "set-cookie ok",
		})
	})

	router.GET("/get-cookie", func(ctx *gin.Context) {
		val, err := ctx.Cookie("sessionid")
		if err == nil {
			ctx.JSON(http.StatusOK, gin.H{
				"msg": fmt.Sprintf("get cookie :sessionid=%v", val),
			})
		} else {
			ctx.JSON(http.StatusOK, gin.H{
				"msg": fmt.Sprintf("get cookie error:%v", err),
			})
		}
	})

	router.GET("/del-cookie", func(ctx *gin.Context) {
		ctx.SetCookie("sessionid", "", -1, "/", "localhost", false, false)
		ctx.JSON(http.StatusOK, gin.H{
			"msg": "del-cookie ok",
		})
	})

	if err := router.Run(":8001"); err != nil {
		panic(err)
	}
}
