使用go gin来操作cookie的讲解

package main
import (
  "github.com/gin-gonic/gin"
)
func main() {
  router := gin.Default();
  router.GET("/read_cookie", func(context *gin.Context) {
    val, _ := context.Cookie("name")
    context.String(200, "Cookie:%s", val) 
  })
  router.GET("/write_cookie", func(context *gin.Context) {
    context.SetCookie("name", "Shimin Li", 10, "/", "localhost", false, true)
  })
  router.GET("/clear_cookie", func(context *gin.Context) {
    context.SetCookie("name", "Shimin Li", -1, "/", "localhost", false, true)
  })
  router.Run(":8080")
}
