Go语言cookie的基本操作

cookie数据结构介绍

a. Expires，cookie过期时间，使用绝对时间。比如2018/10/10 10:10:10
b. MaxAge，cookie过期时间，使用相对时间，比如300s
c. Secure属性，是否需要安全传输，为true时只有https才会传输该cookie

d. HttpOnly属性，为true时，不能通过js读取该cookie的值

golang读取cookie

a. 读取单个cookie, http.Request.Cookie(key string)

b. 读取所有cookie, http.Request.Cookies()

golang设置cookie

a. cookie := http.Cookie{Name: "username", Value: "astaxie", Expires: expiration}
b. http.SetCookie(w, &cookie)

package main

import (

    "fmt"

    "net/http"

)

func indexHandle(w http.ResponseWriter, r *http.Request) {

    /*cookies := r.Cookies()

    for index, cookie := range cookies {

        fmt.Printf("index:%d cookie:%#v\n", index, cookie)

    }*/

    c, err := r.Cookie("sessionid")

    fmt.Printf("cookie:%#v, err:%v\n", c, err)

    cookie := &http.Cookie{

        Name:   "sessionid",

        Value:  "lkjsdfklsjfklsfdsfdjslf",

        MaxAge: ,

        Domain: "localhost",

        Path:   "/",

    }

    http.SetCookie(w, cookie)

    //在具体数据返回之前设置cookie，否则cookie种不上

    w.Write([]byte("hello"))

}

func main() {

    http.HandleFunc("/", indexHandle)

    http.ListenAndServe(":9090", nil)

}
