Go語言cookie的基本操作

cookie數據結構介紹

 

cookie數據結構介紹

a. Expires，cookie過期時間，使用絕對時間。比如2018/10/10 10:10:10
b. MaxAge，cookie過期時間，使用相對時間，比如300s
c. Secure屬性，是否需要安全傳輸，為true時只有https才會傳輸該cookie
Go語言cookie的基本操作
d. HttpOnly屬性，為true時，不能通過js讀取該cookie的值

 

golang讀取cookie

a. 讀取單個cookie, http.Request.Cookie(key string)

b. 讀取所有cookie, http.Request.Cookies()

 

golang設置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: 3600,
        Domain: "localhost",
        Path:   "/",
    }

    http.SetCookie(w, cookie)

    //在具體數據返回之前設置cookie，否則cookie種不上
    w.Write([]byte("hello"))
}

func main() {
    http.HandleFunc("/", indexHandle)
    http.ListenAndServe(":9090", nil)
}
