【go】 设置cookie的两种方法

package main

import (
    "net/http"
    "io"
)

func main() {
    http.HandleFunc("/", Cookie)
    http.HandleFunc("/cookie1", Cookie1)
    http.ListenAndServe(":8080", nil)
}

func Cookie(w http.ResponseWriter, r *http.Request) {
    ck := &http.Cookie{
        Name:   "myCookie",  //名字
        Value:  "hello",      //值
        Path:   "/",          //路径
        Domain: "localhost", //域名
        MaxAge: 120,          //存活时间
    }

    http.SetCookie(w, ck)  //设置cookie

    ch2, err := r.Cookie("myCookie")
    if err != nil {
        io.WriteString(w, err.Error())
        return
    }
    io.WriteString(w, ch2.Value)
}

/**
  当value为空格时
 */
func Cookie1(w http.ResponseWriter, r *http.Request) {
    ck := &http.Cookie{
        Name:   "myCookie",
        Value:  "hello World",
        Path:   "/",
        Domain: "localhost",
        MaxAge: 120,
    }

    w.Header().Set("set-cookie",ck.String())

    ch2, err := r.Cookie("myCookie")
    if err != nil {
        io.WriteString(w, err.Error())
        return
    }
    io.WriteString(w, ch2.Value)
}
