紫色飞猪的研发之旅--03golang：获取cookie

在调用第三方接口时，需要用到凭证，大多数接口使用token即可，那自然有小多数接口使用cookie等认证。此系列将围绕我的研发之旅进行。

获取cookie相对简单独立，直接上代码

package main

import (
"bytes"
"fmt"
"mime/multipart"
"net/http"
"time"
)

var (
CookieName  string // cookie k
CookieValue string // cookie v
Time        int    // cookie 限期
)

// 初始化cookie所需信息
func cookieInit() {
postData := make(map[string]string)
postData["username"] = "axxxn"
postData["password"] = "axxxxxt"
url := "http://txxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxkens"
postWithFormData("POST", url, &postData)

}

// PostWithFormData 获取cookie和过期时间
func postWithFormData(method, url string, postData *map[string]string) {
body := new(bytes.Buffer)
w := multipart.NewWriter(body)
for k, v := range *postData {
w.WriteField(k, v)
}
w.Close()
req, _ := http.NewRequest(method, url, body)
req.Header.Set("Content-Type", w.FormDataContentType())
resp, err := http.DefaultClient.Do(req)
if err != nil || resp.StatusCode > 300 {
fmt.Println("err = ", err)
fmt.Printf("%+v\n", resp.Cookies())
return
}
defer resp.Body.Close()
for _, cookie := range resp.Cookies() {
if cookie.Name == "tke" {
CookieName = cookie.Name
CookieValue = cookie.Value
nowtime := time.Now().Unix()
Time = cookie.MaxAge + int(nowtime)
}
}
}

// GetCookie 判断cookie过期时间范围cookie
func GetCookie() (string, string) {
nowtime := time.Now().Unix()
if len(CookieValue) == 0 {
cookieInit()
} else {
if int(nowtime) >= Time {
cookieInit()
}
}
return CookieName, CookieValue
}

func main()  {
n,v := GetCookie()
fmt.Println("n = ", n)
fmt.Println("v = ", v)
}
// n = hubxxxxxxxen
// v = eyJhbGxxxxx9pZCI6MCwib3Blbl91c2VyX2lkIjowLCJxxxxiLCJhdmF0YXJfdXJsIjoiIiwic3BhY2VfaWQiOiIiLCJhcHBfa2V5xxxfaWQiOiIyZWNiMDkyNi03ZWYzLxxxxN1ZWRfYXQiOjE2MzA0ODxxxxiOIOfC0TJxxAcc=
