爱站程序员基地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 mainimport ("bytes""fmt""mime/multipart""net/http""time")var (CookieName string // cookie kCookieValue string // cookie vTime 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.NameCookieValue = cookie.Valuenowtime := time.Now().Unix()Time = cookie.MaxAge + int(nowtime)}}}// GetCookie 判断cookie过期时间范围cookiefunc 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=
