How can make a Curl Store Cookie in Golang?
问题
我想发送一个POST/GET请求，并且可以将cookie存储在程序附近的一个文件中。
以下是一个示例的PHP代码：
$___path = "";function send($url, $fields = array(), $reffer = false, $get = false){global $___path;$cookie_file_path = $___path . "cookie.txt"; // 存储cookie的文件路径$agent = "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:40.0) Gecko/20100101 Firefox/40.1";$ch = curl_init();$headers[] = "Accept: */*";$headers[] = "Connection: Keep-Alive";curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);curl_setopt($ch, CURLOPT_HEADER, 0);curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);if ($reffer == false) {} else {curl_setopt($ch, CURLOPT_REFERER, $reffer);}curl_setopt($ch, CURLOPT_USERAGENT, $agent);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file_path);curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file_path);curl_setopt($ch, CURLOPT_URL, $url);if ($get) {curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");} else {curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");curl_setopt($ch, CURLOPT_POST, 1);if (count($fields) >= 1) {$POSTFIELDS = http_build_query($fields);curl_setopt($ch, CURLOPT_POSTFIELDS, $POSTFIELDS);}}$result = curl_exec($ch);return $result;}
这段代码可以帮助你使用cookie jar存储。
关于Go语言的示例，你可以参考net/http包中的CookieJar文档：https://golang.org/pkg/net/http/#CookieJar
希望对你有帮助！

I want send a post/get request and can store cookies in a file near on Program.
Sample Php Code:
$___path="";function send($url,$fields=array(),$reffer=false,$get=false){global $___path;$cookie_file_path = $___path."cookie.txt";//this file of cookies.$agent = "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:40.0) Gecko/20100101 Firefox/40.1";$ch = curl_init();$headers[] = "Accept: */*";$headers[] = "Connection: Keep-Alive";curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);curl_setopt($ch, CURLOPT_HEADER, 0);curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);if($reffer == false){}else{curl_setopt($ch,CURLOPT_REFERER,$reffer);}curl_setopt($ch, CURLOPT_USERAGENT, $agent);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file_path);curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file_path);curl_setopt($ch, CURLOPT_URL, $url);if($get){curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");}else{curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");curl_setopt($ch, CURLOPT_POST, 1);if(count($fields) >= 1){$POSTFIELDS = http_build_query($fields);curl_setopt($ch, CURLOPT_POSTFIELDS, $POSTFIELDS);}}$result = curl_exec($ch);return $result;}
may help me to work with cookie jar store?
this not have a sample : https://github.com/juju/persistent-cookiejar
may a person write a sample about https://golang.org/pkg/net/http/#CookieJar ?

你不需要将 cookies 保存到文件中，只需保持你的 Go 进程运行即可。如果你真的想要保存到文件中，可以按照以下步骤进行操作：
import "net/http/cookiejar"import "net/http"import "encoding/json"import "io/ioutil"cookies := make(map[string][]*http.Cookie)jar, _ := cookiejar.New(nil)client := http.Client{Jar: jar}r, _ := client.Get(/* 做你需要的操作 */)siteCookies := jar.Cookies(r.Request.URL)cookies[r.Request.URL.String()] = siteCookiesdata, _ := json.Marshal(cookies)ioutil.WriteFile("/path/to/cookies.txt", data, 0644)
然后在启动时，你可以读取该文件，对于每个键调用 url.Parse，然后使用它调用 jar.SetCookies。

英文:
You don't need to save cookies to a file, just keep your go process running. If you really wanted to, you would do something like:
import "net/http/cookiejar"import "net/http"import "encoding/json"import "io/ioutil"cookies := make(map[string][]*http.Cookie)jar, _ := cookiejar.New(nil)client := http.Client{Jar: jar}r, _ := client.Get(/* do whatever */)siteCookies := jar.Cookies(r.Request.URL)cookies[r.Request.URL.String()] = siteCookiesdata, _ := json.Marshal(cookies)ioutil.WriteFile("/path/to/cookies.txt", data, 0644)
And then when you start, you would read that file, for each key call url.Parse, and then use that to call jar.SetCookies.
