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！

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()] = siteCookies
data, _ := 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()] = siteCookies
data, _ := 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.
