guzzle 爬取数据， 302 后怎么获取 sessionid

This topic created in 1980 days ago, the information mentioned may be changed or developed.

         $response = $client->request('GET', self::$jumpUrl, [
                'cookies' => $cookieJar,
                'query' => [
                    'tochannelid' => $channelId
                ],
                'allow_redirects' => [
                    'max' => 5,        // allow at most 10 redirects.
                    'track_redirects' => true
                ],
                'debug' => true
            ]);
            $lastRedirectArr = $response->getHeaders()['X-Guzzle-Redirect-History'];
            list($code, $msg) = $this->getCookie($lastRedirectArr[1]);
            
            $client = new Client();
            $res = $client->request('GET', $url);
            $header = $res->getHeaders();

通过主账号登录跳转获取子账号的 cookie,实现子账号登录。

现在问题是通过主账号，获取不到 302 后的 cookie

打开 debug,是存在正确 cookie 的我获取最后的跳转链接，然后再次请求，获取到的 cookie 是错误的。

现在不知道问题哪里

获取

getheaders

client-

多次重定向？
找个能获取的点进行存储起来用

guzzle 自身的重定向功能好像不支持携带 cookie，需要手动来进行 redirect 跳转。
1.关闭 allow_redirects (关闭字段重定向)
2.判断$response 是否是 302
3.如果是重定向
4.则请求这个回调函数

```
public function callback($redirect, $cookie)
{
$client = new Client();
$response = $client->request('GET', $redirect, [
'headers' => [
'Cookie' => $cookie,
],
'allow_redirects' => false
]);
if ($response->getStatusCode() === 302) {
$redirect = $response->getHeaderLine('Location');
$cookie = $response->getHeaderLine('Set-Cookie') ?? $cookie;
if (strpos($redirect, 'http') === false) {
$redirect = self::$adminBaseLink . $redirect;
}
$cookie = $this->callback($redirect, $cookie);
}
$cookie = $response->getHeaderLine('Set-Cookie') ?? $cookie;
return $cookie;
}
```
