Multi_Curl使用身份驗證

Question

我想登錄到一個網站，然後調用大量的URL來獲取源和圖像的刮。它使用普通的捲曲工作正常，但是當我嘗試使用multi_curl時，我得到了完全相同的響應。所以，我只需要登錄一次我正在重新調整curl資源（這可以正常工作），我認爲這可能是它返回相同響應的原因。

有誰知道如何使用multi_curl，但首先認證？

這裏是我使用的代碼：您需要啓用的捲曲度/使用cookies以及

。在文檔上查找它，不要忘記創建具有curl讀寫權限的cookie（空文件）。

 
    $cookie = tempnam ("/tmp", "CURLCOOKIE"); 
    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_URL, $url); 
    curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie);
