使用PHP和Curl登錄Google，Cookie關閉了嗎？

Question

我有這個代碼用於使用Simple DOM Parser和curl登錄到Google。我試着添加cookiejar文件，但無濟於事。我不斷收到消息：

您瀏覽器的Cookie功能已關閉。請打開它。

關於如何解決這個問題的任何想法？

這裏是我的代碼，以供參考：

$html = file_get_html('https://accounts.google.com/ServiceLogin?hl=en&service=alerts&continue=http://www.google.com/alerts/manage'); 

//... some code for getting post data here 

$curl_connection = curl_init('https://accounts.google.com/ServiceLoginAuth'); 
curl_setopt($curl_connection, CURLOPT_CONNECTTIMEOUT, 30); 
curl_setopt($curl_connection, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)"); 
curl_setopt($curl_connection, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($curl_connection, CURLOPT_SSL_VERIFYPEER, false); 
curl_setopt($curl_connection, CURLOPT_FOLLOWLOCATION, 1); 
curl_setopt($curl_connection, CURLOPT_COOKIEJAR, COOKIEJAR); 
curl_setopt($curl_connection, CURLOPT_COOKIEFILE, COOKIEJAR); 
curl_setopt($curl_connection, CURLOPT_HEADER, true); 
curl_setopt($curl_connection, CURLOPT_RETURNTRANSFER,1); 
curl_setopt($curl_connection, CURLOPT_CONNECTTIMEOUT, 120); 
curl_setopt($curl_connection, CURLOPT_TIMEOUT, 120); 
curl_setopt($curl_connection, CURLOPT_POSTFIELDS, $post_string); 

$result = curl_exec($curl_connection); 
curl_close($curl_connection); 

echo $result; 

Answer 1

下面是一些修改後的代碼工程。

它首先請求登錄頁面獲取初始cookie並提取登錄表單所需的值。接下來，它執行登錄服務的帖子。然後檢查它是否嘗試使用JavaScript和元標記重定向到目標URL。

看起來你已經有了抓取表單字段的代碼，所以我沒有發佈我的，但如果你需要它，讓我知道。只要確保$formFields是一個關聯數組，鍵是字段名稱，值是字段值。
