[英]Facebook Login using cURL and PHP
我正在嘗試使用curl訪問Facebook登錄頁面。 我的意圖是登錄到Facebook,然后執行一些操作。 由於最新的限制,我沒有使用facebook API。我需要在帖子上留言,而僅使用API是不可能的。
這是我的一些代碼:
curl_setopt($ch, CURLOPT_URL,"https://web.facebook.com");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
$response = curl_exec($ch);
curl_close($ch);
echo $response;
我希望它重定向到登錄頁面,然后在用戶填寫登錄表單時,我將獲取憑據並將其用於重定向到首頁並開始抓取。
無論如何,這就是我得到的:
(PS,我是程序的作者), 該程序登錄到Facebook以發送消息。 登錄代碼可在此處找到,登錄過程在構造函數中完成,
但要點是,您需要先執行GET請求以獲取cookie和csrf令牌以及其他內容,然后從lgoin形式中解析出該內容,然后將其發布回application/x-www-form-urlencoded
POST請求以及用戶名和密碼,以特定於您的cookie會話的登錄URL,您還必須從第一個GET請求中收到的html中解析出該URL。
使用用戶代理暗示您擁有糟糕的javascript支持(因為實際上,對於PHP,您根本沒有),這也是您的最大利益。該代碼使用的示例是'Mozilla/5.0 (BlackBerry; U; BlackBerry 9300; en) AppleWebKit/534.8+ (KHTML, like Gecko) Version/6.0.0.570 Mobile Safari/534.8+'

"//a[contains(@href,'/login/save-device/cancel/')]"
和protip來檢測該問題確認您已成功登錄,是要查找注銷按鈕,該按鈕在XPath中看起來像//a[contains(@href,"/logout.php")]
該代碼最相關的部分是:
