Facebook 登录与 PHP curl cookie 错误

Question

我需要一些帮助。

我正在使用curl登录Facebook。在第一次尝试时，它工作正常并且可以正确保存cookie，但是当我重新加载页面时，它显示错误，指出：

抱歉，您的请求无法处理。请重试。

有人可以告诉我如何解决这个问题吗？要么我必须一次又一次地清除cookie文件，要么其他解决方案可以解决此问题。提前谢谢。

$curl = curl_init();

Facebook会在您登录之前严格检查您的用户代理，以防止脚本成为您的脚本。我已经尝试使用所有操作系统和导航器更改我的用户代理，但我从未能够使用我的脚本登录。
