我正在尝试这样做，所以我可以使用代理和线程登录facebook。我有这个工作单线程与jsoup.connect但它不允许我用多个代理进行多线程。我正在尝试使用HttpsURLConnection登录Facebook。

最初我能够登录，但现在它迫使我更改密码，并发出消息说已检测到异常登录尝试。是否有人能够给我一些指导，告诉我应该在哪些方面实现我的目标。我也尝试使用fiddler登录m.facebook但没有用。我想在没有API的情况下这样做才能看到它是如何工作的。
我正在努力使其适应这一点 - https://www.mkyong.com/java/how-to-automate-login-a-website-java-example/
更新：
所以不仅它显示了不寻常的登录尝试，而且它提供了一个不同的用户代理和ip然后我尝试的那个。登录正在运行，但是当我输入错误的密码时，它没有传递无效用户或电子邮件的字符串。任何人都能解释一下吗？
