推荐答案

您需要检查您是否发布所有发布字段..
一些网站使用安全令牌或会话ID来防止bots在他们的网站上登录。
无论如何，你需要安装Live HTTP headers firefox扩展。打开它，并尝试手动登录，然后看到最新实际上被张贴当您按下登录按钮。
。然后添加到第一功能并再次测试

you need to check if you are posting all the "posting fields".. some sites use security tokens or sessions ids to prevent bots from logging on their sites. anyway, you need to install Live HTTP headers firefox extension. open it and try to login manually, then see whats being posted actually when you press login button. after you get the values. add then to the first function and test again.
