模拟登陆过程应该很简单,由WebBrowser自动完成(前提myWebBrowser.Navigate参数组成好就行了),难的就是怎么知道获取所有的好友ID,这个很困难,不过可以通过Fiddler抓包很容易就知道了,这里就是一个页面存放者该ID( GetFriends)下所有好友的ID。

自动留言,虽此留言板是通过JS动态生成的,查看源码没有留言文本框以及提交ID,但通过Ie developer toolbar可以看出此文本框是有ID的,而且WebBrowser可以获取由JS动态生成的这些留言本的所有的ID,可以正常的使用HtmlElement获取Document元素,然后执行OnClick事件提交表单。

此方法还有个就是采用了多线程处理循环事件,因为我们提交表单,需要在WebBrowser成功加载完才能执行。



System.Threading.AutoResetEvent obj = new System.Threading.AutoResetEvent(false);

public void btnSubmit_Click(object sender, EventArgs e)

{

obj.Reset();

while (obj.WaitOne(100, false) == false) { Application.DoEvents(); }

//WaitOne 在子程序执行Set才继续执行循环

}

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)

{
obj.Set();
}
