c#webBrowser登录问题 [英] c# webBrowser log in problem

问题描述

如果使用此代码打开人脸书

if using this code to open face book

private void button1_Click(object sender, EventArgs e)
{
    webBrowser1.Navigate("www.facebook.com");
    webBrowser1.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBrowser1_DocumentCompleted);
}

并将其用于登录

and using this for log in

        private void button2_Click(object sender, EventArgs e)
        {
            HtmlElement ele = webBrowser1.Document.GetElementById("email"); 
if (ele != null)
                ele.InnerText = "[e-mail]";

            ele = webBrowser1.Document.GetElementById("pass"); 
if (ele != null)
                ele.InnerText = "***********";

            HtmlElement logonForm = webBrowser1.Document.GetElementById("logon-submit"); if (logonForm != null)
                logonForm.InvokeMember("click");
        }

这放置了用户名和密码
但无法实现登录代码.

为什么?

this put the user name and password
but it doesn''t achieve log in code.

why??

推荐答案

从我的评论中发布为解决方案:

由于您尚未完成研究，因此无法正确理解html. input没有内部文本，因为它是一个自闭标签-它具有value属性.您正在做的是糟糕的设计(可能是)-正确查看Facebook API，不要使用像这样的黑登录方法...

希望这会有所帮助，

Posted as a solution from my comment:

Because you haven''t done your research and so don''t understand html properly. An input doesn''t have inner text as it is a self closing tag - it has a value attribute. What you''re doing is poor design (probably) - look at the Facebook API properly and use that not some hacked login method like this...

Hope this helps,
Ed
