使用Post进行WebRequest登录 [英] WebRequest login using Post

问题描述

所以我试图学习如何使用HttpWebRequst访问网页，并且试图将登录凭据发送到该站点.

So i'm trying to learn how to access web pages using HttpWebRequst, and I'm trying to send login credentials to the site.

我在Google上四处搜寻，发现了一些有关使用request.Method ="post";但是我从那儿什么都没有.

I googled around and found something about using request.Method="post"; but i got no where from there.

 

我知道它与网站源代码中的这一部分有关:

I know it has soemthing to do with this part in the web site source code:

< form action ="/" method ="post">
<标签>< span> Benutzername:</span><输入类=文本"名称="b" /></label>
<标签><跨度>密码:</span><输入类别=文本" type ="password"名称="p" /></label>
<输入类型＝隐藏的".名称="r"值=" />
< input class =提交"； type ="submit" value ="Anmelden"； />
</form>

<form action="/" method="post">
<label><span>Benutzername:</span><input class="text" name="b" /></label>
<label><span>Passwort:</span><input class="text" type="password" name="p" /></label>
<input type="hidden" name="r" value="" />
<input class="submit" type="submit"  value="Anmelden" />
</form>

 

这是我尝试的代码:

      user = use.Text;
      passs = pass.Text;
      string useVal;
      string pasVal;
      Encoding encode = Encoding.ASCII;
      useVal = "&class=text&name=" + user;
      useVal += "&class=text&type=password&name=" + passs;
      useVal += "&type=hidden&name=r&value=";

      byte[] data = encode.GetBytes(useVal);

      HttpWebRequest req = (HttpWebRequest)WebRequest.Create("https://endoftheinter.net/");
      req.Credentials = new NetworkCredential(user, passs);
      req.Method = "post";
      req.ContentType = "application/x-www-form-urlencoded";
      req.ContentLength = data.Length;
      Stream stre = req.GetRequestStream();
      stre.Write(data, 0, data.Length);
      stre.Close();

      HttpWebResponse res = (HttpWebResponse)req.GetResponse();

      CookieCollection cookie = res.Cookies;

      Stream recStream = res.GetResponseStream();
      
      StreamReader read = new StreamReader(recStream, encode);
      string strResponse = read.ReadToEnd();

      txt.Text = strResponse;
      read.Close();
      res.Close();

推荐答案

您是否检查过是否确实发布了网站所需的所有参数?

Did you check that you realy POSTed all the parameters that the website needs?

要获取该信息，请使用Microsoft的提琴手:

In order to have that information use Microsoft's fiddler:

使用此Web调试器，您将能够查看发送到服务器的所有部件.

With this web debugger you'll be able to see all the parts that were sent to the server.
