关于网站自动登录的问题

[csdnuser2004]

我看了csdn上关于自动登录csdn的例子http://dev.csdn.net/Develop/article/28/28374.shtm。现有问题如下：
1、我建了asp.net中的web应用程序，点击提交后，通过了csdn的验证页面，但跳转时却到了http://localhost/Member/Passport.asp正确的应该为http://www.csdn.net/Member/Passport.asp。不知到谁的自动登录csdn的例子是成功的？
2、自动登录csdn网站的数据提交方式是login_name=aa&password=111111&cookietime=0。

我现在有一个aspx网站页面，用“Visual Sniffer”工具查看它的数据提交格式是：
POST /register.aspx HTTP/1.1
Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */*

请问数据提交这块的格式怎么写？谢谢！！！

学习，我觉的用cookies

？

放在COOKIES里，自动读取的

你把项目传到服务器上应该可以吧。

可能登录认证之后用的是相对路径，所以转到Passport.asp去了。

注意下面的例子中：webRqst.ContentType = "multipart/form-data; boundary=xyz";
所以数据提交部份实际上是从你的boundary也就是
-----------------------------7d42bf2030536开始到结束。
以下是一个例子：

System.Uri uri = new Uri(msp_url);
string dataBoundary = "--xyz";
System.Net.HttpWebRequest webRqst = (System.Net.HttpWebRequest)System.Net.HttpWebRequest.Create(uri);

//add existing cookies to the webrequest.
webRqst.CookieContainer = new CookieContainer();
webRqst.CookieContainer.Add(mspCookies);

//create the WebRequest Content-Body manually for file upload.
webRqst.ContentType = "multipart/form-data; boundary=xyz";
webRqst.Method = "POST";
webRqst.KeepAlive = true;

//get the file content that will be uploaded.
StreamReader sr = new StreamReader(filepath);
string FileData = sr.ReadToEnd(); // test data to send.
sr.Close();

//make a string to store the content.
StringBuilder DataString = new StringBuilder();

DataString.Append(dataBoundary + "\r\n");
DataString.Append("Content-Disposition: form-data; name=\"filename\"\r\n\r\n" + "test.txt\r\n");

DataString.Append(dataBoundary + "\r\n");
DataString.Append("Content-Disposition: form-data; name=" + "\"submitFile\"" +
"; filename=" + "\"" + filename + "\"" + "\r\n");
DataString.Append("Content-Type: text/plain\r\n\r\n");
DataString.Append(FileData);
DataString.Append(dataBoundary + "--\r\n");

byte []Postdata = System.Text.Encoding.Default.GetBytes(DataString.ToString());

//change the requests content length to the size of data being posted in request.
webRqst.ContentLength = Postdata.Length;

//get the response stream from the webrequest and write the data to be posted to the
//Request Stream

Stream tempStream = webRqst.GetRequestStream();
tempStream.Write(Postdata,0,Postdata.Length);
tempStream.Flush();
tempStream.Close();


//change certificate policy to always allow.
System.Net.ServicePointManager.CertificatePolicy = new MyPolicy();
System.Net.HttpWebResponse webRsp = (System.Net.HttpWebResponse)webRqst.GetResponse();

我说了问题的背景是http://dev.csdn.net/Develop/article/28/28374.shtm
不是我的应用程序要实现让用户自动登录；而是我写程序去自动登录别人的网站。不知道其他朋友都理解成什么了？也许是没看http://dev.csdn.net/Develop/article/28/28374.shtm
