关于HttpWebRequest的问题

[bupo_007]

我想写一个登陆学校图书馆的程序获，取借阅信息
登陆图书馆需要用户名和密码
string url2 = "http://59.64.144.2/reader/infoList.jsp";//登陆页面的连接
怎么用密码和用户名参数登陆呢
myHttpWebRequest.ContentType = "application/x-www-form-urlencoded";
这句中是什么意思

[珍惜生命远离CPP]

myHttpWebRequest.ContentType = "application/x-www-form-urlencoded";
URL编码，也就是你提交的数据内容编码

你需要使用POST的方式提交你的用户名密码。

string url = "http://59.64.144.2/reader/login.jsp?str_kind=login";
string url2 = "http://59.64.144.2/reader/infoList.jsp";


string indata = "barcode=" + user + "&password=" + psw;
string outdata = "";//return string


CookieContainer myCookieContainer = new CookieContainer();
//新建一个CookieContainer来存放Cookie集合

HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create(url);
//新建一个HttpWebRequest

myHttpWebRequest.ContentType = "application/x-www-form-urlencoded";
myHttpWebRequest.ContentLength = indata.Length;
myHttpWebRequest.Method = "POST";
myHttpWebRequest.CookieContainer = myCookieContainer;
//设置HttpWebRequest的CookieContainer为刚才建立的那个myCookieContainer

Stream myRequestStream = myHttpWebRequest.GetRequestStream();
StreamWriter myStreamWriter = new StreamWriter(myRequestStream, Encoding.GetEncoding("gb2312"));
myStreamWriter.Write(indata);
//把数据写入HttpWebRequest的Request流

myStreamWriter.Close();
myRequestStream.Close();
//关闭打开对象

HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();
//新建一个HttpWebResponse

myHttpWebResponse.Cookies = myCookieContainer.GetCookies(myHttpWebRequest.RequestUri);
//获取一个包含url的Cookie集合的CookieCollection

Stream myResponseStream = myHttpWebResponse.GetResponseStream();
//StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.GetEncoding("gb2312"));
StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.Default);
outdata = myStreamReader.ReadToEnd();
//把数据从HttpWebResponse的Response流中读出

myStreamReader.Close();
myResponseStream.Close();
//显示"登录"

//拿到了Cookie，再进行请求就能直接读取到登录后的内容了
myHttpWebRequest = (HttpWebRequest)WebRequest.Create(url2);
myHttpWebRequest.CookieContainer = myCookieContainer;//*
//刚才那个CookieContainer已经存有了Cookie,把它附加到HttpWebRequest中则能直接通过验证

myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();
myHttpWebResponse.Cookies = myCookieContainer.GetCookies(myHttpWebRequest.RequestUri);
myResponseStream = myHttpWebResponse.GetResponseStream();
//myStreamReader = new StreamReader(myResponseStream, Encoding.GetEncoding("gb2312"));
myStreamReader = new StreamReader(myResponseStream, Encoding.Default);
outdata = myStreamReader.ReadToEnd();
myStreamReader.Close();
myResponseStream.Close();
//Console.WriteLine(outdata);

return outdata;
}
这是别人写的代码，其中
string indata = "barcode=" + user + "&password=" + psw;
barcode和&passwords是怎么来的呢？
