嗯,直接看代碼:

CookieContainer cc=new CookieContainer();
string url = “http://mailbeta.263.net/xmweb”;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Method = “POST”;
request.ContentType = “application/x-www-form-urlencoded”;
request.CookieContainer=cc;
string user=”user”; //使用者名稱
string pass=”pass”; //密碼
string data = “func=login&usr=” + HttpUtility.UrlEncode(user) +“&sel_domain=263.net&domain=263.net&pass=” +HttpUtility.UrlEncode(pass) +“&image2.x=0&image2.y=0&verifypcookie=&verifypip=”;
request.ContentLength = data.Length;
StreamWriter writer = new StreamWriter(request.GetRequestStream(),Encoding.ASCII);
writer.Write(data);
writer.Flush();
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
string encoding = response.ContentEncoding;
if (encoding == null || encoding.Length < 1) {
    encoding = "UTF-8"; //預設編碼
}
StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding(encoding));
data = reader.ReadToEnd();
Console.WriteLine(data);
response.Close();

int index=data.IndexOf("sid=");
string sid=data.Substring(index+4,data.IndexOf("&",index)-index-4);
Console.WriteLine(sid);

url ="http://wm11.263.net/xmweb?func=mlst&act=show&usr="+user+"&sid="+sid+"&fid=1&desc=1&pg=1&searchword=&searchtype=&searchsub=&searchfd=&sort=4";
request = (HttpWebRequest)WebRequest.Create(url);
request.CookieContainer = cc;
foreach(Cookie cookie in response.Cookies) {
    cc.Add(cookie);
}
response = (HttpWebResponse)request.GetResponse();
encoding = response.ContentEncoding;
if (encoding == null || encoding.Length < 1) {
    encoding = "UTF-8"; //預設編碼
}
reader = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding(encoding));
data = reader.ReadToEnd();
Console.WriteLine(data);
response.Close();

這段代碼的意思是,類比登陸263郵箱,別列出收件匣內容(html代碼)
