用户认证
HttpWebRequest可以实现的啊
最简单的方法，就是把用户名和密码放入url中
比如：http://username:password@www.abc.com/
复杂的办法可以在请求的header里面添加Authorization。格式为：Basic + base64（username:password）
如：
public static string SendDataByGET(string Url, string postDataStr, ref CookieContainer cookie)
{
try
{
string url = Url + (postDataStr == "" ? "" : "?") + postDataStr;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
//if (cookie.Count == 0)
//{
// request.CookieContainer = new CookieContainer();
// cookie = request.CookieContainer;
//}
//else
//{
request.CookieContainer = cookie;
//}
request.KeepAlive = true;
request.Headers.Add("Authorization", "Basic Ym9uc29uOmJvbnNvbg==");
request.CookieContainer = cookie;
request.Credentials = CredentialCache.DefaultCredentials;
request.Method = "GET";
//request.Timeout = 1000 * 300;
request.ContentType = "text/html;charset=gb2312";
request.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; Trident/4.0; MyIE2 0.3; Mogi/1; .NET CLR 2.0.50727; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729)";
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream myResponseStream = response.GetResponseStream();
StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.GetEncoding("gb2312"));
string retString = myStreamReader.ReadToEnd();
myStreamReader.Close();
myResponseStream.Close();
return retString;
}
catch (Exception ex)
{
return "提交出错:" + ex.Message;
}
}
