用戶認證

HttpWebRequest可以實現的啊

最簡單的方法，就是把用戶名和密碼放入url中

比如：http://username:password@www.abc.com/

復雜的辦法可以在請求的header里面添加Authorization。格式為：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 "提交出錯:" + ex.Message;
??????????? }
??????? }
