HttpWebResponse 远程服务器返回错误: (403) 已禁止

 前几天以下代码有个小问题：

GET形势获取URL的返回值出现对访问同一URL过于频繁就会出现403已禁止 

1    string result = "";
2    HttpWebRequest httpRequest = (HttpWebRequest)HttpWebRequest.Create(strUrl);            
3    HttpWebResponse respone = (HttpWebResponse)httpRequest.GetResponse();
4    StreamReader stream = new StreamReader(respone.GetResponseStream(), Encoding.UTF8);
5    result = stream.ReadToEnd();

解决方案加个获取身份验证信息

1  string result = "";
2  HttpWebRequest httpRequest = (HttpWebRequest)HttpWebRequest.Create(strUrl);
3  httpRequest.Timeout = 10000;
4  httpRequest.UserAgent = "Code Sample Web Client";
5  httpRequest.Credentials = CredentialCache.DefaultCredentials;
6  HttpWebResponse respone = (HttpWebResponse)httpRequest.GetResponse();
7  StreamReader stream = new StreamReader(respone.GetResponseStream(), Encoding.UTF8);
8  result = stream.ReadToEnd();
