我们在爬网时经常会遇到

The remote server returned an error: (407) Proxy Authentication

经过查处最后处理的代码如下：

  HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);                request.Proxy = WebProxy.GetDefaultProxy();                request.Proxy.Credentials = CredentialCache.DefaultCredentials;                HttpWebResponse response = (HttpWebResponse)request.GetResponse();                string responseText = string.Empty;                using (StreamReader sr = new StreamReader(response.GetResponseStream()))                {                    responseText = sr.ReadToEnd();                }                response.Close();                request.Abort();                return responseText;

网上还有其他方法如下：

webRequest = (HttpWebRequest)HttpWebRequest.Create(address); webRequest.Credentials = myCreds; webRequest.PreAuthenticate = true; webRequest.Method = "HEAD"; webRequest.Timeout = 10000; webRequest.AllowWriteStreamBuffering = true;     #region Proxy settings WebProxy proxy = new WebProxy(proxyAddress, proxyPort); proxy.Credentials = new NetworkCredential(cm.FirewallUser, cm.FirewallPassword); webRequest.Proxy = proxy; proxy.Credentials = NetworkCredential("domain\\user", "password") webRequest.Proxy = proxy; webResponse = (HttpWebResponse)webRequest.GetResponse();

我没有测试不知道行不行。
