Question

我正在尝试创建一个使用.NET Framework消费RSS数据的应用程序。 RSS站点需要用户名和密码才能开始。并且我在我的工作场所运行此应用程序，这需要NTLM身份验证才能连接到互联网。

以下是我尝试使用的代码

NetworkCredential nc = new NetworkCredential("SITEUSERNAME", "SITEPASSWORD");
CredentialCache cache = new CredentialCache();
cache.Add(new Uri(RSSFeed), "Basic", nc);
cache.Add(new Uri(RSSFeed), "Ntlm", new NetworkCredential("USERNAME","PASSWORD","DOAMIN"));
HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create(RSSFeed);
myHttpWebRequest.Proxy.Credentials = cache;
HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();

我得到407错误，如果我只是使用CredentialCache.DefaultNetworkCredentials，我得到401错误。

Answer 1

使用以下代码

解决了这个问题

 string credentials = Convert.ToBase64String(ASCIIEncoding.ASCII.GetBytes("UserName" + ":" + "Password"));
 StringBuilder outputData = new StringBuilder();
 HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create(RSSFeed);
 myHttpWebRequest.Proxy.Credentials = CredentialCache.DefaultNetworkCredentials;
 myHttpWebRequest.Headers.Add("Authorization", "Basic " + credentials);
 HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();
 Stream streamResponse = myHttpWebResponse.GetResponseStream();

Answer 2

如果此代码有效，那么上面的原始代码是错误的。你应该设置

request.Proxy.Credentials = CredentialCache.DefaultNetworkCredentials;

和

NetworkCredential nc = new NetworkCredential("SITEUSERNAME", "SITEPASSWORD");
CredentialCache cache = new CredentialCache();
cache.Add(new Uri(RSSFeed), "Basic", nc);
cache.Add(new Uri(RSSFeed), "Ntlm", new NetworkCredential("USERNAME","PASSWORD","DOAMIN"));
HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create(RSSFeed);
myHttpWebRequest.Credentials = cache;

换句话说，您已经交换了代理和目标服务器的凭据。

网络使用HttpWebRequest进行身份验证和网站身份验证
