我正在尝试使用凭据从客户端站点的
Windows服务向代理服务器进行身份验证,但不断收到以下响应:
StatusCode: 407, ReasonPhrase: ‘Proxy Authentication Required’, Version: 1.1, Content: System.Net.Http.StreamContent, Headers:
{
Pragma: no-cache
Proxy-Connection: close
Connection: close
Cache-Control: no-cache
Proxy-Authenticate: NTLM
Set-Cookie: BCSI-CS-2737f33ff5b5f739=2; Path=/
Content-Length: 1351
Content-Type: text/html; charset=utf-8
}
我的本地代理配置完全不同,我无法重新创建该问题.这是我用来验证服务器的代码. (如代码中所述,它基于:HttpClient and using proxy – constantly getting 407
private HttpClient GenerateHttpClientWithProxySettings()
{
//Code based on https://stackoverflow.com/questions/29856543/httpclient-and-using-proxy-constantly-getting-407
// First create a proxy object
var proxy = new WebProxy()
{
Address = new Uri($"{Settings.ProxyAddress}:{Settings.PortNumber}"),
BypassProxyOnLocal = false,
UseDefaultCredentials = false,
// *** These creds are given to the proxy server, not the web server ***
Credentials = new NetworkCredential(
userName: Settings.ProxyUserName,
password: Settings.ProxyPassword)
};
//Debug:
Settings.log.Debug($"{Settings.ProxyAddress}:{Settings.PortNumber}");
Settings.log.Debug(Settings.ProxyUserName);
Settings.log.Debug(Settings.ProxyPassword);
// Now create a client handler which uses that proxy
var httpClientHandler = new HttpClientHandler()
{
Proxy = proxy,
UseProxy = true,
AllowAutoRedirect = true,
};
//// Omit this part if you don't need to authenticate with the web server:
//if (needServerAuthentication)
//{
// httpClientHandler.PreAuthenticate = true;
// httpClientHandler.UseDefaultCredentials = false;
// // *** These creds are given to the web server, not the proxy server ***
// httpClientHandler.Credentials = new NetworkCredential(
// userName: serverUserName,
// password: serverPassword);
//}
// Finally, create the HTTP client object
HttpClient client = new HttpClient(handler: httpClientHandler, disposeHandler: true);
return client;
}
//Get
private async Task<ReturnedData> GetRequestWithProxy(string url)
{
ReturnedData result = new ReturnedData();
using (HttpClient client = GenerateHttpClientWithProxySettings())
{
using (HttpResponseMessage message = await client.GetAsync(url))
{
Settings.log.Debug("[[message:]]");
Settings.log.Debug(message.ToString());
result.StatusCode = message.StatusCode.ToString();
result.Succceded = message.IsSuccessStatusCode;
using (HttpContent content = message.Content)
{
Settings.log.Debug("[[content:]]");
Settings.log.Debug(content.ToString());
result.Content = await message.Content.ReadAsStringAsync();
return result;
}
}
}
}
// Post
private async Task<ReturnedData> PostRequestWithProxy(string url, dynamic payload)
{
ReturnedData result = new ReturnedData();
string stringPayload = await Task.Run(() => JsonConvert.SerializeObject(payload));
// Wrap our JSON inside a StringContent which then can be used by the HttpClient class
using (var httpContent = new StringContent(stringPayload, Encoding.UTF8, "application/json"))
{
using (HttpClient client = GenerateHttpClientWithProxySettings())
{
using (HttpResponseMessage message = await client.PostAsync(url, httpContent))
{
Settings.log.Debug(message.ToString());
result.StatusCode = message.StatusCode.ToString();
result.Succceded = message.IsSuccessStatusCode;
using (HttpContent content = message.Content)
{
Settings.log.Debug(content.ToString());
result.Content = await message.Content.ReadAsStringAsync();
return result;
}
}
}
}
}
任何有关我在这里做错的帮助将不胜感激.
谢谢!
最佳答案 从响应标题
Proxy-Authenticate: NTLM
代理接受Windows凭据而不是用户名/密码.
试试这个
var proxy = new WebProxy()
{
...
UseDefaultCredentials = true
/*Credentials = new NetworkCredential(
userName: Settings.ProxyUserName,
password: Settings.ProxyPassword)*/
};
