是否有可能检测/重复使用这些设置吗?
怎么样 ?
我发现了例外的是这是个例外,而连接到http://www.google.com

HttpWebRequest的实际上会默认使用IE代理设置。
如果你不想使用它们,你必须明确覆盖.Proxy proprty为null(无代理),或者你选择的代理设置。
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://news.bbc.co.uk");
//request.Proxy = null; // uncomment this to bypass the default (IE) proxy settings
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Console.WriteLine("Done - press return");
Console.ReadLine();
我得到其中的HttpWebRequest并非默认拿起正确的代理细节非常类似的情况,设置UseDefaultCredentials也不能工作。 强制在代码中设置但是工作一种享受:
IWebProxy proxy = myWebRequest.Proxy;
if (proxy != null) {
string proxyuri = proxy.GetProxy(myWebRequest.RequestUri).ToString;
myWebRequest.UseDefaultCredentials = true;
myWebRequest.Proxy = new WebProxy(proxyuri, false);
myWebRequest.Proxy.Credentials = System.Net.CredentialCache.DefaultCredentials;
}
因为这种使用默认凭据不应该要求他们的详细信息用户。
请注意,这是我的答案贴在这里的一个非常类似的问题的重复: 代理服务器基本身份验证在C#中:HTTP 407错误
另外,具有得到这个播放使用ISA服务器漂亮的问题的人,你可以尝试设置代理的方式如下:
IWebProxy webProxy = WebRequest.DefaultWebProxy;
webProxy.Credentials = CredentialCache.DefaultNetworkCredentials;
myRequest.Proxy = webProxy;
这发生在默认情况下,如果没有明确设置WebRequest.Proxy(默认情况下它被设置为WebRequest.DefaultWebProxy
)。
