我有以下代码,这些代码绕过本地计算机的代理服务器,然后发送一个webrequest。

                System.Net.HttpWebRequest Request;
                System.Net.WebResponse Response;
                System.Net.CredentialCache MyCredentialCache;

//System.Net.WebProxy proxyObject = new WebProxy("http://172.24.1.87:8080",true);

            string strRootURI = "http://172.24.18.240/webdav/";
            string strUserName = "UsName";
            string strPassword = "Pwd";
           // string strDomain = "Domain";
            string strQuery = "";
            byte[] bytes = null;
            System.IO.Stream RequestStream = null;
            System.IO.Stream ResponseStream = null;
            System.Xml.XmlTextReader XmlReader = null;

            try
            {
                // Build the SQL query.
                strQuery = "myWebDavVerb";

                // Create a new CredentialCache object and fill it with the network
                // credentials required to access the server.
                MyCredentialCache = new System.Net.CredentialCache();
                MyCredentialCache.Add(new System.Uri(strRootURI), "Basic", new System.Net.NetworkCredential(strUserName, strPassword));//, strDomain)


                // Create the HttpWebRequest object.
                Request = (System.Net.HttpWebRequest)HttpWebRequest.Create(strRootURI);


                // Add the network credentials to the request.
                Request.Credentials = MyCredentialCache;

                      // Request.Proxy = proxyObject;
                    // Specify the method.
                    Request.Method = "PROPFIND";
    }

Now, while I tried executing I got 403 error. So I checked in the server log and find that the HTTP/1.0 request is coming form an IP 172.24.1.87 而我的IP是 172.24.17.220 .

Is there a way to avoid this? I think this is the root cause of 403 error.

请帮忙。谢谢,

为什么你希望它不使用代理?

Note that you're bypassing requests 到 the local machine, not 从本地机器,如果这是你的困惑点。

EDIT: If you really want to know what's going on, get hold of Wireshark 这会让你看到所有来自你机器的数据包。

If you want to specify "don't use a proxy" then do something like:

request.Proxy = GlobalProxySelection.GetEmptyWebProxy();

HttpWebRequest has a default value for its Proxy Property this is always the result of WebRequest.GetSystemWebProxy() which is the Proxy you configured in IE

if you dont want to use a proxy you need to override the default proxy

Request = (System.Net.HttpWebRequest)HttpWebRequest.Create(strRootURI); 
Request.Proxy = null;
