Question

我正在尝试将网页作为流返回。

当我尝试访问外部网址即“http://www.google.com”时，我到目前为止的工作情况。但是，当我尝试访问我们服务器上的网站时，即“http://servername/applicationname/default.aspx”。

以下是我目前拥有的代码，适用于外部代码：

Dim request As HttpWebRequest = CType(WebRequest.Create("http://www.google.com/search?q=google"), HttpWebRequest)
Dim response As HttpWebResponse = CType(request.GetResponse, HttpWebResponse)
Dim resStream As Stream = response.GetResponseStream

但是当我用这条线尝试时，我得到The remote server returned an error: (401) Unauthorized.

Dim request As HttpWebRequest = CType(WebRequest.Create("http://Server/Application/SubFolder/testing.aspx"), HttpWebRequest)        
Dim response As HttpWebResponse = CType(request.GetResponse(), HttpWebResponse)

我尝试使用以下方法更改它访问服务器的凭据：

request.Credentials = CredentialCache.DefaultCredentials

我尝试过使用网络客户端：

Dim myWebClient As New WebClient()
Dim myStream As Stream = myWebClient.OpenRead("http://Server/Application/SubFolder/testing.aspx")

Answer 1

您收到401错误，因为网络服务器的身份验证拒绝了该请求。您可能需要明确设置凭据。

            request.Credentials = New NetworkCredential("userName", "password", "domain")

GetResponse不适用于内部网址
