使用创建的 HttpWebResponse 接口 Returns 401 未授权错误

Question

所以我最初有这个网络请求代码：

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
request.UseDefaultCredentials = true;
WebResponse response = request.GetResponse();

为了添加单元测试，我将其更改为：

IHttpWebRequest request = IHttpWebRequestFactory.Create(uri);
request.UseDefaultCredentials = true;
IWebResponse response = request.GetResponse();

IHttpWebRequest:

public interface IHttpWebRequest
{
    bool UseDefaultCredentials { get; set; }
    IWebResponse GetResponse();
}

MyHttpWebRequest:

public class MyHttpWebRequest : IHttpWebRequest
{
    private readonly HttpWebRequest httpWebRequest;
    private bool useDefaultCredentials;

    public MyHttpWebRequest(HttpWebRequest httpWebRequest)
    {
        this.httpWebRequest = httpWebRequest;
    }

    public bool UseDefaultCredentials
    {
        get { return useDefaultCredentials;  }
        set { useDefaultCredentials = value; }
    }

    public IWebResponse GetResponse()
    {
        return new MyWebResponse((HttpWebResponse)httpWebRequest.GetResponse());
    }
}

IHttpWebRequestFactory:

public interface IHttpWebRequestFactory
{
    IHttpWebRequest Create(string Uri);
}

HttpWebRequestFactory:

public class HttpWebRequestFactory : IHttpWebRequestFactory
{
    public IHttpWebRequest Create(string Uri)
    {
        return new MyHttpWebRequest((HttpWebRequest)WebRequest.Create(Uri));
    }
}

IWebResponse:

public interface IWebResponse
{
    Stream GetResponseStream();
}

我的网络响应：

public class MyWebResponse : IWebResponse
{
    private WebResponse webResponse;

    public MyWebResponse(HttpWebResponse webResponse)
    {
        this.webResponse = webResponse;
    }

    public Stream GetResponseStream()
    {
        return webResponse.GetResponseStream();
    }
}

但是网站现在 returns 出现 HTTP 错误 401 未授权。不过使用 Fiddler 是可行的。我也尝试设置request.Credentials = CredentialCache.DefaultNetworkCredentials、request.PreAuthenticate = true等，但没有用。 :(

我也尝试向 Credentials 提供我的用户名和密码，但未授权的错误仍然出现，这很奇怪，因为上面的原始代码有效。 :(

您没有正确使用 useDefaultCredentials，试试这个：

MyHttpWebRequest:

public class MyHttpWebRequest : IHttpWebRequest
{
    private readonly HttpWebRequest httpWebRequest;

    public MyHttpWebRequest(HttpWebRequest httpWebRequest)
    {
        this.httpWebRequest = httpWebRequest;
    }

    public bool UseDefaultCredentials
    {
        get { return this.httpWebRequest.UseDefaultCredentials;  }
        set { this.httpWebRequest.UseDefaultCredentials = value; }
    }

    public IWebResponse GetResponse()
    {
        return new MyWebResponse((HttpWebResponse)httpWebRequest.GetResponse());
    }
}
