使用.Net WebRequest Factory

Question

正如理查德威利斯在http://blog.salamandersoft.co.uk/index.php/2009/10/how-to-mock-httpwebrequest-when-unit-testing/中建议我试图调用网络请求行为.

为此(我问我是否在这里乱搞一些东西)我实现了一个IWebRequestCreate并扩展了WebRequest和WebResponse.(链接代码中的更多细节)

但现在在我的代码中,我有一个test(WebRequest.RegisterPrefix)前缀的测试:

[Test]
public void Test() {
     var some = File.ReadAllBytes(@"TestData\WebService\admrond_13jan2011_14jan2011.xml");
     WebRequest.RegisterPrefix("mockPrefix", new WebRequestCreateMock());
     WebRequestFake request = WebRequestCreateMock.CreateRequestFake(some);

     _remoteRepository.PopulateWithMeterData(_meter);
     ... (error in line before)

然后,我收到了这个错误: Invalid URI: The hostname could not be parsed.

但为什么？在我的PopulateWithMeterData(Meter meter)我有这样的电话:

     WebRequest request = WebRequest.Create(urlListMeteringData);
     WebResponse ws = request.GetResponse();

一些建议？我的班级实施有趣吗？

编辑:@Matthew问:

public class WebRequestCreateMock : IWebRequestCreate {

    static WebRequest _nextRequest;
    static readonly object LockObject = new object();

    static public WebRequest NextRequest {
        get { return _nextRequest; }
        set {
            lock (LockObject) {
                _nextRequest = value;
            }
        }
    }

    public WebRequest Create(Uri uri) {
        return _nextRequest;
    }

    public static WebRequestFake CreateRequestFake(byte[] xmlStream) {
        WebRequestFake webRequestFake = new WebRequestFake(xmlStream);
        NextRequest = webRequestFake;
        return webRequestFake;
    }

}

public class WebRequestFake : WebRequest {
    MemoryStream requestStream = new MemoryStream();
    MemoryStream responseStream;

    public override string Method { get; set; }
    public override string ContentType { get; set; }
    public override long ContentLength { get; set; }

    public WebRequestFake(byte[] response) {
        responseStream = new MemoryStream(response);
    }

    public override Stream GetRequestStream() {
        return requestStream;
    }

    public override WebResponse GetResponse() {
        return new WebReponseFake(responseStream);
    }
}

public class WebReponseFake : WebResponse {

    private readonly Stream _responseStream;

    public WebReponseFake(Stream responseStream) {
        _responseStream = responseStream;
    }

    public override Stream GetResponseStream() {
        return _responseStream;
    }
}

而Url就是这样的: mockPrefix://NoMatterUrl

Answer 1

由于错误是“无效的 URI：无法解析主机名”。你可能搞砸了你的 Uri“mockPrefix://NoMatterUrl”

我曾经遇到过这个问题，因为我忘记在域uri和请求参数之间添加“/”。

你能准确地发布你的“NoMatterUri”是什么样子吗？
