使用.Net WebRequest工廠

正如Richard Willis在http://blog.salamandersoft.co.uk/index.php/2009/10/how-to-mock-httpwebrequest-when-unit-testing/中建議的那樣，我試圖調用一個Web請求來喚起行爲。爲此（我問我是否在這裏搞點東西）我實現了IWebRequestCreate並擴展了WebRequest和WebResponse。（更多鏈接代碼的詳細信息）使用.Net WebRequest工廠

但現在在我的代碼我有一個測試寄存器（WebRequest.RegisterPrefix）的前綴：

[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)

然後，我得到這個錯誤：Invalid URI: The hostname could not be parsed.

但是，爲什麼？在我PopulateWithMeterData(Meter meter)我有這樣的電話：

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

一些建議嗎？在我的課程實施過程中有趣嗎？

編輯：爲@Matthew問：

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; 
    } 
}

和URL是一樣的東西：mockPrefix://NoMatterUrl

我會更充實你的代碼，並舉例說明你用來創建請求的URL。 – 2011-02-17 19:51:26

@Custodio我想使用rtmp鏈接將它傳遞給HTTPHanlder以獲取vlc插件視頻目標源。你能幫助我如何使用你的代碼在閱讀直播流到vlc插件播放器[我的問題在這裏]（http://stackoverflow.com/questions/21862260/http-handler-returns-target-source-for-vlc-plugin -player） – ZahidKakar 2014-02-21 07:14:18

由於錯誤是「無效的URI：無法解析主機名。」你可能搞砸了你的Uri「mockPrefix：// NoMatterUrl」

我曾經遇到這個問題，因爲我忘了在域uri和請求參數之間添加「/」。

你能準確地發佈你的「NoMatterUri」嗎？

您需要使用一個冒號（ '：'）註冊您的前綴;如：

WebRequest.RegisterPrefix("mockPrefix:", new WebRequestCreateMock());

好的！我也試過冒號。不工作:( – Custodio 2011-02-17 20:39:13

我發現有必要在前綴中包含尾隨「/」。例如，「test://localhost/」：

[TestClass] 
public class WebRequestTests 
{ 
    [TestMethod] 
    public void TestWebRequestCreate() 
    { 
     const string uriString = "test://localhost/foo/bar.baz?a=b&c=d"; 
     var webRequest = new MockWebRequestCreateAssertUrl(uriString); 
     Assert.IsTrue(WebRequest.RegisterPrefix("test://localhost/", webRequest), 
         "Failed to register prefix"); 
     Assert.IsNotNull(WebRequest.Create(uriString)); 
    } 

    public class MockWebRequestCreateAssertUrl : IWebRequestCreate 
    { 
     private readonly Uri _expectedUri; 

     public MockWebRequestCreateAssertUrl(string uriString) 
     { 
      _expectedUri = new Uri(uriString); 
     } 

     public WebRequest Create(Uri uri) 
     { 
      Assert.AreEqual(_expectedUri, uri, "uri parameter is wrong"); 
      return new MockWebRequestAssertUrl(); 
     } 
    } 

    public class MockWebRequestAssertUrl : WebRequest {} 
}
