嘲笑的Htt prequest失去查询字符串 [英] Mocked HttpRequest loses the QueryString

问题描述

我需要测试其管理复杂的查询字符串的辅助类。

我用这个helper方法嘲笑的HttpContext ：

 公共静态的HttpContext FakeHttpContext（URL字符串，字符串的queryString）
{
    VAR HTT prequest =新的Htt prequest（，URL的queryString）;
    VAR的StringWriter =新的StringWriter（）;
    VAR HTT presponse =新的Htt presponse（StringWriter的）;
    VAR的HttpContext =新的HttpContext（HTT prequest，HTT presponse）;    VAR sessionContainer =新HttpSessionStateContainer（ID，新SessionStateItemCollection（）
                                            新HttpStaticObjectsCollection（），10，真实，
                                            HttpCookieMode.AutoDetect，
                                            SessionStateMode.InProc，FALSE）;
    SessionStateUtility.AddHttpSessionStateToContext（HttpContext的，sessionContainer）;    返回HttpContext的;
}
 

问题是，的Htt prequest 失去查询字符串：

  HttpContext.Current = MockHelpers.FakeHttpContext（http://www.google.com/，NAME = gdfgd）;
 

HttpContext.Current.Request.Url 是http://www.google.com/和没有http://www.google.com/?name=gdfgd预期。

如果我调试我看到刚过型Htt prequest constrctor查询字符串将丢失。

我使用的解决方法是通过URL以查询字符串的Htt的prequest构造：

  HttpContext.Current = MockHelpers.FakeHttpContext（http://www.google.com/?name=gdfgd，）;
 

解决方案

感谢<一个href=\"http://stackoverflow.com/questions/19704059/mocked-htt$p$pquest-loses-the-querystring#comment29273240_19704059\">Halvard's评论我有线索找到了答案：

<一个href=\"http://msdn.microsoft.com/en-us/library/system.web.htt$p$pquest.htt$p$pquest%28v=vs.110%29.aspx\"相对=nofollow> 在它们中间断开的Htt prequest构造函数的参数。

该URL参数用于创建的Htt prequest.Url 和查询字符串用于的Htt prequest.QueryString 属性：他们被分离

要具有一致的Htt prequest与查询字符串你有一个网址：

  VAR HTT prequest =新的Htt prequest
      （，http://www.google.com/?name=gdfgd，名称= gdfgd）;
 

否则，你将有URL或QueryString属性不正确。

还有就是我更新的模拟助手的方法：

 公共静态的HttpContext FakeHttpContext（字符串URL）
{
    VAR URI =新的URI（URL）;
    VAR HTT prequest =新的Htt prequest（的String.Empty，uri.ToString（），uri.Query.TrimStart（）'？'）;
    VAR的StringWriter =新的StringWriter（）;
    VAR HTT presponse =新的Htt presponse（StringWriter的）;
    VAR的HttpContext =新的HttpContext（HTT prequest，HTT presponse）;    VAR sessionContainer =新HttpSessionStateContainer（ID，新SessionStateItemCollection（）
                                            新HttpStaticObjectsCollection（），10，真实，
                                            HttpCookieMode.AutoDetect，
                                            SessionStateMode.InProc，FALSE）;
    SessionStateUtility.AddHttpSessionStateToContext（HttpContext的，sessionContainer）;    返回HttpContext的;
}
 

I need to test an helper class which manage complex querystring.

I use this helper method to mock the HttpContext:

public static HttpContext FakeHttpContext(string url, string queryString)
{
    var httpRequest = new HttpRequest("", url, queryString);
    var stringWriter = new StringWriter();
    var httpResponse = new HttpResponse(stringWriter);
    var httpContext = new HttpContext(httpRequest, httpResponse);

    var sessionContainer = new HttpSessionStateContainer("id", new SessionStateItemCollection(),
                                            new HttpStaticObjectsCollection(), 10, true,
                                            HttpCookieMode.AutoDetect,
                                            SessionStateMode.InProc, false);
    SessionStateUtility.AddHttpSessionStateToContext(httpContext, sessionContainer);

    return httpContext;
}

The problem is that the HttpRequest loses the querystring:

HttpContext.Current = MockHelpers.FakeHttpContext("http://www.google.com/", "name=gdfgd");

HttpContext.Current.Request.Url is "http://www.google.com/" and not "http://www.google.com/?name=gdfgd"as expected.

If I debug I see that just after the HttpRequest constrctor the querystring is lost.

The workaround I'm using is to pass the url with querystring to the HttpRequest constructor:

HttpContext.Current = MockHelpers.FakeHttpContext("http://www.google.com/?name=gdfgd","");

解决方案

Thanks to Halvard's comment I had the clue to find the answer:

HttpRequest constructor parameters are disconnected between them.

The url parameter is used to create the HttpRequest.Url and the queryString is used for HttpRequest.QueryString property: they are detached

To have a consistent HttpRequest with an url with querystring you have to:

var httpRequest = new HttpRequest
      ("", "http://www.google.com/?name=gdfgd", "name=gdfgd");

Otherwise you'll have either the Url or the QueryString property not correctly loaded.

There is my updated Mock Helpers method:

public static HttpContext FakeHttpContext(string url)
{
    var uri = new Uri(url);
    var httpRequest = new HttpRequest(string.Empty, uri.ToString(), uri.Query.TrimStart('?'));
    var stringWriter = new StringWriter();
    var httpResponse = new HttpResponse(stringWriter);
    var httpContext = new HttpContext(httpRequest, httpResponse);

    var sessionContainer = new HttpSessionStateContainer("id", new SessionStateItemCollection(),
                                            new HttpStaticObjectsCollection(), 10, true,
                                            HttpCookieMode.AutoDetect,
                                            SessionStateMode.InProc, false);
    SessionStateUtility.AddHttpSessionStateToContext(httpContext, sessionContainer);

    return httpContext;
}
