如何在FakeHttpContext中设置Request.Header以进行单元测试 [英] How to setup Request.Header in FakeHttpContext for Unit Testing

问题描述

我有一个 FakeHttpContext ，我一直在尝试修改以包含一些标头以进行测试

I have a FakeHttpContext I have been trying to modify to include some headers for testing purposes

public static HttpContext FakeHttpContext()
{
    var httpRequest = new HttpRequest("", "http://stackoverflow/", "");
    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);

    httpContext.Items["AspSession"] = typeof(HttpSessionState).GetConstructor(
                                        BindingFlags.NonPublic | BindingFlags.Instance,
                                        null, CallingConventions.Standard,
                                        new[] { typeof(HttpSessionStateContainer) },
                                        null)
                                .Invoke(new object[] { sessionContainer });

    return httpContext;
 }

这在没有标题的情况下有效，但是当我在 httpRequest 和 stringWriter 行之间添加任何这些代码行时.

This works without the headers but when I add any of these lines of code in between the httpRequest and stringWriter lines.

    httpRequest.Headers.Add("blah", "1234");
    httpRequest.Headers["blah"] = "1234";

抛出

发生类型为'System.PlatformNotSupportedException'的异常 在System.Web.dll中，但未在用户代码中处理

An exception of type 'System.PlatformNotSupportedException' occurred in System.Web.dll but was not handled in user code

• 为什么我会收到该例外?
• 是否可以将标头添加到 HttpContext 进行测试 WebApi控制器?
• Why am I getting that exception?
• Is there a possible way to add headers to HttpContext for testing WebApi controllers?

推荐答案

我刚刚发现，使用 HttpRequestMessage类，您可以轻松添加标头来测试 WebAPI控制器，而无需必须创建任何伪造 HttpContext .

I just discovered that with HttpRequestMessage class, you can easily add headers for testing your WebAPI controllers without having to create any fake HttpContext.

var request = new HttpRequestMessage(HttpMethod.Get, "http://stackoverflow");
request.Headers.Add("deviceId","1234");
_myController.Request = request;
