我有一个FakeHttpContext我一直在尝试修改以包含一些标题用于测试目的
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;
}
这可以在没有标题的情况下工作,但是当我在httpRequest和stringWriter行之间添加任何这些代码行时.
httpRequest.Headers.Add("blah","1234");
httpRequest.Headers["blah"] = "1234";
它抛出
An exception of type ‘System.PlatformNotSupportedException’ occurred
in System.Web.dll but was not handled in user code
解决方法
我刚刚发现,使用HttpRequestMessage类,您可以轻松添加标头以测试WebAPI控制器,而无需创建任何假的HttpContext.
var request = new HttpRequestMessage(HttpMethod.Get,"http://stackoverflow");
request.Headers.Add("deviceId","1234");
_myController.Request = request;
