AttributeRouting不使用HttpConfiguration对象编写集成测试

Question

我正在按照这里概述的思想创建一些集成测试：http://www.strathweb.com/2012/06/asp-net-web-api-integration-testing-with-in-memory-hosting/

当我尝试从手工构建的HttpConfiguration对象注册路由时，我会得到以下错误：“带有路由模板‘api/inboundHttpMethod/{id}’的约束条目'inboundHttpMethod‘必须有一个字符串值，或者是实现’IHttpRouteConstraint‘的类型。”

示例代码:控制器：

 [RoutePrefix("api")]
    public class ContactsController : ApiController
    {
        [GET("Contacts/{id}",RouteName="GetContactsById")]
        public ContactDTO Get(int id)
        {
      return new ContactDTO{ ID =1, Name="test"};
        }
    }
}

TestClass (MSTest)：

 [TestClass]
    public class ContactsTest
    {
        private string _url = "http://myhost/api/";
        private static HttpConfiguration config = null;
        private static HttpServer server = null;
        private HttpRequestMessage createRequest(string url, string mthv, HttpMethod method)
        {
             var request = new HttpRequestMessage();
            request.RequestUri = new Uri(_url + url);
            request.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue(mthv));
            request.Method = method;
            return request;
        }
        private HttpRequestMessage createRequest<T>(string url, string mthv, HttpMethod method, T content, MediaTypeFormatter formatter) where T : class
        {
            HttpRequestMessage request = createRequest(url, mthv, method);
            request.Content = new ObjectContent<T>(content, formatter);

            return request;
        }

        [ClassInitializeAttribute]
        public static void ClassInitialize(TestContext ctx)
        {
            config = new HttpConfiguration();
            config.IncludeErrorDetailPolicy = IncludeErrorDetailPolicy.Always;
            config.Services.Replace(
                typeof(IDocumentationProvider), new DocProvider());

            config.Services.Replace(
                typeof(IApiExplorer),
                new VersionedApiExplorer(config));

            config.Services.Replace(
                typeof(IHttpControllerSelector),
                new VersionHeaderVersionedControllerSelector
                    (config)
                    );
            AttributeRoutingHttpConfig.RegisterRoutes(config.Routes);
            WebApiConfig.Register(config);
            server = new HttpServer(config);
        }

        public static void ClassCleanup()
        {
            config.Dispose();
            server.Dispose();
        }

        [TestMethod]
        public void RetrieveContact()
        {
            var request = createRequest("Contacts/12","application/json",HttpMethod.Get);
            var client = new HttpClient(server);

            using (HttpResponseMessage response = client.SendAsync(request).Result)
            {
                Assert.IsNotNull(response.Content);
            }
        }
    }

错误发生在行"client.SendAsync“上。我检查了AttributeRouting.Web.Http.WebHost.Constraints.InboundHttpMethodConstraint，并检查了config.Routes的“约束”的数据类型，其中显示了一个字符串值。任何帮助都将不胜感激。

也有同样的问题。在这里找到答案：

https://github.com/mccalltd/AttributeRouting/issues/191

你需要替换

AttributeRoutingHttpConfig.RegisterRoutes(config.Routes);

使用

config.Routes.MapHttpAttributeRoutes(cfg =>
{
   cfg.InMemory = true;
   cfg.AutoGenerateRouteNames = true;
   cfg.AddRoutesFromAssemblyOf<ContactsController>();// Or some other reference...
});

我发现我也需要AutoGenerateRouteNames部分。
