通过自托管路由和集成测试 web api

Question

我正在使用此代码：

[Fact]
public void ValueController_WithGetMethos_ShouldReturnValidData_NoBaseClass()
{
    var configuration = new HttpSelfHostConfiguration("http://localhost:64466");
    configuration.IncludeErrorDetailPolicy = IncludeErrorDetailPolicy.Always;
    configuration.Services.Replace(typeof(IAssembliesResolver), new WebApiClassBase.TestAssemblyResolver(typeof(ValuesController)));

            configuration.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );

    var server = new HttpSelfHostServer(configuration);
    try
    {
    server.OpenAsync().Wait();

    var request = new HttpRequestMessage
    {
        RequestUri = new Uri("http://localhost:64466/api/values"),
        Method = HttpMethod.Get
    };

    var client = new HttpClient(server);
    using (HttpResponseMessage response = client.SendAsync(request).Result)
    {
        response.Should().Not.Be.Null();
        response.IsSuccessStatusCode.Should().Be.True();

        string[] result = response.Content.ReadAsAsync<string[]>().Result;

        result.Length.Should().Be.EqualTo(4);
        result[0].Should().Be.EqualTo("http://tostring.it");
        result[1].Should().Be.EqualTo("http://imperugo.tostring.it");
        result[2].Should().Be.EqualTo("http://twitter.com/imperugo");
        result[3].Should().Be.EqualTo("http://www.linkedin.com/in/imperugo");
    }
    }
    finally
    {
    configuration.Dispose();
    server.Dispose();
    }
}

灵感来自 this, which also contains the relevant ValuesController。我注意到我必须调整路由：

configuration.Routes.MapHttpRoute(
    name: "DefaultApi",
    routeTemplate: "api/{controller}/{id}",
    defaults: new { id = RouteParameter.Optional }
);

根据我的 WebApiConfig 中的那个。但是，当我尝试访问具有如下属性路由的 Action 时：

Route("Calculator/AddTwoNumbers/a/{a}/b/{a}")]
public IHttpActionResult AddTwoNumbers(PayLoad payLoad)

我收到 404 - 未找到错误。我还必须定义这个声明式路由吗？如果是这样，集成测试似乎很乏味。任何反馈将不胜感激。谢谢。

PS:

我试过了：

configuration.MapHttpAttributeRoutes();

这似乎没有帮助

在配置默认路由之前，您需要先设置 AttributeRouting。

configuration.MapHttpAttributeRoutes();
configuration.Routes.MapHttpRoute(
    name: "DefaultApi",
    routeTemplate: "api/{controller}/{id}",
    defaults: new { id = RouteParameter.Optional }
);

路由按添加到 RouteCollection 的顺序进行评估。如果您的默认路由排在第一位，那么它将在您的属性路由有机会匹配之前匹配传入路由。
