C# 路由属性未按预期工作

我的Web-API-2应用程序正在使用Route属性来定义路由，但它似乎不像我预期的那样工作：从后端返回错误405或404。 操作方法搜索未启动（内部有断点）

我的代码、请求和响应如下：

JS代码：

var url ='/api/customers/search/',
var config = {
                params: {
                    page: 0,
                    pageSize: 4,
                    filter: $scope.filterCustomers
                }
            };
$http.get(url, config).then(function (result) {
                        success(result);
                    }, function (error) {
                        if (error.status == '401') {
                            notificationService.displayError('Authentication required.');
                            $rootScope.previousState = $location.path();
                            $location.path('/login');
                        }
                        else if (failure != null) {
                            failure(error);
                        }
                    });

后端控制器的代码：

//[Authorize(Roles = "Admin")]
[RoutePrefix("api/customers")]
public class CustomersController : ApiControllerBase
{
    private readonly IEntityBaseRepository<Customer> _customersRepository;

    public CustomersController(IEntityBaseRepository<Customer> customersRepository,
        IEntityBaseRepository<Error> _errorsRepository, IUnitOfWork _unitOfWork)
        : base(_errorsRepository, _unitOfWork)
    {
        _customersRepository = customersRepository;
    }


    //[Route("search/?{page:int=0}&{pageSize=4}")]
    [Route("search/?{page:int=0}/{pageSize=4}/{filter?}")]
    [HttpGet]
    public HttpResponseMessage Search(HttpRequestMessage request, int? page, int? pageSize, string filter = null)
    {
        int currentPage = page.Value;
        int currentPageSize = pageSize.Value;
...

Global.asax.css：

public class Global : HttpApplication
    {
        void Application_Start(object sender, EventArgs e)
        {

            var config = GlobalConfiguration.Configuration;

            AreaRegistration.RegisterAllAreas();

            //Use web api routes
            WebApiConfig.Register(config);

            //Autofac, Automapper, ...
            Bootstrapper.Run();

            //Use mvc routes
            RouteConfig.RegisterRoutes(RouteTable.Routes);



            //register bundles
            BundleConfig.RegisterBundles(BundleTable.Bundles);

            GlobalConfiguration.Configuration.EnsureInitialized();

        }
    }

=======================

更新1:

我将JS代码更改为：

 apiService.get('/api/customers/search', config, customersLoadCompleted, customersLoadFailed);

和控制器：

 [HttpGet]
 [Route("search")]
 public HttpResponseMessage Get(HttpRequestMessage request, int? page, int? pageSize, string filter = null)
{

它是有效的：）

但当控制器有动作时：

[HttpGet]
 [Route("search")]
 public HttpResponseMessage Search(HttpRequestMessage request, int? page, int? pageSize, string filter = null)
 { 
...

错误仍然是错误405方法不允许。为什么？

您对

//localhost:65386/api/customers/search/？page=0&pageSize=4的get请求与您的路由配置不匹配

[路由（“搜索/？{page:int=0}/{pageSize=4}/{filter？}”）]
定义4个路由属性：

搜寻
？{page:int=0}
{pageSize=4}
{过滤器？}
这将导致您的第一个错误：您混合了查询字符串和路由配置。如果您想使用querystring，只需使用它们。它们不属于路由属性。
这会使路由配置无效

您现在有2个选择：删除页面属性前的问号，并将get请求更改为

[Route("search/{page:int=0}/{pageSize=4}/{filter?}")]
//localhost:65386/api/customers/search/0/4/optional-filter-value

或者删除路由数据注释，并使用普通查询字符串：
//localhost:65386/api/customers/search？page=0&pageSize=4&filter=something
我找到了解决方案：）我犯了一个愚蠢的错误：）。我添加了错误的名称空间

使用System.Web.Mvc

而不是

使用System.Web.Http

它起作用了，但很奇怪：）。
基本警报！
System.Web.Http
一个用于WebAPI；
System.Web.Mvc
一个用于以前的Mvc版本。MVC是web应用程序，web API是HTTP服务

[Route("search/{page:int=0}/{pageSize=4}/{filter?}")]
//localhost:65386/api/customers/search/0/4/optional-filter-value
