路由属性不能正常工作

Question

我的Web-API-2应用程序使用Route属性来定义路由，但它看起来不像我预期的那样工作：从后端返回错误405或404。 操作方法搜索没有开始（里面有断点）。

我的代码，请求和响应以下：

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; 
... 

类WebApiConfig：

public static class WebApiConfig 
    { 
     public static void Register(HttpConfiguration config) 
     { 
      // Web API configuration and services 

      //use authetication handler 
      config.MessageHandlers.Add(new HomeCinemaAuthHandler()); 

      // Enable Route attributes 
      config.MapHttpAttributeRoutes(); 

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

全球。一个sax.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(); 

     } 
    } 

我的要求：

GET http://localhost:65386/api/customers/search/?page=0&pageSize=4 HTTP/1.1 
Accept: application/json, text/plain, */* 
Referer: http://localhost:65386/

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

更新1：

我改变JS代码：

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) 
{ 

和它的作品:)。

但是，当控制器有动作：

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

错误仍然错误405不允许的方法。为什么？

Answer 1

我找到了解决方案:)我是我愚蠢的错误:)。我加错了名字空间

using System.Web.Mvc;

，而不是

using System.Web.Http;

它的工作，但很奇怪的:)。

Answer 2

您的//localhost:65386/api/customers/search/?page=0&pageSize=4获取请求与您的路由配置不符。

[Route("search/?{page:int=0}/{pageSize=4}/{filter?}")]定义4路由属性：

1. 搜索
2. ？：{ε滤波器} {页INT = 0}
3. {的pageSize = 4}

这导致你的第一个错误：你混合querystrings和路由配置。如果你想使用querystrings，只需使用它们。它们不属于路线属性。 这会使您的路由配置无效。

你有两个选择现在：页面属性之前删除问号和改变你的GET请求

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

或删除您的路由数据的注释，并用普通的查询字符串的工作：//localhost:65386/api/customers/search?page=0&pageSize=4&filter=something

Answer 3

基本提示！ System.Web.Http一个用于Web API; System.Web.Mvc一个是以前的MVC版本。 MVC是Web应用程序，Web API是HTTP服务。
