Web Api 404错误找不到资源 [英] Web Api 404 error The resource cannot be found

问题描述

我尝试使用Web Api从服务器发送/获取数据.WebApiConfig.cs:

I try to use Web Api for send/get data from server. WebApiConfig.cs :

    config.MapHttpAttributeRoutes();

    config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "{controller}/{action}"
        );

RouteConfig.cs:

RouteConfig.cs:

public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
        routes.MapRoute(
                            name: "Default",
                            url: "{controller}/{action}/{id}",
                            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
                    );
    }

Globa.asax.cs:

Globa.asax.cs:

    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);
        GlobalConfiguration.Configure(WebApiConfig.Register);

    }

Api控制器(ServicesController.cs):

Api controller (ServicesController.cs):

public class ServicesController : ApiController
{

    public List<TreeMenuItem> LoadMetadata()
    {
        List<TreeMenuItem> itemsMenu = new List<TreeMenuItem>();
        TreeMenuItem dataSource = new TreeMenuItem("1", "DataSources", null);
        itemsMenu.Add(dataSource);
        return itemsMenu;
    }
}

我正在尝试从如下波纹管的angularJS控制器访问api:

I'm trying to access api from angularJS controller like bellow:

angular.module("App", ["ngRoute", "ngResource"])
.controller('MainController', ["$scope", "$http", MainController]);

function MainController($scope, $http) {
var baseUrl = "Services/LoadMetadata";
var params = {};
$http.post(baseUrl, params)
    .then(function (data) {
        $scope.roleList = data.data;
});
}

我在$ http.post上收到服务/LoadMetadata"错误4​​04！我使用路由尝试了一些版本-相同的错误404.有帮助吗?

I get error 404 on $http.post for "Services/LoadMetadata"! I tried some version using route - same error 404. Any help?

推荐答案

更改注册顺序...

    GlobalConfiguration.Configure(WebApiConfig.Register);  
    RouteConfig.RegisterRoutes(RouteTable.Routes);
    BundleConfig.RegisterBundles(BundleTable.Bundles);

在route-config之前注册web-api-config，因为我猜想route-config正在干预web-api-config ...

register web-api-config before route-config because i guess route-config is meddling with the web-api-config...

还请考虑将所有api调用都加api的标准做法.

also please do consider the standard practice of having all your api calls prefixed with api.

  config.Routes.MapHttpRoute(
        name: "DefaultApi",
        routeTemplate: "api/{controller}/{action}"
    );
