Question

我正在尝试从我的API获得任何回复。我已经阅读了很多，但任何方式获得404（无法找到资源。）这是我的代码

Web.config:

<authentication mode="Forms">
    <forms loginUrl="~/Account/Login" defaultUrl="~/Home/Index">
    </forms>
</authentication>

的Global.asax.cs

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

WebApiConfig.cs

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

    // Web API routes



    config.MapHttpAttributeRoutes();

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


    // webapi return json
    // http://stackoverflow.com/questions/9847564/how-do-i-get-asp-net-web-api-to-return-json-instead-of-xml-using-chrome
    config.Formatters.JsonFormatter.SupportedMediaTypes.Add(new MediaTypeHeaderValue("text/html"));
}

ApiController：

public class MyAppApiController : ApiController
{
    public HttpResponseMessage Test()
    {
        return Request.CreateResponse(HttpStatusCode.OK, new { Success = true, bbb = "assssdfv[spld[ssadf[ps" });
    }

    public HttpResponseMessage Login(LoginViewModel loginVM)
    {
        var url = this.Url.Link("Default", new { Controller = "AccountController", Action = "Login", model = loginVM});
        return Request.CreateResponse(HttpStatusCode.OK, new { Success = true, RedirectUrl = url });
    }
}

我正在使用Google Chrome简单REST客户端进行测试：

以管理员身份运行我的VS
调试我的应用程序（localhost：12345随我的网站打开）
粘贴到Google Chrome简单REST客户端：
```
http://localhost:12345/api/Test   
```
并运行GET =＆gt;结果404（未找到资源）
粘贴到Google Chrome简单REST客户端：
```
http://localhost:12345/api/Login 
```
字段数据和标头无效并运行POST =＆gt;结果404（未找到资源）

我的代码在哪里出错？

更新：

我已更新：

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

之后我的代码是

config.MapHttpAttributeRoutes();

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

作品但我仍然得到404错误 - 但错误是新的： {"Message":"No HTTP resource was found that matches the request URI 'http://localhost:12345/api/Login'.","MessageDetail":"No type was found that matches the controller named 'Login'."}我的控制器名称是

myProjApiController :ApiController

但是

http://localhost:12345/api/myProjApiController/Login'

结果：

404 No type was found that matches the controller named 'myProjApiController'

您收到的是404，因为未配置路由，并且当您取消注释路由配置时可能会收到错误，因为该代码被调用两次，因此尝试定义具有相同名称的路由两次。

您已经说过，在项目范围内搜索“DefaultApi”只会返回WebApiConfig.cs中的结果。尝试使用相同的“WebApiConfig”搜索来查找多个调用。

或者，看看这些人有相同的问题（重复的路线）：

A route named "x" is already in the route collection. Route names must be unique. Exception with ASP.NET MVC 3
A route named 'DefaultRoute' is already in the route collection. Route names must be unique
A route named 'DefaultApi' is already in the route collection

我做错了什么？试图从API获得响应
