添加Web API到现有的MVC Web应用程序后，404错误 [英] 404 error after adding Web API to an existing MVC Web Application

问题描述

的有一个很大的问题在这里：的<一个href=\"http://stackoverflow.com/questions/11990036/how-to-add-web-api-to-an-existing-asp-net-mvc-4-web-application-project\">How对Web API添加到现有的ASP.NET MVC 4 Web应用程序项目？

不幸的是，这是不够的，解决我的问题。我已经试了两次，以确保我没有做错任何事。我右键点击控制器，并补充该项目的Web API 2控制器的操作，使用实体框架里，我选择我的模型类和数据库环境。一切都很好...但仍...每次我试图访问/ API /休息，我得到一个404错误（我的控制器是RestController的名称）。

Unfortunately, it wasn't enough to solve my problem. I've tried twice to be sure I haven't done anything wrong. I right clicked on "Controllers" and added the item "Web API 2 Controller with actions, using Entity Framework" where I selected my model class and db context. Everything went fine... but still... everytime I've tried to access /api/Rest I was getting a 404 error (The name of my Controller is RestController).

推荐答案

它的工作！我不想相信，但你猜怎么着，这个问题与在Global.asax路由为了与

It's working!!! I didn't want to believe, but guess what, the problem was related with the Global.asax routing order.

尽管它不与工作：

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();
    FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
    RouteConfig.RegisterRoutes(RouteTable.Routes);
    GlobalConfiguration.Configure(WebApiConfig.Register); //I AM THE 4th
    BundleConfig.RegisterBundles(BundleTable.Bundles);
}      

它适用于：

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();
    GlobalConfiguration.Configure(WebApiConfig.Register); //I AM THE 2nd
    FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
    RouteConfig.RegisterRoutes(RouteTable.Routes);
    BundleConfig.RegisterBundles(BundleTable.Bundles);
}      

疯了，我知道了。

Crazy, I know.
