今天想研究一下Web Api，写了一个测试Api，打开网站后浏览一下，可是却提示找不到方法，刚开始以为哪里配置错了，可找了半天也没见。
因为我是在一个现有Mvc站点做的Demo，所以打算新建一个Mvc网站，再试一下，新站点是正常的，对比一下Global文件，发现WebApiConfig和RouteConfig顺序不一样。
如果把新站点的RouteConfig也放在WebApiConfig之前，同样提示找不到方法。看来这两个配置有关联呀。

WebApiConfig.Register(GlobalConfiguration.Configuration);RouteConfig.RegisterRoutes(RouteTable.Routes); |
看了一下GlobalConfiguration类就明白了

public
class RouteConfig { public
static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( name: "Default", url: "t/{controller}/{action}/{id}", defaults: new
{ controller = "Home", action = "Index", id = UrlParameter.Optional } ); } } public
static class WebApiConfig { public
static void Register(HttpConfiguration config) { config.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{controller}/{id}", defaults: new
{ id = RouteParameter.Optional } ); } } |
合并后的类似路由：
1 routes.MapHttpRoute( 2 name: "DefaultApi", 3 routeTemplate: "api/{controller}/{id}", 4 defaults: new { id = RouteParameter.Optional } 5 ); 6 routes.MapRoute( 7 name: "Default", 8 url: "{controller}/{action}/{id}", 9 defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional } 10 );
如果顺序反了，DefaultApi的路由就永远匹配不到了，会一直找MVC的路由"{api}/{action}/{id}"。
