今天想研究一下WebApi,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
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 static class GlobalConfiguration
{
private static Lazy _cOnfiguration= new Lazy(delegate {
HttpConfiguration cOnfiguration= new HttpConfiguration(new HostedHttpRouteCollection(RouteTable.Routes));
configuration.Services.Replace(typeof(IAssembliesResolver), new WebHostAssembliesResolver());
configuration.Services.Replace(typeof(IHttpControllerTypeResolver), new WebHostHttpControllerTypeResolver());
configuration.Services.Replace(typeof(IHostBufferPolicySelector), new WebHostBufferPolicySelector());
return configuration;
});
public static HttpConfiguration Configuration
{
get
{
return _configuration.Value;
}
}
//...
}
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}"。
