Question

我可以以某种方式获取WebApiConfig的路由映射中的控制器名称吗？

我想要做的是将控制器名称的一部分与动作匹配。

config.Routes.MapHttpRoute(
    name: "ApiGetAllDefault",
    routeTemplate: "api/{controller}/{id}",
    defaults: new { id = RouteParameter.Optional, action = "Get" + controllerName + "s" },
    constraints: new { httpMethod = new HttpMethodConstraint(HttpMethod.Get) }
);

更新：所有这一切的原因是我以

的方式进行路由

config.Routes.MapHttpRoute(
    name: "ApiById",
    routeTemplate: "api/{controller}/{id}",
    defaults: new { id = RouteParameter.Optional },
    constraints: new { id = @"^[0-9]+$" }
);

config.Routes.MapHttpRoute(
    name: "ApiByActionId",
    routeTemplate: "api/{controller}/{action}/{id}",
    defaults: null,
    constraints: new { id = @"^[0-9]+$" }
);

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

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

包含操作名称的api/World/GetWorld/5之类的请求会匹配，但api/World/5之类的其他请求不会或分别与多个操作匹配。由于我没有在路由和动作之间找到正确的默认映射，我有想法为所有控制器定义更具体的路由。

foreach (Type t in GetTypesInNamespace(Assembly.GetExecutingAssembly(), "MyProject.Controllers")) {
    if (typeof(ApiController).IsAssignableFrom(t)) { // Make sure that this controller class is deriving from api controller
        string controllerName = t.Name.Substring(0, t.Name.LastIndexOf("Controller"));  // Remove Controller postfix from name
        config.Routes.MapHttpRoute(
            name: "ApiGet" + controllerName,
            routeTemplate: "api/" + controllerName + "/{id}",
            defaults: new { controller = controllerName, action = "Get" + controllerName },
            constraints: new { id = @"^[0-9]+$", httpMethod = new HttpMethodConstraint(HttpMethod.Get) }
        );

        config.Routes.MapHttpRoute(
            name: "ApiGet" + controllerName + "s",
            routeTemplate: "api/" + controllerName + "/{id}",
            defaults: new { controller = controllerName, id = RouteParameter.Optional, action = "Get" + controllerName + "s" },
            constraints: new { httpMethod = new HttpMethodConstraint(HttpMethod.Get) }
        );
    }
}

此解决方案对我有用，但我仍然想知道是否存在通用路由，以便将没有操作名称的reuqest与默认操作匹配。

你可以像在WebApiConfig

中定义控制器+动作一样

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

OR

您可以查看

routes.MapHttpRoute("DefaultApiWithId", "Api/{controller}/{id}", new { id = RouteParameter.Optional }, new { id = @"\d+" });
routes.MapHttpRoute("DefaultApiWithAction", "Api/{controller}/{action}");
routes.MapHttpRoute("DefaultApiGet", "Api/{controller}", new { action = "Get" }, new { httpMethod = new HttpMethodConstraint(HttpMethod.Get) });
routes.MapHttpRoute("DefaultApiPost", "Api/{controller}", new {action = "Post"}, new {httpMethod = new HttpMethodConstraint(HttpMethod.Post)});

如果您要限制一个控制器，那么您确实喜欢以下操作。

  routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
                  constraints: new {controller = "FrontEnd" }
            );

constraints仅允许FrontEnd控制器

Http路由的控制器名称？
