问题描述
我有以下API名为机构的实体
I have an entity named Agency with following apis
GET http://localhost:37331/api/agency?start=1&limit=10&status=1
GET http://localhost:37331/api/agency/2
POST http://localhost:37331/api/agency
PUT http://localhost:37331/api/agency
DELETE http://localhost:37331/api/agency/4
POST http://localhost:37331/api/agency/activate/3
POST http://localhost:37331/api/agency/deactivate/3
GET http://localhost:37331/api/agency/types
我使用的路由模板
The route templates I used are
config.Routes.MapHttpRoute(
name: "ControllerActionIdApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { },
constraints: new { id = @"\d+" }
);
//
config.Routes.MapHttpRoute(
name: "ControllerActionApi",
routeTemplate: "api/{controller}/{action}"
);
//
config.Routes.MapHttpRoute(
name: "ControllerIdApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { },
constraints: new { id = @"\d+" }
);
//
config.Routes.MapHttpRoute(
name: "ControllerApi",
routeTemplate: "api/{controller}"
);
显然,是第二和第三之间的暧昧。我有一个变通方法,把ID为查询字符串
Obviously there is ambiguous between the 2nd and 3rd. I do have a workaround that put the id into query string
GET http://localhost:37331/api/agency?id=2
DELETE http://localhost:37331/api/agency?id=4
我认为必须有聪明的办法。能否请你说明一下吗?
I think there must be smart way. Could you please suggest on this?
感谢
推荐答案
在序列匹配的路由。您的约束:新{ID = @\\ D +}第三路线没有得到一个查找,因为第二个途径将永远是赢家。
The routes are matched in sequence. Your constraint: new { id = @"\d+" } on the 3rd route isn't getting a look-in because the 2nd route will always win.
所以,交换你的第二个和第三个左右的路线。
So swap your 2nd and 3rd routes around.
始终把最有选择性的路线在顶部。
Always put the most selective routes at the top.
config.Routes.MapHttpRoute(
name: "ControllerActionIdApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { },
constraints: new { id = @"\d+" }
);
//
config.Routes.MapHttpRoute(
name: "ControllerIdApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { },
constraints: new { id = @"\d+" }
);
//
config.Routes.MapHttpRoute(
name: "ControllerActionApi",
routeTemplate: "api/{controller}/{action}"
);
//
config.Routes.MapHttpRoute(
name: "ControllerApi",
routeTemplate: "api/{controller}"
);
