MVC4 WebApi路由与ActionNames不允许通用的"Get"

本文关键字：quot Get 路由 WebApi ActionNames 不允许 MVC4 | 更新日期: 2023-09-27 17:51:14

我一直有麻烦，试图能够有多个"Get"方法，同时也有一个默认的/api/{controller}。以下是一个带有虚拟代码的示例(是的，我意识到它将返回完全相同的代码)。

错误:"Multiple actions were found that match the request"当我试图去/api/courses

转到/api/courses/all工作良好，/api/courses/3也一样

// GET api/courses
public IEnumerable<Courses> Get()
{
    return Db.Courses.OrderBy(x => x.Name);
}
// GET api/courses/all
[ActionName("all")]
public IEnumerable<Courses> GetAll()
{
    return Db.Courses.OrderBy(x => x.Name);
}
// GET api/courses/id
[ActionName("all")]
public Courses Get(int id)
{
    return Db.Courses.Where(x => x.id == id);
}

RouteConfig看起来像:

routes.MapHttpRoute(
       "ApiControllerOnly",
       "api/{controller}"
);
// Allow for numeric Ids to be passed in
routes.MapHttpRoute(
       "ApiControllerAndIntegerId",
       "api/{controller}/{id}",
       null,
       new { id = @"^'d+$" }
);
routes.MapHttpRoute(
       "ApiControllerAction",
       "api/{controller}/{action}"
);

我想要做的是调用:

/api/courses - returns Get()
/api/courses/all - returns GetAll()
/api/courses/3 - returns Get(id = 3)
编辑:

它还需要允许Put, Post等工作，以及Putting的课程/api/courses/

MVC4 WebApi路由与ActionNames不允许通用的"Get"

错误:"多个动作被发现匹配的请求"当我试图去/api/courses

通过为ApiControllerOnly路由指定默认动作为"Get"，我能够使/api/courses工作。这适用于您的场景吗?

        routes.MapHttpRoute(
            name: "ApiControllerOnly",
            routeTemplate: "api/{controller}",
            defaults: new { action = "Get" }
        );

如果你在你的APIController中有额外的Put/Post/etc方法，你应该考虑在ApiControllerOnly路由上使用HttpMethodConstraint，并为Put/Post/etc方法添加另一个路由(即ApiControllerOnly2):

        config.Routes.MapHttpRoute(
            name: "ApiControllerOnly",
            routeTemplate: "api/{controller}",
            defaults: new { action = @"Get" },
            constraints: new { httpMethod = new HttpMethodConstraint(HttpMethod.Get) }
        );
        config.Routes.MapHttpRoute(
            name: "ApiControllerOnly2",
            routeTemplate: "api/{controller}"
        );
        config.Routes.MapHttpRoute(
            name: "ApiControllerAndIntegerId",
            routeTemplate: "api/{controller}/{id}",
            defaults: null,
            constraints: new { id = @"^'d+$" }
        );
        config.Routes.MapHttpRoute(
            name: "ApiControllerAction",
            routeTemplate: "api/{controller}/{action}"
        );
