c# - WebApi 2 使用属性路由构建嵌套路由。结果同时映射到两个 Controller

Question

我有两个 Controller ，一个名为“Products”，另一个名为“ProductsGroup”

[RoutePrefix("api/{clientUrl}/products")]
public class ProductsController : BaseApiController
{
    /// <summary>
    /// Get all products from a client
    /// </summary>
    /// <returns></returns>
    [Route("")]
    public HttpResponseMessage Get()
    {
        var model = Repository.GetProducts(ClientId).Select(p => ModelFactory.Create<ProductsModel>(p));
        return Request.CreateResponse(HttpStatusCode.OK, model);
    }
}

[RoutePrefix("api/{clientUrl}/products/groups")]
public class ProductGroupsController : BaseApiController
{
    /// <summary>
    /// Get all productgroups
    /// </summary>
    /// <returns></returns>
    [Route("")]
    public HttpResponseMessage Get()
    {
        var model = Repository.GetProductGroups(ClientId);
        return Request.CreateResponse(HttpStatusCode.OK, model);
    }
}

当我像这样路由 ProductGroupsController 时，由于“发现与 URL 匹配的多个 Controller 类型”，我无法访问

是否可以让路由忽略 url 的“products”部分，只映射到 productgroupscontroller？

Answer 1

考虑对两者使用单个 Controller :

[RoutePrefix("api/{clientUrl}/products")]
public class ProductsController : BaseApiController
{
    [Route("")]
    public HttpResponseMessage GetProducts()  {}

    [Route("groups")]
    public HttpResponseMessage GetProductGroups()  {}
}

或者不使用 RoutePrefixes:

public class ProductsController : BaseApiController
{
    [Route("api/{clientUrl}/products")]
    public HttpResponseMessage Get()  {}
}

public class ProductGroupsController : BaseApiController
{
    [Route("api/{clientUrl}/products/groups")]
    public HttpResponseMessage Get()    {  }
}
