问题
当我创建一个具有实际控制上的路线的方法，说：
的API /国家/东西... 的
当我执行上述要求，我的code被执行＆安培;数据被返回。
但是当我尝试调用基控制器我的路线。例如：API /国家/ code / 123的
我得到一个404错误。
问
这是如何实现通用的路由，同时利用属性的路由任何想法？
特定的控制器
[路线preFIX（国家）]
公共类CountryController：MasterDataControllerBase＆LT;国家，CountryDto＆GT;
{
公共CountryController（
IGenericRepository＆LT;国家＆GT;资源库，
IMappingService映射器，
ISecurityService安全）：基地（资料库，映射器，安全）
{
}
}
基本
公共类MasterDataControllerBase＆LT; TEntity，TEntityDto＆GT; ：ControllerBase
其中，TEntity：类，我codedEntity，新的（）
其中，TEntityDto：类，新的（）
{
私人只读IMappingService映射; 私人只读IGenericRepository＆LT; TEntity＆GT;库; 私人只读ISecurityService安全; 公共MasterDataControllerBase（IGenericRepository＆LT; TEntity＆GT;资源库，IMappingService映射器，ISecurityService安全）
{
this.security =安全;
this.mapper =映射;
this.repository =库;
} [路线（code / {code}）]
公共TEntityDto获取（字符串code）
{
this.security.Enforce（AccessRight.CanAccessMasterData）; VAR的结果= this.repository.FindOne（O =方式＆gt;Øcode == code）; 返回this.mapper.Map＆LT; TEntity，TEntityDto＆GT;（结果）;
}
}
属性中的Web API路由不支持路线属性的继承。您可以看到这表明继承= FALSE 如果查看 RouteAttribute 类的定义...
[AttributeUsage（AttributeTargets.Class | AttributeTargets.Method，继承=假，的AllowMultiple = TRUE）]
公共密封类RouteAttribute：属性，IDirectRouteFactory，IHttpRouteInfoProvider
{...
这解释了为什么你得到404，为有效地消失路线属性。
由于属性是不可继承和类是密封的，我不知道是否有一种用自带开箱的属性路由基础设施来做到这一点。
更新：在Web API团队成员解释说，这是一个设计决定，它不是继承... http://stackoverflow.com/a/19989344/3199781
The problem
When I create a method with a route on the actual controller, say:"api/country/something"...
When I perform the above request, my code gets executed & data gets returned.
But when I try call my route on the base controller. E.G: "api/country/code/123"
I get a 404 error.
Question
Any idea on how to implement generic routes whilst making use of attribute routing?
Specific Controller
[RoutePrefix("Country")]
public class CountryController : MasterDataControllerBase<Country, CountryDto>
{
public CountryController(
IGenericRepository<Country> repository,
IMappingService mapper,
ISecurityService security) : base(repository, mapper, security)
{
}
}
Base
public class MasterDataControllerBase<TEntity, TEntityDto> : ControllerBase
where TEntity : class, ICodedEntity, new()
where TEntityDto : class, new()
{
private readonly IMappingService mapper;
private readonly IGenericRepository<TEntity> repository;
private readonly ISecurityService security;
public MasterDataControllerBase(IGenericRepository<TEntity> repository, IMappingService mapper, ISecurityService security)
{
this.security = security;
this.mapper = mapper;
this.repository = repository;
}
[Route("code/{code}")]
public TEntityDto Get(string code)
{
this.security.Enforce(AccessRight.CanAccessMasterData);
var result = this.repository.FindOne(o => o.Code == code);
return this.mapper.Map<TEntity, TEntityDto>(result);
}
}
Attribute routing in Web API doesn't support inheritance of the Route attribute. You can see this indicated by Inherited = false if you view the definition of the RouteAttribute class...
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, Inherited = false, AllowMultiple = true)]
public sealed class RouteAttribute : Attribute, IDirectRouteFactory, IHttpRouteInfoProvider
{ ...
This explains why you're getting the 404, as the Route attribute effectively disappears.
Since the attribute is not inheritable and the class is sealed, I don't know if there's a way to do this with the attribute routing infrastructure that comes out of the box.
Update: A member of the Web API team explains it was a design decision that it's not inherited... http://stackoverflow.com/a/19989344/3199781
