有人可以帮我解决路由问题吗?
在 WebApiConfig 中,我有这个映射
config.Routes.MapHttpRoute(DefaultApi",
routeTemplate: "{controller}/{uid}",
defaults: new {uid = RouteParameter.Optional}
);
和控制器中的两个方法
[RoutePrefix("AppartmentCategory")]
public class AppartmentCategoryController : ApiController
{
[HttpGet]
public IHttpActionResult Get(Guid uid){...}
[HttpGet]
[Route("{propertyUid?}")]
public IHttpActionResult GetList(Guid propertyUid){...}
}
当我尝试发送请求时
1. http://.../AppartmentCategory/043F61D1-7194-E611-A98B-9C5C8E0005FA
和
2. http://.../AppartmentCategory/?propertyUid=2fdc968d-0192-e611-a98b-9c5c8e0005fa
在两种情况下执行方法 public IHttpActionResult GetList(Guid propertyUid)
我为第一次请求执行公共IHttpActionResult Get(Guid uid)方法的原因是什么?
答案 0 :(得分:1)
您正在混合基于约定的路由和属性路由。 config.MapHttpAttributeRoutes()
在基于约定的路由之前映射(应该如此)
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(DefaultApi",
routeTemplate: "{controller}/{uid}",
defaults: new {uid = RouteParameter.Optional}
);
所以它会首先击中GetLists
,因为第一场比赛总是在匹配模板时获胜。从技术上讲,两种行为都有类似的路线。
[RoutePrefix("AppartmentCategory")]
public class AppartmentCategoryController : ApiController
{
//GET AppartmentCategory/043F61D1-7194-E611-A98B-9C5C8E0005FA VIA CONVENTION-BASED ROUTING
[HttpGet]
public IHttpActionResult Get(Guid uid){...}
//GET AppartmentCategory/2fdc968d-0192-e611-a98b-9c5c8e0005fa VIA ATTRIBUTE ROUTING
[HttpGet]
[Route("{propertyUid?}")]
public IHttpActionResult GetList(Guid propertyUid){...}
}
您应该尝试稍微区分这两个操作,并尝试不在同一个控制器中混合使用基于约定的路由。
[RoutePrefix("AppartmentCategory")]
public class AppartmentCategoryController : ApiController {
//GET AppartmentCategory/043F61D1-7194-E611-A98B-9C5C8E0005FA
[HttpGet]
[Route("{uid:guid}")]
public IHttpActionResult Get(Guid uid){...}
//GET AppartmentCategory?propertyUid=2fdc968d-0192-e611-a98b-9c5c8e0005fa
[HttpGet]
[Route("")]
public IHttpActionResult GetList(Guid propertyUid){...}
}
