我正在使用vs2012并使用" ASP.net Web Api 2"开始了一个新项目。模板。完成编码并开始测试系统。我观察到路由的奇怪行为。如:
以下是我的路线:
config.Routes.MapHttpRoute(
name: "personRoute",
routeTemplate: "api/px/{action}/{personid:Guid}",
defaults: new { controller = "px", personid = RouteParameter.Optional }
);
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);
这是我的控制器:
public class PxController : ApiController {
private Configuration.DatabaseContext dbctx = new Configuration.DatabaseContext();
[HttpGet]
public IEnumerable<Models.Person> GetAll() {
return dbctx.Persons.ToArray();
}
[ActionName( "op" )]
[HttpGet]
public Models.Person ById( Guid personid ) {
var data = dbctx.Persons.FirstOrDefault( e => e.PersonId == personid );
if (data == null) {
throw new HttpResponseException( HttpStatusCode.NotFound );
}
return data;
}
[ActionName( "op" )]
[HttpPost]
public void Insert( [FromBody] Models.Person newPerson ) {
dbctx.Persons.Add( newPerson );
dbctx.SaveChanges();
}
[ActionName( "op" )]
[HttpPut]
public void Update( [FromBody]Models.Person eperson ) {
var data = dbctx.Persons.FirstOrDefault( e => e.PersonId == eperson.PersonId );
if (data == null) {
throw new HttpResponseException( HttpStatusCode.NotFound );
}
dbctx.Entry( eperson ).State = System.Data.Entity.EntityState.Modified;
dbctx.SaveChanges();
}
[ActionName( "op" )]
[HttpDelete]
public void DeleteById( Guid personid ) {
var data = dbctx.Persons.FirstOrDefault( e => e.PersonId == personid );
if (data == null) {
throw new HttpResponseException( HttpStatusCode.NotFound );
}
dbctx.Entry( data ).State = System.Data.Entity.EntityState.Deleted;
dbctx.SaveChanges();
}
#region |:.Extended Queries.:|
[HttpGet]
public IEnumerable<RemoteProperty> Properties( Guid personid ) {
var data = from n in dbctx.RemoteProperties
where n.PersonId == personid && n.ParentId == null
orderby n.PropertyType.Name
select n;
if (data == null)
throw new HttpResponseException( HttpStatusCode.NotFound );
foreach (var rp in data) {
rp.Details = dbctx.RemoteProperties.SqlQuery( "SELECT * FROM properties WHERE parentid = @parid" ).ToArray();
}
return data.ToArray();
}
[HttpGet]
public IEnumerable<Relation> Relations( Guid personid ) {
var data = from n in dbctx.Relations
where n.PersonId == personid
select n;
if (data == null)
throw new HttpResponseException( HttpStatusCode.NotFound );
return data.ToArray();
}
#endregion
[NonAction]
protected override void Dispose( bool disposing ) {
if (dbctx != null && dbctx is IDisposable) {
dbctx.Dispose();
}
base.Dispose( disposing );
}
}
这些是查询的Fiddler输出:
http://localhost:49318/api/px/GetAll
/* Works as expected */
http://localhost:49318/api/px/op/dfc737ca-312c-e411-ae3c-78843ccba6ef
/* The requested resource does not support http method 'GET'. */
http://localhost:49318/api/px/op?personid=dfc737ca-312c-e411-ae3c-78843ccba6ef
/* Returns the data with personid, but why the above query fails? */
http://localhost:49318/api/px/properties?personid=dfc737ca-312c-e411-ae3c-78843ccba6ef
/* Returns the data with personid */
http://localhost:49318/api/px/properties/dfc737ca-312c-e411-ae3c-78843ccba6ef
/* No action was found on the controller 'Px' that matches the request */
我的问题是这种行为可能是什么原因?我也不能使用像(因为它们不工作)的路线:
"api/{controller}/{personid}/{action}"

尝试使用[Route]属性而不是[Action]属性。
在我的控制器上,我已成功使用以下内容:
[RoutePrefix("api/Demo")] // Sets the base route for actions in this controller
public class DemoController : ApiController
{
[HttpGet]
[Route("DemoAction")] // This makes this function map to route http://site/api/Demo/DemoAction
public IHttpActionResult PerformComplexApiAction(int id)
{
...
可以省略[RoutePrefix],并且可以在每个函数的单个[Route]条目中提供完整路径。

确定。通过检查整个项目并应用更改(如下所列),我成功地完成了它的工作。所以这就是我所做的:
对于调试项目,有一个&#34;跟踪&#34; MS提供的装配,我用它。它将跟踪消息放入输出窗口,在路由时执行的操作等等。所以我能够看到发生了什么。 VS 2012更新还不足以让它发挥作用。
