c# – ASP.NET Core 2.1 Routing – CreatedAtRoute – 没有路由匹配提供的值

我有以下情况

   [Route("api/[controller]")]
    [ApiController]
    public class FooController: ControllerBase
    {
            [HttpGet("{id}", Name = "GetFoo")]
    public ActionResult<FooBindModel> Get([FromRoute]Guid id)
            {
              ...
            }
    }

   [Route("api/[controller]")]
    [ApiController]
    public class Foo2Controller: ControllerBase
    {

        [HttpPost("/api/Foo2/Create")]
   public ActionResult<GetFooBindModel> Create([FromBody]PostFooBindModel postBindModel)
            {
              ...

            return CreatedAtRoute("GetFoo", new { id = getBindModel.Id }, getBindModel);

            }
    }

PS：getBindModel是GetFooBindModel类型的实例.我正在接受

InvalidOperationException: No route matches the supplied values.

我也尝试更改行返回CreatedAtRoute(“GetFoo”,new {id = getBindModel.Id},getBindModel);

至

return CreatedAtRoute("api/Foo/GetFoo", new { id = getBindModel.Id }, getBindModel);

但仍然是同样的错误.

解决方法:

将FooController中的操作方法(Get)的名称与HttpGet Attribute上的路由名称相匹配.您可以在c#中使用nameof关键字：

[HttpGet("{id}", Name = nameof(Get))]
public ActionResult<FooBindModel> Get([FromRoute]Guid id)
{
          ...
}

而且,而不是硬编码路由名称再次使用名称：

return CreatedAtRoute(nameof(FooController.Get), new { id = getBindModel.Id }, getBindModel);

然后再试一次;
