谁能向我解释CreatedAtRoute()? [英] Can anyone explain CreatedAtRoute() to me?

问题描述

在Web API 2的模板中，post方法始终像这样:

From the template for Web API 2, a post method is always like this:

[ResponseType(typeof(MyDTO))]
public IHttpActionResult PostmyObject(MyDTO myObject)
{
    ...
    return CreatedAtRoute("DefaultApi", new { id = myObject.Id }, myObject);
}

我不理解这种CreatedAtRoute()方法.谁能向我解释CreatedAtRoute()方法?

I don't understand this CreatedAtRoute() method. Can anyone explain the CreatedAtRoute() method to me?

推荐答案

CreatedAtRoute方法用于在调用POST方法存储一些新对象时将URI返回到新创建的资源. 因此，例如，如果您发布一个订单商品，则可能会返回一条类似于"api/order/11"的路径(显然11是订单的ID).

The CreatedAtRoute method is intended to return a URI to the newly created resource when you invoke a POST method to store some new object. So if you POST an order item for instance, you might return a route like 'api/order/11' (11 being the id of the order obviously).

顺便说一句，我同意MSDN文章对理解这一点毫无用处.您实际返回的路由自然取决于您的路由设置.

BTW I agree that the MSDN article is of no use in understanding this. The route you actually return will naturally depend on your routing setup.
