如何执行删除请求而不返回类型或回调?(改造)

I need perform a DELETE request using Retrofit. So, my code snippet of the interface looks like this:

我需要使用Retrofit执行删除请求。因此，我的接口代码片段如下:

@DELETE("/api/item/{id}")
void deleteItem(@Path("id") int itemId);

But I get the error:

但我得到了一个错误:

java.lang.IllegalArgumentException: ApiItem.deleteItem: Must have either a return type or Callback as last argument.

. lang。IllegalArgumentException: ApiItem.deleteItem:必须有返回类型或回调作为最后一个参数。

However, according to the rules of Rest API, I shouldn't receive any response to DELETE request. How should I specify it in the interface?

但是，根据Rest API的规则，我不应该收到任何删除请求的响应。如何在接口中指定它?

Thanks.

谢谢。

You have to add Callback as last argument in request method if you want to have void method. You can useCallback<Response>.

如果想要使用void方法，就必须在request方法中添加回调作为最后一个参数。你可以useCallback响应> <。

You have to change this:

你必须改变这一点:

@DELETE("/api/item/{id}")
void deleteItem(@Path("id") int itemId);

to :

@DELETE("/api/item/{id}")
void deleteItem(@Path("id") int itemId, Callback<Response> callback);

Or you can return just Response

或者你可以只返回响应

@DELETE("/api/item/{id}")
Response deleteItem(@Path("id") int itemId);
