问题描述
在 Android 上,我最初实现了这样的 Retrofit 界面:
@DELETE(USER_API_BASE_URL + "/{id}")public void deleteUser(@Path("id") String id, Callback callback);
成功删除后,服务器返回 204 NO CONTENT.这导致回调触发失败,带有 retrofit.RetrofitError: End of input at character 0 of
,因为它期望 User
对象返回响应.>
然后我像这样重写它,使用 Void
而不是 User
:
@DELETE(USER_API_BASE_URL + "/{id}")public void deleteUser(@Path("id") String id, Callback callback);<-- 无效
但是我从回调中得到了同样的错误.解决此问题的正确方法是什么?谢谢.
Retrofit 2.x
不再有其他答案中提到的 ResponseCallback
.您想使用 Response
类型.
RxJava 声明:
@PUT Observable富();
标准声明:
@PUT Call酒吧();
On Android, I initially implemented a Retrofit interface like this:
@DELETE(USER_API_BASE_URL + "/{id}")
public void deleteUser(@Path("id") String id, Callback<User> callback);
The server returns 204 NO CONTENT upon a successful deletion. This was causing the callback to trigger failure, with retrofit.RetrofitError: End of input at character 0 of
, as it was expecting a User
object back with the response.
I then rewrote it like this, using Void
instead of User
:
@DELETE(USER_API_BASE_URL + "/{id}")
public void deleteUser(@Path("id") String id, Callback<Void> callback); <-- VOID
But I am getting the same error from the callback.What is the proper way to fix this? Thank you.
Retrofit 2.x
no longer has a ResponseCallback
as mentioned in the other answer. You want to use a Response<Void>
type.
The RxJava declaration:
@PUT Observable<Response<Void>> foo();
The standard declaration:
@PUT Call<Response<Void>> bar();
