从android调用Get Api的改造返回空响应，在邮递员中它工作正常

问题描述

我正在使用改装来拨打电话。但是在 API 的响应中它返回 null ，请在下面查看

调用API方法

 @GET(ServerURL.GET_CHAT_DATA)
    Call<ChatData> getChatData(@Query("filter") String filter);

从改造中调用 API

  @Override
    public void getChatData(Context context,final IOnLeadershipExpInteractedListener expInteractedListener) {
 if (Utils.isConnectedToInternet(context)) {

            Call<ChatData> leadershipCall = ServerApiClient.getRetroInstance().getChatData("{}");
            leadershipCall.enqueue(new Callback<ChatData>() {
                @Override
                public void onResponse(Call<ChatData> call,Response<ChatData> response) {
                    expInteractedListener.hideLoadingDialog();
                    if (response.isSuccessful()) {
                        //expInteractedListener.onSuccessChatData(null);//"response.body()");
                    } else {
                        expInteractedListener.onError(response);

                    }
                }

                @Override
                public void onFailure(Call<ChatData> call,Throwable t) {
                    expInteractedListener.hideLoadingDialog();
                    expInteractedListener.onRetroRequestFailure();
                }
            });

        } else {
            expInteractedListener.showNoInternetDialog();
        }
}

模型类是

public class ChatData {
    Result result;
}

我在这里使用这个模型类是因为我在成功响应中获取动态数据，所以我正在手动将该数据解析为代码。

从邮递员那里得到的成功响应就像

}

请帮助我解决此改造 API 调用中的空响应错误。因为我在我的 android studio logcat 中没有收到任何类型的错误。这让人很难理解为什么会发生这种情况。
