为什么不能通过Retrofit在我的IntentService中循环调用execute来获得多个响应？

public class MyIntentService extends IntentService {
    private ApiService apiService;

    public MyIntentService() {
        super("MyIntentService");
        // 创建Retrofit实例
        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl("https://api.example.com/")
                .addConverterFactory(GsonConverterFactory.create())
                .build();
        // 创建ApiService接口实例
        apiService = retrofit.create(ApiService.class);
    }

    @Override
    protected void onHandleIntent(Intent intent) {
        // 发起异步请求
        Call<ApiResponse> call = apiService.getData();
        call.enqueue(new Callback<ApiResponse>() {
            @Override
            public void onResponse(Call<ApiResponse> call, Response<ApiResponse> response) {
                // 处理响应
                if (response.isSuccessful()) {
                    ApiResponse apiResponse = response.body();
                    // 处理数据
                } else {
                    // 处理错误
                }
            }

            @Override
            public void onFailure(Call<ApiResponse> call, Throwable t) {
                // 处理请求失败
            }
        });
    }
}
