-There is a notable difference between the two methods except the arguments. **getBatchDataWithKeys** will invoke different sync methods(since the keys are different) one by one when corresponding data is missing. However, **getBatchDataWithIds** will collect missing data, push their ids to a array, then pass the array to the corresponding sync method(to avoid too many requests), so you need to implement array query on server end.    
-这两个方法除了参数形式不同，还有个值得注意的差异。**getBatchDataWithKeys**会在数据缺失时挨个调用不同的sync方法(因为key不同)。但是**getBatchDataWithIds**却会把缺失的数据统计起来，将它们的id收集到一个数组中，然后一次传递给对应的sync方法(避免挨个查询导致同时发起大量请求)，所以你需要在服务端实现通过数组来查询返回。
