接口只能调一次 这点好做利用 service 单例特征 然而怎么同步到 scope 上呢 定义一个方法返回数据吗 但是获取是异步的啊 调用方法的时候不一定就取到数据了啊 还有一种就是把 scope 传参到 service 里吗异步去更新 scope 但是貌似不推荐这么做啊…… 求解决方案~
学习是最好的投资！
I can understand that you need to synchronize, that is, wait for the data to be obtained before calling the method
angular’s promise should be what you want

The service layer is only used to request interfaces, and callbacks and data operations are done in the controller
