Observable.subscribe介绍

[英]Subscribes to an ObservableSource and ignores onNext and onComplete emissions.

If the Observable emits an error, it is wrapped into an io.reactivex.exceptions.OnErrorNotImplementedExceptionand routed to the RxJavaPlugins.onError handler. Scheduler: subscribe does not operate by default on a particular Scheduler.
[中]订阅一个可观察的资源，忽略下一个和未完成的排放。
如果可观测对象发出错误，它将被包装到io中。reactivex。例外。OnErrorNotImplementedException并路由到RxJavaPlugins。一个错误处理程序。调度程序：订阅默认情况下不会在特定调度程序上运行。
