URLConnection.getInputStream介绍

[英]Returns an InputStream for reading data from the resource pointed by this URLConnection. It throws an UnknownServiceException by default. This method must be overridden by its subclasses.
[中]返回一个InputStream，用于从此URLConnection指向的资源中读取数据。默认情况下，它会抛出UnknownServiceException。此方法必须由其子类重写。
