类名称：URLConnection
方法名：getOutputStream

URLConnection.getOutputStream介绍

[英]Returns an OutputStream for writing data to this URLConnection. It throws an UnknownServiceException by default. This method must be overridden by its subclasses.
[中]返回用于将数据写入此URLConnection的OutputStream。默认情况下，它会抛出UnknownServiceException。此方法必须由其子类重写。
