本文整理了Java中java.net.URLConnection.getInputStream()方法的一些代码示例，展示了URLConnection.getInputStream()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。URLConnection.getInputStream()方法的具体详情如下：
包路径：java.net.URLConnection
类名称：URLConnection
方法名：getInputStream

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。
