本文整理了Java中java.net.URLConnection.setDoOutput()方法的一些代码示例，展示了URLConnection.setDoOutput()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.setDoOutput()方法的具体详情如下：
包路径：java.net.URLConnection
类名称：URLConnection
方法名：setDoOutput

URLConnection.setDoOutput介绍

[英]Sets the flag indicating whether this URLConnection allows output. It cannot be set after the connection is established.
[中]设置指示此URLConnection是否允许输出的标志。连接建立后无法设置。
