Question

我正在使用JSCH调用位于远程计算机上的脚本文件（.sh）。在执行期间，脚本输出错误和成功语句。我写的JSCH代码展示了两个流，InputStream＆amp;错误流

如何获得包含错误和输出的单个输入流？

Channel channel=session.openChannel("exec");
((ChannelExec)channel).setCommand("/opt/sdp/SnapShot/bin/dumpSubscribers.ksh");;
InputStream in=channel.getInputStream();
InputStream error=((ChannelExec)channel).getErrStream();
channel.connect();

**Script output:**

初始化要写入的输出流，然后使用setOutputSteam和setErrStream

而不是getInputStream

OutputStream out = new OutputStream();
channel.setOutputStream(out);
channel.setErrStream(out);

请注意，当通道断开连接时，“out”将关闭。要防止该行为，请在设置输出流时添加布尔值：

channel.setErrStream(out, true);
channel.setOutputSteam(out, true);

如果您在JSCH ChannelExec会话中使用的输出流正在代码中的其他位置重用，这可能很重要。

如果您需要将输出流读入输入流，请参阅this question.
