如何使用grovy脚本控制台(jenkins)中的bash向python发送单个管道命令?

如果你不需要用管道把bash导入python,也许这适合你的喜好?

['python','-c','print("this is a sample text")'].execute().text

如果你 做 需要它,试试看

['bash','-c', /echo print\(\"this is a sample text.\"\) | python/].execute().text

使用 List 的 .execute() 有助于澄清每个论点是什么。斜杠字符串通过更改转义符来帮助实现。

print "bash -c 'echo \"print(\\\"this is a sample text.\\\")\" | python'"

输出:

bash -c 'echo "print(\"this is a sample text.\")" | python'

在深入研究之后,我发现了一个与平台无关、支持错误通道(stderr)和执行故障的解决方案,它甚至可以避免操作系统特定的组件,如bash/cmd.exe:

try {
  def command = ['python', '-c', /print("this is a sample text.")/];
  if (System.properties['os.name'].toLowerCase().contains('windows'))
  {
    command[2] = command[2].replaceAll(/\"/, /\\\"/)
  }
  println "command=" + command
  def proc = command.execute()
  def rc = proc.waitFor()
  println "rc=" + rc

  def err = proc.err.text
  if( err != "" ) { print "stderr=" + err }

  def out = proc.text
  if( out != "" ) { print "stdout=" + out }
} catch(Exception e) {
  println "exception=" + e
}
println ""
