Question

我有下面的Jenkinsfile，它将通过grep来获取URL中的字符串，它将根据输出将通知发送给Slack。

stage('Check if present') {
    steps  {
        script{   
         sh """
          if curl -s http://example.foo.com:9000 | grep -q "ERROR"
            then  
              slackSend channel: '#team', message: "Pipeline has been failed due to due to an error, please investigate:${env.BUILD_URL} : http://example.foo.com:9000", teamDomain: 'example', tokenCredentialId: 'foo'    
                echo "Scan result: ERROR" && exit 1  
            elif curl -s http://example.foo.com:9000 | grep -q "WARN"
            then
           slackSend channel: '#team', message: "Pipeline is in WARN state due to a warning, please investigate:${env.BUILD_URL} : http://example.foo.com:9000", teamDomain: 'example', tokenCredentialId: 'foo'
             fi"""
         }
       }
    }

因为它是一个插件，所以绝对不会发送slackSend通知。我正在寻找在Groovy中执行相同操作的方法，以便可以实现slackNotification。

作为示例，我在Groovy中尝试了以下逻辑。但这没有用，因为即使该行不存在也就是找到了打印行。

stage('test logic'){
steps{
 script{
     if ('curl -s http://example.foo.com:9000'.execute() | 'grep foo'.execute())
        println("The line is found")
     else {
         println("The line is not found")
         exit 1
     }
       }

}}

您可以只使用Groovy的（更准确地说是Java的）.contains(String)方法来检查某个字符串是否包含其他字符串。同样，当您在管道中执行命令时，您可以捕获该命令的标准输出。

代码：

stage('test logic'){
  steps{
   script{
     def commandStdout = sh(returnStdout: true, script: "curl -s http://example.foo.com:9000"
     if (commandStdout.contains("foo")) {
        println("The line is found")
     }else {
         println("The line is not found")
         exit 1
     }
   }
  }
}

在Groovy中使用grep进行if if else语句高级
