如何在 Groovy 脚本中从库函数中获取键/值

Question

我正在尝试在 Groovy 中创建一个库，可以从 Jenkins 创建 JIRA 问题。我能够创建问题，但如何将函数输出重定向到变量以从显示在控制台上的 json 输出中过滤特定的键/值？

控制台输出从我想要导出的位置打印如下，

id

和

key

[Pipeline] sh (hide)
...
...
{"id":"89000","key":"MyKEY-12","self":"https://MyORG.atlassian.net/rest/api/2/issue/89000"}

这是我创建的库函数

def call(Map config=[:]) {
  def rawBody = libraryResource 'com/org/api/jira/createIssue.json'
  def binding = [
    key: "${config.key}",
    summary: "${config.summary}",
    description: "${config.description}",
    issuetype: "${config.issuetype}"
  ]
  def render = renderTemplate(rawBody,binding)
  def response = sh('curl -D- -u $JIRA_CREDENTIALS -X POST --data "'+render+'" -H "Content-Type: application/json" $JIRA_URL/rest/api/2/issue')

  return response
}

这是我调用函数的管道

@Library("jenkins2jira") _
pipeline {
    agent any
    stages {
        stage('create issue') {
            steps {
                jiraCreateIssue(key: "MyKEY", summary: "New JIRA Created from Jenkins", description: "New JIRA body from Jenkins", issuetype: "Task")
            }
        }
    }
}

要实现您想要的效果，只需修改

sh

步骤以返回输出，然后将其读取为 JSON 并将其转换为将由您的函数重新调整的字典。

例如，您可以将 jiraCreateIssue.groovy 更改为：

def call(Map config=[:]) {
  def rawBody = libraryResource 'com/org/api/jira/createIssue.json'
  def binding = [
     key: config.key,
     summary: config.summary,
     description: config.description,
     issuetype: config.issuetype
  ]
  def render = renderTemplate(rawBody,binding)
  def response = sh script:'curl -D- -u $JIRA_CREDENTIALS -X POST --data "render" -H "Content-Type: application/json" $JIRA_URL/rest/api/2/issue', returnStdout: true
  def dict = readJSON text: response 
  return dict  // return a dictionary containing all the response values
}

** 使用管道实用程序步骤插件中的 readJSON 步骤。
比在您的管道中您可以使用结果：

stage('create issue') {
    steps {
        script {
           def result = jiraCreateIssue(key: "MyKEY", summary: "New JIRA Created from Jenkins", description: "New JIRA body from Jenkins", issuetype: "Task")
           println(result.id)   // access the returned id
           println(result.key)  // access the returned key
        }
    }
}

就是这样，扔出返回的字典你就可以访问所有需要的响应值。
