来自命令行和 Groovy 脚本的 curl 请求

我面临一个我不明白的问题，我编写了一个简单的 groovy 脚本，当从命令行调用时，它按预期工作

#!/usr/bin/env groovy

def jsonParse(def json) {
  new groovy.json.JsonSlurperClassic().parseText(json)
}

def ticketNumbers = ["MYSTATS-2695", "MYSTATS-2694"]

 ArrayList<String> jiraLinks = new ArrayList<String>();

  for(int i =0; i < ticketNumbers.size(); i++) {
    def jira_json = "curl -o /dev/null -X GET -H Content-Type: application/json --cert-type PEM --key-type PEM -E /Users/Jenkins/.jenkins/workspace/certificates/cert.pem --key /Users/Jenkins/.jenkins/workspace/certificates/cert.pem https://jira.dev.org.co.uk:443/rest/api/2/issue/${ticketNumbers[i]}".execute().text;
    def json = jsonParse(jira_json);
    def summary = json['fields']['summary'].toString();
    jiraLinks.add("[" + ticketNumbers[i] + "](https://jira.dev.org.co.uk/browse/" + ticketNumbers[i] + ")" + " - " + summary);
  }

 println "${jiraLinks}"

所以当我这样做的时候 groovy myscript.groovy

这将打印出来

[[MYSTATS-2695 ](https://jira.dev.org.co.uk/browse/MYSTATS-2695 ) - Jenkins build pipeline should ignore draft and pre-releases, [MYSTATS-2694 ](https://jira.dev.org.co.uk/browse/MYSTATS-2694 ) - Android Jenkins pipeline should populate the comscore SDK version automatically]

所以这正如预期的那样。

然后我拥有的是一个 groovy 脚本，我将其称为 jenkins 管道构建的一部分

class Helpers {

   def jsonParse(def json) {
     new groovy.json.JsonSlurperClassic().parseText(json)
   }

  def createJiraLinks(def ticketNumbers) {

    ArrayList<String> jiraLinks = new ArrayList<String>();
    for(int i =0; i < ticketNumbers.size(); i++) {
      def jira_json = "/usr/bin/curl -o /dev/null -X GET -H Content-Type: application/json --cert-type PEM --key-type PEM -E /Users/Jenkins/.jenkins/workspace/certificates/cert.pem --key /Users/Jenkins/.jenkins/workspace/certificates/cert.pem https://jira.dev.org.co.uk:443/rest/api/2/issue/MYSTATS-2695".execute().text;
      def json = jsonParse(jira_json);
      def summary = json['fields']['summary'].toString();
    jiraLinks.add("[" + ticketNumbers[i] + "](https://jira.dev.org.co.uk/browse/" + ticketNumbers[i] + ")" + " - " + summary);
    }
    return jiraLinks;
  }

}
return new Helpers();

作为我 Jenkins 构建的一部分，我有

def groovyMethod = load("${env.WORKSPACE}/groovy_scripts/release_pipeline.groovy")
def jira = groovyMethod.createJiraLinks(ticketNumberCommits);
echo "JIRA LINKAS ARE $jira"
// $jira is always returned as empty string

我是否误解了这里的任何内容，因为我预计这会起作用？但似乎 curl 请求永远不会得到任何回报

谢谢

groovy String.execute() 返回可能仍在运行的进程（取决于系统负载和天气））

如果您想等到进程结束，请执行以下操作：

def txt = "cmd /c dir c:\\".execute().with{
    def output = new StringWriter()
    def error = new StringWriter()
    //wait for process ended and catch stderr and stdout 
    it.waitForProcessOutput(output, error)
    //check there is no error
    assert error.toString().size()==0: "$error"
    //println it.exitValue() //we can do check with error code
    //return stdout from closure 
    return output.toString()
}

为jenkins pipeline避免错误，请java.io.NotSerializableException使用以下代码：

node {
    def res = runAndWait("cmd /c dir c:\\")
    echo res
}

@NonCPS
String runAndWait(Object cmd){
    def proc = cmd.execute()
    def output = new StringWriter()
    def error = new StringWriter()
    //wait for process ended and catch stderr and stdout 
    proc.waitForProcessOutput(output, error)
    //check there is no error
    assert error.toString().trim().size()==0: "$error"
    //assert proc.exitValue()==0 //we can do check with error code
    //return stdout from closure 
    return output.toString()
}
