来自命令行和 Groovy 脚本的 curl 请求 [英] Curl request from command line and via Groovy script

问题描述

我遇到了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

I am facing an issue which i do not understand, I have written a simple groovy script that when called from the command line works as expected

#!/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}"

所以当我做 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]

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

What i then have is a groovy script which i call as part of a jenkins pipeline build

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();

作为我的 Jenkins 构建的一部分，我有

As part of my Jenkins build i have

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，因为我期望这会起作用?但似乎 curl 请求永远不会得到任何回报

Am i misunderstanding anything here as i would have expected this to work? but it seems as if the curl request never gets anything back

谢谢

推荐答案

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

groovy String.execute() returns Process that could be still running (depends on system load and weather))

如果您想等到进程结束，请执行以下操作:

if you want to wait until process ended do like this:

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()
}

对于jenkins pipeline 避免错误java.io.NotSerializableException使用以下代码:

for jenkins pipeline to avoid error java.io.NotSerializableException use the following code:

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()
}
