我有一个脚本可以使用令牌远程触发 Jenkins 上的作业。这是我的脚本：

JENKINS_URL='http://jenkins.myserver.com/jenkins'
JOB_NAME='job/utilities/job/my_job'
JOB_TOKEN='my_token'

curl "${JENKINS_URL}/${JOB_NAME}/buildWithParameters?token=${JOB_TOKEN}"

运行后，我得到以下响应：

* Hostname was NOT found in DNS cache
*   Trying 10.5.187.225...
* Connected to jenkins.myserver.com (10.5.187.225) port 80 (#0)

我注意到它在标题中返回队列 url：http://jenkins.myserver.com/jenkins/queue/item/91。但我不知道我应该如何使用这个返回 url。

1) 我想知道是否有人知道我如何检查我刚刚创建的工作的状态？

2）由于上面的响应没有返回作业#，我不能真正使用这个api调用：

curl http://jenkins.myserver.com/jenkins/job/utilities/job/my_job/8/api/json

检查状态。那么，从上述响应中获取位置 url 后，我在哪里可以获得职位名称和职位编号？

谢谢

我使用轮询 Jenkins 服务器解决了这个问题。远程启动作业时，返回标头具有作业队列 URL。使用这个可以进行更多的 API 调用来获取状态。

脚步：

  • 开始工作
  • 解析返回“位置”标头
  • 轮询队列寻找工作开始
    • 作业队列条目一旦启动，其 json 或 xml 中将有一个带有作业编号的“可执行”条目
  • 轮询等待结果的作业状态

我使用 python 和 Requests 模块来做到这一点

#!/usr/bin/python

import requests
import re
import sys 
import json
import time

# secs for polling Jenkins API
#
QUEUE_POLL_INTERVAL = 2 
JOB_POLL_INTERVAL = 20
OVERALL_TIMEOUT = 3600 # 1 hour

# job specifics: should be passed in
auth_token = 'buildmaster:173223588624f980c3AAA68d4d8efe0c'
jenkins_uri = '192.168.115.187:8080'
job_name = 'rf_systest'
build_token = 'rf_systest_auth_token'

# start the build
#
start_build_url = 'http://{}@{}/job/{}/build?token={}'.format(
        auth_token, jenkins_uri, job_name, build_token)
r = requests.post(start_build_url)

# from return headers get job queue location
#
m = re.match(r"http.+(queue.+)\/", r.headers['Location'])
if not m:
    # To Do: handle error
    print "Job starte request did not have queue location"
    sys.exit(1)

# poll the queue looking for job to start
#
queue_id = m.group(1)
job_info_url = 'http://{}@{}/{}/api/json'.format(auth_token, jenkins_uri, queue_id)
elasped_time = 0 
print '{} Job {} added to queue: {}'.format(time.ctime(), job_name, job_info_url)
while True:
    l = requests.get(job_info_url)
    jqe = l.json()
    task = jqe['task']['name']
    try:
        job_id = jqe['executable']['number']
        break
    except:
        #print "no job ID yet for build: {}".format(task)
        time.sleep(QUEUE_POLL_INTERVAL)
        elasped_time += QUEUE_POLL_INTERVAL

    if (elasped_time % (QUEUE_POLL_INTERVAL * 10)) == 0:
        print "{}: Job {} not started yet from {}".format(time.ctime(), job_name, queue_id)

# poll job status waiting for a result
#
job_url = 'http://{}@{}/job/{}/{}/api/json'.format(auth_token, jenkins_uri, job_name, job_id)
start_epoch = int(time.time())
while True:
    print "{}: Job started URL: {}".format(time.ctime(), job_url)
    j = requests.get(job_url)
    jje = j.json()
    result = jje['result']
    if result == 'SUCCESS':
        # Do success steps
        print "{}: Job: {} Status: {}".format(time.ctime(), job_name, result)
        break
    elif result == 'FAILURE':
        # Do failure steps
        print "{}: Job: {} Status: {}".format(time.ctime(), job_name, result)
        break
    elif result == 'ABORTED':
        # Do aborted steps
        print "{}: Job: {} Status: {}".format(time.ctime(), job_name, result)
        break
    else:
        print "{}: Job: {} Status: {}. Polling again in {} secs".format(
                time.ctime(), job_name, result, JOB_POLL_INTERVAL)

    cur_epoch = int(time.time())
    if (cur_epoch - start_epoch) > OVERALL_TIMEOUT:
        print "{}: No status before timeout of {} secs".format(OVERALL_TIMEOUT)
        sys.exit(1)

    time.sleep(JOB_POLL_INTERVAL)

输出：

我有类似的问题，只能通过 rest api 来获取状态。
这是我的解决方案（这是一个弱且不稳定的解决方案！）： 

#Ex. http://jenkins.com/job/test
JOB_URL="${JENKINS_URL}/job/${JOB_NAME}"

#here you can ask for next build job number
function getNextBuildNr(){
  curl --silent ${JOB_URL}/api/json | grep -Po '"nextBuildNumber":\K\d+'
}    

# this will request the Status of job
function getBuildState(){
  buildNr=$1
  curl --silent ${JOB_URL}/${buildNr}/api/json | grep -Po '"result":\s*"\K\w+'
}

#this will wait for your Job state, by polling Jenkins every second
function waitForJob() {
  buildNr=$1
  state=""

  while [ "${state}" == "" ]
  do
     sleep 1
     state=$(getBuildState ${buildNr})
     echo -n '.'
  done

  echo -e "\n"
}

#now you can run and build
BUILD_NR=$(getNextBuildNr)

# input here your code/function to trigger the job

waitForJob ${BUILD_NR}
BUILD_STATE=$(getBuildState ${BUILD_NR})
echo "$BUILD_STATE"

您可以为此使用 Jenkins API。示例 Python 脚本：

import json
import requests
import time



job_name = "testjob" .  #Give your job name here


def jenkins_job_status(job_name):

        try:
                url  = "https://your_jenkins_endpoint/job/%s/lastBuild/api/json" %job_name   #Replace 'your_jenkins_endpoint' with your Jenkins URL
                while True:
                        data = requests.get(url).json()
                        if data['building']:
                                time.sleep(60)
                        else:
                                if data['result'] == "SUCCESS":

                                        print "Job is success"
                                        return True
                                else:
                                        print "Job status failed"
                                        return False


        except Exception as e:
                print str(e)
                return False




if __name__ == "__main__":

        if jenkins_job_status(job_name):

                print "Put your autmation here for 'job is success' condition"

        else:
                print "Put your autmation here for 'job is failed' condition"

当您触发一个作业时，该作业将被放入队列中。实际构建仅在它开始运行时创建，此时构建会获得一个构建号。如果您的所有执行程序都很忙，有时可能需要很长时间才能创建构建并开始运行。

触发作业时获取内部版本号的唯一方法是使用Jenkins CLI的“构建”命令。如果您使用 -w 选项，该命令将在构建开始之前不会返回，然后它将打印“Started build #N”

您实际上不需要 java cli.jar，只需一个 ssh 客户端就足够了。见https://wiki.jenkins-ci.org/display/JENKINS/Jenkins+SSH

除此之外，没有已知的解决方案。您可能能够搜索构建并找到一个在您触发工作时触发的构建，但这是很多工作。

对于需要从另一个 Jenkins 触发远程 Jenkins 作业的人来说，这是一个很好的解决方案，它允许触发远程作业并检查其状态：https ://github.com/jenkinsci/parameterized-remote-trigger-plugin/ blob/master/README_PipelineConfiguration.md

它是如此简单：

def handle = triggerRemoteJob job: 'https://myjenkins:8080/job/JobWithoutParams', auth: TokenAuth(apiToken: '<theApiToken>', userName: '<userName>'), parameters: 'param1=abc\nparam2=xyz'

一个完全启用 groovy 的解决方案将类似于以下内容：

 import groovy.json.JsonSlurper



    while(true){
            sh """
                   curl -X POST -u "admin:xxx" "https://another-jenkins.com/job/jobName/build"
               """

               def response = sh(script: """ curl -X GET -u "admin:xxx" "https://another-jenkins.com/job/jobName/lastBuild/api/json" """, returnStdout: true)

               def jsonSlurper = new JsonSlurper()
               def obj = jsonSlurper.parseText(response)

               if (!obj.building){

                   if(obj.result=="FAILURE"){
                    println("remote jenkins failing")
                       //throw new Exception("QA JENKINS returns failure.")
                   }
                   break;
               }
                
                sleep(3000)
       }
