python(10)实践Django-jenkins

目的：通过访问Jenkins得到各个项目的构建状态。

jenkins是一款持续集成的工具，插件众多，配置简单，跨平台。

1. 使用python和jenkins的依赖包
   pip install python-jenkins

2. jenkins连接配置

    import jenkins
    jenkins_url = 'http://ip:port'
    jenkins_user = ''
    jenkins_passwd = ''
    jen = jenkins.Jenkins(jenkins_url, username=jenkins_user, password=jenkins_passwd)
    #实例化jenkins对象，然后使用jenkins对象做各种操作。
   

3. 常用
   可参考 http://python-jenkins.readthedocs.io/en/latest/

查询某job_name的最后一次构建信息

 lastBuild_Number = jen.get_job_info(job_name)['lastBuild']['number']
 lastBuild_url = jen.get_build_info(job_name, lastBuild_Number)['url']# 最后一次build号
 times = jen.get_build_info(job_name, lastBuild_Number)['timestamp']# build的日期
 result = jen.get_build_info(job_name, lastBuild_Number)['result']

得到项目scm是git还是svn

job_info_scm = jen.get_job_info(job_name)['scm']['_class']
#{'_class': 'hudson.plugins.git.GitSCM'}
if job_info_scm.find('git') != -1:
     pci.pro_scm = 'git'
else:
    pci.pro_scm = 'svn'

根据job_name 和 build_number更新构建状态

times = jen.get_build_info(job_name, build_number)['timestamp']
# build的日期
result = jen.get_build_info(job_name, build_number)['result']

获取jenkins中已有构建的tag信息
默认情况下是拿不到tag的信息，需修改jenkins的init.py 中方法
def get_build_info(self, name, number, depth=2):

#因我们只对构建成功的打tag
if result == 'SUCCESS':
     if pci.pro_scm == 'git':
         if jen.get_build_info(job_name, build_number)['actions'][2]['tags']:
            tags = jen.get_build_info(job_name, build_number)['actions'][2]['tags'][0]['tag']
            pci_build.build_tags = tags
            logger.info('update_pci_build_by_jenkins' + 'job_name' + job_name + 'tags:' +  tags)
     else:
         if jen.get_build_info(job_name, build_number)['actions'][1]['tags']:
             tags = jen.get_build_info(job_name, build_number)['actions'][1]['tags'][0]['url']
             pci_build.build_tags = tags
             logger.info('update_pci_build_by_jenkins' + 'job_name' + job_name + 'tags:' + tags)
