Gitlab触发jenkins并获取项目post参数

 

jenkins -- Generic Webhook Trigger插件

此插件是git webhook的高阶应用，安装后会暴露出来一个公共API，GWT插件接收到 JSON 或 XML 的 HTTP POST 请求后，根据我们配置的规则决定触发哪个Jenkins项目。
定义需要的变量

---

此插件有两种配置方式

1.图形界面配置-创建流水线任务在触发器中配置（本文不采用此法）

2.pipeline 脚本中配置-注意此方法需要手动触发一次构建任务生成 Generic Webhook Trigger配置

jenkins配置

1.安装插件

勾选Generic Webhook Trigger后，点击【Install without restart】安装插件。

2.创建Jenkins任务

在Jenkins Dashboard中，点击【新建任务】

输入任务名称，选择流水线类型后，点击确定创建任务。

 

 

点击刚才创建好的任务。

 

 

点击【配置】。

 

 

选择【流水线】。

3.pipeline内容

pipeline {
    agent any
    riggers{
        GenericTrigger(
            genericVariables:[
                [key:'event_name',value:'$.event_name'],   //触发动作  pubat or tag_pubat
                [key:'user_email',value:'$.user_email'],   //GitLab公共邮箱需要自行配置否则获取不到
                [key:'project_name',value:'$.project.name'],      //项目名称 DevOps_Test
                [key:'git_url',value:'$.project.git_http_url'],    //git_url http://xxx.xxx.xxx/devops/DevOps_Test.git
                [key:'ref',value:'$.ref'],                 //分支或tag信息
                [key:'group_name',value:'$.project.namespace'], //GITLAB_GROUP
                [key:'commits_id',value:'$.commits[0].id'] //gitlab commits id
            ],
            token:"qazwsx",   //gitlab webhook触发token 多个任务配置同一个token会一起触发
            causeString:'Triggered on $ref',
            printContributedVariables:true,
            printPostContent:true
        )
    }

    stages {
        stage('Hello') {
            steps {
                echo 'Hello World'
            }
        }
    }
}
