Jenkins Generic Webhook 实践优化 获取提交信息

之前gitlab和Jenkins已经集成好了，现在需要来解析一些数据，因为提交构建需要有些值去拿的。

 比如可以获取谁提交的，哪个分支提交的，用户Email和commitid。

"user_username": "root"
"ref": "refs/heads/master"
 "user_email": ""
"checkout_sha": "1d6ed28d4536ce9313e57b47a821753333aab1da"
           

webHookData = readJSON text: "${webHookData}"
userName = webHookData["user_username"]
userEmail = webHookData["user_email"]
branchName = webHookData["ref"] - "refs/heads/"
commitID = webHookData["checkout_sha"]

currentBuild.displayName = commitID
currentBuild.description = "Trigger by user ${userName} \n branch: ${branchName}"


pipeline {
    agent any

    stages {
        stage('resdJson') {
            steps {
                println("the user name is ${userName}")
                println("the trigger branch name is ${branchName}")
                println("the user email is ${userEmail}")
                
            }
        }
    }
}



[Pipeline] readJSON
[Pipeline] node
Running on build-01 in /data/cicd/jenkinsagent/workspace/Gitlab-Webhook-Trigger
[Pipeline] {
[Pipeline] stage
[Pipeline] { (resdJson)
[Pipeline] echo
the user name is root
[Pipeline] echo
the trigger branch name is master
[Pipeline] echo
the user email is 
[Pipeline] }
[Pipeline] // stage

一个动态传递分支参数的示例： 

首先，Jenkins触发器中配置一个request参数，

runOpts

作为构建类型判断。

 第二步， Gitlab webhook中指定此参数。

第三步， 构建测试。

/*
支持自动构建和手动构建：
1. 在触发添加了一个request参数  runOpts 
2. Gitlab webhook中添加runOpts参数=gitlab
3. JenkinsPipeline 根据runOpts值进行运行

*/
//gitlab触发
try {
    if ( "${runOpts}" == "gitlab"){
        //自动
        // 操作webhook数据
        println("${WebHookData}")
        webHookData = readJSON text: "${WebHookData}"
        env.userName = webHookData["user_username"]
        env.userEmail = webHookData["user_email"]
        env.branchName = webHookData["ref"] - "refs/heads/"
        env.srcUrl = webHookData["project"]["git_http_url"]
        env.commitID = webHookData["checkout_sha"]
        currentBuild.description = "Trigger by user ${env.userName} \n branch: ${env.branchName}"
        currentBuild.displayName = env.commitID
    } 
} catch(e){
    println(e)
    env.userEmail = "[email protected]"
    currentBuild.description ="Trigger by 手动触发 \n branch: ${env.branchName}"

}
           

try

 语句块中的是解析Gitlab传递过来的数据的，然后将

checkout

 中的分支字符串和仓库地址使用变量替换。

branchName

 和

srcUrl

 都是解析的Gitlab hook数据。

添加

try

 语句块的目的也是为了忽略这些错误的， 因为手动触发是拿不到gitlab 传递的数据的，这是两种不同的触发方式所以一定要注意。 所以最后我们在UI定义两个参数作为手动触发使用的。

效果：
