如何从詹金斯上的 jfrog webhook 触发器获取有效负载信息

Question

我正在设置一个 jenkins 作业，每当在 jfrog 中部署工件时都会触发该作业。我已按照以下文档中的步骤进行操作，并且能够触发作业。但不幸的是，我无法获取变量值。我不确定如何查看我们在詹金斯上收到的有效负载侧拉所需的变量。

我的管道：

pipeline {
    agent any
    
    triggers {
        GenericTrigger(
            genericVariables: [
                [key: 'ARTIFACT_NAME', value: '$.artifactory.webhook.data.name'],
                [event: 'EVENT_NAME', value: '$.artifactory.webhook.event']
            ],
            causeString: 'Triggered on $ARTIFACT_NAME'
        )
    }

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

Answer 1

我做到了。我们必须在通用 webhook 触发器选项下的配置 jenkins 作业中启用打印帖子内容。完成后，它开始在控制台日志中显示 json 有效负载。之后，我们可以使用来自有效负载的 jsonpath 过滤器添加变量

Answer 2

我想建议使用Jenkins Artifactory plugin 的不同方法：

您可以在 UI 中配置构建触发器：

或者您可以在管道中配置构建触发器：

stages {
    stage('Artifactory configuration') {
        steps {
            rtServer(
                    id: "ARTIFACTORY_SERVER",
                    url: SERVER_URL,
                    credentialsId: CREDENTIALS
            )
        }
    }

    stage('Add build trigger') {
        steps {
            rtBuildTrigger(
                    serverId: "ARTIFACTORY_SERVER",
                    spec: "*/10 * * * *",
                    paths: "generic-libs-local/builds/starship"
            )
        }
    }
}

要获取 Artifactory 中导致触发器的路径，您可以执行以下操作：

environment {
    // The URL of the artifact in Artifactory, caused the job to be triggered.
    // May be empty if the build isn't triggered by a change in Artifactory.
    RT_TRIGGER_URL = "${currentBuild.getBuildCauses('org.jfrog.hudson.trigger.ArtifactoryCause')[0]?.url}"
}
