DEVOPS技术实践_22：根据参数传入条件控制执行不同stage

前面学习了参数的传递和调用，下面研究一下根据参数作为条件执行不同的stage

使用叫when 和expression控制某一个stage的运行，

运行场景例如写了多个stage，这个pipeline脚本执行执行冒烟测试，和集成测试。有时候，希望快速执行冒烟测试，想根据结果看看，不一定一上来就执行集成测试。为了达到这种控制效果，我们就需要使用逻辑控制。在pipeline中就使用when 和expression两个命令。例如，如果json文件中冒烟测试变量为true，我就只执行冒烟测试的stage,其他和冒烟测试无关的stage我就不去执行。如果冒烟测试变量值为false，也就是默认要跑集成测试（不跑冒烟测试）。下面分两个类型测试就好

1 修改json文件

{
"NAME":"Lucy",
"AGE":"18",
"PHONE_NUMBER":"13912345678",
"ADDRESS":"Haidian Beijing",
"EMAIL":"lucy@demo.com",
"GENDER":"male",
"SMOKE":"false"，
"IS_MARRY":"false"
}

test.json文件基础上加了一个变量 SMOKE，默认值是false。

2 使用的jenkinsfile文件

 import hudson.model.*;
    pipeline{
    agent any
    environment {
    INPUT_JSON = "/tmp/test.json"
    }
    stages{
        stage("Hello Pipeline") {
            steps {
                script {
                    println "Hello Pipeline!"
                    println env.JOB_NAME
                    println env.BUILD_NUMBER
                }
            }
        }
 
    stage("Init paramters in json") {
        steps {
            script {
 
                println "read josn input file"
                    json_file = INPUT_JSON? INPUT_JSON.trim() : ""
                    prop = readJSON file : json_file
                    name = prop.NAME? prop.NAME.trim() : ""
                    println "Name:" + name
                    age = prop.AGE? prop.AGE.trim() : ""
                    println "Age:" + age
                    phone = prop.PHONE_NUMBER? prop.PHONE_NUMBER.trim() : ""
                    println "Phone:" + phone
                    address = prop.ADDRESS? prop.ADDRESS.trim() : ""
                    println "Address:" + address
                    email = prop.EMAIL? prop.EMAIL.trim() : ""
                    println "Email:" + email
                    gender = prop.GENDER? prop.GENDER.trim() : ""
                    println "Gender:" + gender
                    is_marry = prop.IS_MARRY? prop.IS_MARRY.trim() : false
                    println "is_marry:" + is_marry
                    is_smoke = prop.SMOKE? prop.SMOKE : false
                    println "is_smoke:" + is_smoke
                }
            }
        }
    stage("call a method") {
            steps {
                script {
                    println "send the parameter as map type"
                    model_call = load env.JENKINS_HOME + "/moodlegroovy/model.groovy"
                    model_call.getUserInfo(name:name, age:age, phone:phone, address:address, email:email, gender:gender, is_marry:is_marry)
                }
            }
        }
        stage("check serive up") {
            when {
                expression { return  ("$is_smoke" == "true")}
            }
            steps {
                script {
                    println "SMOKE TEST: check service startup"
                }
            }
        }

        stage("check UI login") {
            when {
                expression {
                    return ("$is_smoke" == "true")
                }
            }
            steps {
                script {
                    println "SMOKE TEST: check UI login success"
                }
            }
        }
        
        stage("Integrate-ModelA") {
            when {
                expression {
                    return ("$is_smoke" == "false")
                }
            }
            steps {
                script {
                    println "Integrate-ModelA"
                }
            }
        }
        
        stage("Integrate-ModelB") {
            when {
                expression {
                    return ("$is_smoke" == "false")
                }
            }
            steps {
                script {
                    println "Integrate-ModelB"
                }
            }
        }
     }
}

4 修改json文件，把smoke的值改为true

{
"NAME":"Lucy",
"AGE":"18",
"PHONE_NUMBER":"13912345678",
"ADDRESS":"Haidian Beijing",
"EMAIL":"lucy@demo.com",
"GENDER":"male",
"SMOKE":"false",
"IS_MARRY":"false"
}

5 点击构建测试

在最后的的两个false没有输出，true输出
