在上一篇学习了把参数写进Json文件，然后通过去Json文件，调用参数的方法
调用的方法是通过一个三元运算符实现的
gender = prop.GENDER? prop.GENDER.trim() : "" is_marry = prop.IS_MARRY? prop.IS_MARRY.trim() : false
这种写法就是Java中三元运算符的写法，prop.GENDER?表示判断这个变量是否存在，如果存在我们就prop.GENDER.trim(), 如果不存在，我们设置默认值为空字符串。上面函的数trim()，就是去除变量值的前后的多余空格，这个写法还是很严谨，我们不可能保证用户就不一定带着多余空格进来。其实在groovy语法中，还有简写版的三元运算符：
GENDER = prop.GENDER?: "default"
上面意思还是一样，只不过是更加符合groovy的风格，意思性别字段存在吗，如果存在就是里面的值，如果不存在，就设置default这个值。这个缺点就是无法直接trim()，去除前后空格。
下面学习使用map方式传递参数
[root@node1 ~]# mkdir /root/.jenkins/moodlegroovy
[root@node1 ~]# vi /root/.jenkins/moodlegroovy/model.groovy
def getUserInfo(args) { def name = args.name def age = args.age def phone = args.phone def address = args.address def email = args.email def gender = args.gender def is_marry = args.is_marry // she or he def binge = (gender == "male")? "he" : "she" // if is marry def marry = (is_marry == true)? "is marry" : "is not marry yet" def userInfo = """ ${name} come from ${address}, ${binge} is ${age} old. ${binge}‘s phone number is ${phone}, or you can contact ${binge} via ${email}, ${binge} ${marry}. """ println userInfo } return this;
在这里使用def重新定义了两个参数（bing和marry）
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 } } } 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) } } } } }

构建成功，也按照原有方式传递进来
总结，上面模块方法的时候参数就写了一个args, 调用方法的时候传了7个map对象进去。然后模块方法中每个变量前面都加上def, 加上之后模块中的变量都变成了局部变量。这样和已经存在内存中的stage里面的全局变量不会被覆盖和重写
假如不适用三元运算符调用json文件的参数，但是依然把这个参数传递到model.groovy里
删掉：is_marry参数
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 } } } 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) } } } } }
点击构建，则会报错，没有这个参数
加上这个参数，但是不传递到model.groovy中
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 } } } 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,gender:gender, is_marry:is_marry)
}
}
}
}
