## 正确写法 ##

import jenkins
    
    class JenkinsServer:
        _instance = None
        serverUrl = "http://192.168.100.101:8081"
        username = "admin"
        password = "api token授权令牌 不是密码"
    
        def __new__(cls):
            if not cls._instance:
                cls._instance = super().__new__(cls)
                cls._instance.server = jenkins.Jenkins(cls.serverUrl, cls.username, cls.password)
            return cls._instance
    
        def __getattr__(self, attr):
            return getattr(self._instance.server, attr)
    
    server = JenkinsServer()
    defProjectName = "jenkinsfile-gen-template"
    def create_a_job(newProjectName,scriptPath):
       if server.job_exists(newProjectName) == True :
          print("项目已存在，删除后重新创建!")
          server.delete_job(newProjectName)
       config_xml=server.get_job_config(defProjectName)
       new_config_xml = config_xml.replace("<scriptPath>devops/kjgh-test/web-KjghReact.groovy</scriptPath>","<scriptPath>{}</scriptPath>".format(scriptPath))
       print(new_config_xml)
       server.create_job(newProjectName,new_config_xml)
    
    def build_a_job(projectName):
        if server.job_exists(projectName) == True :
            server.build_job(projectName)
        else:
            print("项目不存在!")

## 获取API Token ##

## 错误示范 ##

> 下述代码不能保证`server`是单例的，每次请求都会创建一个实例

### 创建job ###

import jenkins
    
    #login
    serverUrl = "http://192.168.100.101:8081"
    username = "admin"
    password = "api token授权令牌 不是密码"
    server = jenkins.Jenkins(serverUrl,username,password)
    
    defProjectName = "jenkinsfile-gen-template"
    def create_a_job(newProjectName,scriptPath):
       if server.job_exists(newProjectName) == True :
          print("项目已存在，删除后重新创建!")
          server.delete_job(newProjectName)
       config_xml=server.get_job_config(defProjectName)
       new_config_xml = config_xml.replace("<scriptPath>devops/kjgh-test/web-KjghReact.groovy</scriptPath>","<scriptPath>{}</scriptPath>".format(scriptPath))
       print(new_config_xml)
       server.create_job(newProjectName,new_config_xml)

### 触发构建 ###

import jenkins
    
    # if __name__ == '__main__':
    #login
    serverUrl = "http://192.168.100.101:8081"
    username = "admin"
    password = "api token授权令牌 不是密码"
    server = jenkins.Jenkins(serverUrl,username,password)
    
    def build_a_job(projectName):
        if server.job_exists(projectName) == True :
            server.build_job(projectName)
        else:
            print("项目不存在!")
