Jenkins export and import Job Pipeline

Jenkins Web page can be manually modify Job Pipeline 配置 ,But large quantities when a change is more troublesome.There are several kinds of batch modification method：
- 到 jenkins_home 安装目录下,执行 zip -r jobs.zip jobs/*/config.xml ,可以导出 Job 配置文件.不过修改了之后,需要重启 Jenkins 才会生效.
- 通过 Jenkins API 导出、导入 Job 配置文件.

In this paper, we give the second method Python 示例代码：

""" - The script is used for export、导入 Jenkins 的 Pipeline 脚本,保存为 XML 文件 - 需要安装 pip install jenkinsapi - Import the configuration file contains the ASCII 码时,需要修改 update_config() 的定义代码,注释 config = str(config) 一行 """

        with open(config_file, 'w', encoding='utf-8') as f:
