一、初级版：修改一个参数的默认值

需求：把t1项目的DB_TYPE的默认值从mysql改为oracle

代码

import jenkins
from xml.etree import ElementTree as ET
from xml.dom.minidom import parse

jenkins_server_url = "http://192.168.1.2:8080/"
username = "admin"
token = "111111"

server = jenkins.Jenkins(jenkins_server_url, username=username, password=token)
print(server.get_version())     # Jenkins版本

# 获取Jenkins job t1项目的配置文件
pipelineBuildConf = server.get_job_config('t1')
xml_root = ET.XML(pipelineBuildConf)                # 获取根标签
tree = ET.ElementTree(xml_root)
tree.write("config.xml", encoding="utf-8",short_empty_elements=True)    # 将配置文件保存到config.xml

# 处理config.xml
doc = parse("./config.xml")

# 删除字符串参数的某个元素
str_param_define=doc.getElementsByTagName("hudson.model.StringParameterDefinition")[0]
element_delete = doc.getElementsByTagName("defaultValue").item(0)
str_param_define.removeChild(element_delete)
# 创建该元素
str_param_define=doc.getElementsByTagName("hudson.model.StringParameterDefinition")[0]
new_element=doc.createElement("defaultValue")
new_element.appendChild(doc.createTextNode("oracle"))      # 给元素增加文本
str_param_define.appendChild(new_element)

with open("config.xml", "w", encoding="utf-8") as f:
    doc.writexml(f, indent='\n', addindent='\t', newl='\n', encoding="utf-8")

# 删除xml文件里面的空行
with open("config.xml","r",encoding="utf-8") as xmlfile:
    lines = [line for line in xmlfile if line.strip() != ""]
with open("config.xml", "w",encoding="utf-8") as xmlfile:
    xmlfile.writelines(lines)

f = open('config.xml', 'r',encoding="utf-8")     # 打开文件
xml = f.read()                                   # 读取文件内容
f.close()
server.reconfig_job("t1",xml)                    # 更新Job

效果

二、中级版：同时修改多个参数的默认值

需求：把t1项目的DB_TYPE改为oracle，OS_TYPE改为windows
