一、缘 起
最近学习【悠悠课堂】的接口自动化教程,文中提到Requests发送带cookies请求的方法,笔者随之也将其用于手头实际项目中,大致如下
二、背 景
实际需求是监控平台侧下发消息有无异常,如有异常便触发报警推送邮件,项目中下发消息接口需要带cookies
三、说 明
脚本的工程名为ynJxhdSendMsg,大致结构如下图
- sendMsg.py为主程序,函数checkMsg为在已发消息列表中查找已下发消息,函数sendMsg为发消息并根据结果返回对应的标识
- sendAlertEmail.py为发送邮件程序,在sendMsg.py中根据不同标识调用sendAlertEmail.py下的send_alert_email函数发报警邮件
四、实 现
【重点】发请求之前先加载cookies,方法如下
~ ...... ~ # 加载cookies # 第一步,引入RequestsCookieJar() coo = requests.cookies.RequestsCookieJar() # 第二步,设置cookies参数,coo.set('key', 'value') coo.set('__utma', '82342229.1946326147.***.1545556722.1545556733.4') coo.set('JSESSIONID', 'D898010550***ADB0600BF31FF') # 第三步,引入seeeion(),并update sess = requests.session() sess.cookies.update(coo) ~ ...... ~
sendMsg.py
- 发送带当前时间戳的特定消息,在发送成功后便于通过时间戳检索
- 函数checkMsg为在已发消息列表中查找已下发消息
- 函数sendMsg为发消息并根据结果返回对应的标识
- 导入sendAlertEmail模块的send_alert_email方法,在sendMsg.py中根据不同标识调用send_alert_email函数发报警邮件

sendAlertEmail.py,方法较常见,此处略
五、最 后
完成以上,将脚本放在jenkins上定时构建,即可实现实时监控平台侧消息下发情况并及时反馈报警邮件的需求
