功能介绍
- 使用python urllib模块，请求saltstack api
- 针对saltstack api常用模块编写为函数，方便使用
- saltstack api配置简单化
注意事项
- 请保证自己的saltstack api是可以使用的，请在自己的salt服务器中使用以下命令
curl -k https://172.28.5.190:8000/login \
-H "Accept: application/x-yaml" \
-d username='saltapi' \
-d password='saltapi' \
-d eauth='pam'
- 执行正常结果，主要是需要token
return:
- eauth: pam
expire: 1542725811.402969
perms:
- .*
- '@wheel'
- '@runner'
start: 1542682611.402966
token: 541d1b86d29daaff1c1cbb8f01a454de0bf4cba3
