python实现监控阿里云账户余额功能

背景

由于阿里云oss，cdn消耗钱的速度比较快，在不知道的情况下，服务就被停了，影响比较大。所以想做个监控。百度一下阿里云账户余额 api 还真有；于是开启了踩坑之路。

查阅资料创建accessKeyId和accessKeySecret

• 官方文档(感觉并不细致) https://help.aliyun.com/document_detail/87997.html?spm=a2c6h.13066369.0.0.59e4581eaxXH1O
• sdk https://developer.aliyun.com/sdk?spm=5176.12818093.resource-links.dsdk_platform.488716d022QXo0
• 看了官方文档后还是有点懵逼，后面Google了这个关键字QueryAccountBalanceRequest才看到真正的样例代码https://developer.aliyun.com/ask/132002(感觉这块资料很少呀，aliyun-python-sdk-bssopenapi居然没写在sdk安装列表里面，在社区找到的)。
• 创建accessKeyId，鼠标悬停到右上角

撸码阶段

要安装的依赖

sudo pip install aliyun-python-sdk-core  -i https://mirrors.aliyun.com/pypi/simple/
sudo pip install  aliyun-python-sdk-bssopenapi -i https://mirrors.aliyun.com/pypi/simple/

from aliyunsdkcore import client
from aliyunsdkbssopenapi.request.v20171214 import QueryAccountBalanceRequest
from aliyunsdkcore.profile import region_provider
# 检查账户余额
def check_account(name, accessKeyId, accessKeySecret, valve, notify_emails):
  region_provider.add_endpoint('BssOpenApi', 'cn-hangzhou', 'business.aliyuncs.com')
  clt = client.AcsClient(accessKeyId, accessKeySecret, 'cn-hangzhou')
  request = QueryAccountBalanceRequest.QueryAccountBalanceRequest()
  request.set_accept_format("JSON")
  result = clt.do_action_with_exception(request)
  print(result)

下面是我封装的检查账户余额，如果低于阀值就给要通知的人发邮件。 monitor_balance.py

• 还有个json文件配置monitor.json
• 里面分别代表的是名称，发起邮件通知账户余额阀值，id，密钥，通知的邮箱(可以多个，逗号,分割)。

[{"name":"恭喜你888","valve": "100","accessKeyId":"xxx","accessKeySecret":"xxx","notifyEmail":1030907690@qq.com}]

运行效果

如果是正式环境部署的话可以用这个命令,可以后台运行，日志输出到 nohup.out:

nohup python -u monitor_balance.py > nohup.out 2>&1 &
