51工具盒子前言 {#前言}
之前有一篇文章就是写了钉钉获取朋友圈执行日志的文章，然后我就在想：我的博客是静态网站，每次需要去刷新CDN，我可不可以去实现一个提交代码后就自动刷新CDN的问题
想法 {#想法}
我一开始的想法是：部署成功后就发生消息给钉钉机器人 然后钉钉机器人收到消息就自动去刷新CDN。但是由于限制，导致我没有去实现。后面看到飞书的，然后发现它的自定义机器人一样有限制。所以我就改成了去监控CDN的使用情况。效果图如下
获取自定义机器人 {#获取自定义机器人}
在群主中选择设置
在右侧 设置 界面，点击 群机器人
- 在 群机器人 界面点击 添加机器人。
- 在 添加机器人 对话框，找到并点击 自定义机器人
自定义机器人头像、昵称、描述 并点击 添加
获取到机器人的webhook地址 保存好webhook 和 签名密钥 并点击 完成
这里要选择签名校验
获取腾讯CDN {#获取腾讯CDN}
开发 需要先下载腾讯SDK库
|---------------------------------------------------------------------------------------------------|
| pip install -i https://mirrors.tencent.com/pypi/simple/ --upgrade tencentcloud-sdk-python |
这里需要提供 腾讯云API密钥 和 边缘加速CDN的ID
|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

填入腾讯云密钥
|-----------------------------------------------------|
| cred = credential.Credential( "密钥" , "密钥" ) |
填入CDN的ID 这里只需要修改 ZoneIds
|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| params = { "StartTime" : start_of_day_iso, "EndTime" : end_of_day_iso, "MetricNames" : [ "l7Flow_outFlux" , "l7Flow_inFlux" , "l7Flow_request" ], "ZoneIds" : [ "CDN ID" ], "Interval" : "day" , "Area" : "mainland" } |

修改密钥 dogecloud_api 方法中修改
|--------------------------------------------------|
| access_key = 'xxxxx' secret_key = 'xxxx' |
修改域名 Get_traffic 和 Get_reuestcount 方法里面的 domains ，把里面的内容改成现有在CDN部署的域名
|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| api = dogecloud_api( '/cdn/stat/request.json' , { 'rtype' : 'path' , 'start_date' : formatted_date, 'end_date' : formatted_date, 'granularity' : 'day' , 'area' : 'china' , 'domains' : 'test.com' }) |
