【python_钉钉群发图片】

需求：

**在钉钉群发图片，需要以图片的形式展示，如图所示：**

但是目前影刀里面没有符合条件的指令

解决方法：

1、在钉钉开发者后台新建一个自建应用，发版，然后获取里面的appkey和appsecret，根据这两个参数调用API生成access_token，以提供给上传文件的接口试用。获取企业内部应用的access_token
2、调用上传临时素材的API，将本地图片上传，生成media_id。上传媒体文件
3、在内部群随便新建一个自定义的机器人。调用自定义机器人发送钉钉群通知的API，在请求路径里面需要有时间和签名，签名根据自定义机器人中的加签编码生成。请求体里面填markdown的形式，然后将图片的media_id写进去。自定义机器人发送群消息

# 使用提醒:
# 1. xbot包提供软件自动化、数据表格、Excel、日志、AI等功能
# 2. package包提供访问当前应用数据的功能，如获取元素、访问全局变量、获取资源文件等功能
# 3. 当此模块作为流程独立运行时执行main函数
# 4. 可视化流程中可以通过"调用模块"的指令使用此模块import xbot
