        {"signature": "xxxxxxxxx"}, //请求验证加密签名(非彩信签名)；
签名生成方式：
仅公共参数以ASCII码从小到大排序值，key=value，多值以“&”隔开，拼接之后md5 32位小写； 如：md5(api_id=xxxx&api_key=xxxx&request_id=xxxxxxxx&timestamp=xxxxxxx)
APIKEY(用户中心【富媒体短信】-【5G视频短信】-【产品总览】查看)
2、动态密码(生成动态密码方式请看该文档末尾的说明)
        {"timestamp": 1623643787}, //东八时区;10位时间戳，时间允许相差±60S
        {"request_id": "xxxxxxxxxxxx"}, //请求方请求ID，建议使用唯一ID，比如使用uuid；我方系统会2小时内去重验证处理，防止网络重复攻击；
        {"product_id": 1001}, //产品ID
