当一个接口需要将请求参数拼接并进行MD5加密后转换成大写生成sign验签，利用python请求方式实现验签加密并实现自动调用接口

1. 拼接规则： Secret + "appId" + appId + 'data' + str(str_data) + "timestamp" + MD5_sign().timetamp()
2. 密钥：
   appId = 433f96c852211a42b12b1111
   Secret = “d12717a5cf-3824e-422ca-9260a-88c124527103a341112”
3. 请求data需要作为先拼接后再进行MD5加密
4. 散列值最后转为"⼤写"赋给sign
