核心参数生成说明

以下MD5默认为HEX小写

AppList

User.app_list字段

Android 请直接传输PackageName, 英文逗号分隔

iOS请基于Queried URL Schemes使用UIKit.UIApplication.canOpenURL进行探查后，映射为BundleId，英文逗号分隔后传输

请注意，iOS15后仅允许最多50个item设置在Info.plist中

iOS: PAID_1_3

PAID = MD5(启动时间 + ":" + 更新时间)

eg: 启动时间 1608950797 更新时间 1600326333.862857 PAID_1_3 b0dd8df5ee995862e42f4a922c7de25a

iOS: PAID_1_4

PAID_1_4 = MD5(设备初始化时间) + "-" + MD5(系统更新时间) + "-" + MD5(系统启动时间)
