[0087] 请参阅图 8, 本发明提供一种 POS终端应用包的下载通讯方法, 包括以下步骤
[0088] POS终端向服务器发送握手字符, 服务器接收、 确认并向 POS终端发送应答字 符, 这样 POS终端与服务器就通过可靠握手过程建立起来了连接;
[0089] POS终端向服务器发送传输层参数信息, 服务器接收并根据自身信息发送参数 应答, 以此与 POS终端进行传输层参数的协商;
[0090] POS终端向服务器通过所述传输层分割发送终端信息包, 并通过传输层接口将 所述终端信息包传送至处于应用层的所述服务器的支付产品应用软件; [0091] 服务器向 POS终端通过所述传输层分割发送下载确认包, 并通过所述传输层接 口将所述下载确认包传送至处于所述应用层的所述 POS终端的应用程序。
[0092] 所述应用层通过判断所述传输层接口的返回值来进行对上一个数据包的合法性 检査。
[0093] 区别于现有技术只有一层应用方法, PC的支付产品应用软件和 POS终端的通讯 方法必须是一收一发机制, 除了第一个包外, 其余发送包都包含对上一个接收 包的合法性检査结果, 不合法的情况下发出的异常退出的通知, 这样, 既浪费 了吋间, 也增加了下载过程的复杂性。 本发明提供的 P0S终端应用包的下载通讯 方法, 分为两层: 传输层和应用层; 传输层根据设定的包大小, 对应用包进行 分割发送, 且保证每个分割包的可靠传输; 应用层收发数据通过传输层接口进 行操作, 通过判断传输层接口的返回值来进行对上一个数据包的合法性检査; 终端信息包之前的握手过程, 采用较低波特率进行可靠握手, 在传输层参数协 商完毕采用高速波特率进行通讯, 并且后续过程都基于传输层接口进行通讯。 这样使得功能简化、 流程更加清晰, 也节约了吋间。
[0094] 综上所述, 本发明区别于现有技术的下载过程不会检査 POS终端现有文件的版 本, 只能做默认更新, 若 POS终端上的驱动丢失 (被手动刪除) 或版本太低 (新 增接口或修复严重 bug吋, 要求应用必须使用最新版本的驱动) 的情况下, 无法 保证用户会将最新的驱动添加到下载列表中, 会导致使用过程中产生模块缺失 或接口调用故障, 本发明提供一种 POS终端应用包的下载方法, 通过使用更新下 载方法, 实现了待下载文件版本与 POS终端现有文件版本的比较, 同吋根据 POS 终端系统底层文件的版本需求对底层驱动进行自动更新升级, 简化、 加快了 POS 终端升级维护, 且保证升级后运行的更加可靠。
[0095] 此外, 刪除无效驱动方法经过对比 POS终端配置文件, 刪除 POS终端配置文件 外无效配置文件的模块驱动, 大大减少了手动刪除造成的必要驱动丢失率; 清 空 POS旧有应用程序方法, 将用户分区的所有文件刪除, 为用户节省了 POS终端 的存储区。
[0096] 此外, 本发明提供的另一个解决方案: POS终端应用包的下载通讯方法区别于 现有技术只有一层应用方法, PC的支付产品应用软件和 POS终端的通讯方法必 须是一收一发机制, 除了第一个包外, 其余发送包都包含对上一个接收包的合 法性检査结果, 不合法的情况下发出的异常退出的通知, 这样, 既浪费了吋间
, 也增加了下载过程的复杂性。 本发明提供的 POS终端应用包的下载通讯方法, 分为两层: 传输层和应用层; 传输层根据设定的包大小, 对应用包进行分割发 送, 且保证每个分割包的可靠传输; 应用层收发数据通过传输层接口进行操作 , 通过判断传输层接口的返回值来进行对上一个数据包的合法性检査; 终端信 息包之前的握手过程, 采用较低波特率进行可靠握手, 在传输层参数协商完毕 采用高速波特率进行通讯, 并且后续过程都基于传输层接口进行通讯。 这样使 得功能简化、 流程更加清晰, 也节约了吋间。
[0097] 综上所述, 区别于现有技术的下载过程不会检査 POS终端现有程序的版本, 只 能做默认更新, 若 POS终端上的驱动丢失 (被手动刪除) 或版本太低 (新增接口 或修复严重 bug吋, 要求应用必须使用最新版本的驱动) 的情况下, 无法保证用 户会将最新的驱动添加到下载列表中, 会导致使用过程中产生模块缺失或接口 调用故障, 本发明提供一种 POS终端应用包的下载方法、 装置及通讯方法, 用 P OS终端应用包下载方法的下载装置通过下载通讯方法完成 POS终端应用程序的 下载, 简化、 加快了 POS终端升级维护, 且保证升级后运行的更加可靠。
