问题 填空题

利用中间件Middleware的高层 【11】 可以将底层网络协议与实现技术隔离开来,使得程序员可以将精力集中在应用软件编程上。

答案

参考答案:应用程序编程接口

解析: 在Client/Server架构中,如果程序有很多地方是依赖于网络协议与网络软件的话,那么这种程序就很难编写、维护,也很难移植。为了解决应用程序对网络过分依赖的问题,一种有效的编程方法就是在客户机与服务器之间增加一层软件,这就是所谓的“中间件”。利用中间件所提供的高层应用程序编程接口(API),就可以将底层网络协议与实现技术屏蔽起来,使得程序员可以将精力集中在应用软件编程上。实际上,中间件的主要作用就是将应用与网络隔离开来。
