基于FTP协议的异步Web服务

An Asynchronous Web Service Architecture Based On FTP Protocol

在实际应用中 ,异步Web服务面临消息可靠性和服务安全性问题 .目前 ,这两个问题被视为独立的两方面 ,没有从整个系统应用的角度加以分析和处理 ,缺乏一套比较完整、便捷的解决方案 .通过对当前实现异步Web服务的几种方法进行介绍和分析 ,结合FTP自身优势 ,在同步通信的基础上 ,将SOAP消息转换成XML文件并以存储 /转发的形式调用服务 。

There two major problems when we use asynchronous Web services, the reliability of messaging and the security of the Web services. The two problems, however, are treated and analyzed independently and there are no perfect solutions form the point of view of a whole application system. After introducing and analyzing several implementations methods of asynchronous style, an innovated architecture is advanced by store and transfer mechanism, that is transforming SOAP messages into XML files, and transporting requests simply and reliably on FTP protocol.
