应用Web服务实现远程教育平台间数据传输

Implementing Data Transfer between Remote Education Platforms Based on Web Service

本文结合实际应用，主要研究远程教育平台应用Web服务技术实现跨Internet进行数据交换的问题。在具体的设计中，采用Axis框架所提供的机制来实现数据交换的功能，但是同时也产生了一些问题。针对数据交换期间所产生的大数据量传输超时和低效等问题，本文提出了基于SOAP消息处理的处理方案（包括压缩机制和MIME Multipart机制）和基于轻量级二进制Web服务协议Hessian的数据传输方案，并进行了一些有益的尝试，得出了一些有价值的结论。

This paper places emphasis on the research that is to implement data transfer via the Intemet between remote education platforms based on the web service, which is supported by the current project. In the actual design, when utilizing the Axis framework to implement the functions of data exchange, the problems, however, come into being at the same time. Aiming at the problems generating when transferring the amount of data in long latency, this paper provides two solutions for practice. One is based on SOAP message that adopts compression mechanism and MIME Multipart mechanism, the other is based on the lightweight binary web service protocol-Hessian to make web services usable.
