| 摘 要： | 随着Web服务和网络技术的发展,越来越多的Web服务得以开发并发布到网络上。由于网络上存在的Web服务相互之间没有内在的必然联系,用户很难快速有效地获取和利用这些服务。本文设计了一种Web服务抓取解析器框架,包括URL抓取器、WSDL文档解析器和用于结构化存储Web服务信息的数据库等。该抓取解析器采用网络爬虫程序对互联网中的URL进行搜索,通过搜索发现分布在网络上的Web服务,并最终建立起一个关于Web服务的信息库,为共享Web服务提供条件。

| Abstract: | With the development of web service and network technology, more and more web service are developed and published to the Web. As there is no intrinsic and inevitahle relation among the web services on the web, it is difficult for the users to access and use those services quickly and efficiently. In this paper, a web service snatch and parse engine frame is designed, including URL snatcher, WSDL document parser and database for storing web service informalion structurally. The engine adopts a web crawler program to search URLs on the web. With this engine, the web services scattered on the web would be found, a service information database about web services would be built and it would provide conditions for sharing web services. |
