摘要
提出一种基于服务请求语言的统一 Web 服务框架 UWSF。该框架通过统一的服务发布构件对外提供 Web服务,并以服务项为单位进行组织,客户端通过对服务项的灵活组合获得各种定制的服务。引入服务请求语言作为客户端服务请求以及交互策略的描述手段。服务请求在服务端解释执行,使得双方的交互过程能够在会话环境中进行,并且减少了由于中间结果传输造成的带宽占用。服务端执行基于状态图的流程级交互控制以及基于权限检查接口的服务项级权限控制,保证了会话过程的合法性与完整性。
This paper presents a unified Web Services framework based on service request language. In this framework, Web Services are provided through a unified Web publishing component and organized by service items. The client can obtain various eustomised services by flexible combination of those service items. The service request language is introduced to serve as the description method for the service request and interoperation policy of the client. The service request is interpreted and executed on the server, this can provide conversation support for the interoperation and greatly decreases the occupation of bandwidth. Conversation control based on state diagrams and authority check of service items are performed on the server. Thus the validity and integrality of the conversation can be ensured.
