复杂语境下Web动态页面分层重构方法研究

摘要

针对复杂语境下Web语境敏感页面的页面冗余问题,论文分析了传统设计中页面设计及在动态控制方面的不足,基于COP提出一种动态的基于语境为中心的层槽页面(LSP,Layer-Slot Page)语法,给出LSP页面实现原理.通过自定义语境表现层标签实现动态页面中语境约束的细粒度描述,并驱动Drools规则引擎计算规则文件,激活LSP分层信息.最后通过实例验证该重构方案安全有效,具备语境变化的动态适应能力,支持细粒度的安全访问控制.%Considering complex context,for the problem of page redundancy in Web context-aware page,the traditional method of page design and the deficiency in dynamic control is analysed in this paper,and the COP as a reference to propose a dy-namic Layer-Slot page syntax which is centered on context is taken,while given the working principle. Through the definition of the presentation layer label correlated with context,the context constraint fine-grained access control in dynamic page is achieved, then it drives the Drools engine to compute rule files and activate the LSP layer information. Finally,the security and efficiency of the refactoring method is validated,which has the ability to adapt with the changeable context and provides the fine-grained securi-ty access control.
