摘要
为了实现嵌入式Web服务器中的动态Web功能,讨论了适用于嵌入式环境的CGI与SSI技术,在分析其优缺点的基础上提出了CGI与SSI技术相结合的"扩展CGI"解决方案。该方法克服了CGI方式可维护性差的缺点,减少了服务器生成动态页面时的开销。在成功设计扩展CGI的基础上,给出了嵌入式Web服务器的具体实现方法。实验结果表明了设计的可行性和有效性。该方法具有结构清晰、合理利用嵌入式系统资源和易于开发与维护的特点。
In order to implement the function of dynamic web in an embedded web server, the CGI and SSI technology which are suitable for embedded environment is discussed. The advantages and disadvantages of the CGI and SSI technology are analyzed. An ＂Extended CGI＂ solution is proposed, which combines the CGI technology and SSI technology. The solution can improve the maintainability of the CGI program and save the server overhead when generating dynamic pages. Based on the successful design of the extended CGI, the implementation of the embedded web server is provided in detail The implementation of the system shows its feasibility and effectiveness. This solution possesses the characteristics such as clear structure, rational utilization of resource in embedded systems, easy development and maintenance.
