用 W5500构成的低成本嵌入式 Web服务器

在HTML5的时代下，随着Web服务器的数量与日俱增，B／S（Browser／Server）模型得到了更加广泛的应用。在嵌入式领域，客户端可以实现远程监控服务器的功能，这不仅需要服务器解析用户请求，而且需要对用户指令作出快速准确的响应。本文在OSI互联参考模型的基础上，深入研究HTTP通信机制，抛弃了现有复杂的Web服务器框架，自主搭建了一个在单片机上运行的Web服务器，它能即时响应HTML网页、JavaScript脚本和CSS样式的请求，且具有占用资源少、运行效率高、安全性好、低功耗、低成本的特点。

Low-cost Embedded Web Server Based on W5500

In the era of HTML5 ,the B/S(Browser/Server) model has been applied in many applications with the number of Web server increasing .In the embedded field ,if the client wants to realize the function of the remote monitoring server ,the Web server not only need to parse the user requests ,but also need to make a quick and accurate response to the commands .Based on the OSI reference model and the HTTP communication ,a Web server is established ,which can run in a microcontroller ,without any complex web server framework . It can give a real‐time response to the traditional requests like HTML ,JavaScript and CSS ,and has the characteristics such as low re‐source consumption ,high efficiency ,good security ,low power consumption and low cost .
