Design And Implementation Of Micro Shop Service System Based On Yii Framework

In this era of prosperity of science and technology, the rapid development of mobile internet has become one of the most remarkable phenomenon in the field of global communications, and smart phones is growing worldwide popularity at an unprecedented rate. The prosperity of mobile internet and smart phones brought endless variety of mobile applications, and mobile APP not only has brought great convenience to people's daily lives, but also affect people's travel habit. After more than ten years of development, China's online travel market is beginning to show a trend of users from traditional PC shifting to the mobile terminal. Mobile APP provides users with a good service window and brings the enterprise huge data traffic, but there is difficulty lifting installed capacity and inefficient use and other issues. Recently Wechat public platform came into being as a typical "light app", and vast users of WeChat equals huge marketing value, also as an instant messaging tool WeChat has high user stickiness.This thesis combines online travel and micro-shop business model, then presents the design and implementation of a micro shop service system based on the WeChat common platform. The system is divided into three different subsystems according to user group division, they are backstage management system, seller system and store system, and the database is reasonable analysed and designed. The system adopts Yii, one of the most efficient PHP web application frameworks, besides its high performance due to its widely used internal lazy loading technology. This thesis introduces the implementation of the system using Yii framework, and gives the class diagram of the core module and core code. Combined with the actual project, the article makes appropriate tailoring and performance tuning to Yii framework. Also the MVC design pattern has been improved by adding a brand new layer called service, which can improve the system code reusability. In order to achieve a more rapid response to user, this system designs a multi cache mechanism, including CDN cache, memcache cache and local cache. Besides, this system introduces log management mechanism and web security protection measures. The system has been on-line, it runs well and reaches the design purposes.
