Design And Implementation Of The Wifi Authentication Login System Based On Portal

With the rapid development of intelligent mobile terminals wireless Internet devices and the Internet,WiFi has become an indispensable way for people to access the Internet,and is forming a new intelligent business form.Compared with the traditional wifi,the new smart business WiFi is not only able free to provide user networks,but also to push advertising and services.Therefore,it is very important to build an intelligent WiFi network which can manage and service,and realize its traffic value.In order to establish a secure network environment,identity authentication is the premise of using network services.Under the background,this paper designs and implements a WiFi authentication login system which is located on the WLAN network of an operator.The main work of this paper is as follows:1.This paper introduced the development of the new media form wifi model and the significance of its research,and introduces the status of wifi technology and authentication technology in detail.2.The paper made a comparative analysis of three kinds of mainstream authentication technology.In view of the characteristics of portal authentication,combined with the requirements of the system,this paper finally selects the portal authentication mode.The message format and type of portal protocol and rdaius protocol are also introduced in detail.3.Starting from the system performance,this paper analyzes and compares the networking and forwarding mode of WiFi technology,and finally adopts the thin AP combination networking and local forwarding mode,and unifies configuration AC to build network environment according to the principle of networking.Software development uses a springMVC framework that can seamlessly integrate with spring,which makes the processing of AJAX requests more convenient.AJAX request way unified for the POST mode,the data returned to JSON format,which is easy to maintain the code.4.The system logic structure,software architecture and the main process of portal authentication login are designed by the requirement analysis of the system.User login authentication,login,offline and its background management module have been well implemented5.At the end of this paper,the functional test and performance test of the system are carried out.The test results show that the system meets the expected requirements.
