Design And Implementation Of Sharing Takeaway System Based On Wechat Platform

With the promotion of the Eleme,MeiTuan,Baidu and some other giant companies,eating takeaway has become an indispensable part within lives of office clerks,students,as well as families,teams,which in the meantime,is really convenient for residences.However,it brings a series of problems such as "leakage of user privacy","low-speed delivery","process inefficiency",etc.The user privacy could be leaked as the merchant prints customers' personal details on the receipts,which give a way for others stealing those information,and as a result of which,the security of customers' personal details is worrying.When delivering the food,the takeaway staffs often spend their time on waiting for the elevator and the user to go downstairs to take a meal,looking for the specific building and room,which creates inefficiencies and slow deliveries.Although some of the office space and the district has a number of collection areas and dining cabinets,wrong taken still exists.Base on that,electronic containers were introduced.To using that,staffs have to input order number and verification message.The operation is cumbersome and complicated,which however,results in inefficiency.In order to solve the given problems,this paper designed a shared takeaway machine system based on WeChat platform.The main work is as follows:(1)In the traditional mode,the merchant prints out the information list directly after receiving the user's order and attaches it to the takeaway.It exposes the customer privacy to the public and is easily stolen and exploited by criminals,causing the leakage of personal privacy.In order to solve this problem,this paper studies a protection mechanism for user privacy based on the RC4 symmetric encrypted in QR code.The information is displayed in the form of a chaotic RC4 symmetric encrypted two-dimensional code.In the public environment,only takeaway machine specified by server to decrypt and get user information and perform related operations,the protection mechanism greatly improves the security.(2)Designed and implemented a shared takeaway machine based on scanning,the delivery can scan the encrypted QR code directly attached on the order after arriving to the designated shared takeaway machine.The approach of "one cargo one counter" can avoid many troubles,like the wrong take and missed take,saving much time to wait for and look for the place,as well as the cumbersome that the traditional shelves need to enter the order number and verification information manually is solved.In this paper,it is quick and convenient for both the staffs and customers to access or put the takeaway out relying on scanning QR code only.(3)Designed and implemented a takeaway systematic management system based on mini program in WeChat.There are many advantages to this system.Firstly,users with WeChat account can directly enter the mini program to order and take meals without additional applications.Secondly,good security,since the https transmit information and data after encrypted,so the pickup code generated by server can be transmitted to the user's mobile phone directly without encryption.Last but not the least,low marketing cost,relying on WeChat platform's massive users,the business can reduce marketing costs dramatically.
