This project USES a variety of frameworks and tools to simplify the development cost and difficulty.The function modules of the app include user registration, user login, user search for friends, adding friends to each other, refusing to add friends, chatting with friends, modifying nickname, generation of user qr code, uploading of users' avatar and downloading.Netty, an open source Java framework that provides asynchronous, event-driven tools, USES eclipse software and frameworks such as spring boot to develop the back end. MUI is a front-end framework of relatively small magnitude, which can be downloaded and used according to the requirements of corresponding modules. This time, the front-end MUI project is developed with HBuilder software. The database USES MySQL to store the user's information. FastDFS is an open source distributed file system. In this design, we can upload and download the user...
