This project is a four-in-one instant messaging software. Its main functions are Group chats, private chats, and circles of friends. It can send text, voice, video, pictures, emoticons, red envelopes, transfers, etc. Messages can be withdrawn. Groups can be set to administrator, mute, and kick out. You can set whether you can view user information,@users, group announcements, etc., and support scanning codes to join groups. Messages are placed at the top, messages are not disturbed, you can directly invite friends to join groups, etc., there is a proxy function, support keyword blocking, vip function, check-in function, and support offline message push (ios does not need to be put on the shelves, but signatures need to support push through APN Push, Android needs to go to the app store, otherwise offline push cannot be realized. When placing an order, you must understand the offline message related process)
Historical chat records, pictures, and front-end programs on the APP side are cached locally, and the page opens in seconds. Support cloud synchronization of chat records, and you can also switch disconnected status pages. The fluency is comparable to that of a genuine copy.
You can start and run this project directly after completing the testing, and you can start it on the ios appstore for actual testing.
All errors discovered so far have been fixed, but there is no guarantee that no errors will be discovered in the future.
technical route
Back-end development language: PHP (native architecture)
Front-end development language: uniapp (hybrid development, non-pure native)
Socket push: GateWayWorker (supports distributed deployment, high concurrency, stress resistance, and does not use third-party paid push services)
Database: mysql
Development tools: hbuiderX, phpstorm
Currently, android, ios, pc web, and h5 are supported, and ios signatures, soft applications, and shelf services are not provided.
Server configuration:
Server operating system: LinuxCentos 7.x (unbutun is not supported)
Software environment: php5.6 Apache2.4 (or nginx) MySQL 5.6 (recommended pagoda)
Third-party plug-in: FFmpeg
In addition to the above configuration, no third-party payment APIs are used and no high operating costs are required
Performance reference:
The number of people online at the same time is limited by server memory. Generally, a server with 24G memory can support about 120W of concurrent connections.
User activity is limited by the processing power of the server's CPU. A 24-core server can achieve throughput of 45W per second.
