-------------------------------------------------------------------------------- 1 | # QTChatroom 2 | 3 | ## 简介 4 | 本项目是一个用QT实现的桌面端自部署聊天室系统软件，含服务端和客户端，使用经过SSL加密的TCP通信和SQLite数据库管理系统。 5 | 6 | 软件作者：[@omigeft](https://github.com/omigeft) （后端开发），[@Futurow](https://github.com/Futurow) （UI设计），[@123duduke](https://github.com/123duduke) （数据库设计） 7 | 8 | #### 运行方法 9 | 10 | 使用QT编译即可运行。作者测试时使用Qt5.12.9的MinGW64bit编译。 11 | 12 | 请注意一些约束比如用户名字符数1-20，密码字符数6-20且必须包含数字和字母。 13 | 14 | 服务器启动需要有SSL证书和密钥，作者编写了一个[Python脚本](server/src/generatecertandkey.py)用于生成自签名证书和密钥，如果服务器启动时找不到证书和密钥，会自动调用该脚本生成证书和密钥，需要本地配置了Python开发环境并安装了相应的库。此外，客户端会忽略自签名证书SSL错误来接受自签名证书。自签名证书与密钥仅用于测试和学习，请勿在生产环境中使用。对于生产环境，推荐使用由受信任证书颁发机构（CA）签发的证书。 15 | 16 | #### 已实现的主要功能有 17 | 1. 建立服务器 18 | 2. 局域网通信 19 | 3. 用户、聊天室管理，包括用户聊天室的创建和消息撤回等 20 | 4. 客户端可以进行注册、登录、创建和加入聊天室以及文本聊天等操作 21 | 5. 生成自签名SSL证书和密钥来加密TCP通信过程 22 | 23 | #### 计划表 24 | 1. 公网通信 25 | 2. 图片、文件传输等多媒体通信 26 | 3. 支持多国语言 27 | 4. 多线程的使用 28 | 5. 自定义样式皮肤、聊天室头像等 29 | 6. 将错误提示从终端显示改为弹窗/悬浮窗提示 30 | 7. 本地缓存聊天记录 31 | 32 | #### 软件UI各界面介绍 33 | 34 | ![UIIntroduction](assets/UIIntroduction.png) 35 | 36
