<div align=center><h2><font color="#d0e9ff">轻雪</font><font color="#a2d8f4">6.2</font></h2></div>
<div align=center><h4>轻量,高效,易于扩展</h4></div>
- 基于[Nonebot2](https://github.com/nonebot/nonebot2),有良好的生态支持
- 开箱即用,无需复杂配置
- 新的点击交互模式,拒绝手打指令
- 全新可视化`npm`包管理,支持一键安装插件
- 支持一切Onebot标准通信
## 1.安装和部署
1. 安装`Git`和`Python3.10+`
2. 克隆项目`git clone https://github.com/snowykami/LiteyukiBot`
3. 切换目录`cd LiteyukiBot`
4. 安装依赖`pip install -r requirements.txt`(如果多个Python环境请指定后安装`pythonx -m pip install -r requirements.txt`)
5. 启动`python main.py`
## 2. 配置
### 轻雪配置项(Nonebot插件配置项也可以写在此与dotenv格式不同应为小写)
如果不确定字段的含义,请不要修改(部分在自动生成配置文件中未列出,需手动添加)
```yaml
# 生成文件的配置项
command_start: [ "/", " " ] # 指令前缀
host: 127.0.0.1 # 监听地址
port: 20216 # 绑定端口
nickname: [ "liteyuki" ] # 机器人昵称
superusers: [ "1919810" ] # 超级用户
# 未列出的配置项(如要自定义请手动修改)
onebot_access_token: "" # Onebot访问令牌[具体请看](https://onebot.adapters.nonebot.dev/docs/guide/configuration)
default_language: "zh-CN" # 默认语言
log_level: "INFO" # 日志等级
log_icon: true # 是否显示日志等级图标(某些控制台不可用)
auto_report: true # 是否自动上报问题给轻雪服务器,仅包含硬件信息和运行软件版本
# 其他Nonebot插件的配置项
custom_config_1: "custom_value1"
...
```
### Onebot实现端配置
不同的实现端给出的字段可能不同,但是基本上都是一样的,这里给出一个参考值
| 字段 | 参考值 | 说明 |
|-------------|--------------------------|----------------------------------|
| 协议 | 反向WebSocket | 推荐使用反向ws协议进行通信即轻雪作为服务端 |
| 地址 | ws://`addrss`/onebot/v11 | 地址取决于配置文件,本机默认为`127.0.0.1:20216` |
| AccessToken | `""` | 如果你给轻雪配置了`AccessToken`,请在此填写相同的值 |
## 3.其他
### 常见问题
- 设备上Python环境太乱了pip和python不对应怎么办
- 请使用`/path/to/python -m pip install -r requirements.txt`来安装依赖,
然后用`/path/to/python main.py`来启动Bot
其中`/path/to/python`是你要用来运行Bot可执行文件
- 为什么我启动后机器人没有反应?
- 请检查配置文件的`command_start`或`superusers`,确认你有权限使用命令并按照正确的命令发送
- 怎么登录QQ等聊天平台
- 你有这个问题说明你不是很了解这个项目,本项目不负责实现登录功能,只负责处理消息
你需要使用Onebot标准的实现端来连接到轻雪并将消息上报给轻雪下面已经列出一些推荐的实现端
#### 推荐方案(QQ)
1. [Lagrange.OneBot](https://github.com/KonataDev/Lagrange.Core)目前点按交互目前仅支持Lagrange
2. [LiteLoaderQQNT OneBot](https://github.com/LLOneBot/LLOneBot)基于NTQQ的Onebot实现
3. 云崽的`icqq-plugin`和`ws-plugin`进行通信
4. `Go-cqhttp`(目前已经半死不活了)
5. 人工实现的`Onebot`协议自己整一个WebSocket客户端看着QQ的消息然后给轻雪传输数据
#### 推荐方案(Minecraft)
1. 我们有专门为Minecraft开发的服务器Bot支持OnebotV11/12标准详细请看[MinecraftOneBot](https://github.com/snowykami/MinecraftOnebot)
使用其他项目连接请先自行查阅文档若有困难请联系对应开发者而不是Liteyuki的开发者
## 4.用户协议
1. 本项目遵循`MIT`协议,你可以自由使用,修改,分发,但是请保留原作者信息
2. 你可以选择开启`auto_report`(默认开启)轻雪会收集运行环境的设备信息通过安全的方式传输到轻雪服务器用于统计运行时的设备信息帮助我们改进轻雪收集的数据包括但不限于CPU内存插件信息异常信息会话负载(不含隐私部分)
3. 本项目不会收集用户的任何隐私信息,但请注意甄别第三方插件的安全性
## 5.鸣谢
