# barrage-fly 让弹幕飞 一个弹幕转发平台 [在线文档](https://barragefly.ordinaryroad.tech/) ## 1 项目简介 ### 1.1 功能 1. 监听不同平台直播间的弹幕 2. 使用统一的协议将弹幕转发出去 3. 内置简易实时弹幕显示 | | | | | ---------------------------------------------------- | ------------------------------------------------ | ------------------------------------------------ | | | | | ### 1.2 作用 屏蔽不同平台直播平台弹幕协议的差异,便于开发其他与弹幕相关的应用:实时弹幕大屏、弹幕互动、弹幕存档、弹幕分析、弹幕词云图等 ### 1.3 相关技术栈 - [Netty](https://netty.io) - [Spring WebFlux](https://docs.spring.io/spring-framework/reference/web/webflux.html) - [RSocket](https://rsocket.io) - [QLExpress](https://github.com/alibaba/QLExpress) ## 2 项目部署 项目前后端分离,可以使用Docker Compose进行部署,或者分别打包后部署 ### 2.1 Docker Compose > Docker Compose示例位于 `.docker`目录中 - arm64系统时,后端镜像请使用 `ordinaryroad-barrage-fly-arm64` - 使用mysql、nginx时需要先build - `docker compose build ordinaryroad-barrage-fly-mysql` - `docker compose build ordinaryroad-barrage-fly-nginx` - 在线生成RSA密钥对:https://www.bejson.com/enc/rsa/ (不需要-----BEGIN PUBLIC KEY-----) > 镜像加速与拉取 > > ```shell > # DOCKER_OPTS="--registry-mirror=https://mirror.ccs.tencentyun.com" > docker pull ordinaryroad-docker.pkg.coding.net/ordinaryroad-barrage-fly/docker-pub/ordinaryroad-barrage-fly:$APP_VERSION > docker pull ordinaryroad-docker.pkg.coding.net/ordinaryroad-barrage-fly/docker-pub/ordinaryroad-barrage-fly-arm64:$APP_VERSION > docker pull ordinaryroad-docker.pkg.coding.net/ordinaryroad-barrage-fly/docker-pub/ordinaryroad-barrage-fly-ui:$APP_VERSION > ``` #### 2.1.1 前端+后端 ```yaml # 需要的环境变量,其他可以环境变量可看每个目录下的.env文件,初始化sql位于`.docker/ordinaryroad-barrage-fly-mysql/sql/or_barrage_fly.sql` # MYSQL_HOST(注意请勿用localhost、127.0.0.1) # MYSQL_PORT # MYSQL_DATABASE # MYSQL_USERNAME # MYSQL_PASSWORD # SUB_BASE_URL(根据后端部署情况设置Client要连接的地址) # RSA_PUBLIC_KEY(RSA) # ADMIN_USERNAME(任务管理后台登录用户名) # ADMIN_PASSWORD(任务管理后台登录密码) # RSA_PRIVATE_KEY(RSA) version: "3.0" services: ordinaryroad-barrage-fly-ui: image: ordinaryroad-barrage-fly-ui container_name: ordinaryroad-barrage-fly-ui build: context: ./ordinaryroad-barrage-fly-ui volumes: -

Client请求Channel,并发送要订阅/取消订阅的任务ID(直播间弹幕转发任务) 3. 监听Server通过Channel回复的消息(转发过来的直播间弹幕) > 浏览器环境用WebSocket,其他环境可以用TCP 在 `connector-examples` 目录下提供了一些不同语言的例子可供参考 - python - [x] websocket - vue参考 `barrage-fly-ui/components/or/barrage/fly/task/RealTimeBarrage.vue` ## 4 如何配置消息的过滤与转换 > QLExpress相关说明 - 支持的方法 - 各种静态方法一般都可以用(需要先import) - [Hutool](https://www.hutool.cn/docs) - 向上下文添加变量 contextPut(key, value) - 添加后可直接通过key访问 - 发送弹幕 sendDanmu(taskId, danmu) - 别名:发送弹幕(taskId, danmu) - 任务必须正在运行中,弹幕内容String - 获取任务详情 getTask(taskId) > 消息封装类 `BarrageFlyMsgDTO`简介 | 变量名称 | 含义 | 类型 | 备注 | | -------- | -------------------------------------------- | ------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | platform | 消息所属平台 | String | BILIBILI/DOUYU | | roomId | 消息所属直播间房间号 | String | | | type | 框架定义的消息类型,提供了一些通用的属性 | String | [DANMU](https://github.com/OrdinaryRoad-Project/ordinaryroad-live-chat-client/blob/main/live-chat-client-commons/live-chat-client-commons-base/src/main/java/tech/ordinaryroad/live/chat/client/commons/base/msg/IDanmuMsg.java)/[GIFT](https://github.com/OrdinaryRoad-Project/ordinaryroad-live-chat-client/blob/main/live-chat-client-commons/live-chat-client-commons-base/src/main/java/tech/ordinaryroad/live/chat/client/commons/base/msg/IGiftMsg.java) | | msg | 收到的原始消息,不同平台不同消息类型字段不同 | IMsg | [ordinaryroad-live-chat-client](https://github.com/OrdinaryRoad-Project/ordinaryroad-live-chat-client) | ### 4.1 前置操作 #### 4.1.1 方法参数 msg: `BarrageFlyMsgDTO`,框架对消息的简单封装 #### 4.1.2 方法返回值 `Object?`,为空默认返回入参 `msg` ### 4.2 过滤 #### 4.2.1 方法参数 msg: `Object`,前置操作的返回值 #### 4.2.2 方法返回值 `Boolean`,`false`表示丢弃此消息;`true`表示需要该消息,并继续进行后置处理 ### 4.3 后置操作 #### 4.3.1 方法参数 msg: `Object`,前置处理的返回值 #### 4.3.2 方法返回值 `Object?`,Client最终将会收到的消息,为空默认返回入参 `msg` ### 4.4 一些例子 #### 4.4.1 只接收框架定义的消息 ``` return msg.type != null ``` #### 4.4.2 封装msg,增加随机数 ``` import cn.hutool.core.util.RandomUtil; map = new HashMap(2); map.put("originalMsg",msg); map.put("randomNumber",RandomUtil.randomNumbers(6)); return map; ``` #### 4.4.3 通过Http请求获取某个任务的信息,并扩充到msg中 ``` import cn.hutool.http.HttpUtil; import cn.hutool.core.bean.BeanUtil; task = HttpUtil.createGet("http://localhost:8080/task?id=1701211747748265984").execute().body(); map = BeanUtil.beanToMap(msg, false, false); map.put("task",task); return map; ``` #### 4.4.4 收到消息后发送弹幕 ``` import cn.hutool.core.util.RandomUtil; /**随机发送弹幕**/ if RandomUtil.randomInt(0,10) > 6 then 发送弹幕("u2","666666"+RandomUtil.randomNumbers(1)); return msg ``` #### 4.4.5 获取任务详情 ``` import cn.hutool.core.bean.BeanUtil; map = BeanUtil.beanToMap(msg, false, false); map.put("task",getTask("taskId")); return map; ``` ## 其他 - [ordinaryroad-live-chat-client](https://github.com/OrdinaryRoad-Project/ordinaryroad-live-chat-client) ## 免责声明 免责声明:仅供学术研究使用。对于违反相关法律、造成危害的滥用行为,开发者不负任何责任。
