Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

v2.2.0

Published

将聊天消息通过zeromq转发到指定网络位置

Readme

@maorongwan/koishi-plugin-message-bridge v2.0

npm(https://www.npmjs.com/package/@maorongwan/koishi-plugin-message-bridge)

通过 ZeroMQ 在 Koishi 与外部程序(如 C#)之间双向转发聊天消息。

v2.0 新特性

  • 🏗️ Per-bot 隔离:通过 bot-added / bot-removed 事件自动管理,每个 bot 独享独立端口(basePort + botIndex * 10
  • 📡 17 个 API 方法:覆盖消息发送、文件上传、群管理、查询等完整操作集
  • 🔄 统一 JSON 响应{ code, data/error } 格式,错误处理一致
  • 🧪 测试 REP:独立 socket 端口用于开发调试
  • 🔗 SendChain 防并发:per-bot Promise 链式发送,避免 ZeroMQ "Socket is busy writing"
  • 🔁 指数退避重试:最多 3 次,间隔 1s / 2s / 4s

功能

  • 📤 消息转发(PUSH):通过 middleware 将收到的消息序列化后 PUSH 到 ZeroMQ socket
  • 📥 指令下发(PULL):监听 PULL socket,接收外部指令并调用 Bot API 发送消息
  • 🔁 请求-应答(REP):监听 REP socket,处理查询/操作请求并返回结构化响应
  • 🧪 测试 REP:独立 REP socket,用于开发/调试时手动测试 API

配置项

| 字段 | 类型 | 默认值 | 说明 | |------|------|--------|------| | basePort | number | 5555 | 基端口,实际端口为 basePort + botIndex * 10(PUSH/PULL/REP 分别占用 3 个连续端口) | | testRepEnabled | boolean | true | 是否启用测试 REP socket | | testRepPort | number | 15559 | 测试 REP 端口 |

端口分配规则

Bot 索引从 0 开始,按 ctx.bots 顺序排列:

| Bot 索引 | PUSH 端口 | PULL 端口 | REP 端口 | |----------|-----------|-----------|----------| | 0 | basePort | basePort+1 | basePort+2 | | 1 | basePort+10 | basePort+11 | basePort+12 | | 2 | basePort+20 | basePort+21 | basePort+22 |

传输协议

Koishi → 外部(PUSH)

{
  "timestamp": 1700000000,
  "userId": "123456",
  "username": "user",
  "channel": { "id": "...", "type": 0 },
  "guildId": null,
  "platform": "onebot",
  "content": "消息内容",
  "messageId": "msg-123",
  "botId": "1740451858"
}

外部 → Koishi(PULL)

发送私聊消息:

{
  "type": "SendMessage",
  "botId": "1740451858",
  "channelId": "123456",
  "content": "你好",
  "isGroup": false
}

发送群消息(两种方式):

方式一 — SendMessage + isGroup:

{
  "type": "SendMessage",
  "botId": "1740451858",
  "channelId": "987654",
  "content": "群发消息",
  "isGroup": true
}

方式二 — SendGroupMessage(语义别名):

{
  "type": "SendGroupMessage",
  "botId": "1740451858",
  "groupId": "987654",
  "content": "群发消息"
}

    "isGroup": false
  }
}
// 响应

测试 REP

测试 REP socket 独立于 per-bot REP,提供一个直接调用 API 的入口。

  • 端口15559(默认,可通过 testRepPort 配置)
  • 安全约束:仅绑定 selfId=1740451858 的 bot(硬编码,不可配置)

请求格式

{
  "type": "TestMethod",
  "method": "GetFriendList",
  "botId": "1740451858",
  "params": {}
}
  • method 大小写不敏感(如 getfriendlist 自动映射到 GetFriendList
  • botId 必须匹配已上线的 bot

示例

# 使用 zeromq 客户端测试
node -e "
const zmq = require('zeromq');
(async () => {
  const req = new zmq.Request();
  req.connect('tcp://localhost:15559');
  await req.send(JSON.stringify({type:'TestMethod', method:'GetFriendList', botId:'1740451858', params:{}}));
  const [resp] = await req.receive();
  console.log(resp.toString());
})()
"
