[玩具]我把issue打印出来然后揉掉....

起因是以前在做 issues-helper 推广的时候一直没仔细钻研过具体原理，就想着把这个链路跑通顺便自己做一个玩具。

玩具目标是：指定项目的有新的 issue 时打印出一张标签来提醒我有新的任务了。

流程

项目 -> 注册本地 runner

创建issue -> 触发 github action -> 本地 runner 触发 -> 打印一张贴纸

实践

（一）注册 runner

1. 项目点击 Action 注册一个 Self hosted runners

1. 按照流程在本地注册 runner

1. 检查是否在线

（二）触发 issue 指定动作

1. 设计，我想在 issue 创建的时候进行提醒，并且在分配给某位同事的时候打印出一张贴纸，然后把任务贴在同事电脑上
2. 编写 action 在issues 有指定动作时触发，由于本地已经有 node 环境了，脚本不用编写安装 Node环境

name: CI

on:
  issues:
    types: [opened, edited, closed, reopened, assigned, unassigned]

jobs:
  issue-create:
    runs-on: self-hosted
    steps:
      - name: Check Out
        uses: actions/checkout@v2

      - name: Issue Create
        uses: ./
        with:
          action: ${{ github.event.action }}
          issue: ${{ toJson(github.event.issue) }}
          repo: ${{ toJson(github.event.repository) }}

1. 在根路径(uses: ./)下创建 action.yml 作为运行配置

name: 'Issue to Print'
description: 'test action'
author: 'ajuner'

runs:
  using: 'node16'
  main: 'index.js'

inputs:
  action:
    description: 'Action name'
  issue:
    description: 'Issue number'
  repo:
    description: 'Repository name'

1. 在 index.js 中接收 action 参数

const action = core.getInput("action");
const issue = JSON.parse(core.getInput("issue"));

console.log("action", action);
console.log("issue", issue);

（三）编写打印相关代码

使用条码热敏打印机 TSPL 指令

const core = require("@actions/core");
const iconv = require("iconv-lite");
const escpos = require("node-escpos-win");
const usb = escpos.GetDeviceList("USB");
const list = usb.list.filter(
  (item) => item.service === "usbprint" || item.name === "USB 打印支持"
);
const printer = list[0];

if (!printer) {
  console.warn("没有连接usb打印机");
  return;
}

const action = core.getInput("action");
const issue = JSON.parse(core.getInput("issue"));

console.log("action", action);
console.log("issue", issue);

const cmds = [
  "SIZE 45 mm,60 mm",
  "GAP 2 mm,0 mm",
  "DENSITY 15",
  "SPEED 4",
  "DIRECTION 1",
  "CLS",
];

const actionText = {
  opened: `有新的issue #${issue.number}`,
  closed: `issue #${issue.number} 已关闭`,
  reopened: `issue #${issue.number} 已重新打开`,
  edited: `issue #${issue.number} 有更新`,
  assigned: `issue #${issue.number} 已分配`,
  unassigned: `issue #${issue.number} 已取消分配`,
};

cmds.push(`TEXT 0,20,"TSS24.BF2",0,1,1,"${actionText[action]}"`);
cmds.push(`TEXT 0,60,"TSS24.BF2",0,1,1,"标题：${issue.title}"`);
cmds.push(`TEXT 0,100,"TSS24.BF2",0,1,1,"用户：${issue.user.login}"`);
if (!!issue?.assignees?.length) {
  const logins = issue.assignees.map((item) => item.login).join("、");
  cmds.push(`TEXT 0,180,"TSS24.BF2",0,1,1,"任务分配者：${logins}"`);
}
cmds.push("PRINT 1", "");

const content = iconv.encode(cmds.join("\r\n"), "gbk");

const res = escpos.Print(printer.path, content);

console.log(res);

（四）测试issue

查看打印效果

（五）揉掉这个需求然后丢到垃圾桶里
