[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

项目点击 Action 注册一个 Self hosted runners

按照流程在本地注册 runner

检查是否在线

（二）触发 issue 指定动作

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
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

yaml 复制代码

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) }}

在根路径(uses: ./)下创建 action.yml 作为运行配置

vbnet 复制代码

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'

在 index.js 中接收 action 参数

ini 复制代码

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

ini 复制代码

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
