BOT

创建BOT

import { Puppet } from "wechaty-puppet";

export function createBot(): Wechaty {
  const token: string = "YOUR_TOKEN....";
  const puppet = new Puppet({
    token,
  });

  return new Wechaty({
    name: "BotName",
    puppet,
  });
}

启动并登录BOT

import QRCode from "qrcode-terminal";

export async function prepareBot(): Promise<Wechaty> {
  const bot = createBot();

  // 在这里监听感兴趣的 bot 事件回调。
  bot.on("scan", (qrcode: string, status: ScanStatus) => {
    if (status === ScanStatus.Waiting && qrcode) {
      log.info(
        "TestBot",
        `onScan: ${ScanStatus[status]}(${status})\n\n ▼▼▼ Please scan following qr code to login ▼▼▼\n`
      );

      QRCode.generate(qrcode, { small: true });
    } else {
      log.info("TestBot", `onScan: ${ScanStatus[status]}(${status})`);
    }
  })
  .on("login", (user: Contact) => {
    // login 事件并不代表登录完全完成，只是通知目前登录的账号是什么，后续仍有初始化任务需要完成。
    log.info("TestBot", "%s login", user);
  })
  .on("logout", (user: Contact, reason: string) => {
    log.info("TestBot", "%s logout, reason:%s", user, reason);
  });

  await bot.start();
  await bot.ready();

  // ！！！只有当 bot ready 才能保证 bot 已经完全登录且初始化成功，这之后才能调用 bot 各种API

  return bot;
}

主动登出BOT

await bot.logout();
