在 Google Cloud VM 实例中获取 Telegram API 失败

Question

所以，我想使用 Ubuntu 最新版本或最高版本在 Google Cloud VM 实例中发送 Telegram API Bot。我正在使用 NodeJS 程序并 fetch 来运行 API。

但是我收到了这个错误：

TypeError: fetch failed
    at node:internal/deps/undici/undici:13185:13
    at process.processTicksAndRejections (node:internal/process/task_queues:105:5)
    at async exports.sendMessage (/root/anonymous/controller/telegram/sendMessageController.js:19:21) {
  [cause]: AggregateError [ETIMEDOUT]: 
      at internalConnectMultiple (node:net:1117:18)
      at internalConnectMultiple (node:net:1185:5)
      at Timeout.internalConnectMultipleTimeout (node:net:1711:5)
      at listOnTimeout (node:internal/timers:596:11)
      at process.processTimers (node:internal/timers:529:7) {
    code: 'ETIMEDOUT',
    [errors]: [ [Error], [Error] ]
  }
}

这是我的代码（sendMessageController.js）：

const dotenv = require("dotenv");

dotenv.config();

exports.sendMessage = async (req, res) => {
  const { message } = req.body;

  if (!req.body || Object.keys(req.body).length === 0) {
    return res.status(400).json({
      status: 400,
      message: "Bad request",
    });
  }

  try {
    const token = process.env.TELEGRAM_TOKEN;
    const url = process.env.TELEGRAM_API_URL;
    const channel = process.env.TELEGRAM_CHANNEL_ID;
    const request = await fetch(`${url}/bot${token}/sendMessage`, {
      method: "POST",
      headers: {
        "Content-Type": "application/json",
      },
      body: JSON.stringify({
        chat_id: channel,
        text: message.replace(/[_*[\]()~`>#+-=|{}.!-]/g, "\\$&"),
        parse_mode: "MarkdownV2",
      }),
    });

    const response = await request.json();

    console.log(response);
    res.status(200).json({ status: 200, message: "Success", data: response });
  } catch (error) {
    console.error(error);
    res.status(500).json({ status: 500, message: "Internal server error" });
  }
};

我使用 REST API 触发，问题出自此代码。

我期望的是提取工作正常，没有像本地主机那样失败。

好吧，显然我必须在正文之后添加

const request = await fetch(`${url}/bot${token}/sendMessage`, {
   method: "POST",
   headers: {
     "Content-Type": "application/json",
   },
   body: JSON.stringify({
     chat_id: channel,
     text: message.replace(/[_*[\]()~`>#+-=|{}.!-]/g, "\\$&"),
     parse_mode: "MarkdownV2",
   },
   {
     family: 4,
   }
  ),
 }
);

代码可以运行，但是安全吗？
