Telegram Bot API 4.5 Markdown V2上的转义字符给超级链接带来麻烦

问题描述

TelegramBot API 4.5附带了新的解析模式Markdown V2。同时，这些_ * [ ] ( ) ~ > # + - = | { } . !字符必须用前面的字符进行转义。

.replace(/[-.+?^$[](){}\]/g, '\$&')用作添加转义字符的解决方案，效果非常好，但遗憾的是，此解决方案会影响超级链接方法[inline URL](http://www.example.com/)，因为它取代了[inline URL](http://www.example.com/)

解决方案

bot.on('text', (ctx) => {
  const { chat } = ctx.message;
  const msgs = `Here is the [rules](https://telegra.ph/rules-05-06) Please read carefully and give the details which mentioned below.

  const msgmsgWithEscape = msgs.replace(/[-.+?^$[](){}\]/g, '\$&')

  ctx.telegram.sendMessage(
    chat.id,
    msgmsgWithEscape,
    {
      parse_mode: 'MarkdownV2',
    }
  )
});

结果

推荐答案

为了避免转义[...](http...)格式的链接，您可以匹配它们并捕获到一个组中，然后只匹配所有字符以在其他上下文中转义。然后，检查Group 1值，如果不为空，则替换为Group 1值，否则，替换为转义字符：

const msgmsgWithEscape = msgs.replace(/([[^][]*](http[^()]*))|[_*[]()~>#+=|{}.!-]/gi,

console.log(msgmsgWithEscape);
