电报Bot 4.5 MarkdownV2上的转义字符给超链接带来了麻烦

Question

电报Bot 4.5提供了新的解析模式，MarkdownV2。同时，这些_ * [ ] ( ) ~ > # + - = | { } . !字符必须使用前面的字符\进行转义。

.replace(/[-.+?^$[\](){}\\]/g, '\\$&')用作添加转义字符的解决方案，效果很好，但不幸的是，该解决方案确实影响了超链接方法[inline URL](http://www.example.com/)，因为它取代了\[inline URL\]\(http://www.example\.com/\)。

溶液

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',
    }
  )
});

Answer 1

为了避免转义像[...](http...)格式的链接，您可以匹配它们并捕获到一个组中，只需匹配所有字符以便在其他上下文中转义。然后，检查Group 1值，如果它不是空的，用Group 1值替换，否则，用转义字符替换：

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

console.log(msgmsgWithEscape);
