You can use the following regex to pull out the data you need: /^(https:\/\/steamcommunity\.com\/id\/)?([^\s\/]+)\/?$/(您可以使用以下正则表达式提取所需的数据：/ /^(https:\/\/steamcommunity\.com\/id\/)?([^\s\/]+)\/?$/ : /^(https:\/\/steamcommunity\.com\/id\/)?([^\s\/]+)\/?$/)

Basically, this regex allows for the URL to be there (or not), followed by any characters that are not whitespace and not "/".(基本上，此正则表达式允许URL存在（或不存在），后跟不是空格也不是“ /”的任何字符。) Then at the end, it allows for a trailing "/".(然后最后，它允许在末尾加上“ /”。) I don't know what characters steam allows in their custom URLs.(我不知道Steam允许在其自定义URL中使用哪些字符。) If you know, replace [^\s\/]+ with a regex that matches them.(如果您知道，请用与它们匹配的正则表达式替换[^\s\/]+ 。) This has the added benefit that it will reject values that do not match.(这具有额外的好处，它将拒绝不匹配的值。) const tests = [ 'https://steamcommunity.com/id/ethicalhackeryt/', 'https://steamcommunity.com/id/ethicalhackeryt', 'ethicalhackeryt', 'https://google.com/images' ] tests.forEach(test => { const id = test.match(/^(https:\/\/steamcommunity\.com\/id\/)?([^\s\/]+)\/?$/); if (id) { console.log(test, id[2]); } else { console.log(test, 'Not a steam id'); } });
