从Url Regex问题获取tictok id

Question

Regex不是我的强大套件，但我目前正在使用这个regex (\/[\d]+)从tictok获取id。

https://m.tiktok.com/h5/share/usr/6641141594707361797.html
https://m.tiktok.com/v/6749869095467945218.html
https://www.tiktok.com/embed/6567659045795758085
https://www.tiktok.com/share/user/6567659045795758085
https://www.tiktok.com/trending?shareId=6744531482393545985

我从所有链接中获得id，除了带有shareId=xxxxxxxxxxx的链接。我将原来的regex修改如下，但仍然没有从shareId=xxxxxxxxxxx链接中获得id。任何帮助都将不胜感激。

(?:|shareId=)(\/[\d]+)

Answer 1

使用您所显示的示例，请尝试以下regex。下面是显示正则表达式的在线演示。

\bhttps?:\/\/(?:m|www)\.tiktok\.com\/.*\b(?:(?:usr|v|embed|user)\/|\?shareId=)(\d+)\b

解释：在这里添加了对已使用正则表达式的详细说明。

\bhttps?:\/\/         ##Mentioning word boundary to avoid partial matches for http/https followed by : 2 slashes.
(?:m|www)             ##In a non-capturing group matching m OR www
\.tiktok\.com\/       ##Followed by .tiktok.com
.*\b                  ##Doing greedy match followed by word boundary.
(?:                   ##Starting one non-capturing group here.
  (?:                 ##Starting one more non-capturing group here.
    usr|v|embed|user  ##matching usr OR v OR embed OR user here.
  )                   ##Closing previously opened non-capturing group here.
  \/                  ##Followed by a literal / here.
  |                   ##putting OR condition here.
  \?shareId=          ##matching ?ShareId= here.
)                     ##Closing firstly opened non-capturing group here.
(\d+)                 ##Creating one and only capturing group which has digits in it.
\b                    ##Followed by word boundary here to avoid partial matches.

已经给出了一些可行的答案，但我想提出一个漂亮的解决方案：

([=/][\d]+)

第一组检查“=”或“/”符号。请参阅https://regex101.com/r/9uNJZ1/1

您还可以为问题中的tiktok urls设置特定的模式，并对数字使用捕获组：

https?://(?:m|www)\.tiktok\.com\b\S*?(?:/(?:use?r|v|embed)/|\bshareId=)(\d+)\b

解释

• https?://(?:m|www)\.tiktok\.com\b匹配urls的开头
• \S*?匹配可选的非空格字符，尽可能少
• (?:/(?:use?r|v|embed)/|\bshareId=)匹配/usr/ /user/ /v /embed/ shareId=中的一个
• (\d+)捕获组1，匹配1+数字
• \b阻止部分单词匹配的单词边界
