我想捕獲檔案中的所有 URL，但不是來自 google、bscscan、github 等。
到目前為止，我有這個正則運算式作業
(www|http:|https:) [\W] (?!bscscan|google|binance|t\.me)[\w]
應用于本段時
https://bscscan.com testing123
website: https://www.yahoo.com
another one www.bing.com is great
www.binance.org
http://bob.bscscan.com
https://twitter.google.com
https://google.twitter.com
https://t.me/rawr omg
它只匹配
1) https://www
2) www.bing
3) http://bob
4) https:/twitter
但我希望它匹配
https://yahoo.com
www.bing.com
所需的修復
#1) 包括整個 URL 鏈接。
#2) 省略鏈接中任何提及否定前瞻詞的 URL。

試試這個，它有足夠的運算式允許你根據它的實作方式來修改它們：
/(|www\.|http\:\/\/|https\:\/\/)(?!(bscscan|google|binance|t\.me|twitter|bob))(yahoo\.com|bing\.com)/g
這將匹配以下任何變體：
https://yahoo.com. <- your required one
www.bing.com. <- your required one
www.yahoo.com
https://bing.com
http://bing.com
bing.com <- remove the "|" before "www" if you don't want this one
yahoo.com <- remove the "|" before "www" if you don't want this one
如果你添加(https\:\/\/www\.)|(http\:\/\/www\.)那么它也將匹配https://www并且http://www
