Expression régulière pour trouver des URL dans une chaîne de caractères

Question

Quelqu'un connaît-il une expression régulière que je pourrais utiliser pour trouver des URL dans une chaîne de caractères ? J'ai trouvé beaucoup d'expressions régulières sur Google pour déterminer si une chaîne entière est une URL, mais j'ai besoin de pouvoir rechercher des URL dans une chaîne entière. Par exemple, j'aimerais pouvoir trouver www.google.com y http://yahoo.com dans la chaîne suivante :

Hello www.google.com World http://yahoo.com

Je ne recherche pas d'URL spécifiques dans la chaîne. Je recherche TOUTES les URL de la chaîne, c'est pourquoi j'ai besoin d'une expression régulière.

Answer 1

Cette expression rationnelle permet d'attraper des domaines tels que goo.gl ou domains.google .

Answer 2

^(http|https|ftp|ftps)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?

Cela permettra de vérifier l'url link....

Answer 3

J'utilise la logique qui consiste à trouver le texte entre deux points ou deux périodes.

la regex ci-dessous fonctionne bien avec python

(?<=\.)[^}]*(?=\.)

Answer 4

La recherche d'une URL dans un texte ne devrait pas être si complexe

(?:(?:(?:ftp|http)[s]*:\/\/|www\.)[^\.]+\.[^ \n]+)

Answer 5

J'ai utilisé cette

^(https?:\\/\\/([a-zA-z0-9]+)(\\.[a-zA-z0-9]+)(\\.[a-zA-z0-9\\/\\=\\-\\_\\?]+)?)$
