I want to validate the url end point using regex. Example end point like: /user/update.

First I tried with (/[A-Za-z0-9_.:-~/]*) but also matches http://url.com/user/update with javascript regex. I want the string to only validate pass if it is equal to /user/update like end points

CodePudding user response：

You can use regex look behind technique to get the path after the .com with /(?<=.com).*/

const matchEndPoint = (str) => str.match(/(?<=.com).*/)

const [result] = matchEndPoint('http://url.com/user/update');

console.log(result)

You might use a pattern like

^\/[\w.:~-] \/[\w.:~-] $

Or for example not allowing consecutive dashes like -- and match one or more forward slashes:

^\/\w (?:[.:~-]\w )*(?:\/\w (?:[.:~-]\w )*)*$

Explanation

• ^ Start of string
• \/\w Match / and 1 word chars
• (?:[.:~-]\w )* Optionally repeat a char of the character class and 1 word chars
• (?: Non capture group
  • \/\w Match / and 1 word chars
  • (?:[.:~-]\w )* Optionally repeat a char of the character class and 1 word chars
• )* Close group and optionally repeat
• $ End of string
