I am trying to write password validation function with regexp and don't know how to do it. Golang regex is different to other language. Have someone an idea, how this regexp pattern should looks like?
The pattern should validate:
/*
* Password rules:
* at least 7 letters
* at least 1 number
* at least 1 upper case
* at least 1 special character
*/
分享 The right regexp would be... no regexp here.
You can define a custom function that would validate the password, and combine it with other frameworks helping validating a field, like mccoyst/validate (mentioned in this discussion about parameter validation)
You also have go-validator/validator whic allows to define similar validations (but I would still use a custom validator instead of one or several regexps).
Note: go regexp is based on re2, an efficient, principled regular expression library).
So the major trade offs are no back-references for example:
(abc)\1and no matching look-behinds.
In exchange you get high speed regex.
