URL validator converting all to lower case

[danielwmartin]

Hi,

When using the url validator it converts the string to lower case.

Is there anyway to stop this from happening? Not sure if this is a bug or by design but it causes me some issues as I need the case to be preserved for the bit 'THIS_IS_UPPER' in the following example.

value ='https://www.myDOMAIN.co.uk/THIS_IS_IN_UPPER'
url = validators.url(value, allow_empty = False)
print(f'validated url: {url}')

validated url:https://www.mydomain.co.uk/this_is_in_upper

Many thanks

Hi @danielwmartin !

I'm afraid that in v.1.3.4, validators.url() will always return a lowercase URL. While this is currently by design, it's actually a design error, since per the related RFC specs (which I just checked) portions of URLs may be case sensitive (specifically the path portion - domains are case insensitive). The bug will be fixed in v.1.3.5.

In the meantime, an alternative is to use the corresponding checkers.is_url() function. It will not return a URL, but it will give you True if your (case-sensitive) value is a valid URL:

from validator_collection import validators, checkers

value = 'https://www.myDOMAIN.co.uk/THIS_IS_IN_UPPER'
lowercase_value = validators.url(value)
is_valid = checkers.is_url(value)

print(lowercase_value)
# Prints 'https://www.mydomain.co.uk/this_is_in_upper'

print(is_valid)
# Prints 'True'
