How to keep percent encoded spaces in an url?

Blaise70

Hi,

I'm facing an issue when I try to open a site using QDesktopServices::openUrl(). The url I have in QString contains a list of space separated values in the query part. I replaced them with the percent encoded value (%20) already, but when this string us passed to QUrl it automatically changes them back to spaces.
Why? How can I disable this unwanted behaviour?
I would expect if I pass a string with spaces it encodes them to percent encoded values and not this opposit.
Thanks and regards,
Laszlo

Hi,
I got an error message that the query is incorret. So my first understanding was that it requires encoded spaces. I finally realised that ther was a typo. So it works now with not encoded spaces. The missleading error message directed me into completley wrong direction.
Sorry for eating up your time and thank you all for helping me.
I really appreciate it.
Thanks and regards,

@Blaise70 Maybe you need to use QUrl::DecodedMode, see https://doc.qt.io/qt-6/qurl.html#ParsingMode-enum

I don't think you are supposed to care, space and %20 are the same character. But I see there is enum QUrl::ComponentFormattingOption

QUrl::EncodeSpaces 0x100000 Leave space characters in their encoded form ("%20").

Thanks for your kins answer. Yes, I tried and according to the help it should keep spaces in both form, but somehow it always converts %20 back to ' '.
Anyway, I'll keep trying.

Thanks for your kind answer.
Yes, I looked at it, but unfortunatelt all the functions accepting this type are returning QString. Like query which seems converting the query part of the url into a Qstring. setQuery seems OK except it uses the ParsingMode enum and even though TolarentMode should work according to the help, it seems not.
I'll keep trying,
Thanks and regards,

I don't understand the problem here - what exactly does your external program need? I don't see any need to percent encode the space for an argument of a programm so why do you need it?
