iOS 17 – URL encoding and not working with server API

by

I’ve an app that should call this API:

http://109.168.113.11/Acucgi/G7TestWeb.sh?funzione=charge_pms&utente=WXWX&password=TESTWWW1&azienda=RISTORANTE&modo=Json&fl_ad=A&camera=5&data_del=20231004&codadd[0]=V10&qtaadd[0]=1&impadd[0]=7,80&desadd[0]=Cappuccinos

In my app I’ve developed a class who can call this API, but from iOS 17 I’ve several problem because Apple has updated to RFC 3986 the url encoding.
Here’s my code:

let urlString = "http://109.168.113.11/Acucgi/G7TestWeb.sh?funzione=charge_pms&utente=WXWX&password=TESTWWW1&azienda=RISTORANTE&modo=Json&fl_ad=A&camera=5&data_del=20231004&codadd[0]=V10&qtaadd[0]=1&impadd[0]=7,80&desadd[0]=Cappuccinos"
guard let url = URL(string: urlString) else {
    print("!! url !!")
    return
}
var request = URLRequest(url: sysDatUrl)
request.httpMethod = "GET"
let task = URLSession.shared.dataTask(with: request) { (data, response, error) in
      [MANAGE RESPONSE]
}

By using this code the server answer me an error because my app use the following url:

http://109.168.113.11/Acucgi/G7TestWeb.sh?funzione=charge_pms&utente=WXWX&password=TESTWWW1&azienda=RISTORANTE&modo=Json&fl_ad=A&camera=5&data_del=20231004&codadd%5B0%5D=V10&qtaadd%5B0%5D=1&impadd%5B0%5D=7,80&desadd%5B0%5D=Cappuccinos

As you can see in my url iOS changed the character [ with %5B and ] with %5D. To work with my server I must use the [ and ], if I use the %5B and %5D my integration will not work anymore. There’s a way to keep the character [ and ]?
Thank you

    The issue is server side – characters like [ and ] are not allowed URL characters, so the ate percent-encoded. Your server should expect to receive those characters percent encoded. If anything, it’s weird that prior to iOS 17 the URL initializer returned valid URL instance when passed a string without those characters percent encoded

  • If this is really your server don’t misuse the URL query to pass hard-coded index subscription syntax. A better syntax could be to pass the index separately …data_del=20231004&codadd=V10&qtaadd=1&impadd=7,80&desadd=Cappuccinos&addIndex=0
