Don’t percent-encode the value you supply to URLQueryItem
. URLQueryItem
does that for you. As it is, you are double percent-encoding it (i.e., it is percent-encoding the %
of your percent-encoded string).
So, instead, simply supply the simple string, and let URLComponents
take care of it:
let queryItem = URLQueryItem(name: "scope", value: "channel:manage:polls+channel:read:polls")
As an aside, the :
characters do not need to be percent-encoded when encountered within a query, anyway. E.g.:
let queryItem = URLQueryItem(name: "scope", value: "channel:manage:polls+channel:read:polls")
var components = URLComponents(string: "https://example.com")
components?.queryItems = [
queryItem
]
guard let url = components?.url else { return }
print(url) // https://example.com?scope=channel:manage:polls+channel:read:polls
See RFC3986, in which, if you trace query
back to pchar
, you will see that :
does not need to be escaped.
But if there really was anything in that query that needed percent-encoding, URLQueryItem
and URLComponents
would take care of it for you. (The one exception is the +
character as discussed here; but I assume from your example that you didn’t want that escaped anyway.)
