Parse many query parameters without []

[LostKobrakai]

I'm looking into creating a webfinger server component and it seems plug cannot parse requests like:

GET /.well-known/webfinger?
        resource=acct%3Abob%40example.com&
        rel=http%3A%2F%2Fwebfinger.example%2Frel%2Fprofile-page&
        rel=http%3A%2F%2Fwebfinger.example%2Frel%2Fbusinesscard HTTP/1.1
    Host: example.com

Source

I'll only get the latter rel, but not both. What would be the recommended path of action here?

It is not possible out of the box. You would have to implement your own decoding or use the URI module:

iex(2)> URI.query_decoder("foo=1&bar=2&bar=3") |> Enum.into([])
[{"foo", "1"}, {"bar", "2"}, {"bar", "3"}]
