Problem with signatures for query strings without values #65
Description
What is the correct way to generate the signature for requests with query string that has no key=value just a string without "=" sign for example https://domain/path?querystring
The service im connecting with for urls like that returns invalid signature error.
So who is not compliant with the RFC ? the service or the subscriber implementation ?
With one simple modification to the prepareParameters method i got the requests working, I can make a PR but i dont know it would be a valid change.
private function prepareParameters($data)
{
// Parameters are sorted by name, using lexicographical byte value
// ordering. Ref: Spec: 9.1.1 (1).
uksort($data, 'strcmp');
foreach ($data as $key => $value) {
if ($value === null) {
// unset($data[$key]); // current code
$data[$key] = ""; // modification needed to make requests with a valid sig
}
}
return $data;
}
