WC_API_Authentication::normalize_parameters() │ private │ WC 2.1

Normalize each parameter by assuming each parameter may have already been encoded, so attempt to decode, and then re-encode according to RFC 3986

Note both the key and value is normalized so a filter param like:

'filter[period]' => 'week'

is encoded to:

'filter%5Bperiod%5D' => 'week'

This conforms to the OAuth 1.0a spec which indicates the entire query string should be URL encoded

Method of the class: WC_API_Authentication{}

No Hooks.

Return

Array. normalized parameters

Usage

// private - for code of main (parent) class only
$result = $this->normalize_parameters( $parameters );

$parameters(array) (required)

un-normalized parameters
