Class Oauth
Oauth 1 authentication strategy for Cake\Http\Client
This object does not handle getting Oauth access tokens from the service provider. It only handles make client requests after you have obtained the Oauth tokens.
Generally not directly constructed, but instead used by {@link \Cake\Http\Client} when $options['auth']['type'] is 'oauth'

_buildAuth(array $data): stringBuilds the Oauth Authorization header value.
Parameters
-
array$data The oauth_* values to build
Returns
string_encode() ¶ protected
_encode(string $value): stringURL Encodes a value based on rules of rfc3986
Parameters
-
string$value Value to encode.
Returns
string_hmacSha1() ¶ protected
_hmacSha1(Cake\Http\Client\Request $request, array $credentials): stringUse HMAC-SHA1 signing.
This method is suitable for plain HTTP or HTTPS.

_normalizedParams() ¶ protected
_normalizedParams(Cake\Http\Client\Request $request, array $oauthValues): stringSorts and normalizes request data and oauthValues
Section 9.1.1 of Oauth spec.
- URL encode keys + values.
- Sort keys & values by byte value.
