WC_API_Authentication::perform_oauth_authentication() │ private │ WC 2.1

Perform OAuth 1.0a "one-legged" (http://oauthbible.com/#oauth-10a-one-legged) authentication for non-SSL requests

This is required so API credentials cannot be sniffed or intercepted when making API requests over plain HTTP

This follows the spec for simple OAuth 1.0a authentication (RFC 5849) as closely as possible, with two exceptions:

1) There is no token associated with request/responses, only consumer keys/secrets are used

2) The OAuth parameters are included as part of the request query string instead of part of the Authorization header,

This is because there is no cross-OS function within PHP to get the raw Authorization header

Method of the class: WC_API_Authentication{}

No Hooks.

Return

Array.

Usage

// private - for code of main (parent) class only
