Configure OAuth 2.0 Authentication for REST

Demonstrates Rest.SetAuthOAuth2, which associates an OAuth2 provider containing a valid access token so Chilkat adds the bearer token to the Authorization header.

Background. OAuth 2.0 bearer-token authentication attaches the access token to each request. The token is typically obtained separately through an OAuth 2.0 authorization flow before being assigned to the provider.

$rest = new Rest();

    $rest->Connect('example.com', 443, $bTls, $bAutoReconnect);

    // Configure OAuth 2.0 bearer-token authentication.  The provider must contain a valid access token.
    $oauth2 = new OAuth2();
    // Normally you would not hard-code secrets in source.  You should instead obtain them from an
    // interactive prompt, environment variable, or a secrets vault.
    $oauth2->AccessToken = 'OAUTH2_ACCESS_TOKEN';

    // Associate the provider so Chilkat adds the bearer token to the Authorization header.
