问题 I'm trying to use PHP's Oauth module to interact with Etsy's API. Following Etsy's docs, I have <?php if (!extension_loaded('oauth')) { throw new Exception('Oauth not loaded.'); } $oauth = new OAuth("foobar-key", "foobar-secret"); $req_token = $oauth->getRequestToken( "https://openapi.etsy.com/v2/oauth/request_token?scope=email_r%20listings_r", "oob", "GET" ); This works fine when run with php7.2: php7.2 etsy-oauth.php ...
