$token = $_POST['token']; $secret = 'ur secret'; $action = $_POST['action']; // now you need do a POST requst to google recaptcha server // url: https://www.google.com/recaptcha/api/siteverify // with data secret:$secret and response:$token (ask google how do a post request from PHP for details) // anweser from server (response from google recaptcha server) will be json object with field "success" (true/false) and "action" for comparison (==) and score (number from 0.0 - 1.0) 0.5 > is a bot and 0.5 < is a human... detailed here https://developers.google.com/recaptcha/docs/v3#api-response
你可以为每个请求指定动作名称(create_post,update_post,create_comment ……)
