[Facebook Messenger Bot 問題] curl_errno = 60; curl_error = SSL certificate problem...問題

Facebook Messenger Webhook 驗證時出現以下訊息：

The URL couldn't be validated. Callback verification failed with the following errors: curl_errno = 60; curl_error = SSL certificate problem: unable to get local issuer certificate; HTTP Status Code = 200; HTTP Message = Connection established

表示 CA 認證檔案在開啟Server時沒有Load進來

以NodeJS 為例，將CA LOAD進來即可 ：
