Getting an error "Error: SSL peer certificate or SSH remote key was not OK (CURLE_SSL_PEER_CERTIFICATE): SSL certificate problem: unable to get local issuer certificate"

        $host = $this->daletou.$qishu;
        $host = "https://www.baidu.com";

        $curl = new Curl();
        $curl->setUserAgent('Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/109.0');
        $curl->setOpt(CURLOPT_SSL_VERIFYPEER,0);//that is the key!
        $curl->get($host);

Resolution

不检查证书即可：CURLOPT_SSL_VERIFYPEER = 0 ;CURLOPT_SSL_HOST= 0;
