php curl 携带CA证书请求

最近在开发一个微信小微商户项目,API请求都需要携带微信的CA证书进行请求,直接上代码,就当自己备份一下

private function wx_httpPost($url, $data, $cert, $key, $headers = 0)

    {

        $ip = rand(0, 255) . '.' . rand(0, 255) . '.' . rand(0, 255) . '.' . rand(0, 255);

        $UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; SLCC1; .NET CLR 2.0.50727; .NET CLR 3.0.04506; .NET CLR 3.5.21022; .NET CLR 1.0.3705; .NET CLR 1.1.4322)";

        if (!$headers) {

            $headers = ['X-FORWARDED-FOR:' . $ip . '', 'CLIENT-IP:' . $ip . ''];

        }

        $ch = curl_init();

        curl_setopt($ch, CURLOPT_URL, $url);

        curl_setopt($ch, CURLOPT_TIMEOUT, 300);

        curl_setopt($ch, CURLOPT_POST, 1);

        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

        curl_setopt($ch, CURLOPT_USERAGENT, $UserAgent);

        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);

        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

        curl_setopt($ch, CURLOPT_SSLCERTTYPE, 'PEM');

        curl_setopt($ch, CURLOPT_SSLCERT, $cert);

        curl_setopt($ch, CURLOPT_SSLKEYTYPE, 'PEM');

        curl_setopt($ch, CURLOPT_SSLKEY, $key);

        $output = curl_exec($ch);

        curl_close($ch);

        return $output;

    }
