How to get protocol(http/https) of the incoming request from the laravel HTTP request class?

Question

In my new application API, I have to check the request from the third party URL's should be in https. If it is not https, I have to return the message as "connection is not secure'. Can anyone help me?

Daniel Tran's answer is correct just for information HTTPS type requests have an extra field HTTPS on requests. Sometimes this field can be equal to off too but nothing else.

so you can just write a code like

if (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off') { 
  doSomething();
}

Laravel Request Class also inherited something totally similar from symphony. Which You can find under;

vendor/symfony/http-foundatiton/Request.php

public function isSecure()
    {
        if ($this->isFromTrustedProxy() && self::$trustedHeaders[self::HEADER_CLIENT_PROTO] && $proto = $this->headers->get(self::$trustedHeaders[self::HEADER_CLIENT_PROTO])) {
            return in_array(strtolower(current(explode(',', $proto))), array('https', 'on', 'ssl', '1'));
        }

        $https = $this->server->get('HTTPS');

        return !empty($https) && 'off' !== strtolower($https);
    }
