Magento 2 GET API request to external api

In magento 1 you can make get request like this: First Authorizing object-

public function authorize($url)
{
    $cookie = $this->getCookieDir();
    $user = $this->getApiUser();
    $curl = curl_init($url);

    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_USERAGENT, '.....-API-client/1.0');
    curl_setopt($curl, CURLOPT_POST, true);
    curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($user));
    curl_setopt($curl, CURLOPT_HEADER, false);
    curl_setopt($curl, CURLOPT_COOKIEFILE, $cookie);
    curl_setopt($curl, CURLOPT_COOKIEJAR, $cookie);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);

    $response = curl_exec($curl);

    curl_close($curl);
    return $response;
}

Then

public function get($url)
{
    $cookie = $this->getCookieDir();
    $curl = $this->initCh($url);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_USERAGENT, '.......-API-client/1.0');
    curl_setopt($curl, CURLOPT_HEADER, false);
    curl_setopt($curl, CURLOPT_COOKIEFILE, $cookie);
    curl_setopt($curl, CURLOPT_COOKIEJAR, $cookie);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);

    $out = curl_exec($curl); # Initiate a request to the API and stores the response to variable
    $code = curl_getinfo($curl, CURLINFO_HTTP_CODE);
    curl_close($curl);
    return $out;
}

Now in Magento 2

\Magento\Framework\HTTP\Client\Curl::get($uri); calls makeRequest();

In makeRequest(); curl_init() is called and all curlOption() are set. So there shouldn't be anymore need to do like in Magento 1? If so how this is how it should be done? -

/**
 * @param $url
 * @return void
 */
public function doGet($url){
    $user = $this->getApiUser();
    $this->_curl->setHeaders(CURLOPT_POSTFIELDS, http_build_query($user));
   //setting everything else
    $this->_curl->get($url);
}
