2, generally do not have special needs use the following on the line

public function https_request($url, $data = null)
{
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    if(substr($url,0,5) == 'https'){
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); // 跳过证书检查
        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, true);  // 从证书中检查SSL加密算法是否存在
    }
    if (!empty($data)){
        curl_setopt($curl, CURLOPT_POST, 1);
        curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
    }
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    $output = curl_exec($curl);
    curl_close($curl);
    return $output;
}
