在 PHP 中，如何向使用与我的网站 (https) 不同协议 (http) 的另一个网站发出 curl 请求？

Question

I want to do a curl request from my https website to another website that only uses http. How do I do that? The code below only works if the protocols are the same. How do I modify these two examples to make it work across the different protocols, if possible? Thank you for your help.

<?php
    // create curl resource 
    $ch = curl_init(); 

    // set url 
    curl_setopt($ch, CURLOPT_URL, 'http://www.anotherwebsite.com'); 

    //return the transfer as a string 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 

    // $output contains the output string 
    $output = curl_exec($ch); 

    // close curl resource to free up system resources 
    curl_close($ch);

    // OR I WANT TO USE
    $result = file_get_contents('http://www.anotherwebsite.com');
?>

I can't think of any reason why it should be necessary. But if you want to use the same protocol, you can check $_SERVER['HTTPS'] .

$protocol = empty($_SERVER['HTTPS']) ? 'http' : 'https';
$url = "$protocol://www.anotherwebsite.com";
