PHP/Curl：如何显示来自外部 API 的图像？

Question

I want to display images from the website "https://picsum.photos/v2/list", however when I try to echo out the url, I get a 404 error. What am I missing from my code? This is what I have so far:

<?php
$url = "https://picsum.photos/v2/list";
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$picture = json_decode(curl_exec($curl), true);
curl_close($curl);
?>

<?php
  if(!empty($picture)){
    echo 'Picture:';
    foreach($picture as $post){
      echo '<img src= "'. $post["url"] .'" />';
    }
  }
?>

Your code is working fine in my PHP Server but you have one problem that you are using "url" element of array which is url for full page not for single image file. But There is another element in your api response named "download_url" which return image, so if you change your code to below.

<?php
$url = "https://picsum.photos/v2/list";
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$picture = json_decode(curl_exec($curl), true);
curl_close($curl);
?>

<?php
  if(!empty($picture)){
    echo 'Picture:';
    foreach($picture as $post){
      echo '<img src= "'. $post["download_url"] .'" />';
    }
  }
?>
