javascript - 通过 echo PHP 查找 deezer API 图稿

Question

我在论坛中找到了这段代码 php，我尝试适应我的意图，在 this link 中有一个 JSON，其中包含我们搜索的艺术家的信息。但我只想提取这个函数 cover_xl

"cover_xl":"https:\/\/cdns-images.dzcdn.net\/images\/cover\/1c7a7c081a1e7787321f81a889e9f7b8\/1000x1000-000000-80-0-0.jpg"

我尝试了很多方法都没有结果，所以才来寻求你的帮助。我还留下了代码以尝试帮助解决问题。

<?php 
    $query = 'https://api.deezer.com/2.0/search?q=sam smith'; 
    $file = file_get_contents($query); 
    $parsedFile = json_decode($file); 
    $albumart = $parsedFile->data[0]->artist->picture[cover_xl]; 
?>

Answer 1

使用以下代码我做了你想要的事情:

<?php

$url = 'https://api.deezer.com/2.0/search?q=sam%20smith';
$jsonStr = file_get_contents($url);
$jsonArr = json_decode($jsonStr, true);

$coverXlCollection = array();

foreach ($jsonArr['data'] as $row) {
    $coverXlCollection[] = $row['album']['cover_xl'];
}

echo '<pre>'.print_r($coverXlCollection, true).'</pre>';

?>

结果如下:

Array

我对您的代码做了一些修改，并使用了带有第二个参数true的json_decode()函数。在这种情况下，您的结果是数组而不是对象。

干杯。
