Question

所以我连接到最后一个fm API，信息看起来像这个

{"topartists":{"artist":[{"name":"Bee Gees","mbid":"bf0f7e29-dfe1-416c-b5c6-f9ebc19ea810","url":"https://www.last.fm/music/Bee+Gees","streamable":"0","image":[{"#text":"https://lastfm-img2.akamaized.net/i/u/34s/1df682d5ba6e45db843c45a336170470.png","size":"small"},{"#text":"https://lastfm-img2.akamaized.net/i/u/64s/1df682d5ba6e45db843c45a336170470.png","size":"medium"},{"#text":"https://lastfm-img2.akamaized.net/i/u/174s/1df682d5ba6e45db843c45a336170470.png","size":"large"},{"#text":"https://lastfm-img2.akamaized.net/i/u/300x300/1df682d5ba6e45db843c45a336170470.png","size":"extralarge"},{"#text":"https://lastfm-img2.akamaized.net/i/u/300x300/1df682d5ba6e45db843c45a336170470.png","size":"mega"}],"@attr":{"rank":"1"}}

在我的PHP代码中，我使用

        class LastFm{

    private $api_key;
    const url = 'http://ws.audioscrobbler.com/2.0/';

    function __construct($api_key){
        $this->api_key = $api_key;
    }

    function call($method,$params=array()){
        $lastfm = self::url.'?method='.$method.'&format=json&api_key='.$this->api_key;
        foreach($params as $key => $value){
            $lastfm .= '&'.$key.'='.urlencode($value);
        }
        $json = file_get_contents($lastfm);
        return json_decode($json, true);
    }

}

?>
<?php

$lastfm = new LastFm('63692beaaf8ba794a541bca291234cd3');




$tracks = $lastfm->call('tag.gettopartists&tag=disco');
foreach($tracks['topartists']['artist'] as $track){


?>

成功返回艺术家姓名。但是我如何获得中等大小的图像？我试过了 -

  `echo $artist['image'];`

但没有任何回报。

Answer 1

echo '<img src="'.$track['image'][0]['#text'].'">';是您正在寻找的。

0是$track['image']数组中的索引，您可能希望根据所需的图像大小进行更改...或者，您可以循环它并填充新的图像数组

$images = [];
foreach($track['image'] as $image){
    $images[] = [ $image['size']=>$image['#text'] ];
}

echo '<img src="'.$images['small'].'"/>;

连接到Lastfm Api，可以获取除艺术家图像之外的所有信息
