Question

我正在努力使用Spotify API来从他们的回复中获取封面艺术网址。在这个例子中，我试图从Michael Jackson的“Billie Jean”那里获得封面艺术。这看起来真的很直接，但我根本就不是专家 - 我只是在玩，看看我是否可以解决这个问题。

访问以下网址：

https://embed.spotify.com/oembed/?url=spotify:track:5ChkMS8OtdzJeqyybCc9R5&format=json&callback=spotify

返回以下JSON响应：

  spotify({"provider_url":"https:\/\/www.spotify.com","version":"1.0","thumbnail_width":300,"height":380,"thumbnail_height":300,"title":"Michael Jackson - Billie Jean - Single Version","width":300,"thumbnail_url":"https:\/\/d3rt1990lpmkn.cloudfront.net\/cover\/e337f3661f68bc4d96a554de0ad7988d65edb25a","provider_name":"Spotify","type":"rich","html":"<iframe src=\"https:\/\/embed.spotify.com\/?uri=spotify:track:5ChkMS8OtdzJeqyybCc9R5\" width=\"300\" height=\"380\" frameborder=\"0\" allowtransparency=\"true\"><\/iframe>"});

我要做的是让PHP脚本拉出thumbnail_url并在文档中回显它。但是，我只收到错误消息。任何人都可以帮助我，并指出我做错了什么？

到目前为止，这是我的脚本：

<?php
$track = "spotify:track:5ChkMS8OtdzJeqyybCc9R5";
$url = "https://embed.spotify.com/oembed/?url=".$track."&format=json&callback=spotify";
$get_data  = file_get_contents($url);
$get_json  = json_decode($get_data);

$cover = $get_json->spotify->thumbnail_url;

echo $cover;
?>

Answer 1

file_get_contents不起作用的原因是，如果启用错误报告，您将看到错误：

警告：file_get_contents（）[function.file-get-contents]：无法执行找到包装＆＃34; https＆＃34; - 你忘了启用它吗？配置PHP？

的 See answers related to that error here.

所以最简单的解决方案就是使用cURL代替和 CURLOPT_SSL_VERIFYHOST＆amp; CURLOPT_SSL_VERIFYPEER属性设置为false。

因此代码为： See in action!

<?php $track = "spotify:track:5ChkMS8OtdzJeqyybCc9R5"; $url = "https://embed.spotify.com/oembed/?url=".$track."&format=json"; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (compatible; curl)"); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); $json = curl_exec($ch); curl_close($ch); $json = json_decode($json); $cover = $json->thumbnail_url; //https://d3rt1990lpmkn.cloudfront.net/cover/e337f3661f68bc4d96a554de0ad7988d65edb25a echo $cover; //Debug - Complete response echo '<pre>'.print_r($json, true).'</pre>'; /* stdClass Object ( [provider_url] => https://www.spotify.com [version] => 1.0 [thumbnail_width] => 300 [height] => 380 [thumbnail_height] => 300 [title] => Michael Jackson - Billie Jean - Single Version [width] => 300 [thumbnail_url] => https://d3rt1990lpmkn.cloudfront.net/cover/d45aa25bbd45872c0b1e97223af57fe94588820a [provider_name] => Spotify [type] => rich [html] => ) */

您似乎需要设置用户代理，而不是100％，因为我还没有检查过文档，但设置带有CURL的用户代理可以让我接收数据。请尝试以下方法：

<?php
$track = "spotify:track:5ChkMS8OtdzJeqyybCc9R5";
$url = "https://embed.spotify.com/oembed/?url=".$track."&format=json";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:x.x.x) Gecko/20041107 Firefox/x.x");
$output = curl_exec($ch);
curl_close($ch);

$get_json  = json_decode($output);
$cover     = $get_json->thumbnail_url;
echo $cover;

使用CURL可以更精细地处理您的请求。在此示例中，我们正在设置用户代理。

这就是我在Python中的表现，这对我来说效果很好。我看到的主要区别是网址中的&callback=，这在我写这篇文章时似乎是必需的。

import requests
def getArt(spTrackURL,x=False):
    """
        Takes a uri to a spotify track
        -> Use uri to query Spotify web service for album art path
        -> modify art path to produce 300 px image (larger than default, no logo) 
        -> return art path as string
    """
    if (not x):
        log("getArt","for '" + spTrackURL + "' -> Getting cover art from Spotify")
    spEmbedUrl = 'https://embed.spotify.com/oembed/?url=' + spTrackURL + '&callback=?'
    try:
        r = requests.get(spEmbedUrl)
        while (r.text == ''):
            time.sleep(1)
        t = r.text.split(',')
        for i in t:
            if (i.find('thumbnail_url') != -1):
                t = i
        t = t.replace('"thumbnail_url":"','').replace('"', '').replace('\\','').replace('cover','300')
        #print t
    except:
        t = ''
        #print 'something bad happened when getting art, trying again'
        t = getArt(spTrackURL, True)
    return t
