【中文标题】通过 Spotify API 获取封面艺术【英文标题】:Fetching cover art via the Spotify API 【发布时间】:2014-06-18 08:46:18 【问题描述】:我正在尝试使用 Spotify API 来从他们的响应中提取封面艺术 URL。在这个例子中,我试图从迈克尔杰克逊的“Billie Jean”中获取封面艺术。这似乎很简单,但我根本不是专家 - 我只是在玩弄看看我能不能解决这个问题。
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 脚本提取 thumbnail_url
并在文档中回显它。但是,我只收到错误消息。谁能帮助我,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;
?>
【问题讨论】:
【参考方案1】:file_get_contents 不起作用的原因是,如果您启用错误报告,您将看到错误:
警告:file_get_contents() [function.file-get-contents]:无法 找到包装器“https” - 您是否忘记启用它 配置PHP?
See answers related to that error here.
因此,无需摆弄 PHP 的最简单的解决方案是使用 cURL 代替 将 CURLOPT_SSL_VERIFYHOST
和 CURLOPT_SSL_VERIFYPEER
属性设置为 false
。
所以代码是: 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>';
/*

非常感谢,洛兹!这对我帮助很大。我现在对这些事情有了更好的理解 :-) 再次感谢!【参考方案2】:看起来您需要设置一个用户代理,而不是 100%,因为我没有检查文档,但是使用 CURL 设置一个用户代理可以让我接收数据。请尝试以下操作:
<?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。在这个例子中,我们设置了一个用户代理。

感谢您的提示。奇迹般有效! :) 真的很感激!【参考方案3】:这就是我在 Python 中的做法,这对我来说效果很好。我看到的主要区别是网址中的&callback=
,在我写这篇文章的时候似乎是必需的。
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
