从响应URL中提取令牌 - Spotify的API [英] Extract token from response url - Spotify API

问题描述

我使用这个code获得来自Spotify的网络API令牌：

I'm using this code to get a token from Spotify's Web API:

<?php
$url = 'https://accounts.spotify.com/api/token';
$method = 'POST';

$credentials = "{Client ID}:{Client Secret}";

$headers = array(
        "Accept: */*",
        "Content-Type: application/x-www-form-urlencoded",
        "User-Agent: runscope/0.1",
        "Authorization: Basic " . base64_encode($credentials));
$data = 'grant_type=client_credentials';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

$response = curl_exec($ch);
?>

这导致此示出了在浏览器上：

That results in this showing up in the browser:

{"access_token":"{token}","token_type":"Bearer","expires_in":3600}

大！但我怎么从响应中提取{}令牌，并在该API的请求把它作为一个参数？例如，在请求 https://api.spotify.com/v1/users/ {} USER_ID /播放列表，需要在报头字段的标记。

Great! But how do I extract "{token}" from the response and use it as a parameter in a request to the API? For example in the request to https://api.spotify.com/v1/users/{user_id}/playlists which needs the token in the header field.

谢谢！

推荐答案

您需要取消code中的JSON：

You need to decode the JSON:

$response = json_decode($response, true);

那么你就必须用值的数组。

Then you'll have an array with the values.

$token = $response['access_token'];

另外，你缺少一个必要的选项来获得这样的回应：

Also, you're missing a necessary option to obtain the response in this way:

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

如果没有定义，你会得到一个布尔值，而不是响应。

If not defined, you will get a boolean value instead of the response.
