如何播放指定播放列表中的歌曲 (Spotify API)

Question

我想在 python 中使用 spotify API 播放给定播放列表中的所有歌曲。我有访问令牌和所需的东西，但得到的响应是 403，第一种方法 find_songs returns 我的播放列表 returns 响应是 200，但第二种方法不是方法

class SaveSongs:
def __init__(self):
    self.user_id = spotify_user_id
    self.spotify_token = ""
    self.playlist_id = playlist_id
    self.tracks = ""
    self.new_playlist_id = ""
    self.device_id = "DESKTOP-9UBFPPN"

def find_songs(self):
    print("Finding songs in your playlist...")
    query = "https://api.spotify.com/v1/playlists/{}/tracks".format(
        playlist_id)
    response = requests.get(query,
                            headers={"Content-Type": "application/json",
                                     "Authorization": "Bearer {}".format(self.spotify_token)})
    response_json = response.json()
    print(response)

def call_refresh(self):
    print("Refreshing token")
    refreshCaller = Refresh()
    self.spotify_token = refreshCaller.refresh()
    self.find_songs()

def playSong(self): #issue here
    query = "https://api.spotify.com/v1/me/player/play"
    response = requests.put(query,
                            headers={"Content-Type": "application/json",
                                    "Authorization": "Bearer {}".format(self.spotify_token)}, data={
        "context_uri": "spotify:playlist:7mnkglhHfzZRYFRG72zCMd"
    })

    print(response)

a = SaveSongs()
a.call_refresh()
a.playSong()

Refresh.py:

class Refresh:

def __init__(self):
    self.refresh_token = refresh_token
    self.base_64 = base_64

def refresh(self):

    query = "https://accounts.spotify.com/api/token"

    response = requests.post(query,
                             data={"grant_type": "refresh_token",
                                   "refresh_token": refresh_token},
                             headers={"Authorization": "Basic " + base_64})

    response_json = response.json()
    print(response_json)

    return response_json["access_token"]


a = Refresh()
a.refresh()

cURL 命令

curl -H "Authorization: Basic " -d grant_type=authorization_code -d code= -d redirect_uri=https%3A%2F%2Fgithub.com%2FRohith-JN https://accounts.spotify.com/api/token

获取获取 curl 命令代码的请求：

https://accounts.spotify.com/authorize?client_id=&response_type=code&redirect_uri=https%3A%2F%2Fgithub.com%2FRohith-JN&scope=playlist-modify-public%20playlist-modify-private%20user-modify-playback-state

过期的访问令牌：

Answer 1

我相信你是想打 this API。如果您检查 Authorization Scopes Guide，它表明您在请求访问令牌时需要包括所需的“范围”。

这就是大多数 Oauth 系统的工作方式。要访问受保护的资源，您首先要获得访问令牌。但是您还声明您想说，阅读资源 XYZ。您获得的访问令牌将具有受限的权限，只能执行您想要执行的操作（即使您作为用户拥有许多其他操作的权限）。

向下滚动到 the scope that you need，并在请求访问令牌时包含此范围。我相信这可以解决你的问题。

嗯，我怎么知道如何搜索这个范围？我查找了您要访问的 URI，并查找了该 URI 的范围。

Answer 2

我发现问题不在于我的代码，对于某些调用，例如 play/pause，增加或减少音量需要 Spotify 高级帐户。
