为什么我从 python 中的请求中得到不正确的响应 json

Question

我正在尝试使用 python 自动添加歌曲以进行 spotify。 在代码中，我尝试使用 song_name 和艺术家姓名搜索歌曲，并使用 spotify api 获取歌曲的 URI。 (https://developer.spotify.com/documentation/web-api/reference/search/search/)

但是我得到的响应是无效的，即它不返回带有 uris 的歌曲列表，它只是返回查询或我发送到 API 的请求。

例如 {'tracks': {'href': 'https://api.spotify.com/v1/search?query=track%3AYEAH+RIGHT+artist%3AJoji&type=track&offset=0&limit=20', 'items': [], 'limit': 20, 'next': None, 'offset': 0, 'previous': None , '总计': 0}}

def get_spotify_uri(self, song_name, artist):
    """Search For the Song"""
    query = "https://api.spotify.com/v1/search?q=track:{}%20artist:{}&type=track".format(
        song_name,
        artist
    )
    response = requests.get(
        query,
        headers={
            "Content-Type": "application/json",
            "Authorization": "Bearer {}".format(spotify_token)
        }
    )
    response_json = response.json()
    print(response_json)
    songs = response_json["tracks"]["items"]

    # only use the first song
    uri = songs[0]["uri"]

    return uri            



Error: response
{'tracks': {'href': 'https://api.spotify.com/v1/search?query=track%3ANext+%28Album+Version%29+artist%3AThe+Weeknd&type=track&offset=0&limit=20', 'items': [], 'limit': 20, 'next': None, 'offset': 0, 'previous': None, 'total': 0}}

我发布答案是因为我无法在评论中包含整个内容。我只想说我成功使用了下面的准系统代码，但是使用了urllib，鉴于您使用了requests 库，这可能不是您想要的。也许它可以用于比较目的（在 python 3.8 中测试）：

import urllib.request, urllib.parse
import base64, json

# fill with your own
client_id = b"insert_here_your_client_id"
client_secret = b"insert_here_your_client_secret"

# ask for authorization
query = "https://accounts.spotify.com/api/token"
postdata = urllib.parse.urlencode({"grant_type": "client_credentials"})
postheaders = {'Authorization': "Basic "+base64.b64encode( client_id+b':'+client_secret ).decode('latin-1')}
req = urllib.request.Request(query, data=postdata.encode('latin-1'), headers=postheaders)
req = urllib.request.urlopen(req).read().decode('latin-1')
req = json.loads(req)

# do the search query
query = "https://api.spotify.com/v1/search?q=track:Castles%20artist:Freya&type=track"
req = urllib.request.Request(query, data=None, headers={'Authorization': "Bearer "+req['access_token']})
req = urllib.request.urlopen(req).read().decode('latin-1')
print(req)
