Spotify API“未提供令牌”错误代码401

在使用Spotify API提取用户热门曲目时,我一直收到401个错误。代码如下所示:

import json
from requests import post, get
import base64

def get_token():
    auth_string = CLIENT_ID + ":" + CLIENT_SECRET
    auth_bytes = auth_string.encode("utf-8")
    auth_base64 = str(base64.b64encode(auth_bytes), "utf-8")

    url = "https://accounts.spotify.com/api/token"
    headers = {
        "Authorization" : "Basic " + auth_base64,
        "Content-Type" : "application/x-www-form-urlencoded"
    } 

    data = {"grant_type" : "client_credentials"}
    result = post(url, headers=headers, data=data)
    json_result = json.loads(result.content)
    token = json_result["access_token"]
    return token

def searchArtist(token, artist_name):
    url = "https://api.spotify.com/v1/search"
    headers = {
        "Authorizations" : "Bearer " + token
    }
    query = f"?q={artist_name}&type=artist&limit=1"
    query_url = url + query
    result = get(query_url, headers=headers)
    data = result.json()
    print(data)

myToken = get_token()
searchArtist(myToken, "ACDC")

显示以下错误:

{“错误”:{“状态”:401,“消息”:“未提供令牌”}}

我是不是错过了什么?

我原以为曲目会出现。我看过Spotify API文档,我一直在做正确的事情。也许我错过了什么,或者什么是真实的,我说不清。
