此问题是由于访问令牌中的“Audience”声明无效引起的，可能由于其值与API或资源不匹配导致。解决方案是更新访问令牌中的“audience”声明，以确保其值与应用程序或API的受众匹配。示例代码片段：

import requests
import json

url = 'https://example.com/api'
token = 'Bearer ' + 'your_access_token_here'

headers = {
    'Authorization': token,
    'Content-Type': 'application/json'
}

response = requests.get(url, headers=headers)

if response.status_code == 401:
    # Access token is invalid
    print('Access token is invalid')
elif response.status_code == 200:
    data = json.loads(response.text)
    # Process the data
    print(data)
else:
    # Some other error occurred
    print('Error occurred: ' + str(response.status_code))
