我需要从tiktok中获取活动数据，广告组和广告，这是我试过的

import requests

url = "https://business-api.tiktok.com/open_api/v1.3/campaign/get/"

access_token = "your_access_token"

headers = {
    "Authorization": f"Bearer {access_token}"
}

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

if response.status_code == 200:
    print(response.json()) 
else:
    print(f"Failed to fetch ad campaigns. Status code: {response.status_code}")
    print(None)

字符串
但这会产生如下误差

{'code': 40104, 'message': 'Access token is null, you should set it in http header with key Access-Token.', 'request_id': '', 'data': {}}
