Python API:DeviceCheck，状态代码：401，消息：无法验证授权令牌

我正在将JWT和所需的有效载荷提交给https://api.development.devicecheck.apple.com/v1/validate_device_token.然而，苹果的开发设备检查服务器总是返回http响应401-无法验证授权令牌

我正在跟踪为API请求生成令牌 并通过

curl -v -H 'Authorization: Bearer [signed token]' 
"https://api.appstoreconnect.apple.com/v1/apps"

那么服务器返回状态代码是200。但是使用APIDeviceCheck服务器总是返回https响应

https://api.devicecheck.apple.com/v1/validate_device_token

这是我的密码：

now = int(time.time()) 
expire_time = now + 20 * 60

HEADERS = {
    "alg": "ES256",
    "kid": kid,
    "typ": "JWT"
}

PAYLOAD = {
    'exp': expire_time,
    'iss': iss,
    'aud': "appstoreconnect-v1"
}

jwt_token = jwt.encode(PAYLOAD, private_key, algorithm='ES256', headers=HEADERS).decode('utf-8')

auth = 'Bearer {}'.format(jwt_token)

headers = {
    'Content-Type': 'application/x-www-form-urlencoded',
    'Authorization': auth
}

response = requests.get(
    'https://api.appstoreconnect.apple.com/v1/apps',
    headers=headers
)
print(response.status_code)
print(response.text)

request_file = '.../ValidateDeviceTokenRequest.json'
data = None
with open(request_file) as json_file:
    data = json.load(json_file)

data['timestamp'] = (now) * 1000

response = requests.post(
    'https://api.devicecheck.apple.com/v1/validate_device_token',
    data=json.dumps(data).encode(),
    headers=headers
)

print(response.status_code)
print(response.text)
