我正在使用Microsoft Graph API（python3）。get_alerts()和get_secure_score_control_profiles()返回结果，但get_secure_score()返回'None'。
Azure门户显示安全分数，但尽管响应状态为200，函数仍返回。有指针吗？

def get_secure_score():

    base_url = 'https://graph.microsoft.com/beta/security/secureScores'
    #or 
    #base_url = 'https://graph.microsoft.com/v1.0/security/secureScores'
    secure_scores = MSGRAPH.get(base_url).json()
    print(secure_scores)
    secure_scores = secure_scores.json()
    print(secure_scores)

    if b'' in secure_scores:
        print("Please Sign-in using a on.microsoft.com account for demo data")
        secure_scores = None
    elif 'error' in secure_scores:
        secure_scores = None
    elif len(secure_scores.get('value')) > 0:
        secure_scores = secure_scores.get('value')[0]
    else:
        secure_scores = None
    return secure_scores

字符串

• 网址：https://graph.microsoft.com/beta/security/secureScores
• 响应：Response [200]
• 响应输出：

{
  '@odata.context': 'https://graph.microsoft.com/beta/$metadata#Security/secureScores', 
  'value': []
}
