使用microsoft graph API获取preferred_username

import requests
from msal import ConfidentialClientApplication

# 配置客户端信息
client_id = 'your-client-id'
client_secret = 'your-client-secret'
tenant_id = 'your-tenant-id'
authority = f'https://login.microsoftonline.com/{tenant_id}'

# 创建应用实例
app = ConfidentialClientApplication(client_id, authority=authority, client_credential=client_secret)

# 获取访问令牌
result = app.acquire_token_for_client(scopes=["https://graph.microsoft.com/.default"])
access_token = result['access_token']

# 使用访问令牌调用 Microsoft Graph API
headers = {
    'Authorization': f'Bearer {access_token}',
    'Content-Type': 'application/json'
}

response = requests.get('https://graph.microsoft.com/v1.0/me', headers=headers)

if response.status_code == 200:
    user_info = response.json()
    preferred_username = user_info.get('preferredUsername')
    print(f'Preferred Username: {preferred_username}')
else:
    print(f'Error: {response.status_code} - {response.text}')
