### 使用 Python 通过 Outlook API 发送通知或邮件 为了使用 Python 通过 Outlook API 发送通知或邮件，需要遵循 OAuth2 认证流程来获取访问令牌，并利用 Microsoft Graph API 进行操作。以下是具体方法： #### 安装所需库 首先安装必要的 Python 库 `requests` 和 `msal` 来处理 HTTP 请求和 Azure Active Directory (Azure AD) 的身份验证。 ```bash pip install requests msal ``` #### 获取应用注册信息 前往 [Microsoft App Registration Portal](https://portal.azure.com/#blade/Microsoft_AAD_IAM/ActiveDirectoryMenuBlade/Applications)，创建一个新的应用程序并记录下客户端ID、租户ID以及重定向URI等必要参数。 #### 编写代码实现发送邮件功能 下面是一段完整的 Python 脚本用于向指定收件人发送简单纯文本邮件[^1]。 ```python import os import json import requests from msal import ConfidentialClientApplication, PublicClientApplication def get_access_token(client_id, client_secret, tenant_id): authority_url = f'https://login.microsoftonline.com/{tenant_id}' app = ConfidentialClientApplication( client_id=client_id, client_credential=client_secret, authority=authority_url) result = None accounts = app.get_accounts() if not accounts: scopes = ['https://graph.microsoft.com/.default'] try: result = app.acquire_token_for_client(scopes=scopes) if "access_token" in result: return result['access_token'] except Exception as e: print(f'Error acquiring token: {e}') else: raise ValueError('Unexpected account found.') def send_email(access_token, recipient_email, subject, body_content): graph_api_endpoint = 'https://graph.microsoft.com/v1.0/me/sendMail' headers = { 'Authorization': f'Bearer {access_token}', 'Content-Type': 'application/json' } email_data = { "message": { "subject": subject, "body": { "contentType": "Text", "content": body_content }, "toRecipients": [ {"emailAddress": {"address": recipient_email}} ] } } response = requests.post(graph_api_endpoint, headers=headers, data=json.dumps(email_data)) if response.status_code == 202: print("Email sent successfully.") else: print(f"Failed to send email with status code {response.status_code}: {response.text}") if __name__ == '__main__': CLIENT_ID = '<your-client-id>' CLIENT_SECRET = '<your-client-secret>' TENANT_ID = '<your-tenant-id>' access_token = get_access_token(CLIENT_ID, CLIENT_SECRET, TENANT_ID) RECIPIENT_EMAIL = "<recipient-email>" SUBJECT = "Test Email from Python" BODY_CONTENT = "This is a test message." send_email(access_token, RECIPIENT_EMAIL, SUBJECT, BODY_CONTENT) ``` 此脚本实现了两个主要函数：一个是用来请求访问令牌 (`get_access_token`)；另一个则是实际调用 Microsoft Graph API 来发送邮件(`send_email`)。需要注意的是，在生产环境中应当妥善保管这些敏感信息而不是硬编码到源码里[^4]。
