如何在Gmail API中正确设置" in -Reply-To“和"Reference”标头

import base64
from googleapiclient.discovery import build
from googleapiclient.errors import HttpError
from google.oauth2.credentials import Credentials

# 设置Gmail API的访问凭证
credentials = Credentials.from_authorized_user_file('credentials.json')
service = build('gmail', 'v1', credentials=credentials)

# 获取被回复邮件的Message-ID
def get_message_id():
    try:
        response = service.users().messages().list(userId='me', q='subject:"原始邮件的主题"').execute()
        message_id = response['messages'][0]['id']
        return message_id
    except HttpError as error:
        print(f'An error occurred: {error}')

# 设置回复邮件的标头信息
def set_reply_headers():
    message_id = get_message_id()
    if message_id:
        reply_message = {
            'inReplyTo': message_id,
            'references': [message_id]
        }
        try:
            response = service.users().messages().send(userId='me', body=reply_message).execute()
            print('Reply sent successfully.')
        except HttpError as error:
            print(f'An error occurred: {error}')
