Question

我已经创建了一个带有python函数的部署包，用于创建一个使用AWS Lambda的google驱动器文件夹。然后我尝试测试它，我得到一个错误：

    {
  "errorMessage": "main() takes from 0 to 1 positional arguments but 2 were given",
  "errorType": "TypeError",
  "stackTrace": [
    [
      "/var/runtime/awslambda/bootstrap.py",
      249,
      "handle_event_request",
      "result = request_handler(json_input, context)"
    ]
  ]
}

我的.zip中有2个主要文件。第一个文件包含main函数，另一个文件包含安全凭证，另一个文件夹和文件是lib。名为lambda_function.py的主文件，代码为：

from __future__ import print_function

import httplib2
import os

from apiclient import discovery
from oauth2client import client
from oauth2client import tools
from oauth2client.file import Storage

try:
    import argparse

    flags=argparse.ArgumentParser(parents=[tools.argparser]).parse_args()
except ImportError:
    flags=None

# If modifying these scopes, delete your previously saved credentials
# at ~/.credentials/drive-python-quickstart.json
SCOPES='https://www.googleapis.com/auth/drive.file'
CLIENT_SECRET_FILE='client_secret.json'
APPLICATION_NAME='Drive API Python Quickstart'


def get_credentials():
    """Gets valid user credentials from storage.

    If nothing has been stored, or if the stored credentials are invalid,
    the OAuth2 flow is completed to obtain the new credentials.

    Returns:
        Credentials, the obtained credential.
    """
    home_dir=os.path.expanduser('~')
    credential_dir=os.path.join(home_dir, '.credentials')
    if not os.path.exists(credential_dir):
        os.makedirs(credential_dir)
    credential_path=os.path.join(credential_dir,
                                 'drive-python-quickstart.json')

    store=Storage(credential_path)
    credentials=store.get()
    if not credentials or credentials.invalid:
        flow=client.flow_from_clientsecrets(CLIENT_SECRET_FILE, SCOPES)
        flow.user_agent=APPLICATION_NAME
        if flags:
            credentials=tools.run_flow(flow, store, flags)
        print('Storing credentials to ' + credential_path)
    return credentials

def main(drive_service=None):
    """Shows basic usage of the Google Drive API.

    Creates a Google Drive API service object and outputs the names and IDs
    for up to 10 files.
    """
    credentials=get_credentials()
    http=credentials.authorize(httplib2.Http())
    service=discovery.build('drive', 'v3', http=http)

    file_metadata={
        'name': 'Invoices',
        'mimeType': 'application/vnd.google-apps.folder'
    }
    file=service.files().create(body=file_metadata,
                                      fields='id').execute()
    print('Folder ID: %s' % file.get('id'))

if __name__ == '__main__':
    main()

并且我在AWS Lambda中的处理程序是lambda_function.main，如果我尝试测试我会收到错误。如果我在控制台上执行此操作，则会成功执行此代码并在google drive api中创建一个文件夹。也许谁知道我做错了什么？请帮助。

AWS Lambda处理程序有两个参数event和context，例如：

def lambda_handler(event, context):
