在Google驱动器中创建一个文件夹并将文件上传到该文件夹

Question

如何在Google驱动器中创建一个文件夹并将文件上传到该文件夹​​？ （在python中）

我已经尝试过Google教程，但这给了我错误

创建文件夹，无法正常工作，给我类似“未定义drive_service”的错误

file_metadata = {
    'title': 'Files',
    'mimeType': 'application/vnd.google-apps.folder'
}
file = drive_service.files().insert(body=file_metadata,
                                    fields='id').execute()
print 'Folder ID: %s' % file.get('id')

使用此代码来上传文件并且可以正常工作，如何修改该文件以将文件上传到文件夹（如果存在），如果不创建则上传。

import json
import requests
headers = {"Authorization": "Bearer Token"}

para = {
    "name": "index.jpeg",

}
files = {
    'data': ('metadata', json.dumps(para), 'application/json; charset=UTF-8'),
    'file': open("./index.jpeg", "rb")
}
r = requests.post(
    "https://www.googleapis.com/upload/drive/v3/files?uploadType=multipart",
    headers=headers,
    files=files
)
print(r.text)

这是我正在寻找的示例（它是一个独立的示例，但我认为您可以将其修改为自己的现有代码）：

from __future__ import print_function
from googleapiclient.discovery import build
from googleapiclient.http import MediaFileUpload
from httplib2 import Http
from oauth2client import file, client, tools

# If modifying these scopes, delete the file token.json.
SCOPES = 'https://www.googleapis.com/auth/drive.file'

def main():

    # Access the Drive service
    store = file.Storage('token.json')
    creds = store.get()
    if not creds or creds.invalid:
        flow = client.flow_from_clientsecrets('credentials.json', SCOPES)
        creds = tools.run_flow(flow, store)
    service = build('drive', 'v3', http=creds.authorize(Http()))


    # Check if folder exists (simply matching by name)
    folder_name = "Photos"

    folder_id = None
    query = "mimeType='application/vnd.google-apps.folder' and trashed=false and name='" + folder_name + "'"
    results = service.files().list(
        pageSize=1, q=query, fields="files(id, name)").execute()
    folders = results.get('files', [])

    if folders:
        folder_id = folders[0]['id']

    # If folder not found, then create it.
    else:
        file_metadata = {
            'name': folder_name,
            'mimeType': 'application/vnd.google-apps.folder'
        }
        folder_file = service.files().create(body=file_metadata,
                                            fields='id').execute()

        folder_id = folder_file.get('id')


    # Add file to folder.
    file_metadata = {
        'name': 'photo.png',
        'parents': [folder_id]
    }
    media = MediaFileUpload('photo.png',
                            mimetype='image/png',
                            resumable=True)

    image_file = service.files().create(body=file_metadata,
                                              media_body=media,
                                              fields='id').execute()

if __name__ == '__main__':
    main()
