使用 python，我无法从 Google Drive API v3 访问共享云端硬盘文件夹

Question

我可以获取 mydrive 文件夹，但无法从 Google Drive API 访问共享云端硬盘文件夹。这是我的代码。（几乎与这里的指南代码相同）

我按照指南进行操作，完成“启用 Drive API”，在 VScode 上执行 pip 命令，并将凭据.json 放入工作目录。

（我没有收到错误，只得到了 mydrive 的文件名列表或代码打印的“未找到文件”。）

from __future__ import print_function
import pickle
import os.path
from googleapiclient.discovery import build
from google_auth_oauthlib.flow import InstalledAppFlow
from google.auth.transport.requests import Request

# If modifying these scopes, delete the file token.pickle.
SCOPES = ['https://www.googleapis.com/auth/drive.metadata.readonly']

def main():
    """Shows basic usage of the Drive v3 API.
    Prints the names and ids of the first 10 files the user has access to.
    """
    creds = None
    # The file token.pickle stores the user's access and refresh tokens, and is
    # created automatically when the authorization flow completes for the first
    # time.
    if os.path.exists('token.pickle'):
        with open('token.pickle', 'rb') as token:
            creds = pickle.load(token)
    # If there are no (valid) credentials available, let the user log in.
    if not creds or not creds.valid:
        if creds and creds.expired and creds.refresh_token:
            creds.refresh(Request())
        else:
            flow = InstalledAppFlow.from_client_secrets_file(
                'credentials.json', SCOPES)
            creds = flow.run_local_server(port=0)
        # Save the credentials for the next run
        with open('token.pickle', 'wb') as token:
            pickle.dump(creds, token)

    service = build('drive', 'v3', credentials=creds)

    # Call the Drive v3 API
    results = service.files().list(
        pageSize=10, fields="nextPageToken, files(id, name)").execute()
    fields="nextPageToken, files(id, name)").execute()

    items = results.get('files', [])

    if not items:
        print('No files found.')
    else:
        print('Files:')
        for item in items:
            print(u'{0} ({1})'.format(item['name'], item['id']))

if __name__ == '__main__':
    main()

请注意，API 具有includeItemsFromAllDrives参数来确定共享云端硬盘项目是否显示在结果中。

Python API V3 包装器的列表方法实现中也包含此参数，调用该方法时需要包含该参数list()：

...

    service = build('drive', 'v3', credentials=creds)

    # Call the Drive v3 API
    results = service.files().list(
        pageSize=10, includeItemsFromAllDrives=True, supportsAllDrives=True, fields="nextPageToken, files(id, name)").execute()
    items = results.get('files', [])

...
