python - 使用 python,我无法从 Google Drive API v3 访问共享驱动器文件夹
问题描述
我可以获取 mydrive 文件夹,但无法从 Google Drive API 访问共享驱动器文件夹。这是我的代码。(与指南的代码几乎相同)
我按照指南,完成了“启用驱动器 API”,在 VScode 上执行 pip 命令,并将 credentials.json 放入工作目录。
(我没有收到任何错误,只有 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()
解决方案
请注意,API 具有用于确定共享驱动器项目是否显示在结果中的includeItemsFromAllDrives
参数。
Python API V3 包装器的列表方法实现中也包含此参数,调用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', [])
...
