我无法通过 Python API 获取 google-drive file-delete() 方法。

它坏了。

我提供一些关于我的设置的信息:

  • Ubuntu 16.04
  • Python 3.5.2(默认,2018 年 11 月 12 日,13:43:14)
  • google-api-python-client (1.7.9)
  • 谷歌验证 (1.6.3)
  • google-auth-httplib2 (0.0.3)
  • google-auth-oauthlib (0.3.0)

下面,我列出了一个可以重现该错误的 Python 脚本:

"""
googdrive17.py

This script should delete files named 'hello.txt'

Ref:
https://developers.google.com/drive/api/v3/quickstart/python
https://developers.google.com/drive/api/v3/reference/files

Demo (Ubuntu):
sudo apt install python3-pip
sudo pip3 install --upgrade google-api-python-client
sudo pip3 install --upgrade google-auth-httplib2
sudo pip3 install --upgrade google-auth-oauthlib

python3 googdrive17.py
"""

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

# I s.declare a very permissive scope (for training only):
SCOPES = ['https://www.googleapis.com/auth/drive']

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 fh:
creds = pickle.load(fh)
# 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()
# Save the credentials for the next run
with open('token.pickle', 'wb') as token:
pickle.dump(creds, token)

# I s.create a file so I can upload it:
with open('/tmp/hello.txt','w') as fh:
fh.write("hello world\n")
# From my laptop, I s.upload a file named hello.txt:
drive_service = build('drive', 'v3', credentials=creds)
file_metadata = {'name': 'hello.txt'}
media = MediaFileUpload('/tmp/hello.txt', mimetype='text/plain')
create_response = drive_service.files().create(body=file_metadata,
media_body=media,
fields='id').execute()
file_id = create_response.get('id')
print('new /tmp/hello.txt file_id:')
print(file_id)

# Q: With googleapiclient, how to filter files list()-response?
# A1: https://developers.google.com/drive/api/v3/reference/files/list
# A2: https://developers.google.com/drive/api/v3/search-files

list_response = drive_service.files().list(
orderBy = "createdTime desc",
q = "name='hello.txt'",
pageSize = 22,
fields = "files(id, name)"
).execute()

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

if items:
for item in items:
print('I will try to delete this file:')
print(u'{0} ({1})'.format(item['name'], item['id']))
del_response = drive_service.files().delete(fileId=item['id'])
print('del_response.body:')
print( del_response.body)
print('I will try to emptyTrash:')
trash_response = drive_service.files().emptyTrash()
print('trash_response.body:')
print( trash_response.body)
else:
print('hello.txt not found in your google-drive account.')

当我运行脚本时,我看到类似于下面列出的输出:

$ python3 googdrive17.py
new /tmp/hello.txt file_id:
1m8nKOfIeB0E5t60F_-9bKwIJds8PSvYY
I will try to delete this file:
hello.txt (1m8nKOfIeB0E5t60F_-9bKwIJds8PSvYY)
del_response.body:
None
I will try to delete this file:
hello.txt (1Ow4fcUBgEYUy3ezYScDKlLSMbp-hyOLT)
del_response.body:
None
I will try to delete this file:
hello.txt (1TiUrLgQdY1Cb9w0UWHjnmj7HZBaFsKcp)
del_response.body:
None
I will try to emptyTrash:
trash_response.body:
None
$

我看到其中两个 API 调用运行良好:

  • 文件列表()
  • files.create()

两个调用似乎中断了:

  • 文件.删除()
  • files.emptyTrash()

不过,也许我调用它们不正确?

最佳答案

这个修改怎么样?

首先Files: delete method的官方文档和 Files: emptyTrash method说如下。

If successful, this method returns an empty response body.

这样,当文件被删除,垃圾被清除时,返回的del_responsetrash_response为空。

修改后的脚本:

根据您的问题,我可以理解 files.list()files.create() 有效。所以我想提出files.delete()files.emptyTrash()的修改点。请按如下方式修改您的脚本。

从:
for item in items:
print('I will try to delete this file:')
print(u'{0} ({1})'.format(item['name'], item['id']))
del_response = drive_service.files().delete(fileId=item['id'])
print('del_response.body:')
print( del_response.body)
print('I will try to emptyTrash:')
trash_response = drive_service.files().emptyTrash()
print('trash_response.body:')
print( trash_response.body)
到:
for item in items:
print('I will try to delete this file:')
print(u'{0} ({1})'.format(item['name'], item['id']))
del_response = drive_service.files().delete(fileId=item['id']).execute() # Modified
print('del_response.body:')
print(del_response)
print('I will try to emptyTrash:')
trash_response = drive_service.files().emptyTrash().execute() # Modified
print('trash_response.body:')
print(trash_response)
    drive_service.files().delete()drive_service.files().emptyTrash() 添加了
  • execute()

如果这不是您想要的结果,我深表歉意。
