我正在尝试将Google Drive API v3与Python 3配合使用,以自动上传文件,将其设置为“公开”并获取任何人都可以查看和下载的共享链接(但不能修改)。
我已经接近了,但是还不太清楚!遵守我的代码。它要求一个名为“ testing.txt”的文本文件与脚本位于同一目录:
from googleapiclient.discovery import build
from httplib2 import Http
from oauth2client import file, client, tools
from apiclient.http import MediaFileUpload
from apiclient import errors
# https://developers.google.com/drive/api/v2/about-auth#requesting_full_drive_scope_during_app_development
SCOPES = 'https://www.googleapis.com/auth/drive' # https://stackoverflow.com/a/32309750
# https://developers.google.com/drive/api/v2/reference/permissions/update
def update_permission(service, file_id, permission_id, new_role, type):
"""Update a permission's role.
Args:
service: Drive API service instance.
file_id: ID of the file to update permission for.
permission_id: ID of the permission to update.
new_role: The value 'owner', 'writer' or 'reader'.
Returns:
The updated permission if successful, None otherwise.
"""
try:
# First retrieve the permission from the API.
permission = service.permissions().get(fileId=file_id, permissionId=permission_id).execute()
permission['role'] = new_role
permission['type'] = type
return service.permissions().update(fileId=file_id, permissionId=permission_id, body=permission).execute()
except errors.HttpError as error:
print('An error occurred:', error)
return None
if __name__ == '__main__':
# credential things
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)
drive_service = build('drive', 'v3', http=creds.authorize(Http()))
# create and upload file
file_metadata = {'name': 'testing.txt'}
media = MediaFileUpload('testing.txt',
mimetype='text/txt')
file = drive_service.files().create(body=file_metadata,
media_body=media,
fields='id, webViewLink, permissions').execute()
# get information needed to update permissions
file_id = file['id']
permission_id = file['permissions'][0]['id']
print(file_id)
print(permission_id)
# update permissions? It doesn't work!
update_permission(drive_service, file_id, permission_id, 'reader', 'anyone') # https://stackoverflow.com/a/11669565
print(file.get('webViewLink'))
运行此代码时,收到以下消息:
1quyzYHc0uCQIEt88gqd4h_jWtlBaoHHH
01486072639937946874
An error occurred: <HttpError 403 when requesting https://www.googleapis.com/drive/v3/files/1quyzYHc0uCQIEt88gqd4h_jWtlBaoHHH/permissions/01486072639937946874?alt=json returned "The resource body includes fields which are not directly writable.">
https://drive.google.com/file/d/1quyzYHc0uCQIEt88gqd4h_jWtlBaoHHH/view?usp=drivesdk
当我将最终链接复制并粘贴到另一个浏览器中时,它不可用,因此很明显,它未能成功更改文件权限。但是我不明白为什么它失败了。它提到了The resource body includes fields which are not directly writable
,但我不知道这意味着什么。
有人可以帮助我了解我做错了什么以及需要解决的问题才能解决?谢谢。

选择的答案不够精确(与类型值和角色无关),因此我不得不多读一些文档,这是一个有效的示例,您只需要提供file_id:
def set_permission(service, file_id):
print(file_id)
try:
permission = {'type': 'anyone',
'value': 'anyone',
'role': 'reader'}
return service.permissions().create(fileId=file_id,body=permission).execute()
except errors.HttpError as error:
return print('Error while setting permission:', error)

此修改如何?我认为您已经可以上传文件了。因此,我想对update_permission()
的功能进行修改。
service.permissions().create()
。请如下修改update_permission()
。
try:
# First retrieve the permission from the API.
permission = service.permissions().get(fileId=file_id, permissionId=permission_id).execute()
permission['role'] = new_role
permission['type'] = type
return service.permissions().update(fileId=file_id, permissionId=permission_id, body=permission).execute()
except errors.HttpError as error:
print('An error occurred:', error)
return None
至:
try:
permission = {
"role": new_role,
"type": types,
}
return service.permissions().create(fileId=file_id, body=permission).execute()
except errors.HttpError as error:
print('An error occurred:', error)
return None
如果我误解了你的问题,对不起。

错别字:请注意,在初始代码中,它在 update_permission 的函数标头中说“ type”,但是在更正的代码段中,回复使用“ types”。
