[英]How to fetch name of all files in google drive using google drive api?
我正在嘗試獲取 google 驅動器中所有文件的名稱,但問題是我只能獲取特定數量的文件,如何刪除此限制並獲取所有文件,這是 google 在其網站上提供的代碼
我正在使用谷歌驅動器 API v3
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()
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()
在這段代碼中有一個變量 pageSize ,它的值是 10,如果我增加它的值,這樣我就可以獲取更多文件,但我想獲取所有文件,所以我該怎么做。
Files.list有一個名為 pagesize 的可選參數
pageSize integer 每頁返回的最大文件數。 即使在到達文件列表末尾之前,部分或空的結果頁面也是可能的。 可接受的值為 1 到 1000,包括 1 到 1000。 (默認值:100)
您已將您的 pageSize=10 設置為 1000,然后使用 nextPageToken 選擇下一組行(如果有更多行)。
我不是 python 開發人員,以下代碼是猜測。
page_token = saved_start_page_token;
while page_token is not None:
response = service.changes().list(pageToken=page_token,
pageSize=1000, fields="nextPageToken, files(id, name)").execute()
page_token = response.get('nextPageToken')
