我对在Google驱动器中工作很陌生,我很清楚我不能问stackoverflow以下情况的完整示例,但是,如果您可以将我引导到类似的地方,那将非常有帮助。我很困,无法前进。
我已经在Google云端硬盘中上传了7-8 GB的pdf文件,其中包括pdf,docx,ppt等。我的担心是列出所有包含用户查询的术语的文件。例如,如果我要搜索“使用google drive api的计算机视觉”,则结果应包含包含“计算机视觉”一词的文件列表。
以上情况是可能的,当我在Google云端硬盘搜索框中输入内容时,以下是屏幕截图。
[当我输入机器学习信息时,会得到文件列表。如何以编程方式检索相同的结果。我已经阅读了Google Drive API的文档,并遇到了句法“全文包含术语”,但后来我不知道如何使用它。
正如您正确说的那样,执行此操作的一种简单方法是使用请求的q
参数以及fullText contains X
运算符。在下面,您可以从使用此功能的参考中看到Python Quickstart的改编:
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=1000, fields="nextPageToken, files(id, name)", q="fullText contains 'computer vision'").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()
在调用q
方法时注意service.files().list()
参数。
