How to get file information in google drive using google drive url in google drive api - google-drive-api

Question

Does anyone know if this is possible?
i think i can do it by extracting id from url.
then execute code like below.
service = build('drive', 'v3', credentials=creds)
# Call the Drive v3 API
results = service.files().list(
pageSize=10, fields="nextPageToken, files(id, name,parents,owners)",q="'drive id' in parents"
).execute()

however parsing url might fail sometime.
so i would like to know how to get file information in drive by specify url.

To ensure the parsing URL will not fail, you can use the findall function in regex in extracting the folder ID from the folder URL. Since the structure of the folder URL is static except for the id part, this pattern will guarantee the extraction of folder Id
Regex Pattern
"/folders\/(.*)\?resourcekey"
Please see sample code below for getting the files in a specific folder in my google drive
Code:
from googleapiclient.discovery import build
from google.colab import auth
from google.auth import default
import re
auth.authenticate_user()
creds, _ = default()
# Build the service
service = build('drive', 'v3', credentials=creds)
# Google drive folder's URL
folder_url = 'https://drive.google.com/corp/drive/folders/1bBWIXbinmb-DQ1z_fspsvxlw3vt8v6Wa?resourcekey=0-3Q_nXWmlLp_eG79NzcRe5w'
# Get the folder's ID from the URL using regex
folder_id = re.findall("/folders\/(.*)\?resourcekey", folder_url)
#query
query = f"'{folder_id[0]}' in parents"
# List the files in the folder
results = service.files().list(pageSize=10, fields="nextPageToken, files(id, name,parents,owners)",q=query).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']))
