I’m currently facing an issue while attempting to retrieve the file bytes of a file stored on Google Drive. I have followed the documentation and successfully created the necessary credentials and granted the required permissions. However, I am encountering difficulties in obtaining the bytes of the file in order to read its content.
To retrieve the file content from Google Drive, you can use the Google Drive API. Here’s a general overview of the steps involved:
Here’s an example using the Google Drive API in Python:
import io
import os
from google.oauth2 import service_account
from googleapiclient.discovery import build
# Set up credentials
credentials = service_account.Credentials.from_service_account_file(‘path/to/credentials.json’)
scopes = [‘https://www.googleapis.com/auth/drive.readonly’]
credentials = credentials.with_scopes(scopes)
# Build the Google Drive API client
drive_service = build(‘drive’, ‘v3’, credentials=credentials)
# File ID of the desired file on Google Drive
file_id = ‘your_file_id’
# Make an API request to get the file metadata
file_metadata = drive_service.files().get(fileId=file_id).execute()
# Get the download URL of the file
download_url = file_metadata[‘webContentLink’]
# Use the download URL to download the file content
response = drive_service.files().get_media(fileId=file_id).execute()
# Read the file content
content = io.BytesIO()
content.write(response)
# Do whatever you need with the file content
print(content.getvalue())
Make sure to replace
'path/to/credentials.json'
with the actual path to your service account credentials JSON file, and'your_file_id'
with the ID of the file you want to retrieve.Remember to handle exceptions, handle authorization token refresh, and manage file access permissions based on your specific requirements.
