I’m working on a PHP script that needs to upload files from my server to Google Drive. I’ve been following the Google Drive API documentation but I keep running into authentication issues.
I get this error message: fopen(compress.zlib://https://www.googleapis.com/upload/drive/v3/files?uploadType=multipart) failed to open stream
I think the problem is with OAuth authentication but I’m not sure how to fix it. Has anyone successfully implemented file uploads to Google Drive with PHP? What am I missing in my setup?
Your main problem is the authentication flow. You’re not handling the OAuth token exchange properly before hitting the API. Ensure you’ve set up your client credentials correctly, redirect users to Google’s auth URL, and then swap the authorization code for an access token. It’s important to store the refresh token for automated uploads. Additionally, your file upload parameters are inaccurate. Use ‘uploadType’ => ‘media’ for simple uploads or consider resumable uploads for larger files. The compress.zlib error indicates the client isn’t authenticated; make sure to obtain a valid access token first. If you’re performing server-to-server interactions, consider using service account authentication.
yeah, fix the oauth token first! also, php uses . for concatenation, not +. that’s probably what’s breaking it. check your token retrieval process too!
