Hello, I’m using digital ocean to allow users to upload videos using signed urls. However i wanna make sure the the file is the file size it request to upload, and current after hours of searching for an answer i cannot find one.
So my question is, how can i prevent users to steal the signed url and upload a massive file?
PS: I’m using ‘@aws-sdk/s3-request-presigner’ with the function getSignedUrl() as the example from DO says

Heya,
If you’re looking to limit the upload size of files using pre-signed URLs, you can achieve this by using content-length-range in the conditions of your pre-signed URL policy. Set a minimum and maximum file size range to restrict uploading of larger files.
Here’s an example:
- "conditions": [
- ["content-length-range", _minSize_, _maxSize_]
- ]
By replacing the minSize and maxSize values with your desired file size limits, you can prevent users from uploading files outside that size range.
For more details on how to control the size of the uploaded files, please refer to DigitalOcean Spaces Documentation: Handling File Uploads.
Hope that this helps!
