• A presigned URL (https://bucket.s3.region.amazonaws.com/profile-photos/...?X-Amz-...)
• An object key (profile-photos/user-id/photo.jpg)

public static string? ExtractObjectKey(string? storedValue)

Parameters

storedValue string

The stored value from the database

Returns

string

The extracted object key, or null if the value is not a valid S3 reference

Parameters

url string

The URL to check

Returns

bool

True if the URL is an external URL (not S3), false otherwise
