Tencent Cloud COS
A storage engine based on Tencent Cloud COS. You need to prepare the relevant account and permissions before use.
This engine does not support private access. After a file is uploaded, NocoBase generates a directly accessible URL, and anyone who has that URL can access the file.
Even if the COS bucket itself is private, the built-in Tencent COS engine does not generate temporary signed URLs for file access. If you need private access, use S3 Pro. If historical files already exist, see Migrate to S3 Pro.
