Pre-signed URL saved on model expired about attachment-lite HOT 4 CLOSED

Yup. Actually, we shouldn't be saving URL in the database at all and always compute it at runtime. Only the name and other meta data should be saved

from attachment-lite.

Can you please share some code, with the actual output you get and the expected output?

Hi, Thank you for the reply.

The visibility of my s3 config is set to private. So when I create a new model with preComputeUrl option, the attachment file url will be signed according to documentation.

It stored like the following in database.

{"url": "https://s3.ap.amazonaws.com/xxxx/cl2fx7fpe0003jj796udk1k6w.png?signed-params****", "name": "cl2fx7fpe0003jj796udk1k6w.png", "size": 834039, "extname": "png", "mimeType": "image/png"}

I can access the resource with the above pre-signed url. The problem is when the pre-signed url expired, attachment-lite is still returning the same pre-signed url and the resource is no longer available..

from attachment-lite.

I think the issue is from here:

/**
     * Self compute the URL if "preComputeUrl" is set to true
     */
    const fileVisibility = await disk.getVisibility(this.name)
    if (fileVisibility === 'private') {
      this.url = await disk.getSignedUrl(this.name)
    } else {
      this.url = await disk.getUrl(this.name)
    }

and

 /**
   * Returns the signed URL for the file. Same as "Drive.getSignedUrl()"
   */
  public getSignedUrl(options?: ContentHeaders & { expiresIn?: string | number }) {
    return this.getDisk().getSignedUrl(this.name, options)
  }

We might need to re-generate the signed URL when when the model is fetched.
