Attachment URL with Token

DavidPuckett

I have used the example in the attachments sample to 'manually' construct a url for an attachment

For unsecured services\attachments, I can set an Image source to this url successfully.
E.g.

const attachmentUrl = featureLayerUrl + "/" + oid + "/attachments/" + attachment.attachmentId

However, for secured services, constructing the url in this way and then appending the Credential token does not work.
E.g.

const attachmentUrl = featureLayerUrl + "/" + oid + "/attachments/" + attachment.attachmentId + "?token=" + app.portal.credential.token

The image status reports an Image.Error

onStatusChanged: if (thumbnail.status === Image.Error) workRecordThumbnail.source = "../assets/image-error.png"

The portal credential works to access the services (feature layers) but it seems I cannot simply append the credential token to the attachment url to view the attachment.

I am creating the Credential like this:

Credential {
  id: portalCredential
  oAuthClientInfo: OAuthClientInfo {
    oAuthMode: Enums.OAuthModeUser
    clientId: app.clientId
  }
}

Any help?

Have you tried including the f query parameter to your attachmentURL?

const attachmentUrl = featureLayerUrl + "/" + oid + "/attachments/" + attachment.attachmentId + "?f=json&token=" + app.portal.credential.token
