ArcGIS Oauth Error Handle

Question

Hi,

I am making an app which allows the user to search their own contents from ArcGIS Online, and share with others.

But if the user includes the contents that are not open to the public, a sign-in window will pop up.

Is there an elegant way to handle this error?

Thanks.

That is exactly what I did!

But the problem is that if the first user(the owner of the data source) change the sharing status to be organizational or private later, the wrong data source will trap the second user...

Robert,

I am not using Portal to access the items, instead, I simply use a MySQL to store the metadata, e.g. itemId, dataUrl. These layers are all from ArcGIS Online.

My code constructed in this way:

* Connect to DB to retrieve all the layers' metadata.
* Based on the metadata, make requests and use related functions to create layers.

The problem raised in the second step. Because the privilege problems could be in any layers, and I cannot find a way to know whether there is an error. And the error will block the remaining codes, which is fatal.

How is the first user "passing the items" to the second user? My initial reaction is that the right way to do this is to pass a query around. So, user A picks out 3 items from their contents and you build a query that searches ArcGIS Online, something like: id: OR id: OR id: Then user B, who is viewing the items, executes the query that user A built. They will only get a response for items that they have access to.
