I’m submitting a…

Current behavior

I got the id of the asset from content.
And I got the picture in assets but I wanna to get the asset in blob storage directly.
I found the picture stored in blob storage have different name from the id.
The name in blob storage have prefix and suffix.
How can I get the name of the asset in blob storage?

Expected behavior

api can also return the id of assets in blob storage.

In the blog storage the ID is used. If you edit an asset you get a dialog that shows this ID.

Do you mean the Identity in edit mode?

However, the id in blob storage has the prefix and suffix.
And I found that you mention the suffix is “_0” in other topic.

Yes, thats the identity. The file version is added as prefix, so “_0” for the initial upload, “_1” for a new upload / save of the same file and so on.

Hi, I think the prefix is the id of the app, but I don’t know how to get it all in one query.
I am using Squidex C# SDK.

Yes, there is an old semantic and a new semantic:

        // OLD
        private static string GetFileName(DomainId id, long fileVersion)
            return $"{id}_{fileVersion}";

        // NEW
        private static string GetFileName(DomainId appId, DomainId id, long fileVersion)
            return $"{appId}_{id}_{fileVersion}";

The asset client has this method, which can be used:

Let me take a look. Thanks.

I only found
Task<AssetDto> GetAssetAsync(string app, string id, CancellationToken cancellationToken = default);
in the SDK.
Cannot find the getFileName function.

Get file name is from the server…, I just wanted to show you the different names.

Do you mean I should create a function like this? But how can I get the appId?

If you check your chrome network tab, search for a call to /api/apps and check the response. It has a list of apps with their ids.

I found the id in the chrome response.
Is there any way to get the id from SDK?
Do you mean I have to hard code the id only?

I would just hardcode it…

Okay, I will just hardcode it. Thanks!
