Version 12.3 : Net core API GetImageFileInfo response error

Post by jwalit.katira » Tue Dec 05, 2023 12:51 PM

Hi Team,

I have updated Net Core API to Version 12.3, MyVintasoftImageCollectionApi/GetImageFileInfo is responding as error as below, I have not override this method

{
    "files": null,
    "success": false,
    "blocked": false,
    "errorMessage": "Data storage item key is not correct. (Parameter 'key')\r\n",
    "requestId": null
}

Above is called when i give file to image viewer

imageViewer.get_Images().openFile("C://Jwalit//Sample Files//24521447.tif");

Above is working properly in 12.2.11

Let me know if any changes need to be done for version 12.3

Thanks
Jwalit Katira

Hi Jwalit,

In version 12.3 the "Data storage item key is not correct" error occurs if file identifier is a rooted path.

Why do you use rooted path as a file identifier?

Hello Jwalit,

For solving the problem you need to do the following steps:

In each Vintasoft API controller override the CreateSessionDataStorage method:

protected override IDataStorage CreateSessionDataStorage(string sessionId)
{
    if (sessionId == null)
    {
        if (IsEmptySessionSupported)
            sessionId = "";
        else
            throw new ArgumentNullException("sessionId");
    }

    string path = Path.Combine("C://Jwalit//Sample Files", sessionId);

    if (!Directory.Exists(path))
        Directory.CreateDirectory(path);

    return new StreamDataStorage(path);
}

Use file names (for example "24521447.tif") as file identifiers.

Please try to update your code and let me know if you will have any question or problem.

Best regards, Alexander

Hi Jwalit,

Data storage concatenates the storage folder path and file name if file path is necessary.

In your case:
1. The storage folder path is "C:/Jwalit/Sample Files/{sessionId}/"
2. File name is "24521447.tif"

Please make sure that your computer has file with path "C:/Jwalit/Sample Files/{sessionId}/24521447.tif".

Best regards, Alexander
