Is there a matlab network package called matlab.net​.http.fiel​d.SessionS​tate?

Hi, I am using https://github.com/jebej/MatlabWebSocket to connect a sensor server ,

AI google studio give me some codes, one is :

import matlab.net.http.field.SessionState;

which is a core netwrok service, it told me. but the matlab can not find it,

so the AI let me run:

exist(fullfile(matlabroot, 'toolbox', 'matlab', 'network', '+matlab', '+net', '+http'), 'dir')

and the answer is 0, so the AI told me that some core package related network is missing.

But I reinstalled the matlab, still can not find the package.

Is AI correct or AI hallucinations?

Hello @jun,

It seems like the AI agent has provided some inaccurate information regarding the existence of "matlab.net.http.field.SessionState" class.

The command you used needs some modifications as shown below, as "matlab.net.http.field" package is a part of the MATLAB's Web Services interface :

>> exist(fullfile(matlabroot, 'toolbox', 'matlab', 'external', 'interfaces', 'webservices', 'http', '+matlab', '+net', '+http', '+field'), 'dir')

To verify the list of officially supported HTTP header field classes, you can refer to the MATLAB documentation here:

• https://www.mathworks.com/help/releases/R2023a/matlab/ref/matlab.net.http.field-package.html

This page lists all available classes in the "matlab.net.http.field" package. As you’ll see, there is no "SessionState" field included.

I hope this resolves your query.
