Js Webapps, cppagent and CORS

[robot-ranger]

Hi all,

Has anyone worked with cppagent in the context of a js web app? Someone has to have made a web app for mtconnect?

How can we work with CORS? What is the default CORS policy in cppagent? Is it configurable?

The demo is a web app example that animates a digital twin. CORS policies are configurable by adding custom HTTP headers. I’ll check there docs. (Sent from mobile)On Oct 11, 2023, at 01:21, robot-ranger ***@***.***> wrote: Hi all, Has anyone worked with cppagent in the context of a js web app?

yea, my developer figured out the Http headers by reverse engineering the parsing code. we couldnt find it documented anywhere.

if anyone else stumbles on this in the future, we added the following to agent.cfg to allow all cross-origin:

HttpHeaders {
    Access-Control-Allow-Origin = *
    Access-Control-Allow-Methods = GET
    Access-Control-Allow-Headers = Content-Type
}

I believe you could replace the * with a list of origins to specify whitelisted cross-origins

Thanks, I’ll add this to the documentation. - WOn Oct 12, 2023, at 17:43, robot-ranger ***@***.***> wrote: yea, my developer figured out the Http headers by reverse engineering the parsing code. we couldnt find it documented anywhere. if anyone else stumbles on this in the future, we added the following to agent.cfg to allow all cross-origin: HttpHeaders { Access-Control-Allow-Origin = * Access-Control-Allow-Methods = GET Access-Control-Allow-Headers = Content-Type } I believe you could replace the * with a list of origins to specify whitelisted cross-origins —Reply to this email directly, view it on GitHub, or unsubscribe.You are receiving this because you commented.Message ID: ***@***.***>
