Consuming PCo WebSocket using SAPUI5

[Former Member]

Hi there,

I've read a lot about PCo and its ability to provide WebSockets. There is a document about configuring PIC consuming the PCo data here:

The SSCE is able to use the WebSockets provided by PCo. However, how do I consume the WebSockets via a SAPUI5 application I wrote myself? Is there a help document for this issue?

Regards

Hi Tobias,

you could simply add an update call to the model you use for the MVC:

mockWs.onmessage = function(event) {
    // retrieve the message and put it into a JSONModel
    var jsonData = JSON.parse(event.data);
   oModel.setProperty("/some", jQuery.merge([jsonData], oModel.getProperty("/some")));
   oModel.refresh(/* force */ true);
}; 

See this gist for a working example: Example Websocket usage with Sapui5

Am I missing something? I guess you are looking for something a bit more built-in.

Thanks Martin, this is a very good example, but using standard JavaScript WebSocket. I thought about using a SAPUI5 class like SapPcpWebSocket, see here:

SAPUI5 SDK - Demo Kit

Anyway, using standard WebSocket doesn't seem to be that complex. Thanks for your solution.
