Connect a local Restserver

WEB TMS WEB Core
1

i can't connect to a local Restserver:


TMS WEB Runs on Port 8000, the local REST Server Runs on Port 8089:

 WebClientConnection1.URI :='http://localhost:8089/artikel?2';
 WebClientConnection1.Active:=True;

Error connecting to URI http://localhost:8089/artikel?2 | fMessage::Error connecting to URI http://localhost:8089/artikel?2 fHelpContext::0
at http://localhost:8000/TestDBWeb/TestDBWeb.js

Is the browser console giving more details on the error?

3

Access to XMLHttpRequest at 'http://localhost:8089/artikel?2' from origin 'http://localhost:8000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

So, you need to enable CORS on this local server. Because it is on a different port, it is considered from a different origin.

ok, now it works.
