Web AppBuilder CORS request failed

Question asked by qiqbal on Aug 12, 2015

I have created a widget which reads the data from database table using Ajax dojo.xhrGet() function to retrieve data in JSON format from  a php script.

In Internet Explorer, once I run the widget, it gives me an warning dialog "The page is accessing information that is not under its control. This poses a security risk. Do you want to continue?" when I click Yes, the widget works fine, if no is clicked it fails.

In other browsers, I get the error, with the below message in console

 

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://..../GlobalSearch.php?token=5440%20Fulton%20Industrial. (Reason: CORS header 'Access-Control-Allow-Origin' missing).

 

I want to know how can I use http PROXY on node.js.

I am testing the widget on

http://[computerName]:3344/webappviewer/?config=sample-configs/config-demo.json

 

Any help will be appreciated.

Thanks
