I has been issue when I call ajax from sencha to grails.
XMLHttpRequest cannot load http://localhost:8080/ExtLogin/userInfo/index/login. Origin http://localhost:9090 is not allowed by Access-Control-Allow-Origin.
Code below:
Sencha: Sencha application deploying on “http://localhost:9090/sencha/demo/Login/” using Tomcat
Grails application using Tomcat at “http://localhost:8080/ExtLogin/userInfo/index/login”. Login function at server side render JSON is below:
def login(){
def response = ['success':'true']
response.addHeader("Access-Control-Allow-Origin", "*")
response.addHeader("Cache-Control", "no-cache")
render response as JSON
}
If request from browser, I received:
