Re: CORS configuration in HTTP Service

[Frank Langel]

Hi, 

Created filter service, which works fine, but isn’t there an easier 
(configuration) option ? 

Thanks 
Frank



import java.io.IOException;



import javax.servlet.Filter;

import javax.servlet.FilterChain;

import javax.servlet.FilterConfig;

import javax.servlet.ServletException;

import javax.servlet.ServletRequest;

import javax.servlet.ServletResponse;

import javax.servlet.http.HttpServletResponse;



import org.osgi.service.component.annotations.Component;



@Component(immediate=true,property={"pattern=/.*"})

public class CustomFilter implements Filter {



@Override

public void destroy() {

// TODO Auto-generated method stub

}



@Override

public void doFilter(ServletRequest arg0, ServletResponse arg1, FilterChain 
chain)

throws IOException, ServletException {



System.out.println("Filtering");



    HttpServletResponse res = (HttpServletResponse) arg1;



    res.addHeader("Access-Control-Allow-Origin","*");

    res.addHeader("Access-Control-Allow-Methods","GET,POST");

    res.addHeader("Access-Control-Allow-Headers","Origin, X-Requested-With, 
Content-Type, Accept");



    chain.doFilter(arg0,arg1);

}



@Override

public void init(FilterConfig arg0) throws ServletException {

}



}

Subject:  CORS configuration in HTTP Service

Hi team,

I like to configure CORS (Cross Origin Requests) by always returning the 
following http parameter

Access-Control-Allow-Origin: *

in the response. One option is to write a http filter server that adds the 
parameter, but this is quite a bit of work for adding a simple parameter. 
Jetty supports that kind of configuration in web.xml but I think web.xml is not 
working under Felix http.

Any easy way to add a http parameter to each response of each http server?
Thanks
Frank
