Play Framework CORS Headers

Question

I\'m trying to set CORS Headers for my play framework app. Specifically I\'m getting this error

cannot load http://127.0.0.1:9000/. No \'Access-Control-Allow         


        

Answer 1

for me it worked after one day (maybe cash or other things)

application.conf:

play.http.filters = "filters.Filters"

play.filters.cors {
  # allow all paths
  pathPrefixes = ["/"]
 # allow all origins (You can specify if you want)
 allowedOrigins = null
 allowedHttpMethods = ["GET", "POST"]
 # allow all headers
 allowedHttpHeaders = null
}  

build.sbt :

val appDependencies = Seq(
filters,
....
)

in package filters.Filter :

package filters;

import javax.inject.Inject;
import play.mvc.EssentialFilter;
import play.filters.cors.CORSFilter;
import play.http.DefaultHttpFilters;

public class Filters extends DefaultHttpFilters {

CORSFilter corsFilter;

@Inject
public Filters(CORSFilter corsFilter) {
    super(corsFilter);
    this.corsFilter = corsFilter;
   }

public EssentialFilter[] filters() {
    return new EssentialFilter[] { corsFilter.asJava() };
}
}

and in my ajax call:

$.ajax({
    method:'GET',
    url: xxxxxxxx',
    dataType: 'json',
    headers: {'url': yyyyy,
    'Access-Control-Allow-Origin': '*',
    'Access-Control-Allow-Methods': 'GET, POST, PUT',
    'Access-Control-Allow-Headers': 'Content-Type'
    },
    success: function(data) { 
....}); 

i have no more error, in prod and in local environment !! thank you all
