Re: [aerogear-dev] AG-Controller and Aerogear.js CORS interaction

Hey Luke, >I'm guessing that it has something to do with the "Consume" functionality that is not yet there? Yeah, you are right. Sorry about this, but we had to push this to CR1 where we will have support for specifying consumers and will have a JSON consumer out of the box. /Dan On 18 December 2012 15:44, Lucas Holmquist <lholmqui(a)redhat.com&gt; wrote: I'm not sure if this is possible yet, but i'm trying to do a POST to the aerogear-controller-demo from our js libs $( function() { var pipeline = AeroGear.Pipeline( { name: "controllerPipe", settings: { baseURL: "http://localhost:8080/aerogear-controller-demo", endpoint: "/cars" } } ); var controllerPipe = pipeline.pipes.controllerPipe; controllerPipe.save( { color: "black", brand: "bmw" }, { success: function( data ) { console.log( data ); }, error: function( error ) { console.log( error ); } }); }); Which should hit this route, it's modified to return the object as JSON, like i needed for the GET request route() .from("/cars") .on(RequestMethod.POST) .produces(MediaType.JSON.toString()) .to(Home.class).save(param(Car.class)); This is the request info from chrome dev tools Request URL:http://localhost:8080/aerogear-controller-demo/cars Request Method:POST Status Code:200 OK Request Headersview source Accept:application/json, text/javascript, */*; q=0.01 Accept-Charset:ISO-8859-1,utf-8;q=0.7,*;q=0.3 Accept-Encoding:gzip,deflate,sdch Accept-Language:en-US,en;q=0.8 Cache-Control:no-cache Connection:keep-alive Content-Length:31 Content-Type:application/json Host:localhost:8080 Origin:http://localhost:3501 Pragma:no-cache Referer:http://localhost:3501/ User-Agent:Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_2) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.97 Safari/537.11 Request Payload {"color":"black","brand":"bmw"} Everything returns ok, but it returns null. I noticed that in aerogear-controller, in DefaultRouteProcessor.java in the extractParameters method Map<String, String[]> parameterMap = request.getParameterMap(); which would be blank since the values are in the request body I'm guessing that it has something to do with the "Consume" functionality that is not yet there? Just wanted to see if i was doing something wrong -Luke On Dec 12, 2012, at 10:49 AM, Lucas Holmquist <lholmqui(a)redhat.com&gt; wrote: > > > > On Dec 12, 2012, at 10:37 AM, Lucas Holmquist <lholmqui(a)redhat.com&gt; wrote: > >> >> On Dec 12, 2012, at 10:13 AM, Daniel Bevenius <daniel.bevenius(a)gmail.com&gt; wrote: >> >>> I think the issue here it that the request is being denied by the server as the media type specified in the Accept Header is not supported by the route.
