[Geoserver-users] GeoServer get GeoJSON issue

GeoServer GeoServer User

Greetings,

I am using GeoServer version 2.2.5, and what I try to do is making a AJAX call to get the json string from the output GeoJSON url, for example:

http://localhost:8080/geoserver/sf/ows?service=WFS&version=1.0.0&request=GetFeature&typeName=sf:archsites&maxFeatures=50&outputFormat=json

the javascript I used is like this:

var processJSON = function (data) {
console.log(data);
};
function init() {
//geojson url
var url = “http://localhost:8080/geoserver/sf/ows?service=WFS&version=1.0.0&request=GetFeature&typeName=sf:archsites&maxFeatures=50&outputFormat=json&&format_options=callback:processJSON”;

//execuate ajax request to get data
$.ajax({
url: url,
dataType: ‘jsonp’,
jsonp: ‘processJSON’
});

}

I am pretty sure that this method works, because I can get the json object from the url which is from GeoServer version 2.2.4. But it just doesn’t work for GeoServer 2.2.5 and later. I read somewhere that says “JSONP support has been disabled by default since it is perceived as a security issue.” But I have no idea how to make it work.

Can anyone give me some suggestion on this?

Thank you very much

By reading the docs:
