Note that there is the "GetStyles" request (it's part of the SLD spec) - this
returns the Style used for the layer as XML.
There are various convertors out there to convert XML to JSON - if you plugged
one of them in as a piece of middleware between the client which needs JSON and
GeoServer which is returning XML, you can probably get the desired outcome.
You can then parse the JSON to determine what the legend should be; easy for
simple things (i.e. a polygon with a fill), but probably not desirable for more
complex styles.
Cheers,
Jonathan

Form ArcMap service - we get JSON for Legend similar to this
https://pxxxx.com/arcgis/rest/services/aaa/aaa/MapServer/Legend?f=pjson&token=ddddd.&callback=angular.callbacks._0
angular.callbacks._0({ "layers": [ { "layerId": 1, "layerName": "abc",
"layerType": "Feature Layer", "minScale": 0, "maxScale": 0, "legend": [ {
"label": "", "url": "76d5be60e5691543860aa46358f5dcf8", "imageData":

"contentType": "image/png", "height": 20, "width": 20 } ] },
Geoserver has the option getlegendgraphics for WMS- which is returning image. I
will need something similar as above. I noticed this proposed change:
https://github.com/geoserver/geoserver/wiki/GSIP-81---GetLegendGraphic-as-text-(JSON)
Is it part of any release? I am beginner in geoserver and have installed 2.8.2
(stable release) recently. Please advise.
Thanks
