i'm using openlayers-3.6.0 in web application. have wfs layer follow:

var url="http://localhost:8080/geoserver/wfs?&" +        "service=wfs&version=1.1.0&request=getfeature&typenames=usa:states"; var format = new ol.format.wfs({}); var source = new ol.source.vector({     url: 'proxy.cgi?url='+ encodeuricomponent(url),     format: format }); layer wfs = new ol.layer.vector({     title: 'states',     source: source });

i edit point layer follow:

draw = new ol.interaction.draw({     source: source,     type: 'point' });

now want save layer in server side. in openlayers-2 defined savestrategy , call save method of it. shown follows:

var savestrategy = new openlayers.strategy.save();  /* * change layer's features */  savestratefy.save();

how can in openlayers-3.6.0?
