openlayer 加载wfs 2种方式_openlayer加载wfs数据

1.geojson

	var geo = new OpenLayers.Layer.Vector("EarthQuake", {
	    strategies: [new OpenLayers.Strategy.Fixed()],
	    protocol: new OpenLayers.Protocol.HTTP({
	        url: 'http://172.31.170.98:8088/geoserver/weidong/ows?service=WFS&version=1.0.0&request=GetFeature&typeName=weidong:weidong-vectorlayer&maxFeatures=50&outputFormat=application/json',
	        format: new OpenLayers.Format.GeoJSON({ignoreExtraDims: true})
	    })
	});

2.KML

	buildsLayer = new OpenLayers.Layer.Vector('矢量图层', {  
		projection: new OpenLayers.Projection('EPSG:4326'),  
		protocol: new OpenLayers.Protocol.HTTP({  
			url: 'http://172.31.170.98:8088/geoserver/weidong/ows?service=WFS&version=1.0.0&request=GetFeature&typeName=weidong:weidong-vectorlayer&maxFeatures=50',  
			format: new OpenLayers.Format.GML({  
					extractAttributes:true  
				})  
			}),  
			strategies: [new OpenLayers.Strategy.BBOX()]  
	});
	var buildsLayer_style = new OpenLayers.Style({  
		'fillOpacity': 0,
		'fillColor':"yellow",
		'strokeColor': 'yellow',  
		'strokeWidth': 0,  
		'pointRadius': 8  
	});  
	var buildsLayer_style_map = new OpenLayers.StyleMap({  
		'default': buildsLayer_style
	});  
	buildsLayer.styleMap = buildsLayer_style_map;  

url可以在geoserver 中预览视图中得到
