wfs是OGC的标准规范,主要用于提供对矢量地理数据的服务,我们以一个对摄像头图层进行操作为例了解如何通过openlayer+geoserver实现WFS操作。

首先利用postgis建表camera,参照http://postgis.refractions.net/docs/ch04.html

接着在geoserver中创建相关图层camera,数据来源为刚建立的postgis表

修改geoserver的WFS service配置,将Service Level改为Transactional,实现事物级的操作。

此时我们已经完成了服务器端的配置,接着通过openlayer来实现对WFS服务的调用。

wfs-protocol-transactions.js

//定义DeleteFeature类

var DeleteFeature = OpenLayers.Class(OpenLayers.Control, {
initialize: function(layer, options) {
OpenLayers.Control.prototype.initialize.apply(this, [options]);
this.layer = layer;
this.handler = new OpenLayers.Handler.Feature(
this, layer, {click: this.clickFeature}
);
},
clickFeature: function(feature) {
// if feature doesn't have a fid, destroy it
if(feature.fid == undefined) {
this.layer.destroyFeatures([feature]);
} else {
feature.state = OpenLayers.State.DELETE;
this.layer.events.triggerEvent("afterfeaturemodified",
{feature: feature});
feature.renderIntent = "select";
this.layer.drawFeature(feature);
}
},
setMap: function(map) {
this.handler.setMap(map);
OpenLayers.Control.prototype.setMap.apply(this, arguments);
},
CLASS_NAME: "OpenLayers.Control.DeleteFeature"
}); function init() { var mapOptions = {
resolutions: [],
projection: new OpenLayers.Projection('EPSG:900913'),
maxExtent: new OpenLayers.Bounds(1.2636720449E7,2510310.336,1.2787005936E7,2660595.8230000017),
units: "meters",
controls: []
}; map = new OpenLayers.Map('map', mapOptions ); var wms = new OpenLayers.Layer.WMS(
"szroad","http://yourgeoserver:8088/geoserver/gwc/service/wms",
{layers: 'szroad', format: 'image/png' },
{ tileSize: new OpenLayers.Size(256,256) }
); var saveStrategy = new OpenLayers.Strategy.Save(); wfs = new OpenLayers.Layer.Vector("Editable Features", {
strategies: [new OpenLayers.Strategy.BBOX(), saveStrategy],
projection: new OpenLayers.Projection("EPSG:900913"),

})
}); map.addLayers([wms, wfs]); var panel = new OpenLayers.Control.Panel(
{'displayClass': 'customEditingToolbar'}
); var navigate = new OpenLayers.Control.Navigation({
title: "Pan Map"
}); var drawCamera = new OpenLayers.Control.DrawFeature(
wfs, OpenLayers.Handler.Point,
{
title: "Draw Feature",
displayClass: "olControlDrawFeaturePoint"
}
); drawCamera.featureAdded = function(feature) {
feature.attributes ={"code":"100000001","name":"一号摄像头"};
} var editCamera = new OpenLayers.Control.ModifyFeature(wfs, {
title: "Modify Feature",
displayClass: "olControlModifyFeature"
}); var delCamera = new DeleteFeature(wfs, {title: "Delete Feature"}); var saveCamera = new OpenLayers.Control.Button({
title: "Save Changes",
trigger: function() {
if(editCamera.feature) {
editCamera.selectControl.unselectAll();
}
saveStrategy.save();
},
displayClass: "olControlSaveFeatures"
}); panel.addControls([navigate, saveCamera, delCamera, editCamera, drawCamera]);
panel.defaultControl = navigate;
map.addControl(panel);
map.zoomTo(3);
}

注意:

1.openlayer中WFS layer的featureNS为geoserver中编辑的矢量图层的workspace 的Namespace URI。

2.提交wfs服务时js存在跨域问题,所以必须保证地图web server和WFS服务器在同一域环境下。
