我在geoserver中发布了一个shapefile“ind_adm2”作为Postgis(postgres数据库),它可以使用下面给出的OpenLayers代码作为网页访问。现在我需要在网页上编辑shapefile并在Postgres数据库中保存已编辑(更新)的内容。谁能帮忙!!
我尝试使用geoserver的wfs URL但无法选择该功能。
<html>
<head>
<script src="http://openlayers.org/api/OpenLayers.js"></script>
</head>
<body>
<div style="width:100%; height:100%" id="map"></div>
<script defer="defer" type="text/javascript">
var map = new OpenLayers.Map('map');
basemap = new OpenLayers.Layer.WMS( "Layer Name1",
"http://vmap0.tiles.osgeo.org/wms/vmap0", {layers: 'basic'} );
utility = new OpenLayers.Layer.WMS( "Layer Name2",
"http://localhost:8080/geoserver/iirs/ows?", {layers: 'iirs:ind_adm2',
transparent:"true"}, {isBaseLayer:false} );
map.addLayers([basemap,utility]);
map.zoomToMaxExtent();
</script>
</body>
</html>
它应该选择任何多边形然后在那里编辑并更新postgres数据库中的编辑。
因为您需要的内容将比现有代码复杂得多,您应该将其更新到最新版本的OpenLayers(目前为5.3.0)并使用它进行开发。使用完全构建的https://openlayers.org/en/latest/doc/quickstart.html更容易,这与使用版本3和4非常相似,因此您将能够重用这些版本中的示例。有关编辑WFS的帮助,请参阅链接教程和一些示例Javascript editing WFS from GeoServer using OpenLayers的一个问题
