要达到的效果显示geoserver中发布的wms图层,数据使用geoserver自带的示例数据。安装后geoserver后就有的数据

官网示例链接:https://openlayers.org/en/latest/examples/wms-custom-tilegrid-512×256.html

1、创建源TileWMS

var wmsSource = new ol.source.TileWMS({
url: ‘http://localhost:8080/geoserver/tiger/wms’,//端口号要改成自己的
params: {
‘FORMAT’: format,
‘VERSION’: ‘1.1.1’,
tiled: true,
“LAYERS”: ‘tiger:poi’,//tiger–图层的名称空间,poi–图层名称
“exceptions”: ‘application/vnd.ogc.se_inimage’,
},
serverType: ‘geoserver’,//服务类型geoerver
crossOrigin: ‘anonymous’,
});
上面使用的图层来自geoserver

 

2、创建tile

var wmsLayer = new ol.layer.Tile({
source: wmsSource,
});
3、加载到map中

map.addLayer(wmsLayer);
效果如下
