当然可以,下面是一个简单的示例代码:
```vue
<template>
<div id="map"></div>
</template>
<script>
import 'ol/ol.css';
import Map from 'ol/Map';
import View from 'ol/View';
import TileLayer from 'ol/layer/Tile';
import WMTS from 'ol/source/WMTS';
import WMTSTileGrid from 'ol/tilegrid/WMTS';
import {get as getProjection} from 'ol/proj';
import {getWidth, getTopLeft} from 'ol/extent';
import {getCenter} from 'ol/extent';
const layer = new TileLayer({
source: new WMTS({
url: 'https://my.wms.service.url.com/wms',
layer: 'mywmslayer',
matrixSet: 'EPSG:4326',
format: 'image/png',
projection: getProjection('EPSG:4326'),
tileGrid: new WMTSTileGrid({
origin: getTopLeft(getProjection('EPSG:4326').getExtent()),
resolutions: [
0.7031250000000002,
0.3515625000000001,
0.17578125000000006,
0.08789062500000003,
0.043945312500000014,
0.021972656250000007,
0.010986328125000003,
0.005493164062500001,
0.0027465820312500004,
0.0013732910156250002,
0.0006866455078125001,
0.00034332275390625006,
0.00017166137695312503,
0.00008583068847656251,
0.000042915344238281406,
0.000021457672119140703
],
matrixIds: [
'0',
'1',
'2',
'3',
'4',
'5',
'6',
'7',
'8',
'9',
'10',
'11',
'12',
'13',
'14',
'15'
]
}),
style: 'default'
})
});
export default {
name: 'MyMap',
data() {
return {
map: null,
}
},
mounted() {
this.map = new Map({
target: 'map',
layers: [layer],
view: new View({
center: getCenter(getProjection('EPSG:4326').getExtent()),
zoom: 2
})
});
}
};
</script>
```
这个示例代码中,我们使用了 `ol` 库中的 `Map`、`View`、`TileLayer`、`WMTS`、`WMTSTileGrid`、`getProjection`、`getWidth`、`getTopLeft` 和 `getCenter` 等类或函数,用于加载 `WMS` 服务。其中,`WMS` 服务的地址是 `https://my.wms.service.url.com/wms`,图层名称是 `mywmslayer`,矩阵集是 `EPSG:4326`,输出格式是 `image/png`,投影是 `EPSG:4326`,切片网格是通过 `WMTSTileGrid` 类生成的,地图样式为默认值。我们还创建了一个名为 `MyMap` 的 Vue 组件,用于在 `mounted` 钩子函数中创建地图。在地图创建完成后,我们可以将地图添加到页面中,如:
```html
<template>
<div>
<MyMap />
</div>
</template>
<script>
import MyMap from './MyMap.vue';
export default {
name: 'App',
components: {
MyMap
}
};
</script>
```
希望这个示例代码能够对你有所帮助!
