# WMS 底图

[Live example](https://l7.antv.antgroup.com/en/examples/tile/basemap/wms/)

[Resource index](/llms.txt)

Provide a DOM element with `id="container"`. The original example source follows.

## Source

```ts
// @ts-ignore
import { RasterLayer, Scene } from '@antv/l7';
// @ts-ignore
import { Map } from '@antv/l7-maps';

const scene = new Scene({
  id: 'map',

  map: new Map({
    center: [114.061677, 22.54899],
    zoom: 11,
  }),
});
const url1 =
  'https://tiles{1-3}.geovisearth.com/base/v1/img/{z}/{x}/{y}?format=webp&tmsIds=w&token=b2a0cfc132cd60b61391b9dd63c15711eadb9b38a9943e3f98160d5710aef788';
const url2 =
  'https://tiles{1-3}.geovisearth.com/base/v1/cia/{z}/{x}/{y}?format=png&tmsIds=w&token=b2a0cfc132cd60b61391b9dd63c15711eadb9b38a9943e3f98160d5710aef788';
const layer1 = new RasterLayer({
  zIndex: 1,
}).source(url1, {
  parser: {
    type: 'rasterTile',
    tileSize: 256,
  },
});

const layer2 = new RasterLayer({
  zIndex: 1,
}).source(url2, {
  parser: {
    type: 'rasterTile',
    tileSize: 256,
  },
});
// WMS 底图 BBOX获取数据
const url =
  'https://pnr.sz.gov.cn/d-suplicmap/dynamap_1/rest/services/LAND_CERTAIN/MapServer/export?F=image&FORMAT=PNG32&TRANSPARENT=true&layers=show:1&SIZE=256,256&BBOX={bbox}&BBOXSR=4326&IMAGESR=3857&DPI=90';

const layer = new RasterLayer({
  zIndex: 3,
}).source(url, {
  parser: {
    type: 'rasterTile',
    tileSize: 256,
    zoomOffset: 0,
  },
});

scene.on('loaded', () => {
  scene.addLayer(layer1);
  scene.addLayer(layer2);
  scene.addLayer(layer);
});
```

## Runtime environment

Before evaluating the example, await this setup in a page containing #container. Supporting files follow below.

```js
await (await import("/src/demo/setup.ts")).default({ container: document.getElementById('container'), path: "/examples/tile/basemap/demo/wms.ts" });
```


## src/demo/setup.ts

```ts
import type { DemoSetupContext } from '@antv/astro-theme-antv';
import * as District from 'district-data';
import { GLTFLoader } from 'three/examples/jsm/loaders/GLTFLoader.js';

export default async function setup({ container, path }: DemoSetupContext) {
  // Tool pages provide their own React layout and SDK imports.
  if (!path.startsWith('/examples/')) return;
  // Retain only the original globals still used by gallery examples.
  Object.assign(window, { District, GLTFLoader });
  const map = document.createElement('div');
  map.id = 'map';
  container.append(map);
  await import('./map.css');
  // Match the original gallery's shared AMap environment, including raw AMap demos.
  await import('./amap');
}
```

## src/demo/map.css

```css
#map {
  position: relative;
  width: 100%;
  height: 100%;
  min-height: 320px;
}

.labelclass {
  position: absolute;
  display: inline;
  cursor: pointer;
  background: rgb(255, 228, 120);
  border: solid 2px #fff;
  padding: 4px;
  white-space: nowrap;
  font:
    bold 12px/18px arial,
    sans-serif;
  color: #fff;
  border-radius: 50%;
  width: 40px;
  height: 40px;
  line-height: 30px;
  /* opacity: 0.7; */
  text-align: center;
  -webkit-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: none;
}
```

## src/demo/amap.ts

```ts
import AMapLoader from '@amap/amap-jsapi-loader';

// Preserve the site's development and production SDK registrations.
const credentials = import.meta.env.DEV
  ? { key: '6f025e700cbacbb0bb866712d20bb35c', securityJsCode: '290ddc4b0d33be7bc9b354bc6a4ca614' }
  : { key: 'f59bcf249433f8b05caaee19f349b3d7', securityJsCode: '2653011adeb04230b3a26cc9a780a800' };
window._AMapSecurityConfig = { securityJsCode: credentials.securityJsCode };
await AMapLoader.load({ key: credentials.key, version: '2.0', plugins: ['Map3D'] });
```
