装置 Cesium
npm i cesium --save
配置
webpack.base.conf.js
减少别名 (cesium: path.resolve(__dirname, ‘../node_modules/cesium/Source’) )
resolve: {extensions: ['.js', '.vue', '.json'],
alias: {
'vue$': 'vue/dist/vue.esm.js',
'@': resolve('src'),
cesium: path.resolve(__dirname, '../node_modules/cesium/Source')
}
},
module 增加属性 unknownContextCritical: false, 否则会报上面这个 error:
require function is used in a way in which dependencies cannot be statically
module: {
.....
unknownContextCritical: false,
.....
}
webpack.dev.conf.js
plugins: [
....
// Copy Cesium Assets, Widgets, and Workers to a static directory
new CopyWebpackPlugin([{ from: path.join('node_modules/cesium/Source', '../Build/Cesium/Workers'), to: 'Workers' } ]),
new CopyWebpackPlugin([{ from: path.join('node_modules/cesium/Source', 'Assets'), to: 'Assets' } ]),
new CopyWebpackPlugin([{ from: path.join('node_modules/cesium/Source', 'Widgets'), to: 'Widgets' } ]),
new webpack.DefinePlugin({
// Define relative base path in cesium for loading assets
CESIUM_BASE_URL: JSON.stringify('')
}),
...
]
webpack.dev.conf.js
const cesiumSource = 'node_modules/cesium/Source'
const cesiumWorkers = '../Build/Cesium/Workers'
plugins: [

new CopyWebpackPlugin([{ from: path.join(cesiumSource, cesiumWorkers), to: 'Workers' }

new CopyWebpackPlugin([

to: 'ThirdParty/Workers'
}
]),
new webpack.DefinePlugin({
// Define relative base path in cesium for loading assets
// 定义 Cesium 从哪里加载资源,如果应用默认的 '',却变成了绝对路径了,所以这里应用'./', 应用相对路径
CESIUM_BASE_URL: JSON.stringify('./')
}),
...
]
留神应用的时候引入的形式为 reqiure.
Cesium1.6X 版当前不再反对 es6import
var Cesium = require("cesium/Cesium");
import "cesium/Widgets/widgets.css";
组件内应用
export const initCesium = () => {
{
window.cesiumViewer = new Cesium.Viewer("cesiumContainer", {
useDefaultRenderLoop: false,
animation: false,
baseLayerPicker: false,
fullscreenButton: false,
geocoder: false,
homeButton: false,
infoBox: false,
sceneModePicker: false,
selectionIndicator: false,
timeline: false,
navigationHelpButton: false,
terrainShadows: Cesium.ShadowMode.DISABLED,
// 高德图层
imageryProvider: new Cesium.UrlTemplateImageryProvider({
url:
"https://webst02.is.autonavi.com/appmaptile?style=6&x={x}&y={y}&z={z}",
}),
});
// // label
// 高德地图标注
cesiumViewer.imageryLayers.addImageryProvider(
new Cesium.UrlTemplateImageryProvider({
url:
"http://webst02.is.autonavi.com/appmaptile?x={x}&y={y}&z={z}&lang=zh_cn&size=1&scale=1&style=8",
})
);
// load the terrain
cesiumViewer.terrainProvider = Cesium.createWorldTerrain({
requestVertexNormals: true,
requestWaterMask: true,
});
let cp = new Cesium.Cartesian3(
4303414.154026048,
552161.235598733,
4660771.704035539
);
cesiumViewer.camera.setView({
destination: cp,
orientation: {
heading: 10,
pitch: -Cesium.Math.PI_OVER_TWO * 0.5,
roll: 0.0,
},
});
// 去除水印
setTimeout(() => {cesiumViewer._cesiumWidget._creditContainer.style.display = "none"; // clear the watermark mark}, 0);
}
实现!
