vue2安装cesium并使用

一、安装

1.安装cesium

npm install cesium@1.95.0 -S

2.安装所需

npm install copy-webpack-plugin@10.2.4 -D

二、配置

1.配置vue.config.js

vue 中引入cesium 需要用copy-webpack-plugin 把一些文件拷贝到打包目录

// vue.config.js
const CopyWebpackPlugin = require("copy-webpack-plugin");
const webpack = require("webpack");const path = require("path"); //引入path模块
function resolve(dir) {return path.join(__dirname, dir); //path.join(__dirname)设置绝对路径
}
module.exports = {lintOnSave: false,// publicPath: '/xayw_jc',productionSourceMap: false, //关闭 SourceMap，webpack：//// publicPath://   process.env.NODE_ENV === "production" ? "/\n" + "vue-cesium-example/" : "/",configureWebpack: {resolve: {alias: {"@": resolve("src"),},},plugins: [// Copy Cesium Assets, Widgets, and Workers to a static directorynew CopyWebpackPlugin({patterns: [{from: "node_modules/cesium/Build/Cesium/Workers",to: "Workers"},{from: "node_modules/cesium/Build/Cesium/ThirdParty",to: "ThirdParty",},{from: "node_modules/cesium/Build/Cesium/Assets",to: "Assets"},{from: "node_modules/cesium/Build/Cesium/Widgets",to: "Widgets"},],}),new webpack.DefinePlugin({// Define relative base path in cesium for loading assetsCESIUM_BASE_URL: JSON.stringify(""),}),// new BundleAnalyzerPlugin() //解开可查看项目打包分布情况],module: {// Removes these errors: "Critical dependency: require function is used in a way in which dependencies cannot be statically extracted"// https://github.com/AnalyticalGraphicsInc/cesium-webpack-example/issues/6unknownContextCritical: false,unknownContextRegExp: /\/cesium\/cesium\/Source\/Core\/buildModuleUrl\.js/,rules: [{test: /\.mjs$/,include: /node_modules/,type: "javascript/auto"},]},},chainWebpack: (config) => {config.module.rule("svg").exclude.add(resolve("src/icons")).end();config.module.rule("icons").test(/\.svg$/).include.add(resolve("src/icons")).end().use("svg-sprite-loader").loader("svg-sprite-loader").options({symbolId: "icon-[name]",}).end();},
};

2.配置css

①高版本的cesium引入widgets.css会报错，需要到node_modules/cesium/package.json添加

 "./widgets.css":"./Source/Widgets/widgets.css",

②main.js引入

import 'cesium/widgets.css';

 3.获取Access Tokens

 cesium   网站获取token，并复制到项目中

三、开发

cesium页面代码如下

<template><div id="cesiumContainer"></div>
</template>
<script>
import * as Cesium from 'cesium'
export default {name: 'HelloWorld',mounted(){this.initCesium()},methods:{initCesium (){Cesium.Ion.defaultAccessToken = "网站复制的token"let viewer = new Cesium.Viewer('cesiumContainer')}}
}
</script>
<style scoped></style>

运行效果如下
