vue2.0项目集成Cesium的实现方法

前端  /  管理员 发布于 4年前   1045

安装cesium

在已有项目中执行,

npm i cesium

修改配置

build/webpack.base.conf.js

1、定义 Cesium 源码路径

const cesiumSource = '../node_modules/cesium/Source''use strict'const path = require('path')const utils = require('./utils')const config = require('../config')const vueLoaderConfig = require('./vue-loader.conf')//--cesium--配置const cesiumSource = '../node_modules/cesium/Source'; 

2、在output 里加入sourcePrefix: ' ' 让webpack 正确处理多行字符串

3、配置 amd参数

4、module中在rules后添加 unknownContextCritical: false,

module.exports = {  context: path.resolve(__dirname, '../'),  entry: {    app: ["babel-polyfill", './src/main.js']  },  output: {    path: config.build.assetsRoot,    filename: '[name].js',    publicPath: process.env.NODE_ENV === 'production' ?      config.build.assetsPublicPath : config.dev.assetsPublicPath,    //--cesium--配置------------------------------------    sourcePrefix: ' '  },  //--cesium--配置----------------------------------------  amd:{    toUrlUndefined: true  },  resolve: {    extensions: ['.js', '.vue', '.json'],    alias: {      'vue$': 'vue/dist/vue.esm.js',      '@': resolve('src'),      //--cesium--配置      'cesium': path.resolve(__dirname, cesiumSource)    }  },  module: {    rules: [    ...    ],    //--cesium--配置-------------------------------------    //unknownContextRegExp: /^.\/.*$/    unknownContextCritical: false,  }}

build/webpack.dev.conf.js

1、定义 Cesium 源码路径和Cesium Workers 路径

const cesiumSource = 'node_modules/cesium/Source'const cesiumWorkers = '../Build/Cesium/Workers' 

（注意这里的 node_modules 与webpack.base.conf.js的不同，前面没有../）

2、定义CESIUM_BASE_URL变量

3、在plugins 中加入下面插件,拷贝静态资源

plugins: [  new webpack.DefinePlugin({   'process.env': require('../config/dev.env'),   //--cesium--配置-------------------------------------------   'CESIUM_BASE_URL': JSON.stringify('')   }),  new webpack.HotModuleReplacementPlugin(),  new webpack.NamedModulesPlugin(), // HMR shows correct file names in console on update.  new webpack.NoEmitOnErrorsPlugin(),  // https://github.com/ampedandwired/html-webpack-plugin  new HtmlWebpackPlugin({   filename: 'index.html',   template: 'index.html',   inject: true  }),  //--cesium--配置---------------------------------------------  new CopyWebpackPlugin([ { from: path.join(cesiumSource, cesiumWorkers), to: 'Workers' } ]),   //flag  new CopyWebpackPlugin([ { from: path.join(cesiumSource, 'Assets'), to: 'Assets' } ]),  new CopyWebpackPlugin([ { from: path.join(cesiumSource, 'Widgets'), to: 'Widgets' } ]),  new CopyWebpackPlugin([ { from: path.join(cesiumSource, 'ThirdParty/Workers'), to: 'ThirdParty/Workers' } ]),  new CopyWebpackPlugin([ { from: 'ThirdParty', to: 'ThirdParty' } ]),  // copy custom static assets  new CopyWebpackPlugin([   {    from: path.resolve(__dirname, '../static'),    to: config.dev.assetsSubDirectory,    ignore: ['.*']   }  ]) ]

build/webpack.prod.conf.js

1、定义

 const cesiumSource = 'node_modules/cesium/Source'; const cesiumWorkers = '../Build/Cesium/Workers';

2、定义'CESIUM_BASE_URL'变量

3、在plugins 中加入下面插件,拷贝静态资源

plugins: [  // http://vuejs.github.io/vue-loader/en/workflow/production.html  new webpack.DefinePlugin({   'process.env': env,   //--cesium--配置--------------------------------------   'CESIUM_BASE_URL': JSON.stringify('static')  }),  ...  new HtmlWebpackPlugin({    ...  },  //--cesium--配置--------------------------------------  new CopyWebpackPlugin([ { from: path.join(cesiumSource, cesiumWorkers), to: 'static/Workers' } ]),//flag  new CopyWebpackPlugin([ { from: path.join(cesiumSource, 'Assets'), to: 'static/Assets' } ]),  new CopyWebpackPlugin([ { from: path.join(cesiumSource, 'Widgets'), to: 'static/Widgets' } ]),  new CopyWebpackPlugin([ { from: path.join(cesiumSource, 'ThirdParty/Workers'), to: 'ThirdParty/Workers' } ]),  new CopyWebpackPlugin([ { from: 'ThirdParty', to: 'ThirdParty' } ]),  ...

ThirdParty

在项目根目录新建文件夹ThirdParty，放入draco_decoder.wasm文件，在加载gltf模型文件需要用到
