vue2.0项目集成Cesium的实现方法

(编辑:jimmy 日期: 2024/11/2 浏览:3 次 )

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' "htmlcode">
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
