基础环境安装
node.js(检测npm包管理工具 npm -v)
Webpack安装(全局安装 npm install webpack -g)(检测安装成功: webpack -v)
vue-cli脚手架构建工具(npm install vue-cli -g)(检测:vue -V)
vue项目搭建
命令行cd进入项目构建文件目录级,执行vue init webpack project_name(项目名不可用中文),按提示输入相应内容,项目文件构建完成。
cd到项目目录内,安装项目依赖npm install,项目启动npm run dev
浏览器进入地址http://localhost:8080,打开项目页面,搭建完成
Cesium环境搭建
命令行在项目目录下,安装cesium组件库 npm install cesium --save
修改 在build/webpack.base.conf.js,
定义cesium源码路径
const cesiumSource = '../node_modules/cesium/Source'
var webpack = require('webpack')
在module.exports中output添加sourcePrefix: ’ ',让webpack正确处理多行字符串
output: {
path: config.build.assetsRoot,
filename: '[name].js',
publicPath: process.env.NODE_ENV === 'production'
? config.build.assetsPublicPath
: config.dev.assetsPublicPath,
sourcePrefix: ' '
},
在resolve中设置cesium别名
resolve: {
extensions: ['.js', '.vue', '.json'],
alias: {
'vue$': 'vue/dist/vue.esm.js',
'@': resolve('src'),
'cesium': path.resolve(__dirname, cesiumSource)
}
},
module里添加
module: {
rules: [...],
unknownContextCritical: false,
},
修改 webpack.dev.conf.js 文件
配置路径
const cesiumSource = 'node_modules/cesium/Source'
const cesiumWorkers = '../Build/Cesium/Workers'
在plugins下面添加如下插件
new CopyWebpackPlugin([{ from: path.join(cesiumSource, cesiumWorkers), to: 'Workers' }]),
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 webpack.DefinePlugin({
// Define relative base path in cesium for loading assets
CESIUM_BASE_URL: JSON.stringify('')
})
修改 webpack.prod.conf.js文件
配置路径
const cesiumSource = 'node_modules/cesium/Source'
const cesiumWorkers = '../Build/Cesium/Workers'
在plugins添加如下插件,与dev配置略有不同
new CopyWebpackPlugin([ { from: path.join(cesiumSource, cesiumWorkers), to: 'Workers' } ]),
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 webpack.DefinePlugin({
// Define relative base path in cesium for loading assets
//定义 Cesium 从哪里加载资源,如果使用默认的'',却变成了绝对路径了,所以这里使用'./',使用相对路径
CESIUM_BASE_URL: JSON.stringify('./')
})
修改config里index.js中build中的assetsPublicPath为"./"
// Paths
assetsRoot: path.resolve(__dirname, '../dist'),
assetsSubDirectory: 'static',
assetsPublicPath: "./",
配置main.js
import Cesium from 'cesium/Cesium'
import widgets from 'cesium/Widgets/widgets.css'
Vue.prototype.Cesium = Cesium
Vue.prototype.widgets = widgets
div引入,使用cesium。修改components下的HelloWorld.vue组件
<template>
<div id="container" class="box">
<div id="cesiumContainer"></div>
</div>
</template>
<script>
import Cesium from 'cesium/Cesium'
export default {
name: 'cesiumPage',
data () {
return {
}
},
mounted(){
//var Cesium = this.Cesium;
var cesiumContainer = document.getElementById("cesiumContainer");
var viewer = new Cesium.Viewer("cesiumContainer",{
//加载在线谷歌地图
imageryProvider: new Cesium.UrlTemplateImageryProvider({
url:"http://www.google.cn/maps/vt?lyrs=s&x={x}&y={y}&z={z}"
})
})
}
}
</script>
<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>
html,
body,
#cesiumContainer {
width: 100%;
height: 100%;
margin: 0;
padding: 0;
overflow: hidden;
}
#app {
font-family: "Avenir" , Helvetica, Arial, sans-serif;
-webkit-font-smoothing: antialiased;
-moz-osx-font-smoothing: grayscale;
color: #2c3e50;
width: 100%;
height: 100%;
}
.box {
height: 100%;
}
</style>
执行npm run dev , 打开浏览器运行项目(localhost:8081)(默认端口号为8080,到config/index.js里可修改)
这里提示构造CesiumWidget时出错
在这里有两种解决办法
第一种是修改 build/webpack.base.conf.js,
module里添加
module: {
rules: [...],
unknownContextCritical: false,
unknownContextRegExp: /^.\/.*$/,
},
第二种还是修改build/webpack.base.conf.js,
output: {
path: config.build.assetsRoot,
filename: '[name].js',
publicPath: process.env.NODE_ENV === 'production'
? config.build.assetsPublicPath
: config.dev.assetsPublicPath,
sourcePrefix: ' '
},
//在Cesium中启用Webpack时使用Require
amd: {
toUrlUndefined: true
},
我个人倾向于第二种0.0;
修改完之后运行 如下
