vue引入cesium问题
作者:怎么吃不饱捏
这篇文章主要介绍了vue引入cesium问题,具有很好的参考价值,希望对大家有所帮助,如有错误或未考虑完全的地方,望不吝赐教
1.首先安装cesium
之前因为版本过高碰到过一些问题,所以后来一直安装的都是以下版本
npm install cesium@1.93
2. 配置
首先,配置webpack.base.conf.js,把全部代码都贴出来了,只需要取有配置cesium注释中的代码即可,以下配置同理。
'use strict' const path = require('path') const utils = require('./utils') const config = require('../config') const vueLoaderConfig = require('./vue-loader.conf') // 配置cesium----开始 const cesiumSource = '../node_modules/cesium/Source' const cesiumWorker = '../Build/Cesium/Workers' // 配置cesium----结束 function resolve(dir) { return path.join(__dirname, '..', dir) } module.exports = { context: path.resolve(__dirname, '../'), entry: { app: './src/main.js' }, output: { path: config.build.assetsRoot, filename: '[name].js', publicPath: process.env.NODE_ENV === 'production' ? config.build.assetsPublicPath : config.dev.assetsPublicPath, // 配置cesium----开始 sourcePrefix: ' ' // 配置cesium----结束 }, // 配置cesium----开始 amd: { toUrlUndefined: true }, // 配置cesium----结束 resolve: { extensions: ['.js', '.vue', '.json'], alias: { 'vue$': 'vue/dist/vue.esm.js', '@': resolve('src'), // 配置cesium----开始 'cesium': path.resolve(__dirname, cesiumSource) // 配置cesium----结束 } }, module: { rules: [ { test: /\.vue$/, loader: 'vue-loader', options: vueLoaderConfig }, { test: /\.js$/, loader: 'babel-loader', include: [resolve('src'), resolve('test'), resolve('node_modules/webpack-dev-server/client')] }, { test: /\.(png|jpe?g|gif|svg)(\?.*)?$/, loader: 'url-loader', options: { limit: 10000, name: utils.assetsPath('img/[name].[hash:7].[ext]') } }, { test: /\.(mp4|webm|ogg|mp3|wav|flac|aac)(\?.*)?$/, loader: 'url-loader', options: { limit: 10000, name: utils.assetsPath('media/[name].[hash:7].[ext]') } }, { test: /\.(woff2?|eot|ttf|otf)(\?.*)?$/, loader: 'url-loader', options: { limit: 10000, name: utils.assetsPath('fonts/[name].[hash:7].[ext]') } } ], // 配置cesium-----开始 unknownContextCritical: false // 配置cesium-----结束 }, node: { // prevent webpack from injecting useless setImmediate polyfill because Vue // source contains it (although only uses it if it's native). setImmediate: false, // prevent webpack from injecting mocks to Node native modules // that does not make sense for the client dgram: 'empty', fs: 'empty', net: 'empty', tls: 'empty', child_process: 'empty' } }
其次,配置 webpack.dev.conf.js
'use strict' const utils = require('./utils') const webpack = require('webpack') const config = require('../config') const merge = require('webpack-merge') const path = require('path') const baseWebpackConfig = require('./webpack.base.conf') const CopyWebpackPlugin = require('copy-webpack-plugin') const HtmlWebpackPlugin = require('html-webpack-plugin') const FriendlyErrorsPlugin = require('friendly-errors-webpack-plugin') const portfinder = require('portfinder') // 配置cesium----开始 const cesiumSource = 'node_modules/cesium/Source' const cesiumWorkers = '../Build/Cesium/Workers' // 配置cesium----结束 const HOST = process.env.HOST const PORT = process.env.PORT && Number(process.env.PORT) const devWebpackConfig = merge(baseWebpackConfig, { module: { rules: utils.styleLoaders({ sourceMap: config.dev.cssSourceMap, usePostCSS: true }) }, // cheap-module-eval-source-map is faster for development devtool: config.dev.devtool, // these devServer options should be customized in /config/index.js devServer: { clientLogLevel: 'warning', historyApiFallback: { rewrites: [ { from: /.*/, to: path.posix.join(config.dev.assetsPublicPath, 'index.html') }, ], }, hot: true, contentBase: false, // since we use CopyWebpackPlugin. compress: true, host: HOST || config.dev.host, port: PORT || config.dev.port, open: config.dev.autoOpenBrowser, overlay: config.dev.errorOverlay ? { warnings: false, errors: true } : false, publicPath: config.dev.assetsPublicPath, proxy: config.dev.proxyTable, quiet: true, // necessary for FriendlyErrorsPlugin watchOptions: { poll: config.dev.poll, } }, plugins: [ new webpack.DefinePlugin({ 'process.env': require('../config/dev.env') }), 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 }), // copy custom static assets new CopyWebpackPlugin([ { from: path.resolve(__dirname, '../static'), to: config.dev.assetsSubDirectory, ignore: ['.*'] } ]), // 配置cesium----开始 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('') }) // 配置cesium----结束 ] }) module.exports = new Promise((resolve, reject) => { portfinder.basePort = process.env.PORT || config.dev.port portfinder.getPort((err, port) => { if (err) { reject(err) } else { // publish the new Port, necessary for e2e tests process.env.PORT = port // add port to devServer config devWebpackConfig.devServer.port = port // Add FriendlyErrorsPlugin devWebpackConfig.plugins.push(new FriendlyErrorsPlugin({ compilationSuccessInfo: { messages: [`Your application is running here: http://${devWebpackConfig.devServer.host}:${port}`], }, onErrors: config.dev.notifyOnErrors ? utils.createNotifierCallback() : undefined })) resolve(devWebpackConfig) } }) })
最后,配置 webpack.prod.conf.js
'use strict' const path = require('path') const utils = require('./utils') const webpack = require('webpack') const config = require('../config') const merge = require('webpack-merge') const baseWebpackConfig = require('./webpack.base.conf') const CopyWebpackPlugin = require('copy-webpack-plugin') const HtmlWebpackPlugin = require('html-webpack-plugin') const ExtractTextPlugin = require('extract-text-webpack-plugin') const OptimizeCSSPlugin = require('optimize-css-assets-webpack-plugin') const UglifyJsPlugin = require('uglifyjs-webpack-plugin') // 配置cesium----开始 const cesiumSource = 'node_modules/cesium/Source' const cesiumWorkers = '../Build/Cesium/Workers' // 配置cesium----结束 const env = require('../config/prod.env') const webpackConfig = merge(baseWebpackConfig, { module: { rules: utils.styleLoaders({ sourceMap: config.build.productionSourceMap, extract: true, usePostCSS: true }) }, devtool: config.build.productionSourceMap ? config.build.devtool : false, output: { path: config.build.assetsRoot, filename: utils.assetsPath('js/[name].[chunkhash].js'), chunkFilename: utils.assetsPath('js/[id].[chunkhash].js') }, plugins: [ // http://vuejs.github.io/vue-loader/en/workflow/production.html new webpack.DefinePlugin({ 'process.env': env }), new UglifyJsPlugin({ uglifyOptions: { compress: { warnings: false } }, sourceMap: config.build.productionSourceMap, parallel: true }), // extract css into its own file new ExtractTextPlugin({ filename: utils.assetsPath('css/[name].[contenthash].css'), // Setting the following option to `false` will not extract CSS from codesplit chunks. // Their CSS will instead be inserted dynamically with style-loader when the codesplit chunk has been loaded by webpack. // It's currently set to `true` because we are seeing that sourcemaps are included in the codesplit bundle as well when it's `false`, // increasing file size: https://github.com/vuejs-templates/webpack/issues/1110 allChunks: true, }), // Compress extracted CSS. We are using this plugin so that possible // duplicated CSS from different components can be deduped. new OptimizeCSSPlugin({ cssProcessorOptions: config.build.productionSourceMap ? { safe: true, map: { inline: false } } : { safe: true } }), // generate dist index.html with correct asset hash for caching. // you can customize output by editing /index.html // see https://github.com/ampedandwired/html-webpack-plugin new HtmlWebpackPlugin({ filename: config.build.index, template: 'index.html', inject: true, minify: { removeComments: true, collapseWhitespace: true, removeAttributeQuotes: true // more options: // https://github.com/kangax/html-minifier#options-quick-reference }, // necessary to consistently work with multiple chunks via CommonsChunkPlugin chunksSortMode: 'dependency' }), // keep module.id stable when vendor modules does not change new webpack.HashedModuleIdsPlugin(), // enable scope hoisting new webpack.optimize.ModuleConcatenationPlugin(), // split vendor js into its own file new webpack.optimize.CommonsChunkPlugin({ name: 'vendor', minChunks (module) { // any required modules inside node_modules are extracted to vendor return ( module.resource && /\.js$/.test(module.resource) && module.resource.indexOf( path.join(__dirname, '../node_modules') ) === 0 ) } }), // extract webpack runtime and module manifest to its own file in order to // prevent vendor hash from being updated whenever app bundle is updated new webpack.optimize.CommonsChunkPlugin({ name: 'manifest', minChunks: Infinity }), // This instance extracts shared chunks from code splitted chunks and bundles them // in a separate chunk, similar to the vendor chunk // see: https://webpack.js.org/plugins/commons-chunk-plugin/#extra-async-commons-chunk new webpack.optimize.CommonsChunkPlugin({ name: 'app', async: 'vendor-async', children: true, minChunks: 3 }), // copy custom static assets new CopyWebpackPlugin([ { from: path.resolve(__dirname, '../static'), to: config.build.assetsSubDirectory, ignore: ['.*'] } ]), // 配置cesium----开始 new CopyWebpackPlugin([ { from: path.join(cesiumSource, cesiumWorkers), to: 'Workers' } ]), new CopyWebpackPlugin([ { from: path.join(cesiumSource, 'Assets'), to: 'Assets' } ]), new CopyWebpackPlugin([ { from: path.join(cesiumSource, 'Widgets'), to: 'Widgets' } ]), new webpack.DefinePlugin({ CESIUM_BASE_URL: JSON.stringify('./') }) // 配置cesium----结束 ] }) if (config.build.productionGzip) { const CompressionWebpackPlugin = require('compression-webpack-plugin') webpackConfig.plugins.push( new CompressionWebpackPlugin({ asset: '[path].gz[query]', algorithm: 'gzip', test: new RegExp( '\\.(' + config.build.productionGzipExtensions.join('|') + ')$' ), threshold: 10240, minRatio: 0.8 }) ) } if (config.build.bundleAnalyzerReport) { const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin webpackConfig.plugins.push(new BundleAnalyzerPlugin()) } module.exports = webpackConfig
3.在要用到cesium的页面
引入cesium及其样式
const Cesium = require("cesium/Cesium"); import widgets from "cesium/Widgets/widgets.css";
4.最后再写上创建地球的方法就成功啦
记得调用哦!
init() { //此处填写你在cesium中注册的token Cesium.Ion.defaultAccessToken = " xxxx"; // 渲染cesium viewer = new Cesium.Viewer("cesiumContainer", { geocoder: false, //搜索框 animation: false, //左下角的动画控件的显示 shouldAnimate: false, //控制模型动画 timeline: false, //底部的时间轴 fullscreenButton: false, //右下角的全屏按钮 selectionIndicator: false, //选择指示器 homeButton: true, infoBox: false, //信息面板 baseLayerPicker: false, //图层选择按钮 navigationHelpButton: false, //右上角的帮助按钮 sceneModePicker: false, //3d/2d 模式切换按钮 // terrainProvider: Cesium.createWorldTerrain(), // 提供地形 使用Cesium在线Ion地形 shouldAnimate: true, // 表示实体是运行状态 }); viewer._cesiumWidget._creditContainer.style.display = "none"; //隐藏logo版权 },
