在vue-cli4.x 中使用cesium1.8

1、vue-cli4.x + cesium1.8

2、配置vue.config.js

"use strict";
const path = require("path");
const defaultSettings = require("./src/settings.js");
​
​
// 1、引入cesium相关文件
const CopyWebpackPlugin = require("copy-webpack-plugin");
const webpack = require("webpack");
let cesiumSource = "./node_modules/cesium/Source";
let cesiumWorkers = "../Build/Cesium/Workers";
​
function resolve(dir) {
  return path.join(__dirname, dir);
}
​
const name = defaultSettings.title; // 网址标题
const port = 8013; // 端口配置
​
// All configuration item explanations can be find in https://cli.vuejs.org/config/
module.exports = {
  // hash 模式下可使用
  // publicPath: process.env.NODE_ENV === 'development' ? '/' : './',
  publicPath: "/",
  outputDir: "dist",
  assetsDir: "static",
  lintOnSave: process.env.NODE_ENV === "development",
  productionSourceMap: false,
  devServer: {
    port: port,
    open: true,
    overlay: {
      warnings: false,
      errors: true
    },
    proxy: {
      "/api": {
        target: process.env.VUE_APP_BASE_API,
        changeOrigin: true,
        pathRewrite: {
          "^/api": "api"
        }
      },
      "/auth": {
        target: process.env.VUE_APP_BASE_API,
        changeOrigin: true,
        pathRewrite: {
          "^/auth": "auth"
        }
      }
    }
  },
  configureWebpack: {
    // provide the app's title in webpack's name field, so that
    // it can be accessed in index.html to inject the correct title.
    name: name,
    // 2、cesium 进行配置
    resolve: {
      alias: {
        "@": resolve("src"),
        "@crud": resolve("src/components/Crud"),
        "cesium": path.resolve(__dirname, cesiumSource)
      }
    },
    plugins: [
      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({
        CESIUM_BASE_URL: JSON.stringify("/")
      })
    ]
  },
  chainWebpack(config) {
    config.plugins.delete("preload"); // TODO: need test
    config.plugins.delete("prefetch"); // TODO: need test
​
    // set svg-sprite-loader
    config.module
      .rule("svg")
      .exclude.add(resolve("src/assets/icons"))
      .end();
    config.module
      .rule("icons")
      .test(/.svg$/)
      .include.add(resolve("src/assets/icons"))
      .end()
      .use("svg-sprite-loader")
      .loader("svg-sprite-loader")
      .options({
        symbolId: "icon-[name]"
      })
      .end();
​
    // set preserveWhitespace
    config.module
      .rule("vue")
      .use("vue-loader")
      .loader("vue-loader")
      .tap(options => {
        options.compilerOptions.preserveWhitespace = true;
        return options;
      })
      .end();
​
    config
      // https://webpack.js.org/configuration/devtool/#development
      .when(process.env.NODE_ENV === "development",
        config => config.devtool("cheap-source-map")
      );
​
    config
      .when(process.env.NODE_ENV !== "development",
        config => {
          config
            .plugin("ScriptExtHtmlWebpackPlugin")
            .after("html")
            .use("script-ext-html-webpack-plugin", [{
              // `runtime` must same as runtimeChunk name. default is `runtime`
              inline: /runtime..*.js$/
            }])
            .end();
          config
            .optimization.splitChunks({
            chunks: "all",
            cacheGroups: {
              libs: {
                name: "chunk-libs",
                test: /[\/]node_modules[\/]/,
                priority: 10,
                chunks: "initial" // only package third parties that are initially dependent
              },
              elementUI: {
                name: "chunk-elementUI", // split elementUI into a single package
                priority: 20, // the weight needs to be larger than libs and app or it will be packaged into libs or app
                test: /[\/]node_modules[\/]_?element-ui(.*)/ // in order to adapt to cnpm
              },
              commons: {
                name: "chunk-commons",
                test: resolve("src/components"), // can customize your rules
                minChunks: 3, //  minimum common number
                priority: 5,
                reuseExistingChunk: true
              }
            }
          });
          config.optimization.runtimeChunk("single");
        }
      );
  },
  transpileDependencies: [
    "vue-echarts",
    "resize-detector"
  ]
};​

3、main.js 全局引入cesium相关文件

var cesium = require('cesium/Cesium');
var widgets= require('cesium/Widgets/widgets.css');
​
Vue.prototype.Cesium = cesium
Vue.prototype.widgets = widgets

4、 创建cesium.vue文件

<template>
  <div class="CesiumPage ">
    <div id="cesiumContainer"></div>
  </div>
</template>
​
<script>
export default {
  name: "CesiumPage",
  data() {
    return {};
  },
  mounted() {
    var viewer = new this.Cesium.Viewer("cesiumContainer", {});
​
  },
​
  methods: {}
};
</script>
​
<style lang="scss" scoped>
.CesiumPage {
   100%;
  height: 100%;
}
</style>

5、遇到的一些问题

Cannot GET /situation/index/Assets/approximateTerrainHeights.json

解决方法 在vue.config.js 进行相关的修改

new webpack.DefinePlugin({
  CESIUM_BASE_URL: JSON.stringify('/')   // ./ 改为 /
})
