首先，在static下，创建config.json文件
config.json代码如下：
//config.json
{
"BASE_URL": "http://localhost:8087"
}
然后在main.js中，加入如下代码：
let startApp = function () {
axios.get('./static/config.json').then((res) => {
Vue.prototype.BASE_URL = res.data.BASE_URL;//将BASE_URL挂载在Vue原型
new Vue({
el: '#app',
router,
store,
components: { App },
template: '<App/>',
})
})
}
startApp()
同时修改config目录下的index.js文件中的如下内容：
build: {
// Template for index.html
index: path.resolve(__dirname, '../dist/'+ projectName +'/index.html'),
// Paths
assetsRoot: path.resolve(__dirname, '../dist/' + projectName),
assetsSubDirectory: 'static',
assetsPublicPath: './',
/**
* Source Maps
*/
productionSourceMap: false,
// https://webpack.js.org/configuration/devtool/#production
devtool: '#source-map',
// Gzip off by default as many popular static hosts such as
// Surge or Netlify already gzip all static assets for you.
// Before setting to `true`, make sure to:
// npm install --save-dev compression-webpack-plugin
productionGzip: false,
productionGzipExtensions: ['js', 'css'],
// Run the build command with an extra argument to
// View the bundle analyzer report after build finishes:
// `npm run build --report`
// Set to `true` or `false` to always turn it on or off
bundleAnalyzerReport: process.env.npm_config_report
}
