Vue项目部署在Spring Boot出现页面空白问题的解决方

// http request 拦截器
Axios.interceptors.request.use(
config => {
if (localStorage.getItem('id_token')) {
config.headers.Authorization = localStorage.getItem('id_token')
}
config.baseURL = '/api'
return config
},
err => {
return Promise.reject(err)
})

// Extract CSS when that option is specified
// (which is the case during production build)
if (options.extract) {
return ExtractTextPlugin.extract({
use: loaders,
fallback: 'vue-style-loader',
publicPath: '../../'
})
