1. 更改vue.config.js

publicPath: process.env.NODE_ENV === 'production' ? '/tyzfadmin' : '/',//开发和生产环境不一样，做个判断
outputDir: 'dist',
assetsDir: 'static',
lintOnSave: false,
runtimeCompiler: true,
productionSourceMap: false,
devServer: {
    port: port,
    open: true,
    overlay: {
      warnings: false,
      errors: true
    },
    proxy: {
      '/api': {
        target: 'http://127.0.0.1:8080', // 后端地址
        changeOrigin: true, // 开启代理，在本地创建一个虚拟服务端
        pathRewrite: {
          '^/api': '/'
        }
      }
    }
    // before: require('./mock/mock-server.js')
  },

2. 更改request.js

3. 更改 .env.development

# just a flag
ENV = 'development'

# base api
# VUE_APP_BASE_API = '/api'
VUE_APP_BASE_API = 'http://127.0.0.1:8080'//和proxy中的target一致
