vue 前后端分离配置代理

[有意思点]

先上代码：

dev: {
    env: require('./dev.env'),
    contextPath: 'mb',
    // Various Dev Server settings
    port: 8080, // can be overwritten by process.env.PORT, if port is in use, a free one will be determined
    host: 'localhost', // can be overwritten by process.env.HOST
    // Paths
    autoOpenBrowser: true,
    assetsSubDirectory: 'static',
    assetsPublicPath: '/',
    proxyTable: {
      '/mb': {
        target: 'http://127.0.0.1:8008',
        source: false
      }
    },
    cssSourceMap: true
  }

在config文件夹中index.js，配置dev的contextPath（这个与后台服务的contextPath一致）,
在proxyTable中配置后台服务
