在config文件夹下index.js中配置：

module.exports = {
    dev: {
        // Paths
        assetsSubDirectory: 'static',
        assetsPublicPath: '/',
        proxyTable: {
          '/': {
            target: '接口地址',
            changeOrigin: true,
            secure: false,
            pathRewrite: { 
                '^/': '' 
            }
          }
    },
}
