vue 开发踩过的坑，devServer proxy配置通配符，报错SyntaxError: Invalid regular expression: /**/*.html/: Nothing to repeat

官网文档：

proxy('**', {...}) 匹配所有路径, 所有请求都会被代理.
proxy('**/*.html', {...}) 匹配所有以html结尾的路径,
proxy('/*.html', {...}) 匹配所有/目录下的html结尾的路径
proxy('/api/**/*.html', {...}) **匹配所有/api目录下的任意子目录里的html结尾的路径**
proxy(['/api/**', '/ajax/**'], {...}) **匹配所有/api目录下的任意子目录的路径**
proxy(['/api/**', '!**/bad.json'], {...}) 

坑

环境：vue/cli4

vue.config.js配置

module.exports={
    publicPath:'/dist/',
    devServer:{
        open: true, //是否自动弹出浏览器页面
        host: "localhost", 
        port: '8080',
        https: false,
        hotOnly: false, 
        proxy: {
            '**/*.html': {
                target: 'http://www.baidu.com', //API服务器的地址
                changeOrigin: true
            }
        }
    }
}

报错：

报错代码：return pathname.match(context)
解决办法
使用js 标准正则
