Invalid Host/Origin header
问题表述比较明确：请求的header中Host或Origin没有通过检测。
本人是开发环境下webpack-dev-server热更新出现的问题。主要是本地开发使用了charles代理，浏览器使用域名访问代理到本机的localhost:8080。热更新是vue-cli原生的配置
// these devServer options should be customized in /config/index.js devServer: { ... hot: true, host: HOST || config.dev.host, port: PORT || config.dev.port, ... }
网上的建议大多是添加一个“disableHostCheck: true”，官网都说了不推荐：不建议这样做，因为不检查主机的应用容易受到DNS重新绑定攻击的攻击。
使用另外一个东东：allowedHosts来解决就行。
至于要实现热更新，热更新请求也要代理到localhost:8080 【端口根据自己的情况定】
