我使用的是一个环境,一个Cloud9.io ubuntu VM Online IDE,我通过对此错误进行故障排除,只是通过Webpack dev服务器运行应用程序 .
我推出它:
webpack-dev-server -d --watch --history-api-fallback --host $IP --port $PORT
$ IP是一个变量,其主机地址为$ PORT,具有端口号 .
在Cloud 9中部署应用程序时,我被指示使用这些变量,因为它们具有默认的IP和PORT信息 .
服务器启动并编译代码,没问题,但它没有向我显示索引文件 . 只有一个空白屏幕,"Invalid Host header"为文本 .
这是请求:
GET / HTTP/1.1

由于我的主机设置,Webpack dev服务器正在返回此状态 . 在webpack-dev-server / lib / Server.js第60行 . 来自https://github.com/webpack/webpack-dev-server
我的问题是我如何设置正确通过此检查 . 任何帮助将不胜感激 .

我用这个解决了,因为webpack-dev-server 2.4.4添加了主机检查
编辑:请注意,此修复程序是不安全的 .
有关安全的解决方案,请参阅以下答案:https://stackoverflow.com/a/43621275/5425585
我发现,我需要将devServer的
public
属性设置为我的请求的主机值 . 因为它将显示在该外部地址 .所以我在webpack.config.js中需要这个
另一种解决方案是在CLI上使用它:
webpack-dev-server --public $ C9_HOSTNAME < - 用于Cloud9外部IP的var
这对我有用:
在webpack.config.js中的devServer下添加allowedHosts:
我不需要使用--host或--public params .
使用webpack-dev-server时,将此配置添加到webpack配置文件中(您仍然可以将主机指定为0.0.0.0) .
如果您在C9上使用create-react-app,只需运行此命令即可启动
并从您的主机名访问应用程序(例如,在终端输入
$C_HOSTNAME
以获取主机名)
