我收到一个“无效的主机头”的消息，我运行的应用程序作出反应的的WebPack开发服务器上Cloud9.io

Question

我使用的是一个环境，一个Cloud9.io Ubuntu的虚拟机联机IDE

时，我已经被解决此减少错误，只是用Webpack dev服务器运行应用程序。

webpack-dev-server -d --watch --history-api-fallback --host $IP --port $PORT 

$ IP是具有主机地址 $端口具有端口号的变量：

我启动它。

我奉命在云9部署应用程序时使用这些增值经销商，因为他们有默认的IP和端口信息。

服务器启动并编译代码，没问题，它是不是虽然给我看索引文件。只有一个带有“无效主机标题”的空白屏幕作为文本。

这是请求：

} 

的WebPack开发服务器是由于我的主机设置而返回。在webpack-dev-server/lib/Server.js行60.从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。

Answer 1

我发现，我需要设置devServer的public财产，我的请求的主机值。因为它将显示在该外部地址。

所以，我需要这在我的webpack.config.js

devServer: { 
    compress: true, 
    public: 'store-client-nestroia1.c9users.io' // That solved it 
} 

另一种解决方案是使用它的CLI：

的WebPack-DEV-服务器--public $ C9_HOSTNAME < - VAR的CLOUD9外部IP

Answer 2

我解决了这个问题，怎么一回事，因为的WebPack-DEV-服务器2.4.4添加主机检查

devServer: { 

    compress: true, 

    disableHostCheck: true, // That solved it 

}  

Answer 3

编辑node_modules/webpack-dev-server/lib/Server.js线425 更新的行

return true; 

Answer 4

如果您正在使用创建反应的应用程式中C9只要运行这个命令来启动

npm run start --public $C9_HOSTNAME 

而且无论从任何主机名访问应用程序是
