create-react-app之Invalid Host Header

【create-react-app之Invalid Host Header】

1、When you enable the `proxy` option, you opt into a more strict set of host checks. This is necessary because leaving the backend open to remote hosts makes your computer vulnerable to DNS rebinding attacks.

　　you will see this error in the browser after enabling the `proxy` option:

　　　　>Invalid Host header

2、To work around it, you can specify your public development host in a file called `.env.development` in the root of your project:

　　```

　　　　HOST=mypublicdevhost.com

　　```

　　If you restart the development server now and load the app from the specified host, it should work.

3、If you are still having issues or if you’re using a more exotic environment like a cloud editor, you can bypass the host check completely by adding a line to `.env.development.local`.
