问题描述
我正在尝试在移动设备上测试我的React应用程序.我正在使用ngrok使本地服务器可用于其他设备，并且已将其与多种其他应用程序一起使用.但是，当我尝试将ngrok连接到React开发服务器时，出现错误:
I'm trying to test my React application on a mobile device. I'm using ngrok to make my local server available to other devices and have gotten this working with a variety of other applications. However, when I try to connect ngrok to the React dev server, I get the error:
Invalid Host Header
我相信默认情况下，React会阻止来自其他来源的所有请求.有什么想法吗?
I believe that React blocks all requests from another source by default. Any thoughts?
推荐答案
我遇到了类似的问题，发现有两种解决方案，它们可以直接在浏览器中查看应用程序
I'm encountering a similar issue and found two solutions that work as far as viewing the application directly in a browser
ngrok http 8080 -host-header="localhost:8080"
ngrok http --host-header=rewrite 8080
显然用您正在运行的任何端口替换8080
obviously replace 8080 with whatever port you're running on
当我在嵌入式页面中使用此解决方案时，此解决方案仍会引发错误，该错误会从react应用程序中获取bundle.js.我认为，因为它将标头重写为localhost，所以在嵌入时，它正在寻找的localhost是该应用程序不再运行的地方
this solution still raises an error when I use this in an embedded page, that pulls the bundle.js from the react app. I think since it rewrites the header to localhost, when this is embedded, it's looking to localhost, which the app is no longer running on
