仅在部署到Azure Web App后才反应JS App路由问题 [英] React JS App Routing Issue Only After Deploying to Azure Web App

问题描述

我有一个带有React Router的React JS应用.在开发过程中，npm启动，我没有任何问题.我照常访问以下位置.

I have a React JS app, with React Router.During development, npm start, I get no issues. I visit the following location as usual.

http://localhost:3000 

并且由于路由代码，它变为

and due to the routing code, it becomes

http://localhost:3000/index

，应用加载就好了.此时，

and the app loads just fine. At this point,

• 我重新加载，应用继续正常运行.
• 我手动链接或加载"http://localhost:3000/index"，应用运行正常.

然后，稍后，我进行npm构建，进入该构建文件夹，然后再次进行npm启动.该应用程序运行正常.我重新加载，运行正常.到目前为止没有什么可抱怨的.

Then, later, I do an npm build, go inside this build folder, and do an npm start, again, the same thing. the app runs just fine. I reload, it runs fine. Nothing to complain so far.

问题部分.

然后，我决定将应用程序部署到Azure Web应用程序.该应用程序运行良好.我去了这个网站.

I then decided to deploy the app to an azure web app. The app runs fine. I go to this site.

https://randomstuffreactjsappsept24.azurewebsites.net

并且由于路由代码，它变为

and due, to routing code, it becomes

https://randomstuffreactjsappsept24.azurewebsites.net/index

然后，该网站就会加载.

And, the website loads.

这时，如果我遇到重载(问题！)，它将尝试重载，

At this point, if I hit reload (problem!!), it will try to reload,

https://randomstuffreactjsappsept24.azurewebsites.net/index

我收到以下错误消息.

The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.

现在，在这一点上，如果我删除'/index'并加载原始网址，

Now, at this point, if I remove the '/index' and load the original url,

https://randomstuffreactjsappsept24.azurewebsites.net

该站点加载正常，没问题.请注意，您可以自己查看.这是一个直播网站.(但是，当然，由于路由代码，它变成了)

The site loads just fine, no problem. Note, you can see it for yourself. this is a live site. (but of course, due to routing code, it becomes)

https://randomstuffreactjsappsept24.azurewebsites.net/index

现在，只要我不重新加载网站，该网站就会继续运行.为什么会这样?

Now, as long as I dont reload the website, the website continues to run. Why is this happening?

这是项目中index.js主页的代码.

Here is the code for the main index.js page from the project.

ReactDOM.render(
  <BrowserRouter>
    <Switch>
      <Route path="/index" render={(props) => <Index {...props} />} />
      <Redirect to="/index" />
    </Switch>
  </BrowserRouter>,
  document.getElementById("root")
);

更新2

我决定尝试另一个完全由另一个来源创建的react应用.再次，同样的问题，我有一个现场网站可供展示.

I decided to try another react app, created by another source entirely. Once again, same issue, and I have a live site to show.

• 我访问了 https://auth0tokenreactjsappprivatesept25.azurewebsites.net/external-api ，从网络应用程序中，它可以正常工作.如果我此时要重新加载，它会说您正在寻找的资源已被删除，名称已更改或暂时不可用."
• 我从应用程序内部访问http://localhost:3000/external-api，效果很好.而且，如果我要重新加载，则加载就很好.

• I visit, https://auth0tokenreactjsappprivatesept25.azurewebsites.net/external-api, from within the web app, it works fine. If i were to reload at this point, it will say "The resource you are looking for has been removed, had its name changed, or is temporarily unavailable."
• I visit, http://localhost:3000/external-api, from within the app, it works fine. AND, If I were to reload, it loads just fine.

因此，它绝对是仅"的.部署后发生.

So, its definitely "only" happening after deployment.

推荐答案

根据:

According to: https://github.com/react-boilerplate/react-boilerplate/issues/1612 You would have to place the: Simply place the following file called web.config under your wwwroot folder:

<?xml version="1.0"?> <configuration> <system.webServer> <rewrite> <rules> <rule name="React Routes" stopProcessing="true"> <match url=".*" /> <conditions logicalGrouping="MatchAll"> <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" /> <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" /> <add input="{REQUEST_URI}" pattern="^/(api)" negate="true" /> </conditions> <action type="Rewrite" url="/" /> </rule> </rules> </rewrite> </system.webServer> </configuration>

将web.config文件添加到azure目录

Add the web.config file to the azure directory
