Azure App service not working with custom routing in React-Redux web app - need wildcard virtual directories?

问题

I have custom routes like follows:

// @flow

import React, { PureComponent } from 'react';
import { Switch, Redirect } from 'react-router-dom';
import { withRouter } from 'react-router';

import { Route } from 'components/Routes';
import Story from 'pages/Story';
import Page404 from 'pages/404';

class Routes extends PureComponent<{}> {
  render() {
    return (
      <Switch>
        <Route exact path="/" render={props => <Story {...props} />} />
        <Route
          exact
          path="/chapter/:id"
          render={props => <Story {...props} />}
        />
        <Route path="/404" render={props => <Page404 {...props} />} />
        <Redirect to="/404" /* Must be the last one */ />
      </Switch>
    );
  }
}

export default withRouter(Routes);

This works fine in localhost, if I visit localhost:3000/chapter/3 the web app redirects successfully, unfortunately in live builds running on azure app services if I visit: mysite.azurewebsites.net/chapter/3 I'm given an error:

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

I'm running a Windows based App Service plan. I'm sure there's some option to set up redirecting, i.e. /chapter/* -> /www_siteroot/ but I haven't been able to figure out how to do it.

I fixed the issue by going to the app service settings and adding /chapter/1, /chapter/2, etc, etc under 'Virtual applications and directories' and directing them to site\wwwroot.

I'd prefer to have a wildcard option like /chapter/* but it doesn't seem to work and I get an error.

Since you're on Windows based App Service Plan, your Azure webapp is running under IIS with URL Rewriting module enabled. As such, you can create a simple URL Rewrite rule that directs all requests coming from https://mysite.azurewebsites.net/chapter/* to your site root in which case the client will receive your React/Redux application, and your React application would take care of all subsequent logic and rendering of content etc..

Here are the steps to create this URL Rewrite rule:

In Azure Portal, create FTP deployment credentials.
Locally on your computer, create a Web.config file with following content:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
            <rules>
                <rule name="Chapter-Redirect" stopProcessing="true">
                    <match url="chapter/*" />
                    <action type="Rewrite" url="/" />
                </rule>
            </rules>
        </rewrite>
    </system.webServer>
</configuration>

Open up FTP client (Filezilla is a good one) and login to your site and upload the Web.config file.
Test by visiting: https://mysite.azurewebsites.net/chapter/*

Here's more info on IIS URL Rewrite.

If you have your repo connected to the Azure Web App, then you can place this web.config file in the /public folder of a create-react-app project.

<?xml version="1.0"?>
<configuration>
    <system.webServer>

        <directoryBrowse enabled="false"/>

        <urlCompression doDynamicCompression="true" doStaticCompression="true"/>

        <!-- <staticContent>
            <clientCache cacheControlMaxAge="120.00:00:00" cacheControlMode="UseMaxAge"/>
        </staticContent> -->
        <caching enabled="true" enableKernelCache="true">
            <profiles>
                <add extension=".css" policy="CacheUntilChange" kernelCachePolicy="CacheUntilChange"/>
                <add extension=".js" policy="CacheUntilChange" kernelCachePolicy="CacheUntilChange"/>
                <add extension=".svg" policy="CacheUntilChange" kernelCachePolicy="CacheUntilChange"/>
                <add extension=".png" policy="CacheUntilChange" kernelCachePolicy="CacheUntilChange"/>
            </profiles>
        </caching>

        <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="/index.html" />
                </rule>
            </rules>
        </rewrite>

    </system.webServer>
</configuration>
