Azure Web 应用将 http 重定向到 https [英] Azure web app redirect http to https

问题描述

I use Azure cloud with web app and my server side written on nodejs. When web app receive a http request I want to redirect the request to https I found the solution. I put that to my web.config file inside the rules tag

        <rule name="Force HTTPS" enabled="true">
          <match url="(.*)" ignoreCase="false" />
          <conditions>
            <add input="{HTTPS}" pattern="off" />
          </conditions>
          <action type="Redirect" url="https://{HTTP_HOST}/{R:1}" appendQueryString="false" redirectType="Permanent" />
        </rule>

The problem is when I type in the browser "https://myURL.com" it redirect to main screen every thing ok, but when I change https to http "http://myURL.com" it redirect to https://myURL.com/" and add to the url "bin/www" according that the url looks like that "http://myURL.com/bin/www", the response is: page doesn't find.

The question is how to redirect a clear url without added data to the url?

Part of my web.config file:

<rewrite>
      <rules>
        <!-- Do not interfere with requests for node-inspector debugging -->
        <rule name="NodeInspector" patternSyntax="ECMAScript" stopProcessing="true">
          <match url="^bin/www/debug[/]?" />
        </rule>
        <!-- First we consider whether the incoming URL matches a physical file in the /public folder -->
        <rule name="StaticContent">
          <action type="Rewrite" url="public{REQUEST_URI}" />
        </rule>
        <!-- All other URLs are mapped to the node.js site entry point -->
        <rule name="DynamicContent">
          <conditions>
            <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="True" />
          </conditions>
          <action type="Rewrite" url="bin/www" />
        </rule>
        <!-- Redirect all traffic to SSL -->
         <rule name="Force HTTPS" enabled="true">
          <match url="(.*)" ignoreCase="false" />
          <conditions>
            <add input="{HTTPS}" pattern="off" />
          </conditions>
          <action type="Redirect" url="https://{HTTP_HOST}/{R:1}" appendQueryString="false" redirectType="Permanent" />
        </rule>
      </rules>
    </rewrite>
    <!-- 'bin' directory has no special meaning in node.js and apps can be placed in it -->
    <security>
      <requestFiltering>
        <hiddenSegments>
          <remove segment="bin" />
        </hiddenSegments>
      </requestFiltering>
    </security>

Thanks for answers, Michael.

Go to Azure portal and open the overview page of the (Web) App Service you wanna set to HTTPS only. In the sidebar, under the Settings section, there is an option for TLS/SSL Settings.

On clicking it, you will get an option on the screen to set your app's protocol to HTTPS only. There isn't any need to manually add separate ruleset for this.

This works on every tier of App Service Plan including the 'F'-Series (free subscription).

Note that, if you are adding any custom domain you also need to add corresponding SSL bindings, you can easily get them using LetsEncrypt or alike. If any of the custom hostnames for your app are missing SSL bindings, then:

When HTTPS Only is enabled clients accessing your app on those custom hostnames will see security warnings.

_{PS: I just saw that this question was asked about 3 years ago and that time maybe there was no direct option to do this. But even so, I'm posting my answer because on Google (as on February 2020) this question still ranks first among others regd. automatic HTTPS redirection in Azure.}
