将Express服务器发布到Azure

我是新来的 诺迪斯 . 我有一个非常简单的Express应用程序(只包含一个javascript文件(index.js),如下所示:

const express = require('express');
const bodyParser = require('body-parser');
const {
  dialogflow
} = require('actions-on-google');

const PORT = process.env.PORT || 4000;
const app = dialogflow({
  debug: true
});
const server = express()
  .use(bodyParser.urlencoded({
    extended: true
  }))
  .use(bodyParser.json(), app)
  .listen(PORT, () => console.log(`Listening on ${ PORT }`));

当我将此发布到Azure时,我使用此设置生成一个web.config文件:

-Handler iisnode -NodeStartFile index.js -appType node

它生成这样的web.config:

<?xml version="1.0" encoding="utf-8"?>
<!--
    This configuration file is required if iisnode is used to run node processes behind
    IIS or IIS Express.  For more information, visit:

<configuration>

    <webSocket enabled="false" />
    <handlers>
      <!-- Indicates that the server.js file is a node.js site to be handled by the iisnode module -->
      <add name="iisnode" path="index.js" verb="*" modules="iisnode"/>
    </handlers>
    <rewrite>
      <rules>
        <!-- Do not interfere with requests for node-inspector debugging -->
        <rule name="NodeInspector" patternSyntax="ECMAScript" stopProcessing="true">
          <match url="^server.js\/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="server.js"/>
        </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>

    <!-- Make sure error responses are left untouched -->
    <httpErrors existingResponse="PassThrough" />

    <!--
      You can control how Node is hosted within IIS using the following options:
        * watchedFiles: semi-colon separated list of files that will be watched for changes to restart the server
        * node_env: will be propagated to node as NODE_ENV environment variable
        * debuggingEnabled - controls whether the built-in debugger is enabled

      See https://github.com/tjanczuk/iisnode/blob/master/src/samples/configuration/web.config for a full list of options
    -->
    <!--<iisnode watchedFiles="web.config;*.js"/>-->
  </system.webServer>
</configuration>

但它似乎不起作用。有人知道我是否做错了什么吗?
