在iis和windows azure上运行expressjs 4的内部错误

标签: node.js azure express

我使用节点提供的Web服务器在本地运行基本的express 4应用程序。

我尝试在Webmatrix中查看/编辑并使用IIS,然后我可以将其作为节点应用程序上传到Azure。 Azure的模板使用旧版本的node和express。

使用IIS从Webmatrix运行时 - 当发布到Azure时,我会收到以下内容:

HRESULT: 0x2
HTTP status: 500
HTTP reason: Internal Server Error

我认为该问题与web.config文件有某种关系,但我发现的所有文章和修正都已过时且未解决问题。

我的web.config文件:

<configuration>
<system.webServer>

<handlers>
  <!-- indicates that the app.js file is a node.js application to be handled by the iisnode module -->
  <add name="iisnode" path="app.js" verb="*" modules="iisnode" />
</handlers>

<rewrite>
  <rules>

    <!-- Don't interfere with requests for node-inspector debugging -->
    <rule name="NodeInspector" patternSyntax="ECMAScript" stopProcessing="true">
      <match url="^app.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 application entry point -->
    <rule name="DynamicContent">
      <conditions>
        <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="True" />
      </conditions>
      <action type="Rewrite" url="app.js" />
    </rule>
  </rules>
</rewrite>

<!-- You can control how Node is hosted within IIS using the following options -->

我已联系Azure团队,他们已经开始讨论,但我更加相信stackoverflow用户可以提供的内容。

@Matthew,

这是我的猜测,我认为你没有配置你的应用程序,以便在部署到azure应用程序服务时收听正确的端口。您将需要执行类似于以下代码的操作,以便从环境中获取端口号&#34; process.env.port&#34;

var app = require('express')();
var port = process.env.port || 8080; // 8080 for local or whatever number u want
var listener = app.listen(port, function(){
    console.log('Listening on port ' + port); 
});
