如果您使用的是IIS / Windows主机，您应该将此添加到您的web.config文件中。

<configuration>
      <system.webServer>
        <handlers>
          <add name="iisnode" path="app.js" verb="*" modules="iisnode" />
        </handlers>
    
        <rewrite>
          <rules>
            <rule name="myapp">
            <match url="/*" />
            <action type="Rewrite" url="app.js" />
          </rule>
    <!-- Don't interfere with requests for node-inspector debugging -->
        <rule name="NodeInspector" patternSyntax="ECMAScript" stopProcessing="true">
           <match url="^app.js\/debug[\/]?" />
        </rule>    
      </rules>   
    </rewrite>  
  </system.webServer>
 </configuration>
