在Azure网站中运行nodeJS站点

Question

我正在尝试在Windows Azure网站中运行nodeJS站点。 我只是git推了两个文件：

server.js package.json

我所有的模块来自npm install 。 它在本地工作正常，但当我浏览WA网站时，我得到：

The page cannot be displayed because an internal server error has occurred.

我用CLI来获取尾部日志，但我只是看到了这个：

<h3>HTTP Error 500.0 - Internal Server Error</h3> 
<h4>The page cannot be displayed because an internal server error has occurred.</h4> 
</div> 
<div class="content-container"> 
<fieldset><h4>Most likely causes:</h4> 
<ul>    <li>IIS received the request; however, an internal error occurred during the processing of the request. The root cause of this error depends on which module handles the request and what was happening in the worker process when this error occurred.</li>    <li>IIS was not able to access the web.config file for the Web site or application. This can occur if the NTFS permissions are set incorrectly.</li>    <li>IIS was not able to process configuration for the Web site or application.</li>     <li>The authenticated user does not have permission to use this DLL.</li>   <li>The request is mapped to a managed handler but the .NET Extensibility Feature is not installed.</li> </ul> 
</fieldset> 
</div> 
<div class="content-container"> 
<fieldset><h4>Things you can try:</h4> 
<ul>    <li>Ensure that the NTFS permissions for the web.config file are correct and allow access to the Web server's machine account.</li>     <li>Check the event logs to see if any additional information was logged.</li>  <li>Verify the permissions for the DLL.</li>    <li>Install the .NET Extensibility feature if the request is mapped to a managed handler.</li>  <li>Create a tracing rule to track failed requests for this HTTP status code.

没有看到你的实际server.js代码（你应该在你的问题中插入），我只能猜测可能是什么问题。 所以...我的猜测是你的server.js没有在正确的端口上听（当然，我可能是错的......）。

在node.js开发人员部分的WindowsAzure.com站点上的node.js教程中，有一个“Hello World”示例，显示了如何从环境中获取端口：

var http = require('http')
var port = process.env.PORT || 1337;
http.createServer(function(req, res) {
    res.writeHead(200, { 'Content-Type': 'text/plain' });
    res.end('Hello World\n');
}).listen(port);

您不能让您的服务器在端口80上侦听。您需要从process.env.PORT获取正确的端口。

希望这是你的问题......

作为旁注，请确保您正在转换任何ES6。 我在浏览器中打开了Visual Studio编辑器，它立即抱怨这个。 因此调整为我解决了500。
