Azure Web App 不启动节点服务器

Question

我正在通过 bitbucket 发布我的 typescript node.js/express azure 应用程序，看起来一切都在正确编译，但是 azure 没有启动应用程序。

一个可重复的存储库是here。我尝试将应用程序克隆到一个新的本地目录，然后运行 ​​deploy.cmd 并在输出文件夹中调用 node start，效果很好。

由于 Azure Web 应用程序上的 node.js 应用程序未侦听经典号码端口，因此在 iisnode 侦听的默认端口上响应 Web 请求。

您可以尝试修改您的main.ts 脚本：

let server: Server = new Server(process.env.PORT || 3000);

Azure Web Apps上对node.js应用程序的请求是通过iisnode处理的，你需要在根目录下创建一个web.config配置文件来配置入口文件，在你的场景中是bin\main.js .

web.config 内容示例：

<?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:

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

                    </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/main.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"/>

               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

               To debug your node.js application:
                 * set the debuggingEnabled option to "true"
                 * enable web sockets from the portal at https://manage.windowsazure.com/#Workspaces/WebsiteExtension/Website/garynodedeploy/configure
