Node.js azure web 应用程序无法访问我的路线

Question

我有以下index.js 文件：

const express = require('express');
const app = express();
const router = express.Router();
var cors = require('cors');
var http = require('http').Server(app);
const fileUpload = require('express-fileupload');
app.use(fileUpload());
const uploadRoute = require('./routes/upload');

app.use(cors());

app.use(uploadRoute(router));
app.use(router);
http.listen(80, function () {
    console.log('listening on *:80');
});

还有以下 web.config 文件：

    <?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">

        <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="index.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>

现在我将它添加到我的服务器，使其看起来像这样：

然后我尝试使用永久forever start index.js 启动服务器 然后我去我的网站尝试一条路线，但它只给了我一个错误代码 500。

谁能告诉我我做错了什么？

根据我的经验，您可以修改您的 index.js 如下所示，然后重试：

const express = require('express');
const app = express();
const router = express.Router();
var cors = require('cors');
var http = require('http').Server(app);
const fileUpload = require('express-fileupload');
app.use(fileUpload());
const uploadRoute = require('./routes/upload');

app.use(cors());

app.use(uploadRoute(router));
app.use(router);

app.set('port', process.env.PORT || 5000);

app.listen(app.get('port'), function(){
          console.log('Express server listening on port ' + app.get('port'));
          });

此外，对于 500 错误，您需要启用 stdout 和 stderr 的日志记录以进行故障排除并查看日志内容。要启用调试，请按照以下步骤操作：

1. 如果不存在，则在您的根文件夹 (D:\home\site\wwwroot) 中创建文件 iisnode.yml。

2. 在其中添加以下行。

   日志记录启用：真 日志目录：iisnode

完成后，您可以在D:\home\site\wwwroot\iisnode 中找到日志。
