Node.js azure web 應用程序無法訪問我的路由

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');
});

以及以下 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:

    <handlers>
      <!-- Indicates that the server.js file is a node.js site to be handled by the iisnode module -->

      <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>

現在我將它添加到我的服務器，使它看起來像這樣：

然后我嘗試使用永遠forever start index.js來啟動服務器，然后我去我的網站並嘗試一條路線，但它只是給了我一個錯誤代碼 500。

誰能告訴我我做錯了什么？

Answer 1

根據我的經驗，您可以像下面那樣修改index.js試：

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，對於 500 錯誤，您需要啟用stdout和stderr日志記錄以進行故障排除並查看日志內容。 要啟用調試，請按照下列步驟操作：

1. 如果不存在，則在您的根文件夾 ( D:\\home\\site\\wwwroot ) 中創建文件iisnode.yml 。

2. 向其中添加以下幾行。

   loggingEnabled: true logDirectory: iisnode

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