由于发生内部服务器错误，无法显示该页面。 Node.js 天蓝色

Question

I have node.js application it works locally when I deployed it to Azure App service I get bellow error:

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

bellow is my server.js code:

 "use strict"; Object.defineProperty(exports, "__esModule", { value: true }); const express = require("express"); const bodyParser = require("body-parser"); const cookieParser = require("cookie-parser"); const errorhandler = require("errorhandler"); const morgan = require("morgan"); const cors = require("cors"); const router_1 = require("./routes/router"); const bunyan_logger_1 = require("./lib/loggers/bunyan.logger"); require("reflect-metadata"); //const database = require('./data/dbprovider/dbmssql'); class Server { constructor() { this.port = process.env.PORT || 3000; this.logger = new bunyan_logger_1.bunyanLogger(); this.app = express(); this.initExpressMiddleWare(); this.initCustomMiddleware(); this.initRoutes(); this.start(); } start() { this.app.listen(this.port, (err) => { if (err) { this.logger.StartLogger().error('In Server.TS start see details: ' + err); } else { console.log('Listening on http://localhost:%d', process.env.NODE_ENV, this.port); } }); } initExpressMiddleWare() { this.app.use(express.static(__dirname + '/public')); this.app.use(morgan('dev')); this.app.use(bodyParser.urlencoded({ extended: true })); this.app.use(bodyParser.json()); this.app.use(errorhandler()); this.app.use(cookieParser()); this.app.use(cors()); // Add headers this.app.use(function (req, res, next) { // Website you wish to allow to connect const allowOrigin = ['https://senserver4.azurewebsites.net','http://localhost:3000']; const origin = req.headers.origin; if (allowOrigin.indexOf(origin) > -1) { res.setHeader('Access-Control-Allow-Origin', origin); } // Request methods you wish to allow res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE'); // Request headers you wish to allow res.setHeader('Access-Control-Allow-Headers', 'X-Requested-With,content-type'); // Set to true if you need the website to include cookies in the requests sent // to the API (eg in case you use sessions) res.setHeader('Access-Control-Allow-Credentials', true); // Pass to next layer of middleware next(); }); //this.app.use(csrf({ cookie: true })); // this.app.use((req: { csrfToken: () => void; }, res: { locals: { _csrf: any; }; cookie: (arg0: string, arg1: any) => void; }, next: () => void) => { // let csrfToken = req.csrfToken(); // res.locals._csrf = csrfToken; // res.cookie('XSRF-TOKEN', csrfToken); // next(); // }); process.on('uncaughtException', (err) => { if (err) console.log(err, err.stack); }); } initCustomMiddleware() { if (process.platform === "win32") { require("readline").createInterface({ input: process.stdin, output: process.stdout }).on("SIGINT", () => { process.exit(1); }); } process.on('SIGINT', () => { process.exit(1); }); } initRoutes() { (new router_1.Router()).load(this.app, './controllers'); } } let server = new Server(); //# sourceMappingURL=server.js.map

I have created web.config file in root of my project below is the web.config code:

<?xml version="1.0" encoding="utf-8"?>

<configuration>
<appSettings>

</appSettings>
<system.webServer>
<staticContent>
  <mimeMap fileExtension=".svg" mimeType="image/svg+xml" />
</staticContent>

<modules runAllManagedModulesForAllRequests="false" />

<iisnode watchedFiles="web.config;*.js;routes\*.js;views\*.pug"/>

<handlers>
  <add name="iisnode" path="app.js" verb="*" modules="iisnode" />

</handlers>

  <requestFiltering>
    <hiddenSegments>
      <remove segment="bin" />
    </hiddenSegments>
  </requestFiltering>

    <rule name="NodeInspector" patternSyntax="ECMAScript" stopProcessing="true">

      <action type="Rewrite" url="app.js" />
    </rule>
  </rules>
</rewrite>
</system.webServer>

I have added my server.js in path mapping, but I could not resolve the issue.

Error I get in console:

This error is the common description of IIS server 500 error. It will be hard to find the root cause of the question by only the general description.

Please try below code of web.config to show the details that might helps you and don't comment your previous code.

<configuration>
    <system.webServer>
        <httpErrors errorMode="Detailed" />
        <asp scriptErrorSentToBrowser="true"/>
    </system.webServer>
    <system.web>
        <customErrors mode="Off"/>
        <compilation debug="true"/>
    </system.web>
</configuration>
