無法將Node JS部署運行到Azure

Question

我遵循了本教程：

https://docs.microsoft.com/zh-cn/azure/app-service/app-service-web-get-started-nodejs

我已經使用“ Zip Deploy”工具部署了Express JS應用程序：

https：// [app_name_here] .scm.azurewebsites.net / ZipDeploy

當我嘗試調用公共API時，總是出現錯誤消息：“ 您要查找的資源已被刪除，名稱已更改或暫時不可用。 ”

奇怪的是，我的Express JS應用在本地運行得很好。 我已經嘗試過多次更改index.js來正確暴露我的API路由，但是在Azure上似乎沒有任何作用。 這是我當前的代碼。

由於我一直在合並3個不同的Express應用程序的邏輯，因此這確實有點混亂/混亂。

...

index.js

var express = require('express');
var cors = require('cors');
var bodyParser = require('body-parser');
var app = express();
var cookieParser = require('cookie-parser');
var path = require('path');
app.use(cors({ origin:'*' }));
app.set('port', (process.env.PORT || 5000));
app.use(bodyParser.json());

var indexRouter = require('./routes/index');
app.set('views', path.join(__dirname, 'views'));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));

app.use('/', indexRouter);

//Router imports
var chainCoreDevRoutes = require('./routes/chainCoreDevRoutes');
var mongoDevRoutes = require('./routes/mongoDevRoutes');
var stuffMartServiceRoutes = require('./routes/stuffMartServiceRoutes');
app.use('/dev/chainCore', chainCoreDevRoutes);
app.use('/dev/mongo', mongoDevRoutes);
app.use('/api', stuffMartServiceRoutes);

//app.get('*', function(request, response) { response.sendFile(path.join(__dirname, 'public/index.html')); });

app.listen(app.get('port'), function() {
  console.log('Node app is running wubbalubba dub dub! on port', app.get('port'));
});

...

路線/index.js

var express = require('express');
var router = express.Router();

/* GET home page. */
router.get('/', function(req, res, next) {
  res.render('index', { title: 'Express' });
});

module.exports = router;

...

web.config（Azure環境所需）

<configuration>
    <system.webServer>

        <!-- indicates that the index.js file is a node.js application 
        to be handled by the iisnode module -->

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

        <!-- adds index.js to the default document list to allow 
        URLs that only specify the application root location, 
        e.g. http://mysite.antarescloud.com/ -->

        <defaultDocument enabled="true">
            <files>
                <add value="index.js" />
            </files>
        </defaultDocument>

      </system.webServer>
</configuration>

我使用express generate創建了我的簡單項目，然后將其成功部署到azure。 請參考我的文件。

app.js

var createError = require('http-errors');
var express = require('express');
var path = require('path');
var cookieParser = require('cookie-parser');
var logger = require('morgan');

var indexRouter = require('./routes/index');
var usersRouter = require('./routes/users');

var app = express();

// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');

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

console.log("+++++++++++++++"+ app.get('port'));

app.use(logger('dev'));
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));

app.use('/', indexRouter);
app.use('/users', usersRouter);

// catch 404 and forward to error handler
app.use(function(req, res, next) {
  next(createError(404));
});

// error handler
app.use(function(err, req, res, next) {
  // set locals, only providing error in development
  res.locals.message = err.message;
  res.locals.error = req.app.get('env') === 'development' ? err : {};

  // render the error page
  res.status(err.status || 500);
  res.render('error');
});

module.exports = app;

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

我的解決方案： 不要遵循教程/博客文章

我使用了Visual Studio 2017，並找到了一個名為``基本Azure Node.js Express 4 App''的項目模板。 基礎項目進行得很順利，僅花費了5分鍾即可完成設置。

部署nodejs的最簡單方法是使用終端。

您只需像在普通計算機上一樣將項目克隆到服務器即可。 執行“ npm install”通過“ npm start”或“ node index.js”運行項目（取決於您的文件名）。 檢查程序是否在服務器中啟動，最好使用郵遞員測試api是否正常工作。 如果有錯誤，請修復它們。 如果不是，請在服務器計算機上安裝pm2。 然后使用“ pm2 index.js”啟動程序（相應地）。

每次對代碼進行更改時，最好鍵入“ pm2 restart all”以應用更改
