Question

我尝试运行服务器，但收到此错误

var express = require('express');
var bodyParser = require('body-parser');
var fs = require('fs');
var http = require('http');
cors = require('cors');
var app = express();
app.use(cors());

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));

app.post('/', function(req, res) {
    let body = '';
    let dir = './example-dir';
    req.on('data', function(data) {
      body += data;
    });
    if (!fs.existsSync(dir)) {
      fs.mkdirSync(dir);
    }
    req.on('end', function() {
      fs.writeFile(dir + '/result.xml', body, function(err) {
        if (err) {
          return console.log(err);
        }
        res.send('You just created new xml file!')
      });
    });
  })

  const port = process.env.PORT || 3600;

  app.set('port', port);
  var server = http.createServer(app)

   server = app.listen(port, () => {
    console.log('Connected to port ' + port )
  })

我使用fs模块从角度写入数据，并保存在后端example-dir中的xml文件中我想从angular中获取xml并在后端的文件中发布
