Question

我一直在处理下面的路由文件。但是，它本质上是一个照片应用程序，我可以将数据存储在MondoDB中。但是，当我运行下面的代码时，终端会继续说出意外的令牌。然后。我在这里错过了什么吗？

var express = require('express');
var router = express.Router();
var app = express();
var multer = require('multer');
var upload = multer({dest: 'public/images/'});
var Photo = require ('../models/travelModels');

router.get('/', (req, res, next)=>{
    Photo.find({})
      .then((photos) =>{
       res.render('lists', {
       list: photos
     });
  });
});

router.post('/', upload.single('image'), (req, res, next)=>{

   var path = "/static/images" + req.file.filename;
   var item  = {
      destination: req.body.destination,
      description: req.body.description,
      imageurl: path,
      mimetype: req.file.mimetype,
      filename: req.file.filename
    }

  // save photo in database
    var entry = new Photo (item);
    entry.save();
       .then(()=>{
        res.redirect('/mylist')
      });
    // or catch error
       .catch((err)=>{
          if (err){
            console.log(err);
         }
      });
});


module.exports = router;

Answer 1

您需要在then之前和catch

之前删除分号

var entry = new Photo (item);
entry.save()
 .then(()=>{
  res.redirect('/mylist')
 })
 .catch((err)=>{
    if (err){
      console.log(err);
    }
 });

意外的令牌错误.then |承诺|的NodeJS
