Multer与Express.js

Question

将Multer与express.js一起使用时出现问题。所以这很好用：

const multer = require('multer');
let upload = multer({dest: 'uploads/'});

app.post('/upload', upload.single('image'), function (req, res, next) {
    console.log(req.file)
  // req.file is the `avatar` file
  // req.body will hold the text fields, if there were any
});

但是当我尝试这样做时，req.file is undefined：

const multer = require('multer');
let upload = multer({dest: 'uploads/'});
router.route('/', upload.single('image'))
    .post(function (req, res, next) {
        console.log(req.file);
        let memory = new Memory();
        Object.assign(memory, req.body);
        memory.save(function (err) {
            if (err) {
                return res.send(err);
            }
            res.json({message: 'Memory Created', memory});
        });
    })

只是想知道如果我想从我的routes.js分隔server.js，那么正确的语法是什么。

我也试过这个：

const multer = require('multer');
let upload = multer({dest: 'uploads/'});
router.route('/')
    .post(upload.single('image'), function (req, res, next) {
        console.log(req.file);
        let memory = new Memory();
        Object.assign(memory, req.body);
        memory.save(function (err) {
            if (err) {
                return res.send(err);
            }
            res.json({message: 'Memory Created', memory});
        });
    })

试试这个：

carbo2 <- carbo[,-4,-5,]
#or
carbo2 <- carbo[,c(-4,-5),]

确保帖子请求正文将文件附加到router.post('/', upload.single('image'), function (req, res, next) { console.log(req.file); // Do something with the file }); 属性。如果您使用Postman进行测试，它应该是这样的：
