无法使用Multer上传文件

Multer应该将文件数据放在req.file中，但是req.file是未定义的。

Here is the request I'm making with the file:

Here is my nodejs code:

//routes.js
import candidatesRouter from './candidates';
export default function routes(app) {
  app.use('/v1/candidates', candidatesRouter);
}

//candidates.js
const multer = require('multer');
const upload = multer({ dest: 'uploads/' });
export default express
  .Router()
  .post('/:userId/documents/:objectKey', upload.any(), (req, res, next) => {
    console.log(req.body); // undefined
    console.log(req.file); // undefined
    console.log(req.files); // []
  });

有没有人有任何想法？谢谢！

试试这个

const fileUpload = require('express-fileupload');
app.use(fileUpload());

然后再次检查req.files
