使用Express和multer成功上传后的确认

Question

我正在尝试使用express.js和multer上传文件。我的代码如下所示。

const storage = multer.diskStorage({
    destination: function ( req, file, cb ) {
        cb( null, './uploads/' );
    },
    filename: function ( req, file, cb ) {
        cb( null, file.originalname+ '-' + Date.now() );
    }
});

const fileFilter = ( req, file, cb ) => {
    if (file.mimetype === 'image/jpeg' || file.mimetype === 'image/png' ) {
        cb( null, true );
    } else {
        cb( new Error('Try to upload .jpeg or .png file.'), false );
    }
}

const upload = multer({
    storage: storage,
    limits: {
        fileSize: 1024 * 1024 * 5
    },
    fileFilter: fileFilter
});

router.post('/upload', upload.single('addressImage'), addressController.uploadImage);


const uploadImage = (req, res, next) => {
  // I would like to confirm file uploaded perfectly here.
}

如何确认文件已正确上传？我想返回上传的文件名。
