使用 Multer 和 Node 将多个文件上传到 mongoDB

Question

如何使用 Node 和 multer 将多个文件上传到 mongoDB。这是我尝试（当然不成功）来处理它。 uploadImg.array() 似乎运行良好，因为它在本地创建文件。问题是我无法在 mongoDB

中创建新的上传

router.post("/img", auth, uploadImg.array("path", 12), async (req, res) => {
  try {
    Promise.all(
      req.files.map(async (file) => {
        const newUpload = new Uploads({
          _id: new Types.ObjectId(),
          path: file.path,
          owner: req.user.userId,
        });

        return await newUpload.save();
      })
    );

    res.status(201).json(newUpload);
  } catch (e) {
    res
      .status(500)
      .json({ message: "Something went wrong in /uploads/img", error: e });
  }
});

req.files 看起来像这样：

 [
   {
     fieldname: 'path',
     originalname: 'cover.jpg',
     encoding: '7bit',
     mimetype: 'image/jpeg',
     destination: 'uploads/',
     filename: '1608637632307cover.jpg',
     path: 'uploads\1608637632307cover.jpg',
     size: 77716
   },
   {
     fieldname: 'path',
     originalname: 'mainImg.jpg',
     encoding: '7bit',
     mimetype: 'image/jpeg',
     destination: 'uploads/',
     filename: '1608637632310mainImg.jpg',
     path: 'uploads\1608637632310mainImg.jpg',
     size: 111086
   }
 ]

有什么想法吗？ :)

此解决方案非常有效，您只需处理 res.status:

router.post("/img", auth, uploadImg.array("path", 12), async (req, res) => {
  Promise.all(
    req.files.map(async (file) => {
      const newUpload = new Uploads({
        _id: new Types.ObjectId(),
        path: file.path,
        owner: req.user.userId,
      });

      return await newUpload.save();
    })
  )
    .then(res.status(201).json("files successfully uploaded"))
    .catch((e) => {
      res
        .status(500)
        .json({ message: "Something went wrong in /uploads/img", error: e });
    });
});
