Multer Error: Image url is not save in my Database

Question

起初我遇到了Multer: Unexpected field error，后来我修复到这里。除图像外，每个板列都保存在数据库中。是我的邮递员测试方法错了吗？或者我的代码有问题？如何在图板图像列中保存图像 url(路径)？

const upload = multer({
  storage: multer.diskStorage({
    destination(req, file, done) {
      done(null, "uploads/");
    },
    filename(req, file, done) {
      const ext = path.extname(file.originalname);
      const basename = path.basename(file.originalname, ext);
      done(null, basename + new Date().getTime() + ext);
    },
  }),
  limits: { fileSize: 5 * 1024 * 1024 }, // 5MB
});

router.post("/images", upload.single("image"), (req, res, next) => {
  res.json({ url: `/uploads/${req.file.filename}` });
});

router.post("/", upload.single("image"), async (req, res, next) => {
  try {
    const {
      category,
      title,
      description,
      tags,
      latitude,
      longitude,
      mainAddress,
      detailAddress,
    } = req.body;
    const createBoards = await boards.create({
      category,
      title,
      description,
      tags,
      latitude,
      longitude,
      mainAddress,
      detailAddress,
      image: req.body.url,
    });
    return res.status(200).json({ data: createBoards, message: "OK" });
  } catch (err) {
    return res.status(500).json({ message: "Error"});
  }
});

如果 url 是指 multer 为您上传的文件分配的实际路径，您可以在 file 对象上使用属性 path。有关所有可用属性，请参阅 this。

所以在你的情况下你可以这样做：

const createBoards = await boards.create({
      category,
      title,
      description,
      tags,
      latitude,
      longitude,
      mainAddress,
      detailAddress,
      image: req.file.path // to be safe you should maybe add a check if req.file is defined
    });
