Multer 上传不是 swagger UI / Nodejs 中的功能

Question

我正在使用 Multer 在 swagger UI 中制作上传文件系统。

我发现了这个屏幕截图问题 - 上传不是一个功能

这是类别。 uploads.js

const multer = require("multer");
const Path = require("path");


const storage = multer.diskStorage({
                  destination: function (req, file, callback) {
                                    callback(null, "./uploads/categories");



                  },
                  filename: function (req, file, callback) {
                                    callback(null, Date.now() + "-" + file.originalname);
                  }


});

const fileFilter = (req, file, callback) => {
                  const acceptableExt = [".png", ".jpg", ".jpeg"];
                  if (!acceptableExt.includes(Path.extname(file.originalname))) {


                                    return callback(new Error("Only .png, .jpg and .jpeg format allowed!"));

                  }

                  const fileSize = parseInt(req.headers["content-length"]);

                  if (fileSize > 1048576) {
                                    return callback(new Error("File Size Big"));
                                    
                  }

                  callback(null, true);
};

let upload = multer({
                  storage: storage,
                  fileFilter: fileFilter,
                  fileSize: 1048576,
});

module.exports = upload.single("categoryImage");

抱歉，格式化程序无法工作......

这是我的Category.service.js

const { category } = require("../models/category.model");

async function createCategory(params, callback) {
                  if (!params.categoryName) {
                                    return callback(
          {
                   message: "Category Name Required",
              },
                  ""
                                    );
                  }


                  const model = new category(params);
                  model.save().then((response) => {
                                    return callback(null, response);
                  }).catch((error) => {
                                    return callback(error);
                  });

};

这是我的类别。控制器.js

const categoriesService = require("../services/category.service");
const upload = ("../middleware/category.upload");



exports.create = (req, res, next) => {
                  
   upload(req, res, function (err) {
      if (err) {
         next(err);
      }
      else {    
         
         const path = req.file != undefined ? req.file.path.replace(/\\/g, "/"
         ) : "";

         var model = {
            categoryName: req.body.categoryName,
            categoryDescription: res.body.categoryDescription,
            categoryImage: path != "" ? "/" + path : "",
         };

         categoriesService.createCategory(model, (error, results) => {
            if (error) {
               return next(error);
            }
            else {
               return res.status(200).send({  
                  message: "Success",
                  data: results,
               });
            }
         });
      }
   });
};

请帮忙我该如何解决这个问题？

Answer 1

module.exports = upload.single("categoryImage");

在上面的代码中只需导出

--upload

这是上面代码的更新代码

module.exports = upload;
