req.file 和 req.body 在使用 multer 2.0 时不起作用

Question

multer.js

const multer = require("multer");

const upload = multer().single("avatar");

module. Exports = { upload };

用户路由.js

const { upload } = require("../middleware/multer");

 router.route("/register").post(upload, registerUser);

用于注册用户的控制器

const catchAsyncError = require("../../middleware/catchAsyncError");const ErrorHandler = require("../../utils/errorhandler");const cloudinary = require("cloudinary").v2;

// Register a userexports.registerUser = catchAsyncError(async (req, res, next) => {console.log(req.body);console.log(req.file);});

Answer 1

尝试修改模块。导出到module.exports并且 const upload = multer().single("avatar"); 可以改为 const upload = multer.single("avatar"); 希望这有效
