Node.js multer中的mp4文件上传问题

Question

我正在尝试在Node.js中使用multer上传mp4文件

import React, { useState } from "react";
import Axios from "axios";


function VideoUploadPage() {

const onDrop = (files) => {
    let formData = new FormData();
    const config = {
      header: { "content-type": "multipart/form-data" },
    };
    formData.append("file", files[0]);
    console.log(files);

    Axios.post("/api/video/uploadfiles", formData, config).then((response) => {
      if (response.data.success) {
        console.log(response.data);
      } else {
        alert("비디오 업로드를 실패 했습니다.");
      }
    });
  };

}

const express = require("express");
const router = express.Router();
const multer = require("multer");
const path = require("path");
const ffmpeg = require("fluent-ffmpeg");



let storage = multer.diskStorage({
  destination: (req, file, cb) => {
    cb(null, "uploads/");
  },
  filename: (req, file, cb) => {
    cb(null, `${Date.now()}_${file.originalname}`);
  },
  fileFilter: (req, file, cb) => {
    const ext = path.extname(file.originalname);
    if (ext !== ".mp4") {
      return cb(res.status(400).end("only mp4 is allowed"), false);
    }
    cb(null, true);
  },
});

const upload = multer({ storage: storage }).single("file");

router.post("/uploadfiles", (req, res) => {
  upload(req, res, (err) => {
    if (err) {
      return res.json({ success: false, err });
    }
    return res.json({
      success: true,
      url: res.req.file.path,
      fileName: res.req.file.filename,
    });
  });
});

例如：“C：//~~~/Uploads”

你知道吗？

Answer 1

您可以使用path.resolve（process.cwd（）+'path tile upload folder')；

例如：path.resolve（process.cwd（）+'/uploads')；
