javascript - Multer Node.js 的文件上传 MIME 类型问题

Question

在我的项目中，我必须使用 Multer 上传一个 Photoshop 文件，但是当我输入 mime 类型的 photoshop、wave 和 mp3 文件时，我收到了这个错误:

Error: Mime type invalide
at DiskStorage.destination [as getDestination] (C:\Users\21653\Desktop\vagaBeats\back\src\midlleware\artworkImageUploader.js:14:21)
at DiskStorage._handleFile (C:\Users\21653\Desktop\vagaBeats\back\node_modules\multer\storage\disk.js:31:8)

at PartStream.emit (events.js:315:20)

这是我的代码:

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

const MIME_TYPE_MAP = {
    "image/png": "png",
    "image/jpeg": "jpg",
    "image/jpg": "jpg",
    "file/psd": "psd" // i got a problem with this MIME TYPE
};

const storage = multer.diskStorage({
    destination: (req, file, cb) => {
        const isValid = MIME_TYPE_MAP[file.mimetype];
        let error = new Error("Mime type invalide");
        if (isValid) {
            error = null;
        }
        cb(error, path.join(__dirname, '../../', 'images/artworkImages'));
    },
    filename: (req, file, cb) => {
        const name = file.originalname
            .toLowerCase()
            .split(" ")
            .join("-");
        console.log(file)
        const ext = MIME_TYPE_MAP[file.mimetype];
        cb(null, name + "-" + Date.now() + "." + ext);
    }
});

module.exports = multer({ storage: storage }).fields([
{ name: "Image"},
{name:"untagedartwork"},
{name:"psd_file"} //this is the file that i want to upload it to the server
]);

你能帮我解决这个问题吗

Answer 1

尝试将 file/psd 更改为其中的一些(第一个应该可以):

image/vnd.adobe.photoshop

application/x-photoshop

application/photoshop

application/psd

image/psd
