Estoy cargando algunos archivos en mi base de datos MongoDB, pero actualmente mi objeto fileInfo de middlware upload.js solo acepta una única cadena de depósito estática, ya que no puedo cambiar dinámicamente la cadena de nombre del depósito. ¿Cómo puedo pasar el middeware upload.js cualquier cadena que desee para el nombre del depósito?
ACCIÓN:
export const uploadPhoto = (img) => (dispatch) => { const formData = new FormData(); formData.append("file", img); const bucketName = "photos"; //HOW DO USE THIS BUCKET NAME IN THE upload.js Middlware? axios .post("/video/upload", formData) .then((res) => {}) .catch((err) => { console.log(err); }); };RUTAS:
const router = require("express").Router(); var mongoose = require("mongoose"); var Schema = mongoose.Schema; var ObjectId = require("mongodb").ObjectId; const { authUser } = require("../middleware/auth"); const uploadMulter = require("../middleware/upload"); //HOW DO I PASS DATA TO THE uploadMulter Middleware? router.post("/upload", authUser, uploadMulter, (req, res) => { console.log(req.file); });Subir software intermedio:
const path = require("path"); var mongoose = require("mongoose"); const crypto = require("crypto"); const multer = require("multer"); const { GridFsStorage } = require("multer-gridfs-storage"); const db = require("../config/.env").mongoURI; const storage = new GridFsStorage({ url: db, file: (req, file) => { return new Promise((resolve, reject) => { crypto.randomBytes(16, (err, buf) => { if (err) { return reject(err); } const filename = buf.toString("hex") + path.extname(file.originalname); const fileInfo = { filename: filename, bucketName: "HOW DO I CHANGE THE BUCKETNAME?", //<--? metadata: { author: req.user._id, }, }; resolve(fileInfo); }); }); }, }); const upload = multer({ storage }); module.exports = upload.single("file");Usé los parámetros de la URL, pero estoy seguro de que hay una mejor solución.
