multer

问题 I'm rather new to multer/node/express/mongoose/... and I'm currently trying to upload multiple files from different inputs that have the same name (I generate the inputs using reactjs). Here's my React front-end: onSubmit = (e) => { e.preventDefault(); const {imges} = this.state; let formData = new FormData(); formData.append('imges', imges); axios.post('newuser', formData) .then(function (response) { console.log(response); }) .catch(function (error) { console.log(error); }); }

问题 Im trying to res.status.send a multer error message to postman when my file image exceeds 1MB. But when i try to run my code it only gives me this entire chunk of error message.

问题 I'm newer with Node.js and Express.js. I want to upload first a image into the server (directory: uploads/spots), and then (synchronous) upload the rest of form data in MongoDB. I'm using REST (Method Post) app.route('/spots').post(users.requiresLogin, spots.create); and I'm using Multer for updating the image into the server, and works. app.use(multer( { dest: './public/uploads/spots', onFileUploadStart: function (file) { var imagePath = file.path; gm(imagePath).resize(850, 850).quality(70)

问题 I am trying to submit a form which has a file input within it with a name of profileimage , i am using express 4, express generator and multer. In my app.js I added multer like so: var multer = require('multer'); var upload = multer({ dest: './uploads' }); The tutorial i am following actually sets up multer like so (after requiring it) but it gives me an error: app.use(multer({dest: './uploads'})); And in my routes folder inside the respective file I have the following: router.post('/register

I have even tried to hardcode the path with the image name but still its showing 404 error.

问题 does anyone know how to use tinyPNG's API with multer? The docs seem deceptively simple: var source = tinify.fromFile("unoptimized.jpg"); source.toFile("optimized.jpg"); though there's no clear indication of where this is meant to go, especially in something as convoluted as this: var storage = multer.diskStorage( { destination: function (req, file, callback) { callback(null, './uploads'); }, filename: function (req, file, callback) { //use date to guarantee name uniqueness callback(null,

问题 I have two node.js/express servers that communicate with each other with http. server A is also communicates with the browser and can handle file upload requests.

This is what i got so far, but i am unable to transfer the file between the servers, the file is

问题 I need to use python to send an image through post and then download it on the node.js server side. Python code: import requests from PIL import Image import json url = 'http://127.0.0.1:8080/ay' files = {'file': open('image.jpg', 'rb')} r = requests.post(url, data = files) Node.js code: var app = express(); app.use(bodyparser.json({ limit: '50mb' })); app.use(bodyparser.urlencoded({ limit: '50mb', extended: true })); app.post('/ay', function(req, res) { var base64Data = req.body.file require

问题 I am serving up my web application using NodeJS server (ExpressJS) currently. One of the new requirements is for the users to be able to upload large videos (potentially in gigs) to the server. They will later then be able to download them again. Could I achieve this with the current stack? I came across tutorials using Multer JS with "multipart/form-data" specified by the front-end. If I use this, would my Express be able to serve up other HTTP requests while writing a giant single video
