Migrating away from bodyParser() in Express app with busboy?

阅读更多关于 Migrating away from bodyParser() in Express app with busboy?

问题 Being a newbie in Nodejs, I jumped right into writing a simple app without really reading up on good security practices. I just found out that using bodyParser() for all routes is actually a bad thing because it allows for DOS attack using multipart files. A recommended fix is to only load specific modules depending on the route. ie, for multipart fileupload, use multipart . For regular POST without file uploads (ie, text form submission), use express.json(), express.urlencoded() . Or another

node.js server not responding while large file upload with express and busboy

问题 I am developping an file sharing platform with node.js and express.js, using busboy. It works nicely at this time but uploading large file. If I do, the server doesn't accept any new request while the large file is uploaded. I that normal ? If it is, how to improve this behavior, even if that means the upload will take more time... For now I develop and test on localhost on a pretty good PC (asus i7/8G) on ubuntu. When I start uploadind a large file, and open a new tab to go to the app, the

Firebase Cloud Functions and Busboy not parsing fields or files

阅读更多关于 Firebase Cloud Functions and Busboy not parsing fields or files

问题 I've been doing some experiments with Firebase Cloud Functions and Express, and I am stuck with a problem when I try to process a FormData with Busboy. It seems that I only get one big malformed text field with all the data in it, including also any binary data of files I try to upload (i.e. gibberish ascii characters) . I've tried the different solutions found online, even here on SO, and I see that all of them are built around the example provided by Google about Multipart Data: https:/

What's the difference between the 'field' and the 'file' events in busboy?

阅读更多关于 What's the difference between the 'field' and the 'file' events in busboy?

问题 Busboy is the middleware I'm using to upload a file. Using an html form inside Chrome, I can upload files (using the 'file' event) but when an android client tries to upload a file, it doesn't trigger the 'file' event, it triggers the 'field' event instead. Here the code snippet I am using on the server side: import express from 'express'; import busboy from 'connect-busboy'; const app = express(); const busUpload = (req, res)=> { req.busboy.on('file', function(fieldname, file, filename,

Transform upload with NodeJS Multer

阅读更多关于 Transform upload with NodeJS Multer

问题 I'm currently implementing a file/image upload service for my users. I want to transform these images (resize/optimize) before uploading to my s3 bucket. What I'm currently doing: Using a multipart form on my frontend (I think the actual implementation doesn't matter here..) and the multer and multer-s3 packages on my backend. Here my implementation stripped down to the important parts. // SETUP var multer = require('multer'); var s3 = require('multer-s3'); var storage = s3({ dirname: 'user

Streaming an uploaded file to an HTTP request

阅读更多关于 Streaming an uploaded file to an HTTP request

My goal is to accept an uploaded file and stream it to Wistia using the the Wistia Upload API . I need to be able to add fields to the HTTP request, and I don't want the file to touch the disk. I'm using Node , Express , Request , and Busboy . The code below has two console.log statements. The first returns [Error: not implemented] and the second returns [Error: form-data: not implemented] . I'm new to streaming in Node, so I'm probably doing something fundamentally wrong. Any help would be much appreciated. app.use("/upload", function(req, res, next) { var writeStream = new stream.Writable();

Node JS - Stream data from Busboy to AWS S3

阅读更多关于 Node JS - Stream data from Busboy to AWS S3

问题 I am trying to upload a file to s3 via ec2. My first approach was - upload file to ec2 completely and then upload that file to s3. This approach is not good because transfer time from ec2 to s3 is waste of time. Currently I am trying to use busboy upload stream to s3 upload stream so that uploading to ec2 and then ec2 to s3 will be done simultaneously as s3 "upload" method support stream as upload Body. Here is my code - router.post('/s3StreamUpload', function(req, res, next) { var busboy =

busboy-connect fires on finish before the end of save file (node.js , express)

阅读更多关于 busboy-connect fires on finish before the end of save file (node.js , express)

问题 I use busboy connect to get the upload data from my client. I try to save the data and then on.finish to return status ok to the server. The problem is that the on.finish fires before the end of the file saving. Have I done something wrong or that's the way the module works? server-side code : console.log("upload started dirname ", __dirname); var fstream; var result = []; var number_of_files = 1; req.pipe(req.busboy); req.busboy.on('field', function(fieldname, val) { field_obj = {} field_obj

Post file from one server to another,using node.js , needle , busboy/multer

I would like to move a small image from one server to another (both running node). As I search, I haven't found enough. This post remains unanswered. As I started experimenting I wrote the following to the first server : app.post("/move_img", function(req, res) { console.log("post handled"); fs.readFile(__dirname + "/img_to_move.jpg", function(err, data) { if (err) throw err; console.log(data); needle.post(server2 + "/post_img", { data: data, name : "test.jpg" }, function(result) { console.log(result); res.send("ok"); }); }); }); This part seems to be working as I could be writing the data in
