问题 So I am using html-pdf to convert my html and here is my code: var pdf = require('html-pdf') var html = 'somehtmlfile.html' pdf.create(html).toBuffer(function (err, buffer) { if (err) { console.log(err) } else { console.log(buffer) var pdfBuffer = new Buffer(buffer) res.setHeader('Content-disposition', 'inline; filename="test.pdf"'); res.setHeader('Content-type', 'application/pdf'); res.send(pdfBuffer) } } I am not getting any PDF file to be downloader nor any output of a pdf file in the

问题 I built a Firebase HTTP Event function with Node and Express. The function is working, but when I invoke the function on the client side I get 403 Forbidden . The first time I invoked the function I was asked to sign in with a Google account. I signed in with the same account I use for Firebase, but when I invoked the function I got: Screenshot of 403 error I looked at the use roles on Google cloud platform and the permission to invoke the function is set to allUsers . I signed out and back

问题 I have a route that listens to a particular route id. /** * Chat app routes. */ app.get('/games/:id', gameChatController.chatRoom); Based on the route id I can determine what game the chat is about. My question is how do I use this to pass into socket.io? bin/www /* * setup socket.io, and socket-session */ var socketIO = require('socket.io'); var io = socketIO(server); var SessionSocket = require('session.socket.io'); var sessionSockets = new SessionSocket(io, app.sessionStore, app

问题 When this code hits the redirect line it throws the 'Can't set headers after they are sent error' and doesn't redirect. I'm guilty of not fully understanding headers and how express works with them. This link about this error is confusing me a bit, probably because I don't have a basic enough understanding of what's going on. Also, I know this is a bit of a naive approach to authenticating, but I'm just trying to get basic things to work. app.post('/api/login', function(req, res) { if (req

问题 I want to test if the middleware in app.js is called. Although I mock the module work.js , it still runs the original code. app.js const work = require('./work') const express = require('require') const app = express() .use(work) .use(...) .get(...) module.exports = app work.js function work(req, res, next){...} module.exports = work app-test.js const supertest = require('supertest') const app = require('../app') test('test middleware in app.js', async(done) => { jest.mock('../work', () =>

问题 I've been at this problem for a while and I cannot make the existing solutions work for me. I have a Node.js API written in Express.js. I have been writing tests for the API using Mocha, Chai, and Supertest. These test are mostly integration tests. One test may look like: it('should fail to register a new user without the proper information', function(done) { api.post('/user') .send({}) .expect(400) .expect('Content-Type', /json/) .end(function(err, res) { should.exist(res.body); should.exist

问题 I'm creating the simple api project in nodejs. For that i have installed mySql workbench with version 8.0.11.
