express

问题 I'm trying to send the response to an express request by sending it to a ws client and wait for its response. So I need to send the res object to the client (I couldn't find another way). Here is what I did: var app = require('express')(); var http = require('http').Server(app); var io = require('socket.io')(http); app.get('/', (req, res) => { res.sendFile(__dirname + '/index.html'); }); io.on('connection', (socket) => { socket.on('res', (e) => { e.res.send(e.data) }) }) app.get('/endpoint',

问题 I would like to use express to render a file AND download a file at the same time My current code is as follows: res.attachment('filename.csv'); res.render('pages/result', { data }); However, if I do this, it only downloads the data and does not render the view What I want is to render a success page, and then send the file so that it downloads I need this to be done with 1 endpoint, because, I need to generate the file and only if it is successful, I would render the success page Am I able

问题 I'm slowly losing my mind over a very stupid issue I'm having. I have a socket.io/express app uploaded to Digital Ocean as a Docker setup. To allow https, I am using caddy as part of my Docker setup to allow for automatic https. I've been trying to connect to this setup via my domain and from my local React app that lives on localhost:3000. But I am constantly getting the following error: Access to XMLHttpRequest at 'https://mediaserver.domain.dev/socket.io/?EIO=3&transport=polling&t=N5BXNK2'

问题 In my node JS express app I have defined routes with path having regex expressions in my app.js file. i.e var tableRoute = require('./routes/tables'); app.use('/keyspaces/(regex to match param)/tables',tableRoute); Then in my routes/tables.js file I have following handler defined for this route router.get('/', function(req, res, next) { // need to access url param here }); Now clearly I cannot access my url param via req.params.xzy because here handler is defined for '/' not for '/keyspaces/

问题 I'm new to javascript, nodejs, and express, and confused of using next() . I want my code to move on to the next router with next() , but it seems to move on to the next then . My code: //validation router.post('/requests', (req, res, next) => { let {myData} = req.body basicCheck(res, cluster, myData) .then(() => { if (myCheck()) { next() return // Doesn't need to do rest of the code. Just move on to the next router.post } ... return Promise.all(somePromises) }) .then(() => { ... return

问题 I'm calling my express route (domain.com/api) from another domain (domain1.com). So I've set up Express to accept POST requests to the route /api and signing a JWT before exchanging the JWT via Axios for a Bearer access token. I cannot seem to get the Axios post request to fire. Is is possible it's a firewall thing? How can I see where the error lives? Forgive me, I'm still new to Node/Express. Here is my pertinent code: const express = require('express'); const cors = require("cors"); const

问题 I'm trying to connect an Express app to MariaDB, both running on localhost. I have the following code in an Express app: const mariadb = require('mariadb'); const pool = mariadb.createPool({ user: 'testuser', password: 'password', database: 'test', connectionLimit: 5 }); I can connect using 'testuser' from the MariaDB command line, but when Express executes the code above, I see the following in the console: SQLError: (conn=63, no: 1698, SQLState: 28000) Access denied for user 'testuser'@

问题 Goal Question looks long winded - it's not! I'm using Angular Universal to implement SSR, following this tutorial. Universal/express-engine is installed, main.js is generated in the dist/projectname/server folder, and I've created a prerender.js folder in the project root. Problem When I try npm run prerender it starts work prerendering until eventually hitting the following error: Prerendering 5 route(s) to C:\Users\odubh\Documents\Personal_Web_Projects\Hibernio.com\Hibernio0.3\hibernio\dist

问题 In my express app, I am keeping the below config: var express = require("express"); var path = require("path"); var jsonServer = require("json-server"); var app = express( ); app.use(express.static('public')); app.get("/", function( req, res ) { res.sendFile( express.static( path.join(__dirname, "/public/index.html" ) ) ); }); app.use('/api', jsonServer.router('./db.json')); app.listen( 3000 ); All this is works fine. the problem is, I am not able to add the jquery from node_modules . here is

问题 A little background - I have my NodeJS server running on port 3001 and my React application on port 3000. I've set up a proxy in my React application package.json to proxy all requests to port 3001 - "proxy": "http://localhost:3001" Now when I'm using Axios in my React application to make POST request on 'users/authentication' route on my NodeJS server, the request body is being parsed as blank on the Node server const request = { method: 'POST', url: `/users/authenticate`, headers: {
