问题 I'm building a web application using the MEAN stack. The site contains authentication (using passport.js) so I would like to secure our connection with SSL/TLS. For our deployment we're using nginx as a reverse proxy to the Node app running on the same AWS EC2 instance. My question is: With my setup, what is the best practice way to setup an https (SSL/TLS) connection? Should I get a certificate and set it up at the nginx layer? Should I do it in my node app directly? Is there some other

问题 I am writing custom middleware(s) to send request data(like request path, response code, request timestamp, etc) to a remote server on every request. I'm unable to figure out the ordering of my middlewares. I have created 2 middlewares, a) process_request (m1) --> this middleware just adds a timestamp to the request object to register when the request was received. b) process_response (m2) --> this middleware posts the required data to the remote server m1 function process_request(req, res,

问题 So I built a simple mern app that works fine on my local environment, but when deploying to Heroku, it serves the react app fine but 404s on the API calls. I can't seems to figure out the issue. I'm sending requests using Axios. I checked the network requests and they all look good, but still come back 404. testing in postman also returned the same error. Here's the server code... Any idea why this is failing? const express = require('express'); const path = require('path'); const Axios =

问题 When I run my Node.js express app using node command everything works fine! When using pm2 server ./bin/www` my pm2 status is something like this: And my app works in this situation.

问题 I am sending an id from a jade view to its controller (backend), the controller then queries mongodb and the result is sent to a new jade view - angular . The results & view appear but URL stays the same (previous view), thus if I F5 the current view, it reloads the previous view.

问题 Using Express, how can I determine the response has been sent / that the response has been completely written to? app.use((req,res,next) => { if(res.ended){ // } if(res.finished){ // } }); how can I tell if res.end() has been called? I am looking for a boolean I can read on res. 回答1: response.end() will set response.finished if it's been called, as per the documentation. 回答2: Use res.writableEnded (docs). res.finished is deprecated (see). 来源： https://stackoverflow.com/questions/57618325/check
