问题 I post a form with file (enctype="multipart/form-data") to node.js (express.js framework) and just want to send this same post request like it is just to different server. what is the best approach in node.js? 回答1: remove express.bodyParser and try pipes like these: req.pipe(request('http://host/url/')).pipe(res) 回答2: You could try it with Mikeal's Request for Node.js (https://github.com/mikeal/request). It would be something like: app.post('/postproxy', function(req, res, body){ req.pipe

问题 In application which I currently develop, it's using Express. In my case I want to get response before it's been sent and modify it (for purpose of JWT). In this application, there is a dozen of endpoints and I don't want to create my own function like sendAndSign() and replace res.send() everywhere in code. I heard there is option to override/modify logic of res.send(...) method. I found something like this example of modifying, but in my case this doesn't work. Is there any other option

问题 I'd like to know how to work with connectivity to a database in MEAN stack application. In particular, when should I create a connection to a database and when should I destroy a connection to a database. Should I create and destroy a connection on every new HTTP request or should I store a once created connection and use it for any subsequent requests as long as possible. I use Mongoose as a modeling tool. Here is an example. This is my routes.js file with a route /index . A request to this

问题 My node app gives me this message "Could not connect to any servers in your MongoDB Atlas cluster. Make sure your current IP address is on your Atlas cluster's IP whitelist". I've already added my current IP address along with the 0.0.0.0 on the IP whitelist. Below is a picture of the error message and the code I've written to connect it. I'm new to node.js and mongodb. I looked through all the solutions on here but none of them were able to solve this. var express = require('express'); var
