问题 How do a make a rest call from Node.js to a server that requires a certificate for authentication? 回答1: The solution is to use a custom connection pool, for which you'll need to use a custom Agent.

问题 I have a Node URL (created using Express) that can be used to download a static image of an address. So, the calling app calls the /download url and passes multiple addresses using json, then the download service would call Google Maps and save the static image of each of these addreses on the node server (it would then send it back to the calling application, but for the purpose of this question I am only interested in saving the images in the node server). Initially, we were only interested

问题 my first question here - please go easy.

So if we're looking at the page called ie(.hbs), i18next will look in the namespace called ie(.json) for the relevant language. This makes organisation and coordination of translations easier. This is how I'm currently doing it: first I send the

问题 I'm creating rest endpoints in my nodejs application as follows: In my server.js I have the following code: var express = require('express'); var app = express(); app.use(express.json({ limit: '50mb' })); app.use(express.urlencoded({ limit: '50mb', extended: true })); app.use(require('./routes/APIRoutes')); I also tried the code below instead of using the express.json and expres.urlencoded as suggested on the potential duplicate question. var app = express(); var bodyParser = require('body

问题 I have a bunch of middleware. At the first app.use I test if the process is under duress, and if so I want it to just send the static /index.html file and redirect the user's browser to "/#" + req.url . for example: app.set("port", PORT) //etc app.use(function(req, res, next) { if (something) res.sendfile('/public/index.html', { root: __dirname + '/..' }) // also, redirect the user to '/#' + req.url else next() }); // a ton more middleware that deals with the main site app.use(express.static(
