express

问题 I'd like some help as I'm new to Node.js and express. I have the following code which I'm testing on Postman const Joi = require('@hapi/joi'); const bodyParser = require('body-parser'); // Load the express framework const express = require('express'); const app = express(); app.use(express.json()); app.use(bodyParser.json()); app.use(express.urlencoded({ extended: true })); // temp array const courses = [ {id: 1, title: 'Learning Node.js'}, {id: 2, title: 'How to become a full stack dev'},

问题 I'm new to mongoose/mongo and express so I'm not quiet sure how to go about this. So basically I'm trying to use checkboxes to sort of "filter" results in my database. Here's an example of something in my db: { "location" : "PHARMACY", "region" : "SOCAL", "system" : "WITS", "contact" : "SMITH", "membership" : "TIER1" } So far I've only figured out how to hard code it like this, where I do Environment.find({region: "SOCAL"}) and it spits out all the db entries that contain SOCAL as a region:

问题 I have an express app that uses Facebook authentication via Passport.js and the passport-facebook strategy. I have followed the documentation on how to handle authentication. It all works fine... until Facebook tries to report an error via the callback Url. In this case, I get an uncaught FacebookAuthorizationError exception, and the failureRedirect is not called. End users see an "Internal Server Error" as a result of the un-caught exception and I am in non-compliance with Facebook

问题 I'm currently on project that needs to use an httpOnly cookie. The project requires a direct call to the API. Let's say it's xxx.com/vx/auth/login that authenticates user login attempt. That endpoint will give response and also set-cookie to the client. Something like this: Set-Cookie:token
