问题 I have small thumbnails stored in a MongoDB collection. While I can extract them with a .findOne() I can not serve them back over an ExpressJS route correctly. I am not storing thumbs on disk as the heroku environment does not guarantee persisted storage. I am not using GridFS as these are thumbs < 16MB. Inserting a a new document into the collection goes something like this: MongoClient.connect(url, function(err, db){ var newImg = fs.readFileSync(req.file.path); var encImg = newImg.toString(

问题 So I've been trying to work this out for some time now and I'm missing something here. I'm trying to determine the best practice for setting up routes in Express. I'd like to separate the different routes I have setup by file. I'm trying to use the Express Router module, but I can't get it to work. Here is my main server file: var express = require('express'); var handlebars = require( 'express-handlebars' ); var path = require('path'); var favicon = require('serve-favicon'); var logger =

问题 I'm running into a small issue with something I thought was possible. I want to have two express routes, one GET route /post-data and one POST route /post-recieve . The code would look something like this: app.get('/post-data', (req, res, next) => { //set url to '/post-recieve' and set body / headers }) app.post('/post-recieve', (req, res, next) => { return res.json(res.body) }) Now, when you visit /post-data you should be instantly redirected to /post-recieve except if you look in the

This is how I'm creating the token: var token = jwt.sign({ id: id, expiresIn: '2m' }, 'mysecretkey' ); This is how my middlware looks like: var token = req.headers['authorization'] var idToken =
