express

问题 I just brought up this issue with Express and I am interested in what StackOverflow thinks about it: https://github.com/strongloop/express/issues/2831 my question is why Express opts to disallow the developer from passing data directly between middleware functions and basically forces you to assign temporary data to the request object in what I have always considered to be a quite awkward assignment. to be more specific: passing data between middleware functions usually involves doing this

问题 I want to know if its possible that multiple functions can consume single stream in node.js. If yes How can this done? Is it possible to pipe to multiple destinations? I want to use the stream in two different functions which are parallel. I am doing the parallel flow using the async module. So will it possible to say issue the pipe() statement inside each of these functions? Thanks in advance. 回答1: Yes , it's possible, easy and common. The following is a piped data stream from a single

问题 I cant seem to find a way to set a secure cookie in expressjs framework. Is there an option to do this somewhere? 回答1: Based on the documentation, try this: res.cookie('rememberme', 'yes', { expires: new Date(Date.now() + 900000), httpOnly: true, secure: true }); Using res.cookie(name, val[, options]) sets the given cookie name to val , with options httpOnly , secure , expires , etc. The path option defaults to the app’s basepath setting, which is typically "/" . See the docs for res.cookie

问题 I've been making node.js website using angular template. But I can't create data on DB(Mongo). Here are code. node routing. var Property = mongoose.model('Property'); var jwt = require('express-jwt'); var auth = jwt({ secret: 'SECRET', userProperty: 'payload' }); var Schema = mongoose.Schema; var ObjectId = Schema.ObjectId; //Have also tried Schema.Types.ObjectId, mongoose.ObjectId // Property Routing Management router.post('/property', auth, function(req, res, next) { var property = new

问题 I have been wondering why adding a callback to the mongoose findOneAndUpdate function results in saving the data twice to the DB? public async addPersonAsFavorite(userId: string, friendId: string) { if (!await this.isPersonAlreadyFriend(userId, friendId)) { const friendList = FriendsList.findOneAndUpdate( { _id: userId }, { $push: { friendsList: friendId } }, { upsert: true, new: true }, (err, data) => { if (err) console.error(err); return data; } ); return friendList; }} public async

问题 In the front end, I use jQuery to send a GET request like this: $.get('/api', {foo:123, bar:'123'), callback); according to jQuery doc, the 2nd parameter is a plain object that will be converted into query string of the GET request. In my node express back end, I use body-parser like this: const bodyParser = require("body-parser"); app.use(bodyParser.urlencoded({ extended: true })); app.get('/api', (req, res) => { console.log(req.query) // req.query should be the {foo:123, bar:'123'} I sent }

问题 I know by the console that the route is pointing it to the correct Id number, but it's throwing a 404 and I'm not sure where the connection is going bad. "PrizesById" is essentially a duplicate of another route holding data called "Prizes." I wasn't sure if recreating two separate places to pull identical data would be a way to do this, as I couldn't find a way to do it for "prizes". Both are required the same way This is a sample of my prizesbyid.js (in routes) const express = require(
