问题 Update: The below error was fixed by a commit. I've marked the first answer as 'correct', though the commit was brought to my attention in one of its comments I was hoping to utilize the custom callback to handle both successes and failures for logins in Passport's authenticate local strategy, but it looks like it's only called on success. Here is a snippet of what I'm talking about: passport.use(new LocalStrategy( {usernameField: 'email', passwordField: 'password'}, function(email, password,

问题 I don't understand what everyauth promises are. I see that I need to return a promise object or user, but what is an everyauth promise? 回答1: It's useful when you have a function that performs authentication, but which does so asynchronously. You can't directly return user information from the function (because you have to wait for the callback to fire), so instead you return a promise . This is a special object that acts as a "placeholder" for what will eventually be filled with user

问题 I began learning Node.js today and I'm a little stuck. Following this example, I get the following error when I try executing the js file: Warning: express.createServer() is deprecated, express applications no longer inherit from http.Server, please use: var express = require("express"); var app = express(); Socket.IO's `listen()` method expects an `http.Server` instance as its first parameter. Are you migrating from Express 2.x to 3.x? If so, check out the "Socket.IO compatibility" section

问题 I have User schema which has a username field. I would like this field to be case sensitive, so that users may register names such as BobDylan . However, I need my schema to validate new entries to check there are no duplicates, incase sensitive, such as bobdylan . My research has taught me that I should create an additional field in the schema for storing a lower case / upper case version, so that I can easily check if it is unique. My question is, how would I achieve this with the Mongoose

问题 I am using express.js as a webserver and would like an easy way to separate all the "app.get" and "app.post" functions to separate files. For example, if I would like to specify get and post functions for a login page, I would like to have a login.js file in a routes folder that is dynamically loaded (will automatically add all of the files without having to specify each one) when I run node app.js I have tried this this solution!, but it isn't working for me. 回答1: app.js var express=require(

问题 I am serving up my web application using NodeJS server (ExpressJS) currently. One of the new requirements is for the users to be able to upload large videos (potentially in gigs) to the server. They will later then be able to download them again. Could I achieve this with the current stack? I came across tutorials using Multer JS with "multipart/form-data" specified by the front-end. If I use this, would my Express be able to serve up other HTTP requests while writing a giant single video

问题 I have a websocket running on node.js 4.0 on server 10.0.4.18 at port 8020. I implemented my websocket using socket.io v1.3, express, and express-session. Project Definition I need to be able to create a session in socket.io for every user that connects to it from a PHP application. After the user send the first HTTP request, I will authenticate them using a token that will be passed from PHP to socket.io along with the HTTP request. After the user is authenticated, I need to save some
