我尝试使用Express passport-local，这是我的配置：
App.js
var app = express();
app.use(require('morgan')('combined'));
app.use(require('cookie-parser')());
app.use(require('body-parser').urlencoded({ extended: true }));
app.use(require('express-session')({ secret: 'keyboard cat', resave: false, saveUninitialized: false }));
app.use(passport.initialize());
app.use(passport.session());
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(session({
secret: 'my super secret',
resave: false,
saveUninitialized: true
}));
index.js
var MongoClient = require('mongodb').MongoClient, assert = require('assert');
var session = require('express-session');
var passport = require('passport');
var localPassport = require('passport-local').Strategy;
var url = 'mongodb://localhost:27017/mydb';
var router = express.Router();
passport.use(new localPassport(
function(username, password, cb) {
console.log(">>>To evaluate : " + username);
console.log(">>>To evaluate : " + password);
MongoClient.connect(url, function(err, db) {
db.collection('users').find({email: username, password: password, verified: true }, {_id=0, email=1, name = 1}).toArray(function(err, results){
console.log("Fetching results!!!!");
console.log(results);
if(results.length >= 1){
console.log("<<<returning true");
return cb(null, results[0]);
}else{
console.log("<<<returning 00000");
return cb(null, false);
}
});
});
}
));
passport.serializeUser(function(user, cb) {
cb(null, user.id);
});
passport.deserializeUser(function(id, cb) {
db.users.findById(id, function (err, user) {
if (err) { return cb(err); }
cb(null, user);
});
});
router.get('/invites', function(req, res, next) {
require('connect-ensure-login').ensureLoggedIn(),
console.log("~~~~~~ ~ ~~~~~ ~~~~~~~~Fetched!");
console.log(req);
res.render('invites.html');
});
router.post('/login', function(req, res, next) {
//res.render('invites.html');
//var auth = passport.authenticate('local', { failureRedirect: '/login' });
passport.authenticate('local')(req, res, function () {
console.log(">>>Auth: ");
console.log(req);
res.redirect('/invites');
});
});
好的，让我解释一下代码：
代码执行没有问题和方法：
正确调用passport.use(new localPassport（我调试了变量），结果没问题
console.log("<<<returning true");
return cb(null, results[0]);
这些行显示在终端（而不是其他），然后我假设方法没问题。
但是，当我尝试使用：req.user时，变量为undefined。
我不确定为什么用户会话没有存储在请求中。
一些想法？

好吧我终于解决了，这是一个非常质朴的代码，但作为例子。
var express = require('express');
var passport = require('passport');
var Strategy = require('passport-local').Strategy;
var nodemailer = require('nodemailer');
const uuidV1 = require('uuid/v1');
var MongoClient = require('mongodb').MongoClient, assert = require('assert');
var moment = require('moment');
var session = require('express-session');
var passport = require('passport');
var localPassport = require('passport-local').Strategy;
var path = require('path');
var url = 'mongodb://localhost:27017/viraldb';
// Configure the local strategy for use by Passport.
//
// The local strategy require a `verify` function which receives the credentials
// (`username` and `password`) submitted by the user. The function must verify
// that the password is correct and then invoke `cb` with a user object, which
// will be set at `req.user` in route handlers after authentication.
passport.use(new Strategy(
function(username, password, cb) {
username = username.toLowerCase();
MongoClient.connect(url, function(err, db) {
db.collection('users').find({email: username, password: password, verified: true }, {_id:0, email: 1, name:1, id: 1}).toArray(function(err, results){
if(results.length >= 1){
return cb(null, results[0]);
}else {
return cb(null, false);
}
});
});
}));
// Configure Passport authenticated session persistence.
//
// In order to restore authentication state across HTTP requests, Passport needs
// to serialize users into and deserialize users out of the session. The
// typical implementation of this is as simple as supplying the user ID when
// serializing, and querying the user record by ID from the database when
// deserializing.
passport.serializeUser(function(user, cb) {
cb(null, user.id);
});
passport.deserializeUser(function(id, cb) {
MongoClient.connect(url, function(err, db) {
db.collection('users').find({id: id, verified: true }, {_id:0, email: 1, name:1, id: 1}).toArray(function(err, results){
