我有一个应用程序使用 passport.js 通过 facebook 登录用户，并且正在尝试使用 express-mysql-session 来保持他们的登录状态。如果我不包含 express-mysql-session 代码，则 Passport serializeUser 和 deserializeUser 函数会很好......但是当我取消注释尝试使用 express-mysql-session 存储 session 的代码时，deserializeUser 函数不会'不会被击中，并且用户永远不会正确登录。

server.js 文件

var express      = require('express');
var mysql        = require('mysql');
var passport     = require('passport');
var session      = require('express-session');
var MySQLStore   = require('express-mysql-session')(session);

if (typeof process.env.OPENSHIFT_MYSQL_DB_HOST === "undefined"){
    var options = {
        host     : 'localhost',
        port     : '3307',
        user     : 'user',
        password : 'password',
        database : 'database',
        socketpath: '/var/run/mysqld/mysqld.sock'
    }
} else { 
    var options = {
        host     : process.env.OPENSHIFT_MYSQL_DB_HOST,
        port     : process.env.OPENSHIFT_MYSQL_DB_PORT,
        user     : process.env.OPENSHIFT_MYSQL_DB_USERNAME,
        password : process.env.OPENSHIFT_MYSQL_DB_PASSWORD,
        database : process.env.OPENSHIFT_APP_NAME,
        socket   : process.env.OPENSHIFT_MYSQL_DB_SOCKET
    }
};    

var connection = mysql.createConnection(options);

var sessionStore = new MySQLStore({
    checkExpirationInterval: 900000,// How frequently expired sessions will be cleared; milliseconds.
    expiration: 86400000,// The maximum age of a valid session; milliseconds.
    createDatabaseTable: false,// Whether or not to create the sessions database table, if one does not already exist.
    connectionLimit: 1,
    schema: {
        tableName: 'LoginRequests',
        columnNames: {
            session_id: 'loginID',
            expires: 'expires',
            data:'data'
        }
    }
}, connection);

 self.initializeServer = function() {
        self.app = module.exports = express();
        self.app.configure(function() {
            self.app.set('views', __dirname + '/public');
            self.app.set('view engine', 'html');
            self.app.engine('html', require('hogan-express'));
            self.app.enable('view cache');
            self.app.use(express.favicon());
            self.app.use(express.logger('dev'));
            self.app.use(express.bodyParser());
            self.app.use(express.methodOverride());
            self.app.use(express.cookieParser('secret'));
            self.app.use(session({
                key: 'session_cookie_name',
                secret: 'secret',
                cookie: {maxAge: 3600000, secure:false},
                store: sessionStore,
                resave: false,
                saveUninitialized: false
            }));
            // required for passport
            self.app.use(passport.initialize());
            self.app.use(passport.session()); // persistent login sessions
            self.app.use(express.static(path.join(__dirname, 'public')));
            self.app.use('/public',express.static(__dirname, '/public'));
            self.app.use(self.app.router);
            //self.app.use(require('stylus').middleware(__dirname + '/public'));


        });

    require('./routes/site.js');  
    require('./config/passport.js')(passport); // pass passport for configuration 

    }

所以，如果我在上面的 session 对象中注释掉“存储”选项， Passport 功能就会受到影响。如果我不注释此行，则不会命中 deserializeUser 函数。

Passport 功能

passport.serializeUser(function(user, done) {
        console.log('you have been serialized!');
            done(null, user.id);
    });


    // used to deserialize the user
    passport.deserializeUser(function(id, done) {
        console.log('you have been deserialized!');
        connection.query("SELECT * FROM Users WHERE id = "+id,function(err,rows){
            done(err, rows[0]);
        });
    });

编辑

Mor Paz 建议我在使用调试模块运行服务器时包含一些日志。以下是用户序列化之前和之后的日志。用户应该在这个附近的某个时候反序列化，但永远不会。

最佳答案

无法复制该问题，因此我准备了一个工作示例。 [Github repo.]

它是为 Openshift 设计的，因为我看到了它的 环境 变量的用法(它可以轻松适应其他用例)。

我对原来的概念做了一些修改:

1. 替换了旧的、已弃用(快速)的捆绑中间件用法。
2. 使用 Class 代替 self = this 概念
3. 使用 Github 而不是 Facebook 进行用户登录...
4. 包含一些基本功能以将新用户包含到数据库中
5. 缺少一些原始模块(可以轻松包含)

我希望它可以作为一个有用的起点。
