Nodejs:Express + RedisStore,req.session undefined

Question

我之前已经这样做了......这次我没有按照我做错的事情,但是我已经苦苦挣扎了几个小时,现在认为自己被精神上阻挡了.相应的代码:

app.use(express.bodyParser());
app.use(i18next.handle);
app.use(express.methodOverride());
app.use(express.static(__dirname + '/public'));
app.set('views', __dirname + '/views');
app.set('view engine', 'swig');
app.set('view cache', false);
var session_store = new RedisStore({ client : redis_client});
app.use(express.errorHandler({ dumpExceptions : true, showStack : true}));
app.use(express.cookieParser());
app.use(express.session({ store : session_store, secret : SESSION_SECRET, key : "sid" }));
app.use(app.router);

然后在处理请求时,这只是一个例子:

app.get('/session_test', function (req, res, next) {
  console.log(req.session); //undefined
});

连接到redis工作得很好.没有显示错误.然后,当尝试从请求访问它时,req.session未定义.浏览器正在发送正确的sid.

我不是请求期间发生的确切流的专家,但在调试之后,似乎路由器在会话中间件之前被调用.

提前感谢任何和所有可能的帮助.我会提供任何我能提供的代码,我不确定你的帮助是什么.

这是更多的代码.server.js

  //Dependency modules
var express = require('express'),
  app = express.createServer(),
  //Application dependency modules
  settings = require('./settings'), //app settings
  routes = require('./routes'), //http routes
  rtroutes = require('./rtroutes'); //real time communication routes (io)

var io = require('socket.io').listen(app);
var appWithSettings = settings.setup(io, app);

routes.settings.setup(appWithSettings);
rtroutes.settings.setup(io, appWithSettings);

在调用routes.settings.setup之前,不会添加任何路由.设置(这是全局设置)是一个非常大的文件.这就是所有配置完成的地方.在调用settings.setup方法之前,不会添加设置.这是文件的剪切:

//Dependency modules
var express = require('express'),
  redis = require('redis'),
//Important configuration values
var SESSION_SECRET = 'some secret thing which doesnt belong to stackoverflow!',
    insert_other_variables_here = "lalala";

//Computed general objects

var RedisStore = require('connect-redis')(express),
  redis_client = redis.createClient(REDIS_PORT, REDIS_HOST);

exports.setup = function (io, app) {
  app.configure(function () {
    app.use(express.bodyParser());
    app.use(i18next.handle);
    app.use(express.methodOverride());
    app.use(express.static(__dirname + '/public'));
    app.set('views', __dirname + '/views');
    app.set('view engine', 'swig');
    app.set('view cache', false);
    var session_store = new RedisStore({ client : redis_client});
    app.use(express.errorHandler({ dumpExceptions : true, showStack : true}));
    app.use(express.cookieParser());
    console.log("ABOUT TO ADD SESSION STORE MIDDLEWARE");
    app.use(express.session({ store : session_store, secret : SESSION_SECRET, key : "sid" }));
    console.log("AND NOW ADDED THE SESSION STORE MIDDLEWARE");
    app.use(app.router);
  });

  app.configure('development', function () {
     //some things in here, but nothing that affects app. I have commented this
     //for debugging and it changed nothing
  });

  app.configure('production', function () {
    //mostly configuration for io and some caching layers, as well as servers info
    app.use(express.errorHandler());
    app.use(express.logger({ stream : logFile }));
  });
  app.listen(WEB_PORT);
  return {
    app : app,
    //some other stuff that isn't relevant
  }
}

我有25个路由分成4个不同的文件(不知怎的,我直到现在才需要会话,因为我推迟了一些部分,所需的一切都是用Mongoose完成的).这是一个如何完成它的例子(假名):

路线/ index.js

export.settings = require("./settings");

路线/ settings.js

exports.setup = function (app_settings) {
  require("./route1")(app_settings);
  require("./route2")(app_settings);
  require("./route3")(app_settings);
};

这是一个剥离的"route1"文件("routes/route1.js"):

module.exports = function (app_settings) {
  var app = app_settings.app;
  console.log("ABOUT TO ADD ROUTES")
  app.get("/signin", function (req, res, next) {
    console.log(req.session); //this will be undefined
  });
  app.get("/register", function (req, res, next) {
  });
  app.get('/language', function (req, res, next) {
  });
  app.post('/settings', function (req, res, next) {
  });
  console.log("ADDED ROUTES NOW!")
}

无论何时定义路由,路由器都会自动插入到当时中间件堆栈中的任何内容(后续尝试有意插入它将被忽略).在设置会话处理程序之前,您确定没有定义任何路由吗？
