我正在尝试使用快速会话将会话存储在Redis中,但它似乎并不想保存。当我恢复到默认会话存储时,它可以完美地工作。 Redis守护程序托管在具有默认配置的Vagrant VM上,应用程序可以连接到它,但它不想将会话保存到它。
这是我的代码:
var express = require('express');
var glob = require('glob');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var compress = require('compression');
var methodOverride = require('method-override');
var session = require('express-session');
var passport = require('passport');
var redis = require('redis');
var RedisStore = require('connect-redis')(session);
var auth = require('./passport');
var flash = require('connect-flash');
module.exports = function(app, config) {
app.set('views', config.root + '/app/views');
app.set('view engine', 'jade');
// app.use(favicon(config.root + '/public/img/favicon.ico'));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
extended: true
}));
app.use(cookieParser());
app.use(session({
store: new RedisStore({
host: config.redis.host,
port: config.redis.port
}),
secret: config.secret,
saveUninitialized: true,
resave: false
}));
/*app.use(session({
secret: config.secret,
saveUninitialized: true,
resave: true
}));*/
app.use(passport.initialize());
app.use(passport.session());
app.use(flash());
app.use(compress());
app.use(express.static(config.root + '/public'));
app.use(methodOverride());
var controllers = glob.sync(config.root + '/app/controllers/*.js');
controllers.forEach(function (controller) {
require(controller)(app);
});
app.use(function (req, res, next) {
var err = new Error('Not Found');
err.status = 404;
next(err);
});
if(app.get('env') === 'development'){
app.use(function (err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: err,
title: 'error'
});
});
}
app.use(function (err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: {},
title: 'error'
});
});
};
正如你所看到的,我得到了一个注释掉的默认值,如果我删除那些注释并注释掉redis商店,它就可以正常工作了。任何线索为什么会发生这种情况?我没有收到任何错误。

您可能有一些连接错误,但connect-redis
不会将它们输出到控制台(请参阅connect-redis source code)。要查看它们,您可以创建一个单独的模块来创建客户端实例并将其传递给RedisStore
构造函数:
// redisClient.js
var redis = require('redis');
var redisClient = redis.createClient('localhost', 6379); // replace with your config
redisClient.on('error', function(err) {
console.log('Redis error: ' + err);
});
module.exports = redisClient;
Redis客户端还会发出其他可能有助于调试的事件 - 请参阅node-redis docs
// your code
var redisClient = require('./redisClient.js`);
(...)
app.use(session({
store: new RedisStore({
client: redisClient
}),
secret: config.secret,
saveUninitialized: true,
resave: false
}));
