Question

我遇到使用最新版Express，Node.js处理会话的问题。我的要求是将用户的电子邮件ID存储在/ login路由中，并且需要考虑该电子邮件ID 像/ home这样的所有路线。但是电子邮件ID不会使用我当前的代码在/ home路径中打印。非常感谢你的帮助。

我的演示代码在这里

var express = require('express');
var app = express();
var cookieParser = require('cookie-parser');
var session = require('express-session');
var RedisStore = require('connect-redis')(session);
app.set('port',process.env.PORT || 3000);
app.use(cookieParser());
app.use(session({
    resave: false,
    saveUninitialized: false,
    store: new RedisStore({
      host: 'localhost',
      port: 6379
    }),
    secret: 'some string/hash secret'
}));


var counter=0;
app.get('/login', function(request, response){
  //adding some value to request.session
  request.session.email = 'jak@amt.in';
  console.log('sessionID', request.sessionID)
  response.send('email: '+request.session.email);

});
app.get('/home', function (request, response) {
  console.log('home login', request.session.email); // Email not priting here 
  console.log('sessionID - home', request.sessionID); // Session ID is showing 
  response.send('home');
});

if (!module.parent) {
    console.info('Listening ', process.env.PORT || 5000);
    app.listen(process.env.PORT || 5000);
}
module.exports = app;

我收到以下错误

"ReplyError: ERR wrong number of arguments for 'set' command
    at parseError (/home/dibeesh/obpnode6/testproject/node_modules/redis/node_modules/redis-parser/lib/parser.js:161:12)
