Question

我无法将会话传递到下一条路由。我存储了会话并记录了该会话，它在那里，但是当我将其重定向到下一个视图时，它消失了。

这是我的app.js

// require modules
const createError = require('http-errors');
const express = require('express');
const cookieSession = require('cookie-session');
const flash = require('express-flash');
const path = require('path');
const cookieParser = require('cookie-parser');
const logger = require('morgan');
const bodyParser = require('body-parser');
const appRoot = require('app-root-path');
const session = require('express-session');



// require routers
const indexRouter = require('./routes/index');
const facturasRouter = require('./routes/facturas');
const dashboardRouter = require('./routes/dashboard');
const rendicionesRouter = require('./routes/rendiciones');
const perfilRouter = require('./routes/perfil');
const loginRouter = require('./routes/login');
const logoutRouter = require('./routes/logout');
const registerRouter = require('./routes/register');
const usuariosRouter = require('./routes/usuarios');
const tipocomprobanteRouter = require('./routes/tipocomprobante');
const tipogastoRouter = require('./routes/tipogasto');
const monedaRouter = require('./routes/moneda');

const app = express();

// set global variable root path
app.locals.rootPath = 'http://localhost:3000/';

// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'pug');

app.use(logger('dev'));
app.use(express.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json()); // parse form data client
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public'))); // configure express to use public folder


app.use(session({ secret: 'krunal', resave: false, saveUninitialized: true, }));


// use express-flash 
app.use(flash());

app.use('/:pageCalled',function(req, res, next){

  if(req.params.pageCalled !== 'login' && !req.session.usuario){
    console.log('Session usuario '+req.session.usuario);
    res.redirect('/login');
  } else {
    next();
  }
});

// routes
app.use('/', indexRouter);
app.use('/facturas', facturasRouter);
app.use('/dashboard', dashboardRouter);
app.use('/rendiciones', rendicionesRouter);
app.use('/perfil', perfilRouter);
app.use('/login', loginRouter);
app.use('/logout', logoutRouter);
app.use('/register', registerRouter);
app.use('/usuarios', usuariosRouter);
app.use('/tipocomprobante', tipocomprobanteRouter);
app.use('/tipogasto', tipogastoRouter);
app.use('/moneda', monedaRouter);


// catch 404 and forward to error handler
app.use(function(req, res, next) {
  next(createError(404));
});

// error handler
app.use(function(err, req, res, next) {
  // set locals, only providing error in development
  res.locals.message = err.message;
  res.locals.error = req.app.get('env') === 'development' ? err : {};

  // render the error page
  res.status(err.status || 500);
  res.render('error');
});


module.exports = app;

这是我的login.js

const dbConnection = require('../connection');
var express = require('express');
var router = express.Router();

router.get('/', function(req, res, next) {
    res.render('login',{
        sidenav: true
    });
});

router.post('/', function(req, res, next){
    var data = [req.body.usuario, req.body.password];
    var sql = 'SELECT * FROM users WHERE user_email = ? AND user_password = ?;';
    dbConnection.query(sql, data, function(err, result, fields){
        if(result.length){
            console.log(result[0].user_email);
            req.session.usuario = result[0].user_email;
            console.log(req.session.usuario);
        } else {
            console.log('err');
        }
    });

    res.redirect('/dashboard');
});

module.exports = router;

我添加了它，以便在调用任何路由以检查用户是否登录之前检查会话：

app.use('/:pageCalled',function(req, res, next){

  if(req.params.pageCalled !== 'login' && !req.session.usuario){
    console.log('Session usuario '+req.session.usuario);
    res.redirect('/login');
  } else {
    next();
  }
});

我尝试了不同的模块，但是我不太了解它们。我尝试过使用redis，但我想这对我来说还很复杂。我是NodeJS的新手，但除了javascript之外，我对其他一些语言也有一些了解。

感谢您的回答。
