javascript - 在带有Express和mysql的nodejs中未定义 session

我正在使用express，node.js和mysql，这是我的代码

var bodyParser = require("body-parser");
var bcrypt = require('bcrypt');
var urlEncodedParser = bodyParser.urlencoded({extended: false});
var session = require('client-sessions');
var express = require('express');
var app = express();

//mysql

var mysql = require("mysql");


app.post('/login', function(request, response){
    var body = request.body;
    connection.query("select * from registeration where username='"+body.username+"' and password='"+body.pwd+"'",function(err, rows){
        if(err) {
            console.log("username and password are not matched.");
            response.end();
        } else {
            console.log("done");
            response.send(rows);
            request.usersession.user = user;
            response.redirect(301, '/account');
        }
    });

});

app.get('/account', function (request, response){
    if(request.usersession && request.usersession.user) {
        response.Send({requ: request.usersession.user});

        response.write('user detail ' + request.usersession.user[0]['username']);
        console.log('account in');
    }else{
        console.log('session error');
        response.end();
    }
});

最佳答案

在尚未通过身份验证时，将重定向添加到/ login：

app.get('/account', function (request, response){
    if(request.usersession && request.usersession.user) {
        response.Send({requ: request.usersession.user});

        response.write('user detail ' + request.usersession.user[0]['username']);
        console.log('account in');
    }else{
        console.log('session error');

        // here you should redirect to login:
        response.redirect('/login');
        response.end();
    }
});
