我創建了一個 Node js 應用程式，我正在使用創建會話
app.use(session({
resave: true ,
rolling: true,
secret: '2853554111' ,
genid: function(req) { return uuid(); },
saveUninitialized: true
}));
這就是我在會話中保存資料的方式。
req.session.user=req.body.username;
但是一段時間后，我在會話中獲得了未定義的用戶值，這種情況非常頻繁，不確定代碼有什么問題。
這就是我的 app.js 的樣子
var createError = require('http-errors');
var express = require('express');
var path = require('path');
var cookieParser = require('cookie-parser');
var logger = require('morgan');
var session = require('express-session');
var indexRouter = require('./routes/index');
var usersRouter = require('./routes/users');
var bodyParser = require('body-parser');
var uuid = require("uuidv4");
var app = express();
var login = require('./routes/login-admin');
var adminHome = require('./routes/adminHome');
var pmLogin = require('./routes/pmLogin');
var pmHome = require('./routes/pmHome');
var confirmEmail = require('./routes/confirmEmail');
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
app.use(express.static('public'));
app.use(logger('dev'));
//app.use(express.json());
app.use(express.json({limit: '5120mb'}));
//app.use(bodyParser.json())
app.use(bodyParser.json({ limit: '5120mb' }))
app.use(express.urlencoded({limit: '5120mb', extended: false }));
// view engine setup
app.use(session({
resave: true ,
rolling: true,
secret: '2853554111' ,
genid: function(req) { return uuid(); },
saveUninitialized: true
}));
app.use('/', indexRouter);
//app.use('/', login);
app.use('/users', usersRouter);
app.use('/login-admin', login);
app.use('/adminHome', adminHome);
app.use('/login', Login);
app.use('/Home', Home);
app.use('/confirmEmail', confirmEmail);
uj5u.com熱心網友回復：
您可以使用store屬性express-session將會話保存在資料庫中。此鏈接中給出了多個示例。下面是連接node js到Mysql的片段
const MySQLStore = require('express-mysql-session')(session);
const options = {
host: "xx.xx.xx.xx", // setting connection options
user: 'node',
password: "xxxxxxxx",
database: 'xxxxx',
socketPath: 'xxxxx' //required only if using GAE
};
const sessionStore = new MySQLStore(options);
app.use(session({
resave: true ,
rolling: true,
secret: 'xxxxxx' ,
saveUninitialized: true,
cookie: { maxAge: 86400000 },
store: sessionStore,
}));
你很高興。
