如何使用connect-sqlite3與express和websocket共享會話？

Question

我需要使用connect-sqlite3在express-session（v4）GET請求和WebSockets on（'connection'）上共享會話。

以下不帶sqlite3的基本設置（來自Azmisov在ExpressJS和Websocket和會話共享中的回答）可以工作：

global.app = express();
var sessionParser = require('express-session')({
    secret:"some secret",
    resave: true,
    saveUninitialized: true
});
app.use(sessionParser);

app.get('*', function (req, res) {
    req.session.working = "Yes";
});

wss.on('connection', function connection(ws, req) {
    sessionParser(req, {}, function(){
        console.log("New websocket connection: Working = " + req.session.working + ".");
    });
});

但是，當我嘗試使用connect-sqlite3實現此功能時：

var sessionParser = require('express-session');
var SQLiteStore = require('connect-sqlite3')(sessionParser);
app.use(sessionParser({
    store: new SQLiteStore({dir:configuration.data_dir, db:'sessions.s3db', table:'sessions'}),
    secret: 'some secret',
    resave: false,
    saveUninitialized: true,
    cookie: {
        maxAge: configuration.session_cookie_maxage_ms,
        name: 'shadowlands'
    },
}));

app.get('*', function (req, res) {
    req.session.working = "Yes";
});

wss.on('connection', function connection(ws, req) {
    sessionParser(req, {}, function(){
        console.log("New websocket connection: Working = " + req.session.working + ".");
    });
});

在sessionParser（req，{}，function（）{...）的wss on（'connection'）中，我得到：

express-session deprecated undefined resave option; provide resave option; provide resave option.
express-session deprecated undefined saveUninitialized option; provide saveUninitialized option; provide saveUninitialized option.
express-session deprecated req.secret; provide secret option.

如果我更改為：仍然會發生此錯誤：

sessionParser(req, {secret: 'some secret', resave: false, saveUninitialized: true}, function(){

如果我取出“ req”，錯誤消失了：

sessionParser({secret: 'some secret', resave: false, saveUninitialized: true}, function(){

但是，然后不會調用sessionParser函數，並且控制台中不會顯示req.session.working。

該會話實際上確實已保存到sqlite3數據庫。

任何幫助，不勝感激，謝謝！ 埃里克·T。

Answer 1

我設法在websocket on（'connection'）上使用cookie解析器和cookie來修復它。

請注意，我必須在app.use（）外部聲明MySessionStore，以便可以對其執行get（）。

var sessionParser = require('express-session');
var SQLiteStore = require('connect-sqlite3')(sessionParser);
var MySessionStore = new SQLiteStore({dir:configuration.data_dir, db:'sessions.s3db', table:'sessions'});
var cookieParser = require('cookie-parser');
var cookie = require('cookie');
app.use(cookieParser())
var sessionParser = require('express-session');
app.use(sessionParser({
    resave: true,
    saveUninitialized: true,
    secret: "some secret",
    store: MySessionStore,
    cookie: { maxAge: 7 * 24 * 60 * 60 * 1000 } // 1 week
}));

// ============

app.get('*', function (req, res) {
    req.session.working = "Yes";
});

// ============

wss.on('connection', function connection(ws, req) {

    var got_cookie = false;

    var cookies = cookie.parse(req.headers.cookie);
    var sessionID = cookieParser.signedCookie(cookies['connect.sid'], "some secret");
    MySessionStore.get(sessionID, function(err, sess) {
        functions.write_log("session", "WSS: New websocket connection: " + "Working = '" + sess.working + "'.");
        got_cookie = true;
    });

    // Optional, if you need a synchronous return from the function. 
    require('deasync').loopWhile(function(){return !got_cookie;});

});
