Question

由于某种原因，会话不会在两次通话之间保存。我知道还有其他这样的问题，但他们的答案对我的问题没有帮助。

服务器代码：

var express = require('express');
var app = express();
var http = require('http').Server(app);
// var io = require('socket.io')(http);
var { db } = require("./db.js");
const cors = require('cors');
var bcrypt = require("bcrypt");
var session = require('client-sessions');

var bodyParser = require('body-parser');
app.use(bodyParser.json()); // support json encoded bodies
app.use(bodyParser.urlencoded({ extended: true })); // support encoded bodies

app.use(cors({
    origin: "http://localhost:8080",
    credentials: true
}));

var salt1 = bcrypt.genSaltSync();
var salt2 = bcrypt.genSaltSync();
var secret = bcrypt.hashSync(salt1 + salt2, 10);
app.use(session({
    // activeDuration: toTime("days", 7),
    cookieName: 'session',
    // duration: toTime("days", 7),
    secret, // set this to a long random string!,
}));

http.listen(process.argv[2] || 8081);

app.get("/", function (req, res) {
    console.log(req.session)
    let { email, firstname, lastname, id } = req.session
    req.session.username = "tester"
    if (req.session.id) {
        res.send({
            email,
            firstname,
            id,
            lastname,
            success: true
        })
    }
    else {
        res.send({
            session: req.session,
            success: false
        })
    }
})

我知道会话存在，因为我可以全部并分配它。当我再次调用/路径时，它只是不保存数据。它只显示{}

由于我使用的是ajax，我还需要显式发送凭据。

xhrFields: {
    withCredentials: true
},

mozilla的客户端会话未被保存
