我正在尝试使用 express-session 护照在跨域中。我接受以下链接的帮助 Sending credentials with cross-domain posts? Passport js fails to maintain session in cross-domain

**I am getting below error**

加载失败 http://localhost:5000/users/login 对…的反应飞行前请求未通过访问控制检查:的值响应中的“访问控制允许来源”头不能是当请求的凭据模式为“include”时使用通配符“*”。起源 ’ http://localhost:3000 因此不允许访问。这个由xmlhttpRequest启动的请求的凭据模式为由withCredentials属性控制。

这是我的全部代码 https://github.com/naveennsit/Cors

服务器代码 服务器,JS

var app = require('./app');
const PORT = process.env.PORT || 5000;

app.listen(PORT, () => {
    console.log(`app is running on ${PORT}`);
})

App.JS

const express = require('express');
const bodyParser = require('body-parser');
const cookieParser = require('cookie-parser');
const path = require('path');

const morgan = require('morgan');
const cors = require('cors');
const session = require('express-session');
const passport = require('passport');



const app = express();



// Middleware
app.use(bodyParser.urlencoded({extended: false}));

app.use(bodyParser.json());
app.use(morgan('dev'));
app.use(cookieParser());
app.use(cors());

app.use(cookieParser());

app.use(function(req, res, next) {
    res.header("Access-Control-Allow-Origin", "*");
    res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept, authorization");
    res.header("Access-Control-Allow-Methods", "GET,POST,DELETE,PUT,OPTIONS");
    next();
});
app.use(session({
    secret: 'secret',
    resave: false,
    domain: '.localhost:3000',
    saveUninitialized: false,
    cookie:  {
        domain: '.localhost:3000',
        maxAge: 24 * 6 * 60 * 10000
    },
}))



app.use(passport.initialize());
app.use(passport.session());

//Routes


app.use('/users', require('./routes/user.route'))


module.exports = app;

控制器JS

const passport = require('passport');


const passportConfig = require('../passport')
module.exports = {
    login: async (req, res, next) => {
        console.log(req.body);
        try {

            req.login(req.body.id, function () {
                res.json({message: "Registration successfully"});

            })
        } catch (e) {
            console.log(e)
        }

    },

}

护照号码

const passport = require('passport');
passport.serializeUser(function(id, done) {
    console.log('ddd');
//    console.log(user);
    done(null, id);
});

passport.deserializeUser(function(id, done) {
    console.log('deserializeUser');
    done(null, id);
    // db.User.findById(id, function (err, user) {
    //     done(err, user);
    // });
});

路线

const express = require('express');
const router = require('express-promise-router')();


const controller = require('../controllers/user.controller');



router.route('/login',)
    .post(controller.login)



module.exports = router;

我想在跨域中添加会话。我已经应用了CORS插件,但仍然出现同样的错误。

最简单的方法是使用node.js包 cors . 最简单的用法是:

var cors = require('cors')

var app = express();

app.use(cors());

使用时 withCredentials: true 在Ajax中,CORS需要如下配置。

app.use(cors({origin: 'http://localhost:3000', credentials: true}));

你马上就要解决了。您需要将实际允许的主机发送到 Access-Control-Allow-Origin 头值与否 *

如果你想考虑所有的起源,那么你可以包括 req.headers.origin 对于 访问控制允许来源 CORS中间件中的头值:

app.use(function(req, res, next) {
    res.header("Access-Control-Allow-Origin", req.headers.origin);
    res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept, authorization");
    res.header("Access-Control-Allow-Methods", "GET,POST,DELETE,PUT,OPTIONS");
    next();
});
