Node.js PassportJS对用户进行身份验证，但在后续请求中返回401 Unauthorized

我正在用NodeJS编写我的第一个应用程序，所以请耐心等待。我已经成功地向Active directory验证了一个用户的身份，我可以看到connect.sid cookie被设置并用于后续请求

在通过转储req对象调试应用程序时，我还可以看到用户变量已成功设置。从我阅读的文档中，这似乎是会话匹配成功的标准

但是，该请求仍然得到401授权

总结如下：

用户在发布凭据/登录后已成功通过身份验证

成功验证后，用户将重定向到“/”

“/”路径以401未经授权的响应

非常感谢您的任何想法。代码如下

const express = require('express');
var bodyParser = require('body-parser');
var session = require('express-session');
var passport = require('passport')
var ActiveDirectoryStrategy = require('passport-activedirectory')

// Setup the authentication strategy
passport.use(new ActiveDirectoryStrategy({
    integrated: false,
    ldap: {
        url: 'ldap://myad.company.com',
        baseDN: 'DC=domain,DC=company,DC=com',
        username: 'user',
        password: 'password'
    }
}, function (profile, ad, done) {
    ad.isUserMemberOf(profile._json.dn, 'Group', function (err, isMember) {
        if (err) return done(err)
        return done(null, profile)
    })
}));

passport.serializeUser(function(user, done) {
    done(null, JSON.stringify(user));
  });

passport.deserializeUser(function(user, done) {
    done(null, JSON.parse(user));
});

const app = express();

app.use(bodyParser.urlencoded({extended: true}));
app.use(session(
    { secret: "password" }
));
app.use(passport.initialize());
app.use(passport.session());

// For debugging purposes
app.use(function (req, res, next) {
    console.log(req)
    next()
})

// The login page posts a form containing user and password
app.get("/login", (req, res) => {
    res.sendFile(__dirname + '/public/index.html');
})

// Handler for the login page. Receives user and password and redirects the user to /
app.post('/login', 
    passport.authenticate('ActiveDirectory', {
            failWithError: true,
            successRedirect: "/",
            failureRedirect: "/login"
        }
    ), function(req, res) {
        res.json(req.user)
    }, function (err) {
        res.status(401).send('Not Authenticated')
    }
)

// This is where the issue happens. The page returns "Unauthorized".
// Using console.log(req) shows that the user property has been set to the req object.
// However, for some reason it still fails.
app.get('/',
    passport.authenticate('ActiveDirectory', {
            failWithError: true,
        }
    ), function(req, res) {
        res.send("test")
}, function (err) {
    res.status(401).send('Not Authenticated')
})

发现我做错了什么

.authenticate方法仅用于验证凭据，而不是验证会话

因此：

app.get('/',
    passport.authenticate('ActiveDirectory', {
            failWithError: true,
        }
    ), function(req, res) {
        res.send("test")
}, function (err) {
    res.status(401).send('Not Authenticated')
})

应成为：

app.get('/', function(req, res, next) {
    // This is verifying that the user part has been populated,
    // which means that the user has been authenticated.
    if (req.user) {
        res.send('Returning with some text');
    } else {
        // If the user property does no exist, redirect to /login
        res.redirect('/login');
    }
  });

我更改的另一件事是序列化/反序列化函数：

passport.serializeUser(function(user, done) {
    done(null, user);
  });

passport.deserializeUser(function(user, done) {
    done(null, user);
});

这将删除冗余的序列化/反序列化

这些文章确实帮助我了解了流程：

希望它能帮助别人
