使用Passport和Express进行基本身份验证

Question

我可能漏掉了什么，但根据我找到的所有教程，这是使用express和passport+ passport-local在Node应用程序中进行基本身份验证的方法。我知道这不是最佳实践，我只是想让POC运行起来：

'use strict'

var express = require('express');
var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy

var app = express();

var users = { 'user': 'secretpass'};

passport.use(new LocalStrategy(
    function(username, password, done) {
        console.log('Username:', username, 'password:', password);
        if (!users[username] || users[username] != password) {
            console.log('Username:', username, 'password:', password);
            return done (null, false);
        }
        return done(null, {username: username});
    }
    ));

app.use(passport.initialize());


app.get('/', function (req, res) {
    res.send ('GET request to root');
});

app.post('/', function (req, res) {
    res.send ('POST request to root');
});

app.get('/unauthorized', function (req, res) {
    res.status(200).send('GET Forbidden');
});

app.post('/unauthorized', function (req, res) {
    res.status(200).send('Post Forbidden');
});

app.post('/webhook', 
    passport.authenticate('local', { successRedirect: '/', failureRedirect: '/unauthorized'}),
    function (req, res) {
        res.send ('authenticated!');
    }
);

var server = app.listen(8081, function() {
    console.log('Server listening at', server.address().address, 'on port', server.address().port);
});

奇怪的是，我在LocalStrategy构造函数中甚至没有收到那些console.log()语句，所以我猜我真的错过了什么。我尝试使用DHC和Postman发送POST请求，

• 将基本身份验证字段设置为用户名和密码，
• 使用格式为username:password@url的方法，
• 将用户名和密码作为表单数据发送

Answer 1

对于基本身份验证，您需要使用 passport-http，而不是用于通过表单数据进行身份验证的 passport-local。

请尝试以下操作：

var BasicStrategy = require('passport-http').BasicStrategy;
...
passport.use(new BasicStrategy(...));
...
app.post('/webhook', 
  passport.authenticate('basic', {
    session         : false,
    successRedirect : '/',
    failureRedirect : '/unauthorized'
  }), function (req, res) {
    // FWIW, this isn't useful because it's never reached, because Passport
    // will always issue a redirect (either to / or to /unauthorized)
    res.send ('authenticated!');
  }
);

使用passport-http模块进行基本身份验证

var express = require('express');
var passport = require('passport');
var app = express();
var BasicStrategy = require('passport-http').BasicStrategy;
passport.use(new BasicStrategy(
   function (username, password, done) {
      //perform auth here for user.
      //use done(null,false) if auth fails

      done(null, {
         user: "xyz"
      });


   }
));

app.get('/app', passport.authenticate('basic', {
   session: false
}), (req, res) => {
   console.log("Hello");

   res.send('ok');
});

app.listen(4000, (err, res) => {
   console.log(err, res);
   console.log('server is launched');
})
