使用passport-ldap时继续接收错误请求

const passport = require('passport');
const LdapStrategy = require('passport-ldapauth').Strategy;

passport.use(new LdapStrategy({
    server: {
        url: 'ldap://your-ldap-server:389',
        bindDN: 'cn=admin,dc=example,dc=com',
        bindCredentials: 'password',
        searchBase: 'dc=example,dc=com',
        searchFilter: '(uid={{username}})'
    }
}, function(user, done) {
    return done(null, user);
}));

const express = require('express');
const passport = require('passport');
const LdapStrategy = require('passport-ldapauth').Strategy;

const app = express();

passport.use(new LdapStrategy({
    server: {
        url: 'ldap://your-ldap-server:389',
        bindDN: 'cn=admin,dc=example,dc=com',

        searchFilter: '(uid={{username}})'
    }
}, function(user, done) {
    return done(null, user);
}));

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

app.post('/login', 
    passport.authenticate('ldapauth', { failureRedirect: '/login' }),
    function(req, res) {
        res.redirect('/');
    });

app.listen(3000, function() {
    console.log('App listening on port 3000!');
});
