我想访问我的护照策略在其回调中指定的消息，如下所示done(null, false, { message: 'No such user.' });：到目前为止，我发现这些消息可以通过将选项传递给函数来显示failureFlash: true，passport.authenticate()再次使用需要connect-flash安装中间件。所以我安装了模块并添加var flash = require('connect-flash);到我的源代码中，以及app.use(flash());我的 express 应用程序的配置方法中。.flash()但它仍然会因方法不可用的错误而崩溃。我错过了什么？

更多代码：

var http = require('http');
var express = require('express');
var passport = require('passport');
var googleStrategy = require('passport-google').Strategy;
var flash = require('connect-flash');

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

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

passport.use(new googleStrategy(
    { 
        returnURL: 'http://localhost:123456/auth/google/return', 
        realm: 'http://localhost:123456/' 
    },
    function(identifier, profile, done) {
        process.nextTick(function () {
            User.findOne({ ID: identifier }, function (err, user) {
                if (err) {
                    return done(err);
                }

                if (!user) {
                    return done(null, false, { message: 'no such user' });
                }

                return done(null, user);
            });
        });
    })
);

var app = express();

app.configure(function() {
    app.set('view engine', 'ejs');
    app.set('views', __dirname + '/views');
    app.use(express.logger());
    app.use(express.cookieParser());
    app.use(express.bodyParser());
    app.use(express.methodOverride());
    app.use(express.session({ secret: 'veryverysecretsecret' }));
    app.use(passport.initialize());
    app.use(passport.session());
    app.use(app.router);
    app.use(flash());
});

app.get(
    '/auth/google',
    passport.authenticate('google', { failureRedirect: '/login', failureFlash: true }),
    function (req, res) {
        res.redirect('/');
    }
);

app.get('/auth/google/return',
    passport.authenticate('google', { failureRedirect: '/login', failureFlash: true }),
    function (req, res) {
        res.redirect('/');
    }
);

http.createServer(app).listen(123456);

Passport 需要先配置闪存。

要解决您的问题，只需更改 中的顺序app.configure()，然后将护照用途移至其下方，如下所示：

app.configure(function() {
    app.set('view engine', 'ejs');
    app.set('views', __dirname + '/views');
    app.use(express.logger());
    app.use(express.cookieParser());
    app.use(express.bodyParser());
    app.use(express.methodOverride());
    app.use(express.session({ secret: 'veryverysecretsecret' }));
    app.use(flash());
    app.use(passport.initialize());
    app.use(passport.session());
    app.use(app.router);
});

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

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

passport.use(new googleStrategy(
    { 
        returnURL: 'http://localhost:123456/auth/google/return', 
        realm: 'http://localhost:123456/' 
    },
    function(identifier, profile, done) {
        process.nextTick(function () {
            User.findOne({ ID: identifier }, function (err, user) {
                if (err) {
                    return done(err);
                }

                if (!user) {
                    return done(null, false, { message: 'no such user' });
                }

                return done(null, user);
            });
        });
    })
);

很高兴它有帮助！
