passport.js passport.initialize() 中间件未使用

Question

我正在将 node 与 express + mongoose 一起使用，并尝试将 passport.js 与 restful api 一起使用。
身份验证成功后我不断收到此异常（我在浏览器上看到回调 url）：

/Users/naorye/dev/naorye/myproj/node_modules/mongoose/lib/utils.js:419
        throw err;
              ^

我读到我应该把app.use(passport.initialize()); 和app.use(passport.session()); 放在app.use(app.router); 之前，这就是我所做的。这是我注册中间件的 express.js：

var express = require('express'),
    mongoStore = require('connect-mongo')(express),
    flash = require('connect-flash'),
    helpers = require('view-helpers');

module.exports = function (app, config, passport) {
    app.set('showStackError', true);
    // should be placed before express.static
    app.use(express.compress({
        filter: function (req, res) {
            return /json|text|javascript|css/.test(res.getHeader('Content-Type'));
        },
        level: 9
    }));
    app.use(express.favicon());
    app.use(express.static(config.root + '/public'));

    app.use(express.logger('dev'));

    // set views path, template engine and default layout
    app.set('views', config.root + '/app/views');
    app.set('view engine', 'jade');

    app.configure(function () {
        // use passport session
        app.use(passport.initialize());
        app.use(passport.session());

        // dynamic helpers
        app.use(helpers(config.app.name));

        // cookieParser should be above session
        app.use(express.cookieParser());

        // bodyParser should be above methodOverride
        app.use(express.bodyParser());
        app.use(express.methodOverride());

        // express/mongo session storage
        app.use(express.session({
            secret: 'linkit',
            store: new mongoStore({
                url: config.db,
                collection : 'sessions'
            })
        }));

        // connect flash for flash messages
        app.use(flash());

        // routes should be at the last
        app.use(app.router);

        // assume "not found" in the error msgs
        // is a 404. this is somewhat silly, but
        // valid, you can do whatever you like, set
        // properties, use instanceof etc.
        app.use(function(err, req, res, next){
            // treat as 404
            if (~err.message.indexOf('not found')) {
                return next();
            }

            // log it
            console.error(err.stack);

            // error page
            res.status(500).render('500', { error: err.stack });
        });

        // assume 404 since no middleware responded
        app.use(function(req, res, next){
            res.status(404).render('404', {
                url: req.originalUrl,
                error: 'Not found'
            });
        });
    });
};

怎么了？

更新 根据@Peter Lyons，我已将配置顺序更改为以下，但我仍然遇到相同的错误：

var express = require('express'),
    mongoStore = require('connect-mongo')(express),
    flash = require('connect-flash'),
    helpers = require('view-helpers');

module.exports = function (app, config, passport) {
    app.set('showStackError', true);
    // should be placed before express.static
    app.use(express.compress({
        filter: function (req, res) {
            return /json|text|javascript|css/.test(res.getHeader('Content-Type'));
        },
        level: 9
    }));
    app.use(express.favicon());
    app.use(express.static(config.root + '/public'));

    app.use(express.logger('dev'));

    // set views path, template engine and default layout
    app.set('views', config.root + '/app/views');
    app.set('view engine', 'jade');

    app.configure(function () {

        // dynamic helpers
        app.use(helpers(config.app.name));

        // cookieParser should be above session
        app.use(express.cookieParser());

        // bodyParser should be above methodOverride
        app.use(express.bodyParser());
        app.use(express.methodOverride());

        // express/mongo session storage
        app.use(express.session({
            secret: 'linkit',
            store: new mongoStore({
                url: config.db,
                collection : 'sessions'
            })
        }));

        // connect flash for flash messages
        app.use(flash());

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

        // routes should be at the last
        app.use(app.router);

        // assume "not found" in the error msgs
        // is a 404. this is somewhat silly, but
        // valid, you can do whatever you like, set
        // properties, use instanceof etc.
        app.use(function(err, req, res, next){
            // treat as 404
            if (~err.message.indexOf('not found')) {
                return next();
            }

            // log it
            console.error(err.stack);

            // error page
            res.status(500).render('500', { error: err.stack });
        });

        // assume 404 since no middleware responded
        app.use(function(req, res, next){
            res.status(404).render('404', {
                url: req.originalUrl,
                error: 'Not found'
            });
        });
    });
};

Answer 1

按照示例来避免无序的中间件地狱，因为 express 使得它很容易进入。直接来自文档。请注意您的与此不完全匹配。

var app = express();
app.use(require('serve-static')(__dirname + '/../../public'));
app.use(require('cookie-parser')());
app.use(require('body-parser').urlencoded({ extended: true }));
app.use(require('express-session')({
  secret: 'keyboard cat',
  resave: true,
  saveUninitialized: true
}));
app.use(passport.initialize());
app.use(passport.session());

文档

1. cookie 解析器
2. 会话
3. passport.initialize
4. passport.session
5. app.router

你

1. passport.initialize
2. passport.session
3. cookie 解析器
4. 会话
5. app.router

Answer 2

在我的情况下（相同的错误消息）我完全忘记添加护照初始化：

app.configure(function () {
    ...
    app.use(passport.initialize());
    app.use(passport.session());
});

更新：仅适用于 express 版本 3，版本 4 不再支持 app.configure()

Answer 3

Peter Lyons 的回答帮助我解决了这个问题，但我以不同的方式解决了它。

app.use(
  cookieSession({
    maxAge: 30 * 24 * 60 * 60 * 1000,
    keys: [keys.cookieKey],
  }),
);
app.use(passport.initialize());
app.use(passport.session());

查看我的GitHub repo 了解整个代码，而不仅仅是这里的代码 sn-p。

Answer 4

在我的情况下，错误是因为我试图承诺 req.login 而不将 this 绑定到 req，所以当调用该函数时它找不到 passport 设置。 如果您使用的是 Node v8，解决方案是先绑定 req.login.bind(req)，然后再将其传递给 promisify。

Answer 5

对我有帮助的还有将 routes 放在 cookies 配置之后：

// init Cookies:
app.use(
    cookieSession({
        maxAge: 30 * 24 * 60 * 60 * 1000,
        keys: [keys.cookieKey]
    })
);
app.use(passport.initialize());
app.use(passport.session());

// init routes
const authRoutes = require("./routes/authRoutes")(app);

Answer 6

就我而言（同样的错误消息），我正在开发一个自定义策略，并且我不需要使用会话。我只是忘记在我的路由 authenticate 中间件中添加 session: false。

  app.post('/api/public/auth/google-token',
    passport.authenticate('google-token', {
      session: false
    }),
    function (req: any, res) {
      res.send("hello");
    }
  );

Answer 7

将app.use(passport.initialize()) 中间件放在app.router 中间件前面，它的作用就像一个魅力

Answer 8

您所要做的就是将此代码放在您使用的路由器之前

app.use('/users', usersRouter);//this is the router  I am using

//and this is the code you have to copy

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