node js + passport js + mongoose：如何将提供者名称传递给模板

Question

我在 mongoose 模式文档中使用护照 js 进行用户凭证管理：

var customerSchema = new Schema({
    info: {
        firstname: String,
        lastname: String,
        telephone: String,
        fax: String
    },
    local: {
        email: {
            type: String
        },
        password: {
            type: String
        }
    },
        facebook: {
        id: String,
        token: String,
        email: String,
        name: String,
        photo: String
    },
    google: {
        id: String,
        token: String,
        email: String,
        name: String,
        photo: String
    },
    status: String
}, {
    timestamps: true
});

使用passportjs登录并添加提供者名称时：

passport.use('local.login', new LocalStrategy({
    usernameField: 'email',
    passwordField: 'password',
    passReqToCallback: true
}, function(req, email, password, done) {
    req.checkBody('email', 'Email address invalid.').notEmpty().isEmail();
    req.checkBody('password', 'Password invalid.').notEmpty();

    var errors = req.validationErrors();

    if (errors) {
        var messages = [];
        errors.forEach(function(error) {
            messages.push(error.msg);
        });
        return done(null, false, req.flash('error', messages));
    }
    //find user
    Customer.findOne({
        'local.email': email
    }, function(err, customer) {
        if (err) {
            return done(err);
        }

        if (!customer) {
            return done(null, false, {
                message: 'Customer not found.'
            });
        }
        if (!customer.validPassword(password)) {
            return done(null, false, {
                message: 'Customer info invalid.'
            });
        }
        customer.provider = "local"; //Add more var to customer info
        console.log("User Info: " + customer.provider);
        return done(null, customer);
    });

}));

passport.serializeUser(function(user, done) {
    console.log("Serialize User: " + user);
    done(null, user._id);
});

当通过本地护照或 Facebook 登录时，我想将自定义字段添加到护照会话返回提供者信息传递到模板。

那么我如何在 Passport 中做到这一点？

更新 1：

定义变量：

var provider = null;

在：

...
if (!customer.validPassword(password)) {
        return done(null, false, {
             message: 'Customer info invalid.'
        });
}
provider = "local"; //Add more var to customer info
return done(null, customer);
...

我使用了@Love-Kesh 帮助代码：

passport.deserializeUser(function(customerId, done) {

    Customer.findById(customerId, function(err, user) {

        var newUser = user.toObject();
        newUser['provider'] = provider;

        done(err, newUser);
    });
});

这对我来说很正常。提供者通过本地方法返回动态值，facebook ...

    passport.use('local.login', new LocalStrategy({
    usernameField: 'email',
    passwordField: 'password',
    passReqToCallback: true
}, function(req, email, password, done) {
    req.checkBody('email', 'Email address invalid.').notEmpty().isEmail();
    req.checkBody('password', 'Password invalid.').notEmpty();

    var errors = req.validationErrors();

    if (errors) {
        var messages = [];
        errors.forEach(function(error) {
            messages.push(error.msg);
        });
        return done(null, false, req.flash('error', messages));
    }


    //check if user local 
    //need to pass provider from client side
    if(req.body.provider=='local'){

        //find user
        Customer.findOne({
            'local.email': email
        }, function(err, customer) {
            if (err) {
                return done(err);
            }

            if (!customer) {
                return done(null, false, {
                    message: 'Customer not found.'
                });
            }
            if (!customer.validPassword(password)) {
                return done(null, false, {
                    message: 'Customer info invalid.'
                });
            }
        customer.provider = "local"; //Add more var to customer info
        console.log("User Info: " + customer.provider);
        return done(null, customer);
    });

    }else{

        //do whatever you want

    }
});

}



}));

passport.serializeUser(function(user, done) {
    console.log("Serialize User: " + user);

    //pass complete user here 
    done(null, user);
});

更新以下代码

passport.deserializeUser(function(loggedUser, done) {
            var provider = loggedUser.provider;

           Customer.findById(loggedUser.id,function(error, user) {

            //need to convert into object
            var newUser=user.toObject();                   
            newUser['provider']=provider;

            return done(null, newUser);



        });

          //or return direct  return done(null, loggedUser);
       });

Answer 2

如果我没记错的话，您想在passport session 上添加额外信息。

所以，如果您想在护照会话中添加自定义信息，那么您可以将其添加到 deserializeUser

passport.deserializeUser(function(id, done) {
    getUser(id).then(function(user) {
        user.anything = 'whatever you want';
        return done(null, user);
    });
});
