Passport + Node.js/添加用户后自动登录 [英] Passport + Node.js / Automatic login after adding user

问题描述

我正在使用护照进行身份验证和会话处理.到目前为止一切正常.我实现了登录"表单，以将新用户添加到该应用中.添加用户后，我想自动登录.

I am using passport for authentication and session handling. Everything works fine so far. I implemented a "Sign in" form to add new users to the app. After a user is added I would like to log him/her in automatically.

实现此目标的最佳方法是什么-我应该使用用户凭据重定向到"/登录"还是有另一种/更好的方法(调用serializeUser)来做到这一点?

What is the best way to achieve this - should I redirect to "/login" with the user credentials or is there another/better way(call serializeUser) to do that?

到目前为止，我认为我还不太了解完成"功能(在serializeUser和LocalStrategy中)的工作方式或工作方式...

So far I think I did not really understand the way the "done" function (in serializeUser and LocalStrategy) is working or what it is doing ...

这是我的代码:

passport.serializeUser(function(user, done) {
    done(null, user._id);
});
passport.deserializeUser(function(id, done) {
    authProvider.findUserById('users', id, function (err, user) {
        done(err, user);
    });
});

passport.use(new LocalStrategy( function(email, password, done) {
    authProvider.getUserByEmail('users', email, function(error, user){
        if(error) { return done(error); }
        if (!user) { return done(null, false, { message: 'Unknown user ' + email });}   
        if (user.password != password) { return done(null, false);}
        return done(null, user);
        });
    }
));

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

app.post('/sign', function(req, res){
    authProvider.saveUser(...do stuff), function(error, user){
        if(error){
            res.redirect('/sign');
        } else {
            res.redirect('/');
        }
    });
});

有人知道该怎么做吗?

推荐答案

请使用来自 @Weston的波纹管中的代码，因为它更通用，更直接

Please use code from the @Weston answer bellow, because it's more universal and straightforward

应该看起来像这样

app.post('/sign', function(req, res){
    authProvider.saveUser(...do stuff), function(error, user){
        if(error){
            res.redirect('/sign');
        } else {
            passport.authenticate('local')(req, res, function () {
                res.redirect('/account');
            })
        }
    });
});         

我不确定策略的名称，但是默认情况下，LocalStrategy应该提供本地"名称

I don't sure about name of strategy, but by default LocalStrategy should provide 'local' name
