護照登記成功回調

Question

router.post('/register', function(req, res, next){
    var name            = req.body.name;
    var email           = req.body.email;
    var username        = req.body.username;
    var password        = req.body.password;
    var password2       = req.body.password2;

    req.checkBody('name', 'Name field is required').notEmpty();
    req.checkBody('email', 'Email field is required').notEmpty();
    req.checkBody('email', 'Email must be a valid email address').isEmail();
    req.checkBody('username', 'Username field is required').notEmpty();
    req.checkBody('password', 'Password field is required').notEmpty();
    req.checkBody('password2', 'Passwords do not match').equals(req.body.password);

    var errors = req.validationErrors();

    if(errors){
        res.render('register');

    } else {

        passport.authenticate('local-register',{
            successRedirect: '/dashboard',
            failureRedirect: '/register'
        })(req, res, next)
    }
});

用戶注冊后，我想執行更多操作，例如在db中輸入相關數據。 但是我不知道護照上的成功回調在哪里

查看護照文件，您應該可以自己重定向響應來實現此目的。

例：

app.post('/login',
  passport.authenticate('local'),
  function(req, res) {
    // If this function gets called, authentication was successful.
    // `req.user` contains the authenticated user.
    res.redirect('/users/' + req.user.username);
  });

因此，您的代碼可能會被修改為類似這樣的內容...

router.post('/register', function(req, res, next){
    var name            = req.body.name;
    var email           = req.body.email;
    var username        = req.body.username;
    var password        = req.body.password;
    var password2       = req.body.password2;

    req.checkBody('name', 'Name field is required').notEmpty();
    req.checkBody('email', 'Email field is required').notEmpty();
    req.checkBody('email', 'Email must be a valid email address').isEmail();
    req.checkBody('username', 'Username field is required').notEmpty();
    req.checkBody('password', 'Password field is required').notEmpty();
    req.checkBody('password2', 'Passwords do not match').equals(req.body.password);

    var errors = req.validationErrors();

    if(errors){
        res.render('register');
    } else {
        passport.authenticate('local-register',{ })(req, res, function(returnCode) {
            // Yay successfully registered user
            // Do more stuff
            console.log(returnCode);     // Check what this value is and redirect accordingly.
            res.redirect('/dashboard/'); // How redirect can potentially be done
       })
    }
});

我不確定returnCode值是什么，因為這將取決於local-register策略的實現。

無論如何， returnCode可以潛在地用於檢查注冊是否成功，並根據其值-相應地重定向用戶。
