【问题描述】：

我正在尝试在用户使用 nodemailer 注册后发送欢迎电子邮件，并在同一发布路线上使用 passport.authenticate 将用户添加到 mongodb。我可以让它单独工作，即发送电子邮件或将用户添加到数据库，但似乎无法让它们一起工作。我是 nodejs 的新手，非常感谢任何帮助。这是我要上班的路线：

  router.post('/signup', function(req, res,next) 
  async.waterfall([
    function(done) 
      passport.authenticate('signup', 
            successRedirect: '/',
            failureRedirect: '/signup',
            failureFlash : true
        );
    ,
    function(user, done) 
      var transporter = nodeMailer.createTransport(
        service: 'SendGrid',
        auth: 
          user: 'user',
          pass: 'password'
        
      );
      var mailOptions = 
        to: user.email,
        from: '[e-mail]',
        subject: 'Welcome to the site',
        html: '<p> This is html, did I render correctly?</p>'
      ;
      transporter.sendMail(mailOptions, function(err)
        done(err);
      );
    
  ], function(err) 
    res.redirect('/signup');
  );
);

这是使用护照的注册策略：

var LocalStrategy   = require('passport-local').Strategy;
var User = require('../models/user');
var bCrypt = require('bcrypt-nodejs');


module.exports = function(passport)

    passport.use('signup', new LocalStrategy(
            usernameField : 'email',
            passReqToCallback : true
        ,
        function(req, email, password, done) 

            findOrCreateUser = function()
                // find a user in Mongo with provided username
                User.findOne( 'email' :  email , function(err, user) 
                    // In case of any error, return using the done method
                    if (err)
                        req.flash('error','Email Already Exists',err.message);
                        return done(err);
                    
                    // already exists
                    if (user) 
                        console.log('User already exists with username:');
                        return done(null, false, req.flash('error','Email Already Exists'));
                     else 
                        // if there is no user with that email
                        // create the user
                        var newUser = new User();

                        // set the user's local credentials
                        newUser.password = createHash(password);
                        newUser.email = req.param('email');
                        newUser.firstName = req.param('firstName');
                        newUser.lastName = req.param('lastName');

                        // save the user
                        newUser.save(function(err) 
                            if (err)
                                console.log('Error in Saving user: '+err);
                                return done(null, false, req.flash('error',err.message));
                            
                            console.log('User Registration succesful');
                            return done(null, newUser);
                        );
                    
                );
            ;
            // Delay the execution of findOrCreateUser and execute the method
            // in the next tick of the event loop
            process.nextTick(findOrCreateUser);
        )
    );

    // Generates hash using bCrypt
    var createHash = function(password)
        return bCrypt.hashSync(password, bCrypt.genSaltSync(10), null);
    

提前感谢您的帮助！

【参考方案1】：

为什么不将电子邮件发送逻辑移至护照注册策略？

【讨论】：

成功了！猜猜我试图通过将其添加到路线来使其过于复杂。我只是把用户成功保存后的email逻辑放到了signup.js文件中，谢谢！
