Passportjs 成功回调从未被调用

【中文标题】Passportjs 成功回调从未被调用

【英文标题】：Passportjs success callback never called

【问题描述】：

我正在尝试使用护照 js 实现本地身份验证并在 express 中进行均衡。我遇到的问题是成功回调永远不会在成功的身份验证时触发。日志显示找到了用户，但用户对象从未记录在请求回调中，也没有触发 res.send。

路线和策略

passport.use(
  'local',
  new LocalStrategy(
    
      usernameField: 'email',
      passwordField: 'password',
      passReqToCallback: true,
    ,
    (req, email, password, done) => 
      // find user
      User.findOne( where:  email  ).then(user => 
        if (!user) 
          return done(null, false);
        
        if (password !== user.password) 
          return done(null, false);
        
        console.log('user found!');
        return done(null, user);
      );
    ,
  ),
);
app.use(passport.initialize());

// routes
app.post(
  '/login',
  passport.authenticate('local'),
  (req, res) => 
    console.log(req.user);
    res.send('logged in');
    // const expiresIn = 60 * 60 * 24 * 180; // 180 days
    // const token = jwt.sign(req.user, config.auth.jwt.secret,  expiresIn );
    // res.cookie('id_token', token,  maxAge: 1000 * expiresIn, httpOnly: true );
  ,
);

【问题讨论】：

我没有看到任何LocalStrategy接收req作为参数的例子，总是只有3个参数，像这样：（用户名，密码，完成）试着像这个网站的例子那样做：passportjs.org/docs/username-password

DavidVicente 是的，我也尝试删除 req 参数，但没有效果。

【参考方案1】：

我解决了这个问题。再次运行后，我收到错误Error: Failed to serialize user into session。在this question 之后，我添加了以下代码来序列化和反序列化用户并解决问题。

passport.serializeUser(function(user, done) 
  done(null, user);
);

passport.deserializeUser(function(user, done) 
  done(null, user);
);
