node.js - 错误: Unknown authentication strategy "[object Object]"

Question

POST localhost/api/login 使用(正确的)数据 username=test password=test 给出以下内容:

Error: Unknown authentication strategy "[object Object]"
   at attempt (/var/www/node_modules/passport/lib/middleware/authenticate.js:166:37)
   at authenticate (/var/www/node_modules/passport/lib/middleware/authenticate.js:342:7)

路线:

app.post('/api/login', passport.authenticate(new LocalStrategy(function(username, password, done) {
  db.User.findOne({username: username}, function(err, user) {
    if (err) return done(err);
    if (!user) return done(null, false, { message: 'Username or password incorrect' });
    bcrypt.compare(password, user.passHash, function(err, res) {
      if (err) return done(err);
      if (!res) return done(null, false, { message: 'Username or password incorrect' });
      return done(null, user);
    })
  })
})))

我正在运行 bodyParser，并且我知道它正在从我的注册路线运行。这里发生了什么？我一直在使用http://passportjs.org/guide指南并且已经掌握了基础知识，但是为什么会发生这种情况？

authenticate() 不接受对象，它接受一个包含您之前配置的策略名称的字符串。您的 new LocalStrategy() 被传递给 passport.use()。

因此，您可以在中间件定义中执行此操作:

passport.use(new LocalStrategy(function(username, password, done) {
  db.User.findOne({username: username}, function(err, user) {
    if (err)
      return done(err);
    if (!user)
      return done(null, false, { message: 'Username or password incorrect' });
    bcrypt.compare(password, user.passHash, function(err, res) {
      if (err)
        return done(err);
      if (!res)
        return done(null, false, { message: 'Username or password incorrect' });
      return done(null, user);
    })
  })
}));

然后你为你的路线做这样的事情:

app.post('/api/login',
  passport.authenticate('local'),
  function(req, res) {
    // authentication successful
  });
