我正在使用多种护照策略（本地和不记名策略）。使用本地策略登录有效。我们登录后生成一个token，token存放在redis中。初始登录后，只要在 redis 中找到令牌，我就想使用不带会话的承载身份验证。如果我发送正确的令牌，我可以查询 redis 并获取用户数据，但节点仍然发送 403 响应而不是我期望的 200 状态代码。如果在 redis 中找不到令牌，sails 会崩溃并出现以下错误：

 /workspace/rs-api-sails/node_modules/redis/index.js:587
            throw err;
                  ^

这是 bootstrap.js 中承载身份验证的代码：

passport.use(new BearerStrategy(
  function(token, done) {
    var redis = require("redis"),
    client = redis.createClient(null, null, {detect_buffers: true});

    client.get(token, function (err, reply) {
      if (reply === null) {
        // if token is not a key in redis, node throws the headers already sent error
        return done(null, false);
      } else {
        User.findOne({ id: reply.toString() }).done(function(err, user) {
          sails.log(user);

          // here we get the user data from waterline but node still sends a 403
          return done(null, user);
        });
      }
    });
  }
));

此代码在策略/isAuthenticated.js 中：

module.exports = function(req, res, next) {
  var passport = require('passport');    

  passport.authenticate('bearer', { session: false })(req, res, next);  

  // User is allowed, proceed to the next policy, 
  // or if this is the last policy, the controller
  if (req.isAuthenticated()) {
    return next();
  }

  // User is not allowed
  // (default res.forbidden() behavior can be overridden in `config/403.js`)
  return res.forbidden('You are not permitted to perform this action.');
};

我是节点新手，非常感谢任何帮助！

更新：在对政策/isAuthenticated.js 进行一些更改后似乎现在可以工作：

var passport = require('passport');   

module.exports = function(req, res, next) { 

  passport.authenticate('bearer', { session: false }, function(err, user, info) {

    if (req.isAuthenticated()) {
      // user is allowed through local strategy
      return next();
    }  

    if (err) {
      return res.send(403, { error: 'Error: ' + info });        
    }

    if (!user) {
      return res.send(403, { error: 'Invalid token' });
    } 

    if (user) {
      sails.log(user);
      return next();
    }

    // (default res.forbidden() behavior can be overridden in `config/403.js`)
    return res.forbidden('You are not permitted to perform this action.');    

  })(req, res, next);

};
