Sails: sails-mysql 导致 passport-local 出错？

Question

我在这上面花了 3 天的大部分时间

我正在开发一个 Sails 应用程序，同时自学 Sails 和 Node。我正在关注 This Tutorial，尽管由于 bcrypt 的 windows 要求非常疯狂，我不得不在这里和那里进行一些更改，但我得到了它的大部分工作。我的问题似乎在教程 config/passport.js 文件中。在进行调试时，我最终修改了一些内容。

准确的错误是

C:\Users\Jhecht\Desktop\sails\students\node_modules\sails-mysql\node_modules\mysql\lib\protocol\Parser.js:77

config/passport.js

var passport = require('passport'),
    LocalStrategy = require('passport-local').Strategy,
    bcrypt = require('bcrypt-nodejs');

passport.serializeUser(function (user, done) {
    done(null, user.user_id);
});

passport.deserializeUser(function (id, done) {
    Users.findOne({
        user_id: id
    }, function (err, user) {
        done(err, user);
    });
});

passport.use(new LocalStrategy({
        usernameField: 'user_email',
        passwordField: 'user_password'
    },
    function (email, password, done) {
        Users.findOne({
            user_email: email
        }, function (err, user) {
            if (err) {
                return done(err);
            }
            if (!user) {
                return done(null, false, {
                    message: 'Email not found, are you sure you registered?'
                });
            }

            if (bcrypt.compareSync(password, user.user_password)) { //Changed from tutorial to see if the error was coming from the async function
                console.info("User Found, Hashes are equal."); //Me finding errors
                done(null, user, {
                    message: 'Login Successful'
                });
                //Removing this line I don't get the error in the console and the server doesn't reset, but without it the authentication doesn't work
            }
        });
    }
));

很遗憾，我对 Sails/Node 的了解还不够，无法弄清楚到底发生了什么。该错误似乎是由 sails-mysql 适配器引发的，但如果调用 done() 函数，则仅。但是，如果没有 done() 调用，我无法让 Passport 授权用户。

非常感谢您给我的任何指示。

本教程在 AuthController.js 中包含错误，在 this comment 中提到的 login() 函数中缺少 return。 req.logIn() 部分应该是：

req.logIn(user, function(err) {
    if (err) return res.send(err);
    return res.send({
        message: info.message,
        user: user
    });
});
