【问题描述】：

我开始使用护照、车把和 mysql 来学习 node.js。

我想创建一个注册页面，其中包含电子邮件地址、密码、名字和姓氏。但是在护照上，它只需要用户名和密码。

passport.use('local-signup', new passportlocal.Strategy({
        // by default, local strategy uses username and password, we will override with email
        usernameField : 'email',
        passwordField : 'password',
        passReqToCallback : true // allows us to pass back the entire request to the callback
    },
function(req, email, password, done){
    connection.query("select * from userInfo where email = '"+email+"'", function(err, res){       
        if(err){
            console.error('error');
            // done(null, null);
            return done(null, false, { message: req.flash('error', 'Please fill your data correctly') });
            // return;
        }
        if (res.length) {
            console.log('user exist');
            return done(null, false, { message: req.flash('error', 'That email is already registered.') });
        }
        else{                
            // create the user
            var newUserMysql = new Object();
            newUserMysql.email = email;
            newUserMysql.password = password;
            newUserMysql.firstName = req.firstName;

            console.log(newUserMysql.firstName);

            var insertQuery = "INSERT INTO userInfo ( email, password, firstName ) values ('" + email +"','"+ password +"','"+ firstName +"')";

            connection.query(insertQuery,function(err,rows){
            newUserMysql.id = rows.insertId;

            // send mail with defined transport object
            app.locals.mailer.sendMail(mailOptions, function(error, info){
                if(error){
                    return console.log(error);
                }
                console.log('Message sent: ' + info.response);
            });

            return done(null, newUserMysql);
            }); 

        }
    })
}));

以下是我的车把的代码

<div class="ui vertical stripe segment">
    <div class="ui text container">
        <form action="" method="post">

            {{#if message}}
            <div class="ui red message">{{message}}</div>
            {{/if}}

            <div class="content">

            <p></p>

            <div class="content">

                    <div class="ui fluid input">

            <p></p>

            <div class="content">
                <div class="field required">    
                    <label>Repeat Password</label>
                    <div class="ui fluid input">
                            <input type="password" name="repeatPassword" placeholder="Repeat Password">

                        <input type="text" name="firstName" placeholder="First Name">
                    </div>
                </div>
            </div>  

            <p></p>

            <div class="content">
                <div class="field required">    
                    <label>Last Name</label>
                    <div class="ui fluid input">
                        <input type="text" name="lastName" placeholder="Last Name">
                    </div>
                </div>
            </div>  

            <p></p>

            <div class="content">
                <div class="field required">    
                    <label>Phone Number</label>
                    <div class="ui fluid input">
                        <input type="text" name="phoneNum" placeholder="Phone Number">
                    </div>
                </div>
            </div>  

            <p></p>

            <button class="ui yellow button">Sign Up</button>

            <div class="ui horizontal divider">
                OR
            </div>

            Already have an account? Please <a href="/login" class="item">Login here!</a> 
        </form>
    </div>
</div>

我尝试了以下solution，但它不适合我。

我认为我从车把获取输入数据到护照的方式是错误的，但我想不通。

谢谢。

【问题讨论】：

LocalStrategy 只接受回调中的用户名和密码字段，因为您可以访问请求对象，您可以像普通 HTTP 请求一样从请求正文 (req.body.firstName) 访问所需的属性。
对不起，我没有阅读您发布的另一个问题，但是首先查看您的代码是使用 req.body.firstName 来访问 firstName 变量。第二，你是如何发送请求的？
嗨@JoseHermosillaRodrigo，它通过添加请求正文（req.body.firstName）来工作。感谢您的帮助！
不客气！！您发布的答案也有一个很好的答案，其中提到了这一点！

【解决方案1】：

在 Jose 的帮助下弄清楚，这两个语句都应该添加一个 (req.body.firstName)

 else{                
        // create the user
        var newUserMysql = new Object();
        newUserMysql.email = email;
        newUserMysql.password = password;
        newUserMysql.firstName = req.body.firstName;

        console.log(newUserMysql.firstName);

        var insertQuery = "INSERT INTO userInfo ( email, password, firstName ) values ('" + email +"','"+ password +"','"+ req.body.firstName +"')";
