【问题描述】：

我正在尝试使用已在表单中注册的用户登录，但出现以下错误：

错误：需要数据和哈希参数

感谢 bcrypt，用户在我的数据库中注册了用户名、全名和哈希密码。

const pool = require("./pool");
const bcrypt = require("bcrypt");

function User() 

User.prototype = 
  find: function(user = null, callback) 

  if (user) 
      var field = Number.isInteger(user) ? "id" : "username";
    
    let sql = `SELECT * FROM users WHERE $"" + field + "" = ?`;
    pool.query(sql, user, function(err, result) 
      if (err) console.log(err);
      callback(result);
    );
  ,

  create: function(body, callback) 
    let pwd = body.password;
    body.password = bcrypt.hashSync(pwd, 10);

    var bind = [body.username, body.fullname, body.password];
    console.log(bind);

    let sql =
      "INSERT INTO users(username, fullname, password) VALUES (?, ?, ?)";

    pool.query(sql, bind, function(err, lastId) 
      if (err) throw err;
      callback(lastId);
    );
  ,

  login: function(username, password, callback) 
    this.find(username, function(user) 
      if (user) 
        if (bcrypt.compareSync(password, user.password)) 
          callback(user);
          return;
        
      
    );
  
;

module.exports = User;

一旦我在表单中按下登录按钮，这就是我遇到的错误

  throw err; // Rethrow non-mysql errors

【参考方案1】：

确保您在两个参数中都传递了有效值。 userpassword 和 dbpassword 不应为 undefined 或 null

【参考方案2】：

尝试同步生成盐，更新这一行

body.password = bcrypt.hashSync(pwd, 10);

为

body.password = bcrypt.hashSync(pwd, bcrypt.genSaltSync(10));

【讨论】：

不起作用：/ 我认为我的 compareSync 参数中缺少某些内容

【参考方案3】：

请检查password 和user.password 不等于未定义。因为同样的功能对我来说很好用。 如果您仍然面临同样的问题，请尝试bcrypt.compare。 bcrypt.compare 接受 3 个参数 passwordToCheck、passwordHash 和一个回调。

login: function(username, password, callback) 
    this.find(username, function(user) 
        if (user) 
            bcrypt.compare(password,  user.password, function(err, match) 
                if (err) throw new Error(err);
                else if (match == false) 
                    return res.json(
                        success: false,
                        message: 'Wrong Password'
                    )
                 else 
                    callback(user);
                    return;
                
            );
        
    );
;
