Question

我现在有

module.exports.comparePassword = function(candidatePassword, hash, callback) {
  console.log(candidatePassword)
 console.log(hash)
  bcrypt.compare(candidatePassword, hash, function(err, ismatch) {
    if(err) throw err;
    callback(null, ismatch);
  });
}

现在的日志是

这里似乎显示的是密码，但不是哈希。

嗨，我收到以下错误，不知道是什么导致它

正在创建用户我无法登录。

以下是导致错误的行

module.exports.comparePassword = function(candidatePassword, hash, callback) {
  bcrypt.compare(candidatePassword, hash, function(err, ismatch) {
    if(err) throw err;
    callback(null, ismatch);
  });
}

这是护照实施

passport.use(new LocalStrategy({
  usernameField: 'email'
  },
  function(email, password, done) {
    User.getUserByEmail(email, function(err, user){
      if(err) throw err;
      if(!user){
        return done(null, false, {message: 'Unknown Email Address'});
      }

      User.comparePassword(password, user.password, function(err, ismatch){
        if(err) throw err;
        if(ismatch){
          return done(null, user);
        } else {
          return done(null, false, {message: 'Invalid password'});
        }
      });
    });
  }));

在我的情况下，错误是-

E:\web\Projects\webapp\auth.js:15
                if(err) throw err;
                        ^

Error: Illegal arguments: number, string
    at _async (E:\web\Projects\webapp\node_modules\bcryptjs\dist\bcrypt.js:286:46)
    at Object.bcrypt.compare (E:\web\Projects\webapp\node_modules\bcryptjs\dist\bcrypt.js:304:13)
    at Promise (E:\web\Projects\webapp\auth.js:11:20)
    at process._tickCallback (internal/process/next_tick.js:68:7)
[nodemon] app crashed - waiting for file changes before starting...

这是因为密码是数字，并且抛出错误！我刚刚将输入的密码转换为字符串！

解决错误之前的代码-

bcrypt.compare(password.toString(), user.password, (err, isMatch)=>{
                if(err) throw err;
                if(isMatch){
                    resolve(user);
                }else{
                    //Password Wrong
                    reject("Auth Failed");
                }
            });

解决错误后- 我所做的是，我在password参数中添加了.toString()函数以将其转换为字符串！

bcrypt.compare(password.toString(), user.password, (err, isMatch)=>{
                if(err) throw err;
                if(isMatch){
                    resolve(user);
                }else{
                    //Password Wrong
                    reject("Auth Failed");
                }
            });

我希望它能对某人有所帮助。

Answer 2

尝试console .log()一些值，以确保一切都得到很好的定义。

module.exports.comparePassword = function(candidatePassword, hash, callback) {
  console.log(candidatePassword)
  console.log(hash)
  bcrypt.compare(candidatePassword, hash, function(err, ismatch) {
    if(err) throw err;
    callback(null, ismatch);
  });
}

Answer 3

有同样的问题。

为传入的值添加console.log（）表示它们是“未定义”。

我使用Postman测试了端点，以便将值添加到必填字段中，从而解决了问题。

结论：密码可能为空。使用console.log（）检查它是否未定义。然后传递一些值给它。

Answer 4

错误：非法参数：string，undefined可能意味着编译器无法识别您的哈希值或用户输入。首先尝试将输入内容与用户（从数据库返回的内容）一起记录，如果您的user.password未返回字符串，则应检查Schema是否已预定义了字符串，并确保您不使用它select: false用您的密码输入，它可能会限制查询。

Answer 5

您可能已在密码上将select属性设置为false。这会导致错误。猫鼬不返回密码，因为您已将select设置为false。现在，您需要在查询时明确要求输入密码。在要查询用户的位置使用select方法，并将+ password作为这样的字符串传递。

.select('+password')

Answer 6

我过去使用MariaDB处理此问题，而罪魁祸首是大写的表列PASSWORD。当我将其更改为小写字母时，一切正常。

Answer 7

不要忘记使用toObject()：

var pass = user.toObject().userPass;

if（err）throw err;错误：非法参数：字符串，未定义
