if(err) 抛出错误；错误：非法参数：字符串，未定义

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

这里似乎显示了密码，但没有显示哈希值。

您好，我收到以下错误，不知道是什么原因造成的

正在创建用户，我只是无法登录。

这是导致错误的行

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

这是护照的实施

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'});
        }
      });
    });
  }));

有同样的问题。

为传入的值添加 console.log() 显示它们是“未定义”。

我使用 Postman 测试了端点，将值添加到所需字段，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。
