if(err)throw err;错误:非法参数:字符串，未定义 [英] if(err) throw err; Error: Illegal arguments: string, undefined

问题描述

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

似乎这里显示的是密码，但没有显示哈希.

It seems here the password is getting shown but not the hash.

原始

我收到以下错误，不确定是什么原因造成的

Hi I'm getting the following error, not sure what's causing it

正在创建用户，我无法登录.

The users are being created I just can't sign in.

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);
  });
}

这是护照的实施方式

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

推荐答案

在我的情况下，错误是-

In my case the error was -

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...

这是因为密码正确无误，并且引发了错误！我刚刚将输入的密码转换为字符串！

It was because the password was in number and it was throwing an error! I just converted the entered password into string!

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，将其转换为字符串！

After Solving Error- What I did is, I added .toString() function in the password argument to convert it into string!

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.
