我得到的错误“返回binding.PBKDF2（口令，盐，迭代KEYLEN，回调）; ^类型错误：不是一个缓冲区”

Question

请参见下面的完整错误代码：

 
crypto.js:601 
    return binding.PBKDF2(password, salt, iterations, keylen, callback); 
       ^
TypeError: Not a buffer 
    at pbkdf2 (crypto.js:601:20) 
    at Object.exports.pbkdf2Sync (crypto.js:592:10) 
    at model.UserSchema.methods.hashPassword (/Users/markie13/documents/mean/meanPassport/app/models/user.server.model.js:59:16) 
    at model.UserSchema.methods.authenticate (/Users/markie13/documents/mean/meanPassport/app/models/user.server.model.js:63:32)

我在Amos Haviv的书MEAN Stack Development中工作，并在第6章中讨论 - 如果有人在意。

下面是引发错误（见行号意见）代码：

UserSchema.pre('save', function (next) { 
    if (this.password) { 
     this.salt = new Buffer(crypto.randomBytes(16).toString('base64'), 'base64'); 
     this.password = this.hashPassword(this.password); 
    } 
    next(); 
}); 
UserSchema.methods.hashPassword = function (password) { 
    return crypto.pbkdf2Sync(password, this.salt, 10000, 64).toString('base64');//line 59 
}; 
UserSchema.methods.authenticate = function (password) { 
    return this.password === this.hashPassword(password);//line 63 
};

所以，事实证明，我被填充蒙戈DB与非散列字符串作为密码。

一旦我用数据库中的哈希密码登录，它工作正常。

现在我需要了解错误检查...
