我有一个密码存储在数据库哈希与DefaultPasswordHasher添加操作.
我有另一个操作来更改登录用户的密码,在此表单上我有一个名为current_password的字段,我需要将其与数据库中的当前密码值进行比较.@H_404_2@
问题是DefaultPasswordHasher每次为表格的值散列时都会生成不同的哈希值,因此这将永远不会与数据库中的哈希值匹配.@H_404_2@
按照’current_password’字段的验证码：@H_404_2@
->add('current_password','custom',[
'rule' => function($value,$context){
$user = $this->get($context['data']['id']);
if ($user) {
echo $user->password; // Current password value hashed from database
echo '<br>';
echo $value; //foo
echo '<br>';
echo (new DefaultPasswordHasher)->hash($value); // Here is displaying a different hash each time that I post the form
// Here will never match =[
if ($user->password == (new DefaultPasswordHasher)->hash($value)) {
return true;
}
}
return false;
},'message' => 'Você não confirmou a sua senha atual corretamente'
])
这就是bcrypt的工作方式. Bcrypt是一种更强大的密码散列算法,它会根据当前系统熵为相同的值生成不同的散列,但是能够比较原始字符串是否可以散列为已经散列的密码.
原文链接：/php/133078.html要解决您的问题,请使用check()函数而不是hash()函数：@H_404_2@
->add('current_password',$context){
$user = $this->get($context['data']['id']);
if ($user) {
if ((new DefaultPasswordHasher)->check($value,$user->password)) {
return true;
}
}
return false;
},'message' => 'Você não confirmou a sua senha atual corretamente'
