Laravel 5：Auth :: guard（$ this-> getGuard（）） - > login（$ user）之间的区别; 和auth（） - > login（$ user）;

Question

What is the difference between:

Auth::guard($this->getGuard())->login($user);

and

auth()->login($user);

? For example, in PasswordController.php we can have:

protected function resetPassword($user, $password)
{
    $user->password = $password;

    $user->save();

    Auth::guard($this->getGuard())->login($user);
}

or

protected function resetPassword($user, $password)
{
    $user->password = $password;

    $user->save();

    auth()->login($user);
}

(in this case, we create a mutator in Users.php to bcrypt password AND NOT in resetPassword($user, $password) as it is by default)

In particular, what is guard($this->getGuard()), what does it do (guard(), getGuard())?

There is no difference, the auth function is just a helper that returns an instance of \\Illuminate\\Contracts\\Auth\\Guard .
