Laravel 5:Auth :: guard($ this-> getGuard())-> login($ user)之间的区别；和auth()-> login($ user); [英] Laravel 5: The difference between Auth::guard($this->getGuard())->login($user); and auth()->login($user);

问题描述

两者之间有什么区别

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

和

auth()->login($user);

?例如，在PasswordController.php中，我们可以拥有:

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

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

    $user->save();

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

或

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

    $user->save();

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

(在这种情况下，我们在 Users.php 中创建一个变量来加密密码，而不是在 resetPassword($ user，$ password)中而不是默认值)

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

特别是，guard($ this-> getGuard())是什么，它有什么作用(guard()，getGuard())?

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

推荐答案

没有什么区别，auth函数只是一个返回\Illuminate\Contracts\Auth\Guard实例的助手.

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