email_verified_at

    public function confirmEmail($token)
    {
        $user = User::where('activation_token', $token)->firstOrFail();

        $user->activated = true;
        $user->activation_token = null;
        $user->email_verified_at = now();
        $user->save();

        Auth::login($user);
        session()->flash('success', '恭喜你，激活成功！');
        return redirect()->route('users.show', [$user]);
    }

• $user->email_verified_at = now();
• 是不是要加一行这个，不然这个字段做什么用
