Laravel认证系统可以使用现有的数据库吗?

如果需要，可以直接验证:

$user = User::where('email', Input::get('email'))->first();
if( $user && $user->password == md5(Input::get('password')) )
{
    Auth::login($user); /// will log the user in for you
    return Redirect::intended('dashboard');
}
else
{
   /// User not found or wrong password
}

请注意，由Laravel散列的密码是非常安全的，而由MySQL散列的密码则相反。因此，您可以在每次用户登录时转换密码，而无需要求他这样做:

$password = Input::get('password');
$email = Input::get('email');
if (Auth::attempt(array('email' => $email, 'password' => $password)))
{
    return Redirect::intended('dashboard');
}
else
if( $user && $user->password == md5($password) )
{
    Auth::user()->password = Hash::make($password);
    Auth::user()->save();
    return Redirect::intended('dashboard');
}
else
{
    /// User not found or wrong password
}

根据Antonio Carlos Ribeiro的建议(谢谢!)，以下是我对Laravel 5.2的管理方法:

• 在Http/Controllers/Auth/AuthController.php中，复制粘贴vendor/laravel/framework/src/Illuminate/Foundation/Auth/AuthenticateUsers.php
中的login()方法

• 将这些添加到文件的顶部:

  • use Illuminate'Support'Facades'Auth as fAuth;
  • use Hash;

• 替换为

  if (Auth::guard($this->getGuard())->attempt($credentials, $request->has('remember'))) {
      return $this->handleUserWasAuthenticated($request, $throttles);
  }
  

  By this:

  if (fAuth::guard($this->getGuard())->attempt($credentials, $request->has('remember'))) {
      return $this->handleUserWasAuthenticated($request, $throttles);
  } else {
      $user = User::where('email', $request->email)->first();
      if ($user && $user->password == md5($request->password)) {
          $user->password = Hash::make($request->password);
          $user->save();
          if (fAuth::guard($this->getGuard())->attempt($credentials, $request->has('remember'))) {
              return $this->handleUserWasAuthenticated($request, $throttles);
          }
      }
  }
