Answer 1

这就是我们如何在Laravel 5.2电子邮件或用户名验证，看看我的AuthController的代码，类似的情况

namespace App\Http\Controllers\Auth; 
use App\User; 
use Validator; 
use App\Http\Controllers\Controller; 
use Illuminate\Foundation\Auth\ThrottlesLogins; 
use Illuminate\Foundation\Auth\AuthenticatesAndRegistersUsers; 
use Illuminate\Http\Request; 
use Illuminate\Support\Facades\Auth; 
use Illuminate\Support\Facades\Lang; 

class AuthController extends Controller 
{ 
    use AuthenticatesAndRegistersUsers, ThrottlesLogins; 
    protected $redirectTo = '/'; 
    protected $username = 'username'; 
    protected $maxLoginAttempts = 10; 
    protected $redirectPath = '/'; 
    protected $redirectAfterLogout = '/'; 

    /** 
    * Create a new authentication controller instance. 
    * 
    * @return void 
    */ 
    public function __construct() 
    { 
     $this->middleware('guest', ['except' => 'logout']); 
    } 

    /** 
    * Get a validator for an incoming registration request. 
    * 
    * @param array $data 
    * @return \Illuminate\Contracts\Validation\Validator 
    */ 
    protected function validator(array $data) 
    { 
     return Validator::make($data, [ 
      'name' => 'required|max:255', 
      'email' => 'required|email|max:255|unique:syscare_users', 
      'password' => 'required|confirmed|min:6', 
      'username' => 'max:255|min:6|alpha_num|unique:syscare_users', 
     ]); 
    } 


    /** 
    * Handle a login request to the application. - Overriding 
    * 
    * @param \Illuminate\Http\Request $request 
    * @return \Illuminate\Http\Response 
    */ 
    public function login(Request $request) 
    { 
     $this->validate($request, [ 
      $this->loginUsername() => 'required', 'password' => 'required', 
     ]); 

     // If the class is using the ThrottlesLogins trait, we can automatically throttle 
     // the login attempts for this application. We'll key this by the username and 
     // the IP address of the client making these requests into this application. 
     $throttles = $this->isUsingThrottlesLoginsTrait(); 

     if ($throttles && $this->hasTooManyLoginAttempts($request)) { 
      return $this->sendLockoutResponse($request); 
     } 

     $credentials = $this->getCredentials($request); 

     if (Auth::attempt(['username' => $request->username , 'password' => $request->password], $request->has('remember'))) { 
      return $this->handleUserWasAuthenticated($request, $throttles); 
     } 
     elseif(Auth::attempt(['email' => $request->username , 'password' => $request->password],$request->has('remember'))) 
     { 
      return $this->handleUserWasAuthenticated($request, $throttles); 
     } 


     // If the login attempt was unsuccessful we will increment the number of attempts 
     // to login and redirect the user back to the login form. Of course, when this 
     // user surpasses their maximum number of attempts they will get locked out. 
     if ($throttles) { 
      $this->incrementLoginAttempts($request); 
     } 

     return redirect()->back() 
      ->withInput($request->only($this->loginUsername(), 'remember')) 
      ->withErrors([ 
       $this->loginUsername() => $this->getFailedLoginMessage(), 
      ]); 
    } 

    /** 
    * Get the failed login message. - Override 
    * 
    * @return string 
    */ 

    protected function getFailedLoginMessage() 
     { 
      return Lang::has('auth.failed') 
       ? Lang::get('auth.failed') 
       : 'Invalid username/email or password.'; 
     } 

} 

Answer 2

您可以使用以下方法。

public function login(LoginRequest $request) 
     { 
      $field = filter_var($request->input('login'), FILTER_VALIDATE_EMAIL) ? 'email' : 'username';//Validating if user has entered email or username 
      $request->merge([$field => $request->input('login')]);//Use selected field to generate input array 

      if ($this->auth->attempt($request->only($field, 'password')))//authenticate 
      { 
       return redirect('/'); 
      } 

      return redirect('/login')->withErrors([ 
       'error' => 'These credentials do not match our records.', 
      ]); 
     } 

或者你可以使用多次尝试：

if (Auth::attempt(['username' => $request->username, 'password' => $request->password])) { 

     echo "success with username!"; 
} 

elseif (Auth::attempt(['email'=> $request->username, 'password' => $request->password])) { 

     //redirect or do something 
} 


else { 
     //redirect or do something 
}
