laravel实现Auth认证,登录、注册后的页面回跳方法

 if (Auth::guard($guard)->guest()) {
  if ($request->ajax() || $request->wantsJson()) {
   return response('Unauthorized.', 401);
  } else {
   return redirect()->guest($guard.'/login');
  }
 }

 public function guest($path, $status = 302, $headers = [], $secure = null)
 {
  $this->session->put('url.intended', $this->generator->full()); // 设置回跳地址
 
  return $this->to($path, $status, $headers, $secure);
 }

 protected function handleUserWasAuthenticated(Request $request, $throttles)
 {
  if ($throttles) {
   $this->clearLoginAttempts($request);
  }
 
  if (method_exists($this, 'authenticated')) {
   return $this->authenticated($request, Auth::guard($this->getGuard())->user());
  }
 
  return redirect()->intended($this->redirectPath()); // 获取回跳地址
 }
