laravel 用中间件解决能够处理正常跨域问题，但当出现异常的时候大家是怎么处理的呢？

处理跨域用的官方的barryvdh/laravel-cors包，但试了下 HttpException 的 header 属性上写死加上Access-Control-Allow-Origin'=>'*'还是不行。

namespace Symfony\Component\HttpKernel\Exception; /** * HttpException. * * @author Kris Wallsmith <[email protected]> */ class HttpException extends \RuntimeException implements HttpExceptionInterface { private $statusCode; private $headers; public function __construct($statusCode, $message = null, \Exception $previous = null, array $headers = [], $code = 0) { $this->statusCode = $statusCode; $this->headers = ['Access-Control-Allow-Origin'=>'*']; parent::__construct($message, $code, $previous); }
