laravel 使用中间件解决跨域问题

创建中间件：

php artisan make:middleware CrossHttp

在中间件的中添加下列代码：这个是所有域都能访问

public function handle($request, Closure $next)
    {
        $response = $next($request);
        $response->header('Access-Control-Allow-Origin', '*');
        $response->header('Access-Control-Allow-Headers', 'Origin, Content-Type, Cookie, Accept');
        $response->header('Access-Control-Allow-Methods', 'GET, POST, PATCH, PUT, OPTIONS');
        $response->header('Access-Control-Allow-Credentials', 'false');
        return $response;
    }

指定域名访问：

$response->header('Access-Control-Allow-Origin', 'http://mytest.com');

设置\app\Http\Kernel.php

全局访问：
