webman跨域问题

接口等跨域访问增加中间件如下：

use Webman\Http\Response;
use Webman\Http\Request;
use Webman\MiddlewareInterface;

class CrossDomain implements MiddlewareInterface
{

    public function process(Request $request, callable $handler): Response
    {
        $response = $request->method() == 'OPTIONS' ? response('') : $handler($request);
        // 给响应添加跨域相关的http头
        $response->withHeaders([
            'Access-Control-Allow-Credentials' => 'true',
            'Access-Control-Allow-Origin' => $request->header('origin', '*'),
            'Access-Control-Allow-Methods' => $request->header('access-control-request-method', '*'),
            'Access-Control-Allow-Headers' => $request->header('access-control-request-headers', '*'),
        ]);

        return $response;
    }
}

并在config/middleware.php中修改：

return [
    '' => [
        CrossDomain::class
    ],
];

如果是资源类跨域问题，需要注意就是，官方的后台管理插件和webman需要分别设置跨域中间件：

class StaticFile implements MiddlewareInterface
{
    public function process(Request $request, callable $handler): Response
    {
        // Access to files beginning with. Is prohibited
        if (strpos($request->path(), '/.') !== false) {
            return response('<h1>403 forbidden</h1>', 403);
        }
        /** @var Response $response */
        $response = $handler($request);
        // Add cross domain HTTP header
        $response->withHeaders([
            'Access-Control-Allow-Origin'      => '*',
            'Access-Control-Allow-Credentials' => 'true',
        ]);
        return $response;
    }
}

webman在static.php中设置，webman的管理后台插件，需要在插件中的static.php设置，设置如下：

return [
    'enable' => true,
    'middleware' => [     // Static file Middleware
        StaticFile::class,
    ],
];
