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, ], ]; -
