Laravel 解决跨域和OPTIONS请求问题 建立或现用公共中间件中handle方法改为如下代码public function handle(Request $request, Closure $next) { /** * 用于跨域调用 */ if($request->isMethod('OPTIONS')){ $response = response('',200); }else{ $response = $next($request); } if($referrer = $request->server('HTTP_REFERER') ?? $request->server('HTTP_ORIGIN')){ preg_match('/^(http[s]?:\/\/)?([^\/]+)/i', $referrer, $match); $response->header('Access-Control-Allow-Origin',"{$match[0]}"); $response->header('Access-Control-Allow-Methods', 'POST, GET, OPTIONS, DELETE'); $response->header('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type, Accept, Authorization, Cookies, Token,content-type'); $response->header('Access-Control-Allow-Credentials', 'true'); $response->header('Cache-Control', 'no-store'); } return $response; }
