中间件跨域

public function handle($request, Closure $next)
{
$response = $next($request);
$origin = $request->server(‘HTTP_ORIGIN’) ? $request->server(‘HTTP_ORIGIN’) : ‘’;
$allow_origin = [
‘http://.com’,//允许访问
‘http://.com’,//允许访问
];
if (in_array($origin, $allow_origin)) {
$response->header(‘Access-Control-Allow-Origin’, $origin);
$response->header(‘Access-Control-Allow-Headers’, ‘Origin, Content-Type, Cookie, X-CSRF-TOKEN, Accept, Authorization, X-XSRF-TOKEN’);
$response->header(‘Access-Control-Expose-Headers’, ‘Authorization, authenticated’);
$response->header(‘Access-Control-Allow-Methods’, ‘GET, POST, PATCH, PUT, OPTIONS’);
$response->header(‘Access-Control-Allow-Credentials’, ‘true’);
}
return $response;
}

protected $middleware = [
// more
App\Http\Middleware\EnableCrossRequestMiddleware::class,
];
在 App\Http\Kernel 类的 $middleware 属性添加，这里注册的中间件属于全局中间件。

接口频率限制
Route::group([‘prefix’=>’api’,’middleware’=>’throttle:5’],function(){
Route::get(‘users’,function(){
return \App\User::all();
});
});//频次上限5
