Enable CORS in lumen | 易学教程

问题

I have API developed using lumen. I can get request using postman. But when request using Jquery.ajax it is not working. So I need to know how to enable CORS in lumen API.

回答1:

Consider creating a CorsMiddleware.php file with the following code. Find detail here.

  <?php namespace App\Http\Middleware;

    use Closure;

    class CorsMiddleware
    {
     /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        $headers = [
            'Access-Control-Allow-Origin'      => '*',
            'Access-Control-Allow-Methods'     => 'POST, GET, OPTIONS, PUT, DELETE',
            'Access-Control-Allow-Credentials' => 'true',
            'Access-Control-Max-Age'           => '86400',
            'Access-Control-Allow-Headers'     => 'Content-Type, Authorization, X-Requested-With'
        ];

        if ($request->isMethod('OPTIONS'))
        {
            return response()->json('{"method":"OPTIONS"}', 200, $headers);
        }

        $response = $next($request);
        foreach($headers as $key => $value)
        {
            $response->header($key, $value);
        }

        return $response;
    }
}

After saving it in your middleware folder, enable it by adding it to your bootstap/app.php file, on the list of you middleware like this

$app->middleware([
    ...
    App\Http\Middleware\CorsMiddleware::class // Add this

]);

I hope it helps.

I'd recommend using the CORS package by Barry vd. Heuvel: https://github.com/barryvdh/laravel-cors#lumen

It has configurable and supports Pre-flight request handling for ajax.
