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.
