I’ve try all way but without success resolve this problem
I have the following API (local) in Laravel
http://127.0.0.1:8000/api/v1/login
I’m using ionic lab
http://localhost:8200/
and show this error
Access to XMLHttpRequest at ‘http://127.0.0.1:8000/api/v1/login’ from origin ‘http://localhost:8100’ has been blocked by CORS policy: Response to preflight request doesn’t pass access control check: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.
In my service authentication
login(user: User) {
return this.http.post<User>(environment.url + '/login', user)
}
Already input proxie
"proxies": [
{
"path": "/v1",
"proxyUrl": "http://127.0.0.1:8000/api/v1"
}
]
and nothing
already input in CORS in Middleware and nothing
header('Access-Control-Allow-Origin: http://localhost:8100, http://localhost:8200');
header('Access-Control-Allow-Methods: GET, POST, PUT, PATCH, DELETE');
header('Access-Control-Allow-Headers: Origin, Content-Type, X-Auth-Token');
How to resolve it?
Add in the headers of your http requests the following

It looks like the verb for preflight is missing. CORS is only configured on the server. If you change everything to *, it should work with no problem. Once working, you can easily change the configuration to whatever your requirements are.
Hey guys, I find one solution its ok, lets go
In my case I did it in Laravel I created a file CorsMiddleware and I input the following code
app > Http > Middleware > CorsMiddleware.php
public function handle($request, Closure $next)
{
if($request->is('api/*') && \App::environment('local')) {
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: GET, POST, PUT, PATCH, DELETE');
header('Access-Control-Allow-Headers: Origin, Content-Type, X-Auth-Token, Authorization');
}
return $next($request);
}
the problem was that I had forgotten of to put in Kernel tha class CorsMiddleware like
protected $middleware = [
...
\App\Http\Middleware\CorsMiddleware::class,
];
after to make it in Ionic local work with charm, the integration with Laravel successfully now
obs: in this case, I dont’t needed to put in proxies, I removed it and work normaly
