Register the CatchAllOptionsRequestsProvider service provider in bootstrap/app.php which will check the incoming request and response successfully if it is an OPTIONS request.
Add the CorsMiddleware to the $app->middleware([ array in bootstrap/app.php which will attach the following CORS headers to all responses:
Hello everyone again. I solved my error related to this issue. I share my answer with you below.
Due to the middleware structure, it returns and switches to the next request after processing. If an error is encountered after the request middleware has passed and did not return, the return value will be null.
For example, after I pass the request from the cors middleware, I am sending a mail via a event as a result of a series of operations. However, even though I changed the mail blade I sent, the cors middleware response value returns null because the php document created in ~/storage/framework/views does not update, and an error occurs.
A single file solution with CorsMiddleware.php worked like a charm with Lumen 8.x. The only issue I had that my .htaccess file was not default and was adjusted with the following command:
In my case I had to remove these lines to make things work.
