CORS error despite enable it in a middleware

1

Hi,

I’m trying to update an old project and I’m having a problem with CORS.

Yet I’m using middleware that adds the right headers as explained in @odan ebook.

But it doesn’t work and the headers aren’t added at the end of the response. As if they were deleted after the middleware.

There is the code : LaBaude32 / pvappcore-test · GitLab

Does anyone have any idea what the problem is?

Thx !

Hi, should you not set the headers for the preflight response?

 if ($request->getMethod() === 'OPTIONS') {
     return $this->responseFactory->createResponse();
}

It looks like a bug in the eBook. I will fix it as soon as possible.

To add the preflight response CORS headers, change:

if ($request->getMethod() === 'OPTIONS') {
    return $this->responseFactory->createResponse();
}

to

if ($request->getMethod() === 'OPTIONS') {
    $response = $this->responseFactory->createResponse();
}
