I am using Laravel, I got [] when tried $request->all(), below when I dump( $request->getContent() );
dump
Seems like I need to remove "" from beginning and end of request in order to json_decode(), but no matter what string function I used - preg_replace, substring, etc - nothing changed, when I tried $content[0] I got { and NOT ", $content[-1] I got \n, $content[-2] I got }
Can anybody point out where I erred ?

Answer 1

Looks like this is the Content-Type header problem. But it should be a proper solution:
$find = ['/"""/', '/\\\n/', '/“/', '/”/'];
$replace = ['', '', '"', '"'];
$output = preg_replace($find, $replace, $your_input);
// now the $output is ready to be decoded
$decoded = json_decode($output);
$v = var_dump($decoded);
