大文件的Laravel Dropzone TokenMismatchException

I have a Laravel application and a form with dropzone. Normally , it works well. But when i try to upload large files ( 50M - 60 M), I get this error TokenMismatchException.

I'm using this code to send token :

formData.append("_token", $('[name=_token]').val());

I also changed all php.ini settings:

• max_upload_size
• set_time_limit(0);
• memory_limit
• post_max_size
• max_input_time

As said above, it's working for small files.

I solved the issue. It's because of php.ini file. I edited and saved php.ini but it didn't effect the output of phpinfo(); function. Output was showing old values. Check this link for solution :

Changes to upload_max_filesize in Ubunutu php.ini will not take effect

If you have changed all the php settings, that should not be an issue. However, if this is being done over AJAX, then appending a _token to the request is messy and hacky. Instead, set the {{ csrf_token }} as your request header. More specifically, set it on the X-CSRF-TOKEN header, since Laravel checks for that in the middleware.
