Convert payload to json in laravel - development

Convert payload to json in laravel

I get a form data in Laravel

$request->getContent();

Result is:

"""
------WebKitFormBoundaryNBoGTqDMmoBbVxmNrn
Content-Disposition: form-data; name="avatar"rnrn data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAA...AAABBESAIAgQgIAEERIAACCCAkAQBAhA   QAIIiQAAEGEBAAg4H//+z90ysSjp0MzewAAAABJRU5ErkJggg==rn------WebKitFormBoundaryNBoGTqDMmoBbVxmN--rn"""

How can I parse it to json in laravel?
