I'm working with laravel 5.5 and I came across this way of using google docs viewer:
<iframe src="https://docs.google.com/viewer?url=AQUÍ URL DEL DOCUMENTO&embedded=true" width="600" height="780" style="border: none;"></iframe>
My problem is that I do not know how I can generate or obtain a URL for my files, which I keep for the moment locally, inside the storage folder of laravel. I hope you can help me.
