Laravel Currency Conversion - Quick workaround

Currency.php

        $response = \Http::get($url);
        if (!$response->successful()) {
            return null;
        }
        $key = "{$this->from}.{$this->to}";

        $data = $response->json();
        cache()->put("currency.$key", $data, now()->addDay()->startOfDay());
        cache()->put("currency.long.$key", $data, now()->addDays(30));

        return $data;
    }
}

One of the currency conversion packages I was using stopped working. Here is a quick hack to get things working for the convert() functionality OG Package: amrshawky/laravel-currency#19

Just wanted to say THANK YOU! This saved me tons of time and was very easy to implement. Cheers 😄

Thanks for the code.

I made some updates, since the https://github.com/fawazahmed0/currency-api was migrate to https://github.com/fawazahmed0/exchange-api
