Getting rates from an array - json -

-

i trying rates website.

so connect website = faraday.get('https://bitpay.com/api/rates')).status == 200 , try parse this.

a segment of response is:

 #<faraday::response:0x007fcf1ce25688   @env=   #<struct faraday::env   method=:get,   body=   "[{\"code\":\"btc\",\"name\":\"bitcoin\",\"rate\":1},      {\"code\":\"usd\",\"name\":\"us dollar\",\"rate\":586.66},{\"code\":\"eur\",\"name\":\"eurozone euro\",\"rate\":528.991322},{\"code\":\"gbp\",\"name\":\"pound sterling\",\"rate\":449.441986},{\"code\":\"jpy\",\"name\":\"japanese yen\",\"rate\":59907.95922},{\"code\":\"cad\",\"name\"

when website.body string class of these values found on website. want parse them though (json?) can each rate float.

i tried json.parse(website.body)["gbp"]["rate"].to_f yet again cannot work in string.

the return typeerror: no implicit conversion of string integer

i having similar (but not same) format different rates website , how handling it. need change format first or there different way around it?

you're trying access parsed json key "gbp" have array. it's if did

a = [1,2,3,4,5] a['foo']

try out

currencies = json.parse(website.body) currencies.each { |currency| puts currency['rate'] }

and change need
