How to parse JSON without root key - ruby-on-rails

Question

I tried searching but couldn't find any proper solution for this. I am trying to parse JSON using the RestClient gem in Ruby without a root key. When I parse it, it returns blank values.
This is the sample JSON I am trying to parse.
[
{
"id": 1,
"name": "Leanne Graham",
"username": "Bret",
"email": "Sincere#april.biz",
"address": {
"street": "Kulas Light",
"suite": "Apt. 556",
"city": "Gwenborough",
"zipcode": "92998-3874",
"geo": {
"lat": "-37.3159",
"lng": "81.1496"
}
},
"phone": "1-770-736-8031 x56442",
"website": "hildegard.org",
"company": {
"name": "Romaguera-Crona",
"catchPhrase": "Multi-layered client-server neural-net",
"bs": "harness real-time e-markets"
}
},
{
"id": 2,
"name": "Ervin Howell",
"username": "Antonette",
"email": "Shanna#melissa.tv",
"address": {
"street": "Victor Plains",
"suite": "Suite 879",
"city": "Wisokyburgh",
"zipcode": "90566-7771",
"geo": {
"lat": "-43.9509",
"lng": "-34.4618"
}
},
"phone": "010-692-6593 x09125",
"website": "anastasia.net",
"company": {
"name": "Deckow-Crist",
"catchPhrase": "Proactive didactic contingency",
"bs": "synergize scalable supply-chains"
}
}
]
I get the proper output, but when I try to access specific fields, I get blank output:
require 'rest-client'
output = RestClient.get 'https://jsonplaceholder.typicode.com/users'
puts output
puts output[0]["username"]
I get no output for username.

rest-client does not parse the JSON itself. You need to do this as an explicit step:
require 'rest-client'
response = RestClient.get('https://jsonplaceholder.typicode.com/users')
output = JSON.parse(response.body) # or just JSON.parse(response) would also work
puts output[0]["username"]
