Ruby: send HTTP GET request, receive JSON output - what is the fastest way?

My application will call Facebook API multipl开发者_JAVA百科e times: the example.

What is the fastest / most reliable way to send HTTP GET requests and parse the returned output in JSON format?

Should I use Curl::Easy? If yes, how does it deal with JSON?

Use httparty

it includes crack for json. Use it like so:-

httparty "http://twitter.com/statuses/public_timeline.json"

What does "multiple times" mean? Twice? X times every n minutes? Thousands of times an hour?

Ruby has Typhoeus/Hydra, which handles huge numbers of concurrent requests. Processing the JSON is easy compared to handling multiple requests.

The Times example is a good starting point. Stick your JSON processing in the on_complete handler.
