Rails: How to send a json object to a other server?

Question

Hi everybody,

I'm trying to implement the in App purchase mechanism in my iPhone app. To do so I need to make a json object out of the receipt string on my rails server, and send it to a iTunes server.

• How can I create a json object out of a string? to_json didn't work for me...
• How can I send that json object to the specified Server and wait for the request...

Thanks Maechi

Answer 1

You asked: How can I create a json object out of a string?

Is your string already in json format? If so, just send it along.

You'd use to_json when you have an object that you want to auto-turn into json. Example:

class InAppPurchase
  attr_accessor :whatever, :whatever_x_two
end

purchase = InAppPurchase.new
purchase.whatever = "oh hai"
purchase.whatever_x_two = "good day"

purchase.to_json

Will output: {"whatever":"oh hai","whatever_x_two":"good day"}

You have to generate the "purchase request" from the iPhone and not the server. check out http://developer.apple.com/iphone/library/documentation/NetworkingInternet/Conceptual/StoreKitGuide/APIOverview/OverviewoftheStoreKitAPI.html#//apple_ref/doc/uid/TP40008267-CH100-SW1 for more details.
