You can try eval method on temp json string

Example:

eval(temp)

This will return following hash

{"accept"=>"*/*", "host"=>"localhost:4567", "version"=>"HTTP/1.1", "user_agent"=>"curl/7.22.0 (x86_64-pc-linux-gnu) libcurl/7.22.0 OpenSSL/1.0.1 zlib/1.2.3.4 libidn/1.23 librtmp/2.3", "http_token"=>"375fe428b1d32787864264b830c54b97"}

Hope this will help.

Thanks

if your parse this string to ruby object, it will return a ruby Hash object, you can get it like this You can install the json gem for Ruby

gem install json

You would require the gem in your code like this:

require 'rubygems'
require 'json'

Then you can parse your JSON string like this:

ruby_obj = JSON.parse(json_string)

There are also other implementations of JSON for Ruby:

To convert a Ruby hash to json string, simply call to_json. 

require 'json'

temp = {"accept"=>"*/*", "host"=>"localhost:4567", "version"=>"HTTP/1.1", 
   "user_agent"=>"curl/7.22.0 (x86_64-pc-linux-gnu) libcurl/7.22.0 OpenSSL/1.0.1 zlib/1.2.3.4 libidn/1.23 librtmp/2.3", 
   "http_token"=>"375fe428b1d32787864264b830c54b97"}
temp.to_json

Do you know about JSON.parse ?

require 'json'

my_hash = JSON.parse('{"hello": "goodbye"}')
puts my_hash["hello"] => "goodbye"
