Forum: Ruby Httparty parsed response

Hi all,

I am using httparty to get the content of a service.


@reponse = httparty.get(url)

puts @reponse.parsed_response

parsed_reponse is as follows,

@parsed_response =>{"name" => "ruby", "number" => {"item"=>{"@no"=>"1",
"itemcontent"=>{"itemcategory"=>{"@itemtype"=>"Book",
"@itemtag"=>"Generak"}}, "form"=>"text", "shape"=>"square",
"dimension"=>"full", "type"=>{"category"=>{"@itemid"=>"24",
"@itemexpiry"=>"false", "@quote"=>"[FRESH]", "$"=>"2010"}},
"expiryComments"=>{"expiryStatus"=>{"@expiry"=>"true", "$"=>"2012"}}},
"shop"=>{"shopName"=>"STORE"}}}

I need to parse each and every hash and its elements and even array of
elements inside each hash

for example say,

I need to parse and equate,

name = "rub"

@parsed_response["name"].should == name

this will result
expected: rub
got: ruby

similarly, for each and every hash I need to check the value with some
other value, whether they are equal or not.

Can anyone kindly explain with code, how to parse each value of the
above response.

the above parsed response is only one such record, but i do have
multiple records to check like

@parsed_response => {"name" => "ruby", "number" => {"item"=>{"@no"=>"1",
.......}},{"item" => {"@no" = >"2", ....}},{"item" => {"@no" = >"3",
....}}}

In this case I need to check for all the values. need assistance for
this.


Thanks in advance

Can Any one Help me on this

I'm still a bit of a nube with ruby but I have been working with this 
library a little bit.
Using your example response:

def check_and_change
res=@parsed_response
name='rub'
itemtype='Book'

# if the name in your results does not equal 'rub' changes the value to 
'rub'
if res['name'] != name
  res['name']=name
end

#if the item type is 'Book' puts 'Win'

if res['number']['item']['itemcontent']['itemcatagory']['@itemtype']== 
itemtype
puts 'Win'
end

#If there are multiple 'item' records
assuming it looks like this:
> @parsed_response => {"name" => "ruby", "number" => {"item"=>{"@no"=>"1",
> .......}},{"item" => {"@no" = >"2", ....}},{"item" => {"@no" = >"3",
> ....}}}

if 
res['number'].first['item']['itemcontent']['itemcatagory']['@itemtype']== 
itemtype
puts 'first Win'
end
if 
res['number'].last['item']['itemcontent']['itemcatagory']['@itemtype']== 
itemtype
puts 'last Win'
end

Hope that makes sense and helps

The response is in standard JSON format.  Look into the JSON gem (IIRC, 
included in most default ruby installs).  The method you'll want 
specifically is "JSON.parse @reponse.parsed_response".  That will return 
the JSON data in native ruby format as hashes, arrays, strings, etc. 
From there, you can manipulate the data using those objects' methods.
