Bit confused on how to get at my table using pairs

Solar2D Lua Language

I have a table created from a JSON string and am struggling to get at the information in it. I have read quite a few table tutorials but none seem to go deep enough.

Here is my JSON string -

{“results”:[{“offerDesc”:“30% off at whatever restaurant in town”,“offerURL”:“www. restaurant.com”},{“offerDesc”:“A bargain in liverpool”,“offerURL”:“www.anotherurl.co.uk”}]}

To get it into my table am using -

  for k,v in pairs(response) do    offers[k] = v end

But then if I go around myTable using pairs and printing the results to terminal am getting ‘table: 0x10b4c8770’

Ideally I would want to access myTable.offers like this -

offers[1].offerDesc

offers[2].offerDesc

Any ideas ?

Thats because there is a results variable inside your array.
Your format is like this
 

{
    “results” : [
      {
          “offerDesc” : “30% off at whatever restaurant in town”,
          “offerURL” : “www. restaurant.com”
      },
      {
          “offerDesc” : “A bargain in liverpool”,
          “offerURL” : “www.anotherurl.co.uk”
      }
   ]
}

So as it is now, you will have to access the results as 

offers.results[1].offerDesc

offers.results[2].offerDesc

if you want to access as offers[1].offerDesc, then your json should be
 

[{“offerDesc”:“30% off at whatever restaurant in town”,“offerURL”:“www. restaurant.com”},{“offerDesc”:“A bargain in liverpool”,“offerURL”:“www.anotherurl.co.uk”}]
