Reading a JSON key that has a hyphen in it?

[bptworld]

I've come across a Json file that contains a key that has a hypen in it. I've done tons of searching on Google but can't figure out how to read this.

Example Json:
"country_name":"United States",
"iso-3166":"US",
etc...

I can read the 'counry_name' just fine. But the 'iso-3166' is throwing an error because it thinks it's a minus sign.

Here's an example of the code I'm using... I've tried many ways of getting the iso value with no luck. This is just the latest attempt.

httpGet(params) { resp ->
  def json = resp.data
   for (rec in json.response.countries) {
          cName += "$rec.country_name ($rec.['iso-3166'])"
   } 
}

Desired output is 'United States (US)'

Appreciate any help!

Shot in the dark here. Have you tried double-quotes around iso-3166 instead of single-quotes?

So [“iso-3166”]?

I got it!

       httpGet(params) { resp ->
            def json = resp.data
            for (rec in json.response.countries) {
                iso = rec['iso-3166']
                cName += "$rec.country_name ($iso)"
            } 
        }

I was soo close! lol
