REST - JSON request

Here's a sample JSON request:  Sample1 comes with an attribute Type and it's empty. Is it possible if the attribute is empty. Can this be removed like the output on sample2. I tried to use the remove empty content and set it true which I usually did on XML. However, it seems like this does not apply do JSON request message.  I am not sure if there's a way around this.

 

Sample 1:

        "Transfer" : {
            "Service" : "Mix",
            "Instruct" : {
                "Account" : {
                    "Number" : "xx8172121",
                    "Type" : "",
                    "Prod": "NEW"
                }
   }
  }   

 

Sample 2:

        "Transfer" : {
            "Service" : "Mix",
            "Instrucy" : {
                "Account" : {
                    "Number" : "xx8172121",
                    "Prod": "NEW"
                }
   }
  }

    You can do this with JsonSlurper and JsonBuilder

     

    import groovy.json.*

// Deserialize JSON into generic map
def obj = new JsonSlurper().parseText(Sample1)

// Remove Type
obj.getAt("Transfer").getAt("Instruct").getAt("Account").remove("Type")

// Serialize back to Json
String json = new JsonBuilder(obj).toString()

    This does assume that the structure of these objects will always be the same. If that is not the case, you would need to iterate the map.

      Thanks for the input. When you say Sample1 do you mean an input file or a REST (POST message ) like something shown below. As I do need to pull out data from the Excel data sheet.

       

      {
        "Transfer": {
          "Service": "${#Project#service}",
          "Instruct": {
            "Account": {
              "Number": "${#Project#Number}",
              "Type": "",
              "Prod": "${#Project#Prod}"
            }
          }
        }
      }

        Yes, so:

         

        import groovy.json.*

        String sample1 = '{"Transfer": {"Service": "${#Project#service}","Instruct": {"Account": {"Number": "${#Project#Number}","Type": "","Prod": "${#Project#Prod}"}}}}'

        // Deserialize JSON into generic map
def obj = new JsonSlurper().parseText(sample1)

// Remove Type
obj.getAt("Transfer").getAt("Instruct").getAt("Account").remove("Type")

// Serialize back to Json
String json = new JsonBuilder(obj).toString()

         

        Now where you get sample1 from depends on your test, whether you're pulling it from an Excel sheet or directly from the response of a REST request.
