Format response field as decimal number instead of string when using JsonPath.

[robertmircea]

I am using the following mapping JSON file:

{
  "Guid": "42c42a10-897e-44e1-a50c-f3662193823d",
  "Title": "XYZ",
  "Priority": 100,
  "Request": {
    "Path": {
      "Matchers": [
        {
          "Name": "ExactMatcher",
          "Pattern": "/tpcm/v1/events/oneShot"
        }
      ]
    },
    "Methods": [
      "POST"
    ],
    "Headers": [
      {
        "Name": "Content-Type",
        "Matchers": [
          {
            "Name": "WildcardMatcher",
            "Pattern": "application/json",
            "IgnoreCase": true
          }
        ]
      }
    ],
    "Body": {
      "Matcher": {
        "Name": "JsonPartialWildcardMatcher",
        "Pattern": {
          "applicationId": "*",
          "currency": "EUR",
          "msisdn": "*",
          "externalId": "*",
          "transactionDescription": "*"
        },
        "IgnoreCase": false
      }
    }
  },
  "Response": {
    "StatusCode": 200,
    "UseTransformer": true,
    "BodyAsJson": {
      "reservedAmount": "{{JsonPath.SelectToken request.bodyAsJson \"price\"}}",
      "transactionId": "{{Random type='Guid' Format='N'}}"      
    },
    "Headers": {
      "Expires": "0",
      "Content-Type": "application/json; charset=UTF-8",
      "Cache-Control": "no-store, must-revalidate, no-cache, max-age=0",
      "Pragma": "no-cache",
      "Transfer-Encoding": "chunked"
    }
  }
}

Please note the following transformation expression for "reservedAmount" field in the response: "reservedAmount": "{{JsonPath.SelectToken request.bodyAsJson \"price\"}}",

The transformer generates the following json response given that I send the following request to Wiremock standalone server:

{
  "applicationId": "ABA",
  "currency": "EUR",
  "msisdn": "07777",
  "price": 0.005,
  "externalId": "uLGpSXnsCghn",
  "transactionDescription": "ABC"
}

Response:

{
  "reservedAmount": "0,005",
  "transactionId": "6447291E73BD44A78260940456AEDB0E"
}

Two questions:

1. How can I return the reservedAmount field as JSON decimal number and not as a string?
2. How can I format the returned number with a decimal dot instead of a comma?

You don't need to use JsonPath.SelectToken, you can just access the properties from that request.bodyAsJson.

So:

"BodyAsJson": {
      "reservedAmount": "{{request.bodyAsJson.price}}",
      "transactionId": "{{Random type='Guid' Format='N'}}"      
    },

Your recommendation works but the price field is still formatted incorrectly as a string instead of a number and it uses a comma instead of a decimal dot:

{
"reservedAmount":"0,005",
"transactionId":"B1359682B67647D6A7C96C9CD8D2F37F"
}

I'll take a look.

It works! Looks good! Can you include the fix please in a nuget release?

[StefH]

Yes

I will release a new nuget soon.
