HTTPBuilder adds valuecount,strings, bytes into request body and the other side can't parse that JSON

Question

I need to send request with groovy HTTPBuilder, here is code:

String authToken = "token" def cfManager = ComponentAccessor.getCustomFieldManager() def addressJira = "http://xxx" def http = new HTTPBuilder("${address}") http.setClient(HttpClients.custom().setDefaultRequestConfig(defaultRequestConfig).build()) try { http.request(POST, ContentType.JSON) { headers.'Authorization' = "token ${authToken}" headers.'Content-Type' = 'application/json' headers.'cache-control' = 'no-cache' body = [ "request": [ "token":"${authToken}", "commonData":[ "taskId":"${issue.id.toString()}" ], "phonesData":[ "phone":"${cfManager.getCustomFieldObject("customfield_xxx")?.getValue(issue)?.toString()}", "phoneType": 1 ], "addData": [ "title":"${issue.summary.toString()}", "description":"${issue.description.toString()}" ] ] ] requestContentType = ContentType.JSON response.success = { resp, json -> log.info("Resp status " + resp.status.toString()) log.info("JSON ${json.toString()}") log.info("JSON text ${json.text}") } response.failure = { resp -> log.warn("response code is : " + resp.status.toString()) log.warn("response is : " + resp.getEntity().getContent().getText()) } } } catch (Exception e) { log.warn("Exceptiion while request" + e) }

I get resp code 200 but on the other side they get JSON like this and can't parse it because of "valueCount", "strings" and "bytes":

{ "request": { "token": { "valueCount": 1, "strings": ["", ""], "bytes": [85, 69, 108, 112, 108, 120, 90, 99, 113, 107, 100, 106, 71, 108, 121, 102, 199, 115, 103, 107, 33, 45, 109, 70, 37, 65, 91, 33, 47, 77, 54, 83, 111, 115, 77, 49, 77, 50, 107, 74, 65, 122], "values": ["token"] }, "commonData": { "taskId": { "valueCount": 1, "strings": ["", ""], "bytes": [48, 49, 55, 56, 56], "values": ["here is issue id"] } }, "phonesData": { "phone": { "valueCount": 1, "strings": ["", ""], "bytes": [43, 53, 54, 55, 56, 57, 48], "values": ["+01234567890"] }, "phoneType": 1 }, "addData": { "title": { "valueCount": 1, "strings": ["", ""], "bytes": [84, 101, 115, 116], "values": ["Test"] }, "description": { "valueCount": 1, "strings": ["", ""], "bytes": [-113, -48, -78, -48, -70, -48, -80, 32, -48, -76, -48, -69, -47, -113, 32, -48, -102, -48, -90, 32, -48, -98, -48, -73, -48, -66, -48, -67, 46], "values": ["here is issue summary"] } } } }

So the question is why they get that parameters and what I have to do not to send that "valueCount", "strings" and "bytes"? Thanks to any help

Have you tried with e.g. "${issue.summary}".toString() instead? — cfrick

What @cfrick said + you might want to try that on all the GString values in the json structure. Once you write "${something}", the resulting object will be of class GString which seems to mess up the json serialization. — Matias Bjarland

That's what i meant: the toString() forces a string (and toString inside the var of a Gstring is useless anyway). — cfrick

do NOT use string interpolation here. Instead of "taskId":"${issue.id.toString()}" use "taskId":issue.id — injecteer

The serializer in some versions of Camel does not recognise GString type. Hence, you would need to force conversion to string by calling toString()

def v_stringvar = "${var1} text ${var2}";

And then you use it in this way

v_stringvar?.toString()
