Another issue when trying to POST JSON to REST URL via HttpBuilder - json

Question

I read this and several other postings on SO and elsewhere about how to send a Post call via HttpBuilder with JSON as the data content. My problem is that NONE OF THOSE SOLUTIONS are working!
My problem is only slightly different. I have existing JSON data in a file. When I attempt to send this to the REST interface with curl:
curl -X POST -u "username:password" -d #/path/to/myFile.json http://localhost:8080/path/here --header "Content-Type:application/json"
all works perfectly well. Here is where I am at (some extra code IS in there, read on):
def myFile = new File('/path/to/myFile.json')
if (!myFile.exists()) println "ERROR! Do not have JSON file!"
def convertedText = myFile.text.replaceAll('\\{', '[')
convertedText = convertedText.replaceAll('\\}', ']')
def jsonBldr = new JsonBuilder()
jsonBldr myFile.text
println jsonBldr.toString()
def myClient = new groovyx.net.http.HTTPBuilder('http://username:password#localhost:8080/my/path')
myClient.setHeaders(Accept: 'application/json')
results = myClient.request(POST, JSON) { req ->
body = [ jsonBldr.toString() ]
requestContentType = JSON
response.success = { resp, reader ->
println "SUCCESS! ${resp.statusLine}"
}
response.failure = { resp ->
println "FAILURE! ${resp.properties}"
}
}
This results in the 'failure' closure with this data:
statusLine:HTTP/1.1 400 Exception evaluating property 'id' for java.util.ArrayList, Reason: groovy.lang.MissingPropertyException: No such property: id for class: java.lang.String
FWIW, there is no "id" in my JSON anywhere. If I change the "body" line from "[ jsonBldr.toString() ]" to "[ convertedText ]" - which is why that code is up there, I get the same error. If I take out the brackets on the body, I get an error stating that the body is not data for an array (as its a Map).
Can anyone (far groovier than I) tell me what the %%$## I am doing wrong???

You need JsonSlurper instead of JsonBuilder. After which the implementation would look like:
def myFile = new File('/path/to/myFile.json')
if (!myFile.exists()) println "ERROR! Do not have JSON file!"
def bodyMap = new JsonSlurper().parseText(myFile.text)
def myClient = new groovyx.net.http.HTTPBuilder('http://username:password#localhost:8080/my/path')
modelClient.setHeaders(Accept: 'application/json')
results = myClient.request(POST, JSON) { req ->
requestContentType = JSON
body = bodyMap
response.success = { resp, reader ->
println "SUCCESS! ${resp.statusLine}"
}
response.failure = { resp ->
println "FAILURE! ${resp.properties}"
}
}
However, I am not clear what is difference between myFile and modelFile in your code.
