How do I use groovy to create a json array? - json

Question

Example (thought of) taken from groovy ws-lite git hub project.
Say I have the following code block to send a RESTful post request:
void 'Holiday Service get holidays by country, year and month'() {
given:
def client = new RESTClient('http://www.holidaywebservice.com/HolidayService_v2/HolidayService2.asmx')
when:
def response = client.post(path: '/GetHolidaysForMonth') {
type ContentType.JSON
json files: ['spec_test.txt':[content: "2014-12-12"]]
}
then:
200 == response.statusCode
'text/xml' == response.contentType
'Christmas' == response.xml
.Holiday
.find { it.HolidayCode.text() == 'CHRISTMAS-ACTUAL'}
.Descriptor.text()
}
Here is what's generated in the request body:
{"files":{"spec_test.txt":{"content":"2014-12-12"}}}
How can I change the code to generate this json array instead:
[{"files":{"spec_test.txt":{"content":"2014-12-12"}}}]
Note the following code can do the trick:
def sampleRequest = '[{"files":{"spec_test.txt":{"content":"2014-12-12"}}}]'
def jsonArray = new JsonSlurper().parseText( sampleRequest )
void 'Holiday Service get holidays by country, year and month'() {
given:
def client = new RESTClient('http://www.holidaywebservice.com/HolidayService_v2/HolidayService2.asmx')
when:
def response = client.post(path: '/GetHolidaysForMonth') {
type ContentType.JSON
json jsonArray
}
then:
200 == response.statusCode
'text/xml' == response.contentType
'Christmas' == response.xml
.Holiday
.find { it.HolidayCode.text() == 'CHRISTMAS-ACTUAL'}
.Descriptor.text()
}
But I want to know if there is another way to do this?

Answer 1

As far as I understood well You just need to replace the following line:
files: ['spec_test.txt':[content: "2014-12-12"]]
with this one:
[[files: ['spec_test.txt':[content: "2014-12-12"]]]]
It just passed a list instead of map to json key, but double square brackets are needed because one pair will be used to indicate a map and the second one to create a list.
