Executing Groovy script from JSON - json

Question

If I want to send multiline string in JSON using curl the only way is to concatenate string using spaces. So this is working. But what to do if I send groovy script which will be run? Like in content property:
{
"name": "helloWorld",
"content": "repository.createDockerHosted('docker_private', 8082_1, null) repository.createDockerHosted('docker_private_2', 8082, null)",
"type": "groovy"
}
Is it possible to inform groovy compiler that there are two instructions? Maybe by adding some special character to content value?
Thanks for help :)

To execute a string as Groovy script, the standard pattern is to use GroovyShell with a Binding:
class Repository {
def createDockerHosted(a, b, c) {
println "TRACER createDockerHosted $a $b $c"
}
}
def content = "repository.createDockerHosted('docker_private', 8082_1, null) ; repository.createDockerHosted('docker_private_2', 8082, null)"
def binding = new Binding()
binding.setProperty('repository', new Repository())
def shell = new GroovyShell(binding)
shell.evaluate(content)
(Note in the above that content has ; to separate the two statements) Output:
$ groovy Example.groovy
TRACER createDockerHosted docker_private 80821 null
TRACER createDockerHosted docker_private_2 8082 null
So for your situation (if I understand it), the only issue is how to extract content from JSON:
def jsonStr = '''
{
"name": "helloWorld",
"content": "repository.createDockerHosted('docker_private', 8082_1, null) ; repository.createDockerHosted('docker_private_2', 8082, null)",
"type": "groovy"
}
'''
def jsonMap = new groovy.json.JsonSlurper().parseText(jsonStr)
def content = jsonMap['content']
