Hi,

I need to map GitHub user ID to Jira email address (and vice versa). I want to keep the mapping in an external service that provides a couple endpoints I can call via an https link. How do I make such a call in the exalate sync configuration scripts?

Hi,

We are looking into include a groovy HttpBuilder into the script context but at the moment, you can rely on the native groovy way (found on https://stackoverflow.com/questions/25692515/groovy-built-in-rest-http-client)

// GET
def get = new URL("https://httpbin.org/get").openConnection();
def getRC = get.getResponseCode();
println(getRC);
if(getRC.equals(200)) {
    println(get.getInputStream().getText());
}

// POST
def post = new URL("https://httpbin.org/post").openConnection();
def message = '{"message":"this is a message"}'
post.setRequestMethod("POST")
post.setDoOutput(true)
post.setRequestProperty("Content-Type", "application/json")
post.getOutputStream().write(message.getBytes("UTF-8"));
def postRC = post.getResponseCode();
println(postRC);
if(postRC.equals(200)) {
    println(post.getInputStream().getText());
}
