Make an HTTP by creating a new HTTP instance.
Request the data passing the respective method, the content type, and the request configuration closure to the request method.
Return the parsed data from the response.

Snippet

import groovyx.net.http.HTTPBuilder
import static groovyx.net.http.Method.<methodName>
import static groovyx.net.http.ContentType.<contentType>
 
// initialize a new builder and give a default URL
def http = new HTTPBuilder("<URL>")
 
def data = http.request(<methodName>,<contentType>) { req ->
 
  response.success = { resp, reader ->
    assert resp.status == 200
	return reader
  }
 
  // called only for a 404 (not found) status code:
  response."404" = { resp ->
    log.error ("Not found")
  }
}

if (data) {
  // process returned data
}

Example

To get the HTML text an issue view page, you can use this snippet to make the HTTP call, get the content and parse it.

import groovyx.net.http.HTTPBuilder
import static groovyx.net.http.Method.GET
import static groovyx.net.http.ContentType.TEXT
 
// initialize a new builder and give a default URL
def http = new HTTPBuilder("https://www.google.com/")
 
return http.request(GET,TEXT) { req ->
  response.success = { resp, htmlText ->
    assert resp.status == 200
    log.debug("My response handler got response: ${resp.statusLine}")
    if(htmlText){
     return htmlText.getText()
    }
    else{
      return null
    }
  }
 
  // called only for a 404 (not found) status code:
  response."404" = { resp ->
    log.error ("Not found")
    return null
  }
}
