I have a step that calls a remote URL successfully using the httpRequest step but, I don’t know how to use the body that is returned.
I have set logResponseBody: true but I don’t get any output of the body in the console log.
Solution:
httpRequest plugins returns a response object that exposes methods like e.g.
Stirng getContent() – response body as Stringint getStatus() – HTTP status code
You can use JsonSlurper class to parse your response to a JSON object (if the response you are getting back from the request is JSON type). Consider following exemplary pipeline:
import groovy.json.JsonSlurper
pipeline {
agent any
stages {
stage('Build') {
steps {
script {
def response = httpRequest 'https://dog.ceo/api/breeds/list/all'
def json = new JsonSlurper().parseText(response.content)
echo "Status: ${response.status}"
echo "Dogs: ${json.message.keySet()}"
}
}
}
}
}
In this example we are connecting to open JSON API (https://dog.ceo/api/breeds/list/all) and we display with echo method two things: HTTP status and a list of all dogs in this JSON response. If you run this pipeline in Jenkins you will see something like that in the console log:
[Pipeline] node
Running on Jenkins in /var/jenkins_home/workspace/test-pipeline
[Pipeline] {
[Pipeline] stage
[Pipeline] { (Build)
[Pipeline] script
[Pipeline] {
[Pipeline] httpRequest
HttpMethod: GET
URL: https://dog.ceo/api/breeds/list/all
Sending request to url: https://dog.ceo/api/breeds/list/all
Response Code: HTTP/1.1 200 OK
