How to make a REST API call from jenkins pipeline - jenkins

Question

I'm trying to make a REST API call from jenkins pipeline once a build job is finished. Since I'm new to the content, I'm unable to complete the build with my below script:
pipeline {
agent any
stages {
stage('BUILD') {
steps {
echo 'Demo Staging Build Running'
}
}
}
post {
always {
echo 'Demo Staging Build Completed'
echo "Build Result: ${currentBuild.result}"
echo "Build Url: ${env.BUILD_URL}"
def response = httpRequest acceptType: 'APPLICATION_JSON', httpMode: 'GET', url: 'http://localhost:9091/demo/jenkins-res'
echo "Status: ${response.status}"
}
}
}
While running the script, I'm getting the below error:
Running in Durability level: MAX_SURVIVABILITY
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 27: Expected a step # line 27, column 13.
def response = httpRequest acceptType: 'APPLICATION_JSON', httpMode: 'GET', url: 'http://localhost:9091/ucreator/jenkins-res'

Answer 1

Rectified the issue with a script tag surrounding the request
pipeline {
agent any
stages {
stage('BUILD') {
steps {
echo 'Demo Staging Build Running'
}
}
}
post {
always {
echo 'Demo Staging Build Completed'
echo "Build Result: ${currentBuild.result}"
echo "Build Url: ${env.BUILD_URL}"
script {
def response = httpRequest acceptType: 'APPLICATION_JSON', httpMode: 'GET', url: 'http://localhost:9091/demo/jenkins-res'
}
echo "Status: ${response.status}"
}
}
}
