Overview

This plugin sends a HTTP/HTTPS request to a user specified URL. The request is made via job execution in Jenkins and depending on the HTTP response the job can be marked as failed (configurable). For example, responses such as 404 and 500 can make the job fail. When a job fails it will log the response to help identify the problem.

According to the setting of HTTP mode the request will be performed either using HTTP GET or POST. If there is no such setting then it will use the default from global settings. Default there is POST.

Features

The following powerful features are available in both Pipeline and traditional project types, giving you greater control and flexibility over your builds:

Programmable HTTP method: Choose from a variety of HTTP methods, including GET, POST, PUT, PATCH, DELETE, or HEAD, to suit your project’s specific needs.
Programmable range of expected response codes: Specify a range of expected response codes for your build, and if the response code falls outside the specified range, the build will fail, saving you time and hassle.
Supports Basic Authentication: Use Basic Authentication to ensure that only authorized users can access your project’s resources, providing an additional layer of security.
Supports Form Authentication: Form Authentication enables users to authenticate themselves by submitting a username and password through a form, ensuring that only authorized users can access your resources.
Specify a required string in the response: Ensure that a specific string is present in the response by specifying it beforehand. If the string is not present, the build will fail, alerting you to the issue.
Set a connection timeout limit: Prevent builds from taking too long by setting a connection timeout limit. If the limit is exceeded, the build will fail, saving you time and resources.
Set an "Accept" header directly: Set the "Accept" header directly, providing greater control over the type of data that the server returns in response to a request.
Set a "Content-Type" header directly: Set the "Content-Type" header directly, specifying the type of data that you are sending in your request, helping to ensure that the server can correctly process your request.
Set any custom header: Set any custom header that you require, enabling you to interact with APIs or web services that require specific headers or authentication protocols.

Basic plugin features

ℹ️	Feature Availability The following features are only present in the non-pipeline version of the plugin. For the Pipeline version, these features are available programmatically.

You can send the build parameters as URL query strings
You can store the response to a file, built-in to the plugin

Pipeline features

In a Pipeline job, you have total control over how the url is formed. Suppose you have a build parameter called “param1”, you can pass it to the HTTP request programmatically like so:

httpRequest "http://httpbin.org/response-headers?param1=${param1}"

If you wish to save the response to a file, you need to grab a workspace. You can do this with a node Pipeline step. For example:

def response = httpRequest "http://httpbin.org/response-headers?param1=${param1}"
node() {
    writeFile file: 'response.txt', text: response.content
}

You can access the response status code, content and headers programmatically:

def response = httpRequest "http://httpbin.org/response-headers?param1=${param1}"
println("Status: ${response.status}")
println("Response: ${response.content}")
println("Headers: ${response.headers}")

You may also send content in the body of the request, such as for a PATCH request:

// create payload
def patchOrg = """
    {"description": "$description"}
"""
def response = httpRequest acceptType: 'APPLICATION_JSON', contentType: 'APPLICATION_JSON',
                           httpMode: 'PATCH', requestBody: patchOrg,
                           url: "https://api.github.com/orgs/${orgName}"

You may also send content in the body of the request, such as for a POST request:

httpRequest acceptType: 'APPLICATION_JSON', contentType: 'APPLICATION_JSON',
            httpMode: 'POST', quiet: true,
            requestBody: '''{
               "display-name" : "my_Username",
               "email" : "[email protected]",
               "password" : {
                  "value" : "my_password"
               },
            }''',
            url: 'https://api.github.com/orgs/${orgName}'

You can also set custom headers:

def response = httpRequest customHeaders: [[name: 'foo', value: 'bar']]

You can also set custom headers with mask set true:

def response =  httpRequest customHeaders: [[maskValue: true, name: 'foo', value: 'bar']],
                            url: 'https://api.github.com/orgs/${orgName}'

You can send multipart/form-data forms:

def response = httpRequest httpMode: 'POST', formData: [
               [contentType: 'application/json', name: 'model', body: '{"foo": "bar"}'],
               [contentType: 'text/plain', name: 'file', fileName: 'readme.txt',
               uploadFile: 'data/lipsum.txt']]

You can send a request with form-data:

def response = httpRequest acceptType: 'APPLICATION_JSON', contentType: 'APPLICATION_FORM_DATA',
                           formData: [[body: '''{
                                         "name" : "example",
                                         "type" : "bot"
                                        }''',
                           contentType: 'text/plain', fileName: 'sample', name: 'data',
                           uploadFile: './files/readme.txt']],
                           httpMode: 'POST', quiet: true, responseHandle: 'NONE', timeout: null,
                           url: 'https://api.github.com/orgs/${orgName}',
                           validResponseCodes: '200,404', validResponseContent: 'token'

You can send multipart file and multipart entity name:

def response = httpRequest acceptType: 'APPLICATION_JSON', contentType: 'APPLICATION_OCTETSTREAM',
                           httpMode: 'POST', multipartName: 'file', quiet: true,
                           responseHandle: 'NONE', timeout: null, uploadFile: './files/readme.txt',
                           url: 'https://api.github.com/orgs/${orgName}'

You can send a request with SSL error ignored

def response = httpRequest ignoreSslErrors: true, responseHandle: 'NONE',
                           url: 'https://api.github.com/orgs/${orgName}'

You can send a request with http proxy

def response = httpRequest httpProxy: 'http://proxy.local', responseHandle: 'NONE',
                           url: 'https://api.github.com/orgs/${orgName}'

You can send a request with http proxy authenticate

def response = httpRequest httpProxy-authenticate: Basic, 'http://proxy.local',
               responseHandle: 'NONE', url: 'https://api.github.com/orgs/${orgName}'

You can send a request with accepted response codes

def response = httpRequest responseHandle: 'NONE', validResponseCodes: '200,404',
                           url: 'https://api.github.com/orgs/${orgName}'

You can send a request with accepted response content

def response = httpRequest responseHandle: 'STRING',
                           url: 'https://api.github.com/orgs/${orgName}',
                           validResponseCodes: '200,404', validResponseContent: 'token'

You can send a request with connection timeout

def response = httpRequest timeout: 30, url: 'https://api.github.com/orgs/${orgName}'

You can send a request where output is written to file

def response = httpRequest outputFile: 'readme.txt', url:'https://api.github.com/orgs/${orgName}'

You can send a request where response is printed on the console

def response = httpRequest consoleLogResponseBody: true,
               url:'https://api.github.com/orgs/${orgName}'

You can send a request without logging output — with logs turned off

def response = httpRequest quiet: true, url:'https://api.github.com/orgs/${orgName}'

You can handle response

def response = httpRequest responseHandle: 'LEAVE_OPEN',
                           url: "https://api.github.com/orgs/${orgName}"
response.close() // must call response.close() after a LEAVE_OPEN

You can use a Jenkins credential to authenticate the request

def response = httpRequest authenticate: 'my-jenkins-credential-id',
                           url: 'https://api.github.com/user/jenkinsci'

For details on the Pipeline features, use the Pipeline snippet generator in the Pipeline job configuration.

⚠️	Known Limitations If Jenkins is restarted before the HTTP response comes back, the build will fail.

Building

The plugin can be built and tested locally using a Maven Docker container:

docker run -it --rm -v "$(pwd)":/usr/src/mymaven -w /usr/src/mymaven maven:3.3-jdk-8 mvn test

HTTP Request Parameters

Parameters are escaped, which means if you try to pass another value inside a value, it will not happen.

In the example below, the key “name” will be passed with a value of “jenkins&os=linux”. Note that “os” is not a parameter - it is part of the value). At the HTTP server-side no parameter named “os” will exist.

🔥	Regarding Logging & Sensitive Information Every execution will log all parameters. Be careful to not pass private information such as passwords or personal information.
