Status

This SDK currently supports the following versions of CloudEvents:

• v1.0

Installation

Install the SDK using Composer:

composer require cloudevents/sdk-php

Create a CloudEvent

use CloudEvents\V1\CloudEvent;
use CloudEvents\V1\CloudEventImmutable;

// Immutable CloudEvent
$immutableEvent = new CloudEventImmutable(
 '1n6bFxDMHZFChlI4TVI9tdzphB9',
 '/examples/php-sdk',
 'com.example.type',
 ['example' => 'first-event'],
 'application/json'
);

// Mutable CloudEvent
$mutableEvent = new CloudEvent(
 '1n6bFxDMHZFChlI4TVI9tdzphB9',
 '/examples/php-sdk',
 'com.example.type',
 ['example' => 'first-event'],
 'application/json'
);

// Create immutable from mutable or via versa
$event = CloudEventImmutable::createFromInterface($mutableEvent);
$event = CloudEvent::createFromInterface($immutableEvent);

Serialize/Deserialize a CloudEvent

use CloudEvents\Serializers\JsonDeserializer;
use CloudEvents\Serializers\JsonSerializer;

// JSON serialization
$payload = JsonSerializer::create()->serializeStructured($event);
$payload = JsonSerializer::create()->serializeBatch($events);

// JSON deserialization
$event = JsonDeserializer::create()->deserializeStructured($payload);
$events = JsonDeserializer::create()->deserializeBatch($payload);

Marshal/Unmarshal a CloudEvent

use CloudEvents\Http\Marshaller;
use CloudEvents\Http\Unmarshaller;

// Marshal HTTP request
$request = Marshaller::createJsonMarshaller()->marshalStructuredRequest($event);
$request = Marshaller::createJsonMarshaller()->marshalBinaryRequest($event);
$request = Marshaller::createJsonMarshaller()->marshalBatchRequest($events);

// Marshal HTTP response
$request = Marshaller::createJsonMarshaller()->marshalStructuredResponse($event);
$request = Marshaller::createJsonMarshaller()->marshalBinaryResponse($event);
$request = Marshaller::createJsonMarshaller()->marshalBatchResponse($events);

// Unmarshal HTTP message
$events = Unmarshaller::createJsonUnmarshaller()->unmarshal($message);

Testing

You can use composer to build and run test environments when contributing.

$ composer run -l

scripts:

 sa Run the static analyzer
 tests Run all tests locally
 tests-build Build containers to test against supported PHP versions
 tests-docker Run tests within supported PHP version containers

Community

• There are bi-weekly calls immediately following the Serverless/CloudEvents call at 9am PT (US Pacific). Which means they will typically start at 10am PT, but if the other call ends early then the SDK call will start early as well. See the CloudEvents meeting minutes to determine which week will have the call.
• Slack: #cloudeventssdk channel under CNCF's Slack workspace.

• Contact for additional information: Denis Makogon (@denysmakogon on slack).

Each SDK may have its own unique processes, tooling and guidelines, common governance related material can be found in the CloudEvents community directory. In particular, in there you will find information concerning how SDK projects are managed, guidelines for how PR reviews and approval, and our Code of Conduct information.

If there is a security concern with one of the CloudEvents specifications, or with one of the project's SDKs, please send an email to cncf-cloudevents-security@lists.cncf.io.
