【项目自荐】Apache Pulsar Client for PHP

[ikilobyte]

• 项目地址：https://github.com/ikilobyte/pulsar-client-php

• 类别：PHP

• 项目标题：PHP Native Client library for Apache Pulsar

• 项目描述：由于Pulsar官方未提供PHP客户端，php开发者使用pulsar时很不方便，所以开发了这个纯PHP实现的客户端，方便php开发者使用

• 示例代码：依据Pulsar.proto实现

Producer

<?php

use Pulsar\Authentication\Jwt;
use Pulsar\Compression\Compression;
use Pulsar\Producer;
use Pulsar\ProducerOptions;
use Pulsar\MessageOptions;

require_once __DIR__ . '/vendor/autoload.php';

$options = new ProducerOptions();

// If permission authentication is available
// Only JWT authentication is currently supported
$options->setAuthentication(new Jwt('token')); 

$options->setConnectTimeout(3);
$options->setTopic('persistent://public/default/demo');
$options->setCompression(Compression::ZLIB);
$producer = new Producer('pulsar://localhost:6650', $options);
$producer->connect();

for ($i = 0; $i < 10; $i++) {
    $messageID = $producer->send(sprintf('hello %d',$i));
    echo 'messageID ' . $messageID . "\n";
}

// Sending messages asynchronously
//for ($i = 0; $i < 10; $i++) {
//    $producer->sendAsync(sprintf('hello-async %d',$i),function(string $messageID){
//        echo 'messageID ' . $messageID . "\n";
//    });
//}
//
//// Add this line when sending asynchronously
//$producer->wait();

// Sending delayed messages
for ($i = 0; $i < 10; $i++) {
    $producer->send(sprintf('hello-delay %d',$i),[
        MessageOptions::DELAY_SECONDS => $i * 5, // Seconds
    ]);
}

// close
$producer->close();

Consumer

<?php

use Pulsar\Authentication\Jwt;
use Pulsar\Consumer;
use Pulsar\ConsumerOptions;
use Pulsar\SubscriptionType;

require_once __DIR__ . '/vendor/autoload.php';

$options = new ConsumerOptions();

// If permission authentication is available
// Only JWT authentication is currently supported
$options->setAuthentication(new Jwt('token'));

$options->setConnectTimeout(3);
$options->setTopic('persistent://public/default/demo');
$options->setSubscription('logic');
$options->setSubscriptionType(SubscriptionType::Shared);

// Configure how many seconds Nack's messages are redelivered, the default is 1 minute
$options->setNackRedeliveryDelay(20);

$consumer = new Consumer('pulsar://localhost:6650', $options);
$consumer->connect();

while (true) {
    $message = $consumer->receive();
    echo sprintf('Got message 【%s】messageID[%s]  topic[%s] publishTime[%s]',
        $message->getPayload(),
        $message->getMessageId(),
        $message->getTopic(),
        $message->getPublishTime()
    ) . "\n";
    
    // ... 
    
    // Remember to confirm that the message is complete after processing
    $consumer->ack($message);
    
    // When processing fails, you can also execute the Nack
    // The message will be re-delivered after the specified time
    // $consumer->nack($message);
}

$consumer->close();
