一個(gè)簡單的問題，我正在使用 php-rdkafka （https://github.com/arnaud-lb/php-rdkafka）冒險(xiǎn)進(jìn)入 Kafka。我瀏覽了文檔，但找不到生成現(xiàn)有主題的語法，除非語法 newTopic 將插入到我懷疑的現(xiàn)有主題中。我不斷拋出 Java 錯(cuò)誤，而且我不擅長調(diào)試 Java 錯(cuò)誤。我正在向那些一直在使用該框架的人尋求幫助，這是正確的語法嗎？請指教<?php$conf = new RdKafka\Conf();$conf->set('metadata.broker.list', 'localhost:9092');//If you need to produce exactly once and want to keep the original produce order, uncomment the line below//$conf->set('enable.idempotence', 'true');$producer = new RdKafka\Producer($conf);$topic = $producer->newTopic("test"); // Is this a correct syntax to consume existing topic?for ($i = 0; $i < 10; $i++) {    $topic->produce(RD_KAFKA_PARTITION_UA, 0, "Message $i");    $producer->poll(0);}for ($flushRetries = 0; $flushRetries < 10; $flushRetries++) {    $result = $producer->flush(10000);    if (RD_KAFKA_RESP_ERR_NO_ERROR === $result) {        break;    }}if (RD_KAFKA_RESP_ERR_NO_ERROR !== $result) {    throw new \RuntimeException('Was unable to flush, messages might be lost!');}
