php8.0不支持可选参数放中间了

[menglikaibin]

    function __construct(HttpClient $client, $instanceId = NULL, $topicName, $consumer, $messageTag = NULL)
    {
        if (empty($topicName)) {
            throw new InvalidArgumentException(400, "TopicName is null");
        }
        if (empty($consumer)) {
            throw new InvalidArgumentException(400, "TopicName is null");
        }

        $this->instanceId = $instanceId;
        $this->topicName = $topicName;
        $this->consumer = $consumer;
        $this->messageTag = $messageTag;
        $this->client = $client;
    }

$instanceId = NULL 这个默认值要去掉

[menglikaibin]

Required parameter $topicName follows optional parameter $instanceId会报这个错

[eoaion]

class MQProducer
function __construct(HttpClient $client, $instanceId = Null, $topicName)
需要同样去掉
