PINGREQにペイロードを設定するための実行リスト

  • MqttPublishを参考にMqttPingReqpayloadフィールドを追加(最初は固定で)
  • MqttPingReqgetPayloadをオーバーライドする
  • アプリケーション内でMqttPingReqpayloadを変更できるようにする

MqttPublishpayloadフィールドをコンストラクタで設定している。そのため、MqttPingReqでも同様の実装にする。

public MqttPublish(String topic, MqttMessage message, MqttProperties properties) {
super(MqttWireMessage.MESSAGE_TYPE_PUBLISH);
this.topicName = topic;
this.payload = message.getPayload();
this.qos = message.getQos();
this.dup = message.isDuplicate();
this.retained = message.isRetained();
if (properties != null) {
this.properties = properties;
} else {
this.properties = new MqttProperties();
}
this.properties.setValidProperties(validProperties);
}

from mqttv5-client.

取り合えずcheckForActivity内でpingCommandにペイロードを付加して送信する。

public MqttPingReq(byte[] payload) {
super(MqttWireMessage.MESSAGE_TYPE_PINGREQ);
this.payload = payload;
}
