recMess.payload.message Failed to parse Chinese about mqtt_client HOT 3 CLOSED

Ok Ill have look, do have an example payload I can use?

from mqtt_client.

_client.updates!.listen((List<MqttReceivedMessage<MqttMessage>> c) {
        final recMess = c![0].payload as MqttPublishMessage;
        final pt = MqttPublishPayload.bytesToStringAsString(recMess.payload.message);
        print('topic: ${c[0].topic}, Message: $pt');
      });

If the returned characters contain both Chinese and English, the Chinese part cannot be displayed normally

codec should be specified when converting bytes message to string, try this:

    final recMess = c![0].payload as MqttPublishMessage;
    final pt = utf8.decode(recMess.payload.message);

from mqtt_client.

Yes this is correct, only you know what your payload contains not the client, if it contains UTF8 characters you must decode it as such,.The bytesToString method you are using is a helper method for the toString method of MqttPublishPayload not a general purpose payload decoder.
