c# m2mqtt 无法从服务器读取数据

[cszdlxj]

服务器用的apache apollo
publish：
static void Main(string[] args)
{
MqttClient c = new MqttClient("localhost");

string clientId = Guid.NewGuid().ToString();
c.Connect(clientId, "admin", "password");
//byte[] body = System.Text.Encoding.Default.GetBytes("/topic/testsss");
c.Publish("/topic/test", System.Text.Encoding.Default.GetBytes("让我调试出来吧！！"), MqttMsgBase.QOS_LEVEL_EXACTLY_ONCE, false);


Console.WriteLine(c.IsConnected);
Console.ReadKey();
}

subscribe:
private static string _x;
static void Main(string[] args)
{
MqttClient c = new MqttClient("localhost");
c.MqttMsgPublishReceived += mqttClient_MqttMsgPublishReceived;
string clientId = Guid.NewGuid().ToString();
c.Connect(clientId, "admin", "password");
c.Subscribe(new string[] { "/topic/test" }, new byte[] { uPLibrary.Networking.M2Mqtt.Messages.MqttMsgBase.QOS_LEVEL_EXACTLY_ONCE });

Console.WriteLine(_x);
Console.ReadKey();

}

static void mqttClient_MqttMsgPublishReceived(object sender, MqttMsgPublishEventArgs e)
{
//处理接收到的消息
string msg = System.Text.Encoding.Default.GetString(e.Message);
_x = msg;
}

需要加端口， 默认端口1883

var client = new MqttClient(brokerHostName, brokerPort, false, null, null, MqttSslProtocols.None);

apollo的tcp连接使用端口61613, var client= new MqttClient(Broker域名或者IP, 61613, false, null, null, MqttSslProtocols.None);
