使用.net进行mqtt协议通讯,主要是为了开发居于mqtt协议向android推送消息,使用.net开发可以参考mqtt.org上面的库,我用的是M2MQTT,网上资料很少,具体例子如下:class="c#">if (this.sender == null) { this.sender = new MqttClient(IPAddress.Parse(host), 1883); //var mqttClient = new MqttClient("localhost"); this.sender.Connect("sender"); } this.sender.Publish("mobileGKTopic", System.Text.Encoding.Default.GetBytes(textBox2.Text));?二、消息接收
mqttClient = new MqttClient(IPAddress.Parse(host), 1883); //mqttClient = new MqttClient("localhost"); mqttClient.Connect("Receiver"); mqttClient.MqttMsgPublishReceived += new MqttClient.MqttMsgPublishEventHandler(mqttClient_MqttMsgPublishReceived); mqttClient.Subscribe(new string[] { "testTopic" }, new byte[] { MqttMsgBase.QOS_LEVEL_AT_LEAST_ONCE }); private void mqttClient_MqttMsgPublishReceived(object sender, uPLibrary.Networking.M2Mqtt.Messages.MqttMsgPublishEventArgs e) { //throw new NotImplementedException(); var msg = System.Text.Encoding.Default.GetString(e.Message); if (!String.IsNullOrEmpty(msg)) { textBox1.AppendText(Environment.NewLine); textBox1.AppendText(msg); } }?需要注意的是,编译mqtt库时要把条件编译SSL关闭,SSL的编译我还没有高清。
