资源大小5.91M,文件格式.zip,本示例主要实现了以下三点: 1. 自建了mqtt 服务端(broker),并可以接收客户端发来的各种topic 2. 实现了客户端发布订阅mqtt消息 3. 实现了 服务端直接向外广播topic,客户端只需要 订阅该
To send messages to the broker, use the PublishAsync method of the MQTT client. Here is an example for sending messages to the broker in a loop, with one message sent every second: for (int i = 0; i < 10; i++) { var message = new MqttApplicationMessageBuilder() .WithTopic(topic...
接下来,我们创建一个简单的C控制台应用程序,用于发送和接收消息。在项目中添加以下代码: using System; using System.Text; using Mqttnet; namespace MqttnetExample { class Program { static void Main(string[] args) { // 创建一个MqttClient实例 var client = new MqttClient("mqttbroker.example.com",...
WithTcpServer("mqtt.example.com", 1883) // 替换为你的MQTT服务器地址和端口 .WithCredentials("username", "password"); // 如果需要身份验证,请提供用户名和密码 var options = optionsBuilder.Build(); mqttClient.UseDisconnectedHandler(async e => { Console.WriteLine("Disconnected from MQTT broker...
