发布到在笔记本电脑上运行的Mosquitto代理

Question

我已按照以下链接中列出的步骤在我的笔记本电脑上安装并运行Mosquitto代理。 https://sivatechworld.wordpress.com/2015/06/11/step-by-step-installing-and-configuring-mosquitto-with-windows-7/ 我使用命令行测试了发布和订阅事件，即mosquitto_pub和mosquitto_sub命令，它们工作正常！
我想发布到我的笔记本电脑上运行的这个代理（使用netstat-an命令监听端口1883），使用Arduino，它正在使用＆＃34; PubSubClient＆＃34;库。
对于Arduino Publish草图中服务器的IP地址，我已经给出了笔记本电脑本身的IP地址，它在连接到我的家庭网络时得到了。以下是发布商代码：

#include <SPI.h>
#include <Ethernet.h>
#include <PubSubClient.h>


#define CLIENTID "Arsen"
const char topic[] = "tem";
#define POLLINTERVAL 120000

void callback(char* topic, byte* payload, unsigned int length){
//Do nothing as we are publishing ONLY.
}

byte mac [] = {0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED} ;
IPAddress server(192, 168, 0, 10);
EthernetClient ethClient;
PubSubClient arduinoClient(server,1883, callback, ethClient) ;
unsigned long boardTime = 0 ;
float sensedTemperature = 0;
char charTemp [6];
int connRC = 0;


void setup(void) {
Serial.begin(9600);
//Connect to the MQTT server - test.mosquitto.org
beginConnection() ;
}

//Initialise MQTT connection
void beginConnection() {
Serial.begin(9600);
Ethernet.begin(mac) ;   //using the address assigned through DHCP
do{ 
int connRC = arduinoClient.connect(CLIENTID);
}while(connRC==1);
Serial.println("We are connected finally");
delay(5000);
Serial.println(arduinoClient.state());
}



void loop(void) {
boardTime = millis();
if ((boardTime % POLLINTERVAL) == 0) {
  getTemp();
  dtostrf(sensedTemperature,5,2,charTemp);
  boolean rec = arduinoClient.publish(topic, charTemp);
  Serial.println(rec);
  Serial.println("Successfully published");
}
arduinoClient.loop();
}

void getTemp() {
// Send the command to get temperatures
delay(100);
sensedTemperature = analogRead(2);   //temperature sensor at analog pin 2 on Arduino.
Serial.println(sensedTemperature);
delay(150);
}

订户代码为：

    #include <Ethernet.h>
#include <EthernetUdp.h>
#include <EthernetServer.h>
#include <EthernetClient.h>
#include <Dns.h>
#include <Dhcp.h>
#include <SPI.h>
#include <PubSubClient.h>

#define PIN 13

//MQTT Definition

#define CLIENTID "Aract"
#define TOPICNAME "tem"
byte mac [] = {0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED} ;
IPAddress server(192,168,0,5);     // Mosquitto Server
int connRC = 0;

//Handle message from mosquitto and set LEDs
void callback(char* topic, byte* payload, unsigned int length) {
int i=0; char buffer [length];
for(i=0;i<length;i++) {
  buffer [i] = char((payload[i]));
}
String payLoadData = buffer;
Serial.println(payLoadData);
setled(payLoadData);
}

//Our MQTT client
EthernetClient ethclient;
PubSubClient arduinoClient(server, 1883, callback, ethclient) ;
void setup() {
//Connect to the MQTT server - test.mosquitto.org
beginConnection() ;
}

//Initialise MQTT connection
void beginConnection() {
Serial.begin(9600);
Ethernet.begin(mac) ;
do{
connRC = arduinoClient.connect(CLIENTID) ;
delay(2000);
}while(connRC==1);
delay(3000);
Serial.println(arduinoClient.state());
if (connRC==1) {
boolean rec = arduinoClient.subscribe(TOPICNAME) ;
Serial.println(rec);
Serial.println("Successfully Subscribed");
} else {
Serial.println("connRC") ;
}
}

void loop()
{
  arduinoClient.loop() ;

}

void setled(String s)
{
  int temperature;
  temperature = s.toInt();
  Serial.println(temperature);
  if (temperature >= 200){
    digitalWrite(PIN, HIGH);
  }
  else{
    digitalWrite(PIN, LOW);
  }
}

以太网屏蔽在成功执行示例程序时运行良好。状态函数返回＆＃34;零＆＃34;这意味着电路板正在连接到网络。但是，publish命令返回一个布尔值＆＃34; rec＆＃34;这是假的。我想知道为什么这个过程一直都不成功？
verbose选项（-v）以及命令行上的Mosquitto会抛出未知错误，而不是显示已记录的详细信息。如何克服这个问题或我的技术究竟出了什么问题？

我遇到了同样的问题，我得到了解决方案...... 只需转到PC中运行的服务并停止 mosquitto-broker ，现在打开cmd并将目录更改为mosuitto所在的位置文件被定位（在我的情况下是＆＃34; cd C：\ Program Files（x86）\ mosquitto ＆＃34;）然后输入此命令 mosquitto -v ，现在刚刚离开那个窗口（如果你关闭那么它就不会工作）...... 它确实起作用，之所以它之前没有工作的原因是，当我们启动moquitto-broker服务然后它不是IPv4的开放端口时，这里是参考＆＃34; Mosquitto Error＆＃34;
