按照Jeremy Gooch的指示,参见http://goochgooch.co.uk/2014/08/01/building-mosquitto-1-4/,我将mosquitto安装在RPi上的websockets上。我可以分发/发布消息来测试网站http://test.mosquitto.org/ws.html
从那时起,我在mosquitto.conf中启用了用户和主题访问控制以进行更多测试,但奇怪的是,当我再次启动mosquitto时,我会看到每秒的套接字错误......
sudo /usr/local/sbin/mosquitto -v -c /etc/mosquitto/mosquitto.conf
1429857948: mosquitto version 1.4 (build date 2015-04-20 22:04:51+0800) starting

我修改配置文件以仅启用ACL,注释掉所有其他文件,套接字错误仍然存在。配置文件现在看起来:
sudo nano /etc/mosquitto/mosquitto.conf
autosave_interval 1800
persistence true
persistence_file m2.db
persistence_location /var/tmp/
connection_messages true
log_timestamp true
log_dest stderr
log_type error
log_type warning
log_type debug
allow_anonymous false
password_file /etc/mosquitto/mqtt.pw
acl_file /etc/mosquitto/mqtt.acl
port 1883
protocol mqtt
我甚至测试使用示例password_file和acl_file,但是同样的错误。 在谷歌搜索,也没有结果,任何人都可以帮忙吗?谢谢。

1429857949:将CONNACK发送到127.0.0.1(0,5)
CONNACK返回码为5表示未授权连接。如果它 使用allow_anonymous = true,然后听起来像你的客户不是 发送用户名/或不发送正确的用户名和密码。
看起来你正在运行一个Paho Python客户端。

我有同样的问题我的解决方案是我没有关闭连接。一旦我添加了client.Disconnect(),它解决了我的问题。
代码:
public IEnumerator ooverhere()
{
MqttClient client;
client = new MqttClient(urlPath, port, false, MqttSslProtocols.None, null, null);
client.ProtocolVersion = MqttProtocolVersion.Version_3_1;
byte code = client.Connect(Guid.NewGuid().ToString(), user, pass);
if (code == 0)
{
Debug.Log("successful connection ...");
//client.MqttMsgPublishReceived += client_recievedMessage;
Debug.Log("your client id is: " + client.ClientId);
client.Subscribe(new string[] { "example" }, new byte[] { 0 });
client.Publish("Helpme", Encoding.UTF8.GetBytes("@" + 0));
yield return client;
client.Disconnect();
}
}
