The way the internet pushes messages is very common, especially mobile Internet, mobile phone can receive a lot of push message every day, after research found that the principle of these push service is to maintain a long connection (or can not achieve real-time effect), but the normal socket connection to the server consumption is too large, So there's a lightweight, low-consumption protocol like MQTT to maintain long connections, so how to maintain

Description: MQTT is an instant Messaging protocol developed by IBM that is likely to be an important part of the Internet of things. The protocol supports all platforms, almost all connected items and external connections, and is used as a communication protocol for sensors and actuators (such as the Internet of homes via Twitter). Apache Apollo is a proxy server, which is developed on the basis of ACTIVEMQ, can support stomp, AMQP,

mosquito is mainly in the function Mosquitto_main_loop, the function mainly accomplishes the following functions:1) Update the information of the system topic;2) Put all the listening sockets into the poll structure Pollfds;3) Scan all the context to complete the following tasks:If the context has a message sent, the message is sent in accordance with the MQTT protocol;Check if the context is timed out;The socket of the context is placed in the poll

MQTT serves as the push message pushing protocol for Android clients. The Android client needs to connect to the MQTT Proxy server via SSL/TLS for encrypted transmission of messages. Implementing this process requires two support, one for the MQTT protocol client and the other for the MQTT proxy server. There are many

When used with tokens on mqttasyncclient, the listener is called back on the Mqtt client's thread. If the operation succeeds or fails, the listener is notified. The Listener quick return control is important, otherwise the operation of the MQTT client will stop. The Imqttasyncclient implements Im
