开源软件名称（OpenSource Name）：flukso/lua-mosquitto开源软件地址(OpenSource Url)：https://github.com/flukso/lua-mosquitto开源编程语言(OpenSource Language)：C 71.9%开源软件介绍(OpenSource Introduction)：lua-mosquittoLua bindings to the libmosquitto client library. The parameters to all functions are as per libmosquitto's api only with sensible defaults for optional values, and return values directly rather than via pointers. Generated API documentation for the lua functions is also available (Direct link if you are within github) CompileYou need Lua and mosquitto development packages (headers and libs) to build lua-mosquitto. Compile with You can override the pkg-config package name to set a specific Lua version. For example: Example usageHere is a very simple example that subscribes to the broker $SYS topic tree and prints out the resulting messages: mqtt = require("mosquitto")
client = mqtt.new()
client.ON_CONNECT = function()
print("connected")
client:subscribe("$SYS/#")
local mid = client:subscribe("complicated/topic", 2)
end
client.ON_MESSAGE = function(mid, topic, payload)
print(topic, payload)
end
broker = arg[1] -- defaults to "localhost" if arg not set
client:connect(broker)
client:loop_forever()Here is another simple example that will just publish a single message, "hello", to the topic "world" and then disconnect. mqtt = require("mosquitto")
client = mqtt.new()
client.ON_CONNECT = function()
client:publish("world", "hello")
local qos = 1
local retain = true
local mid = client:publish("my/topic/", "my payload", qos, retain)
end
client.ON_PUBLISH = function()
client:disconnect()
end
broker = arg[1] -- defaults to "localhost" if arg not set
client:connect(broker)
client:loop_forever()
