示例

-- Publishes a service of type '_corona_test._tcp' and then starts discovery for the service

-- Require the plugin
local zeroconf = require( "plugin.zeroconf" )

-- Listener to be called for ZeroConf events
local function zeroconfListener( event )

    -- Service has been found
    if ( event.phase == "found" and not event.isError ) then

        print( "SERVICE FOUND" )
        print( "-------------" )

        if event.serviceName then
            print( "Service name: " .. event.serviceName )
        end

        if event.port then
            print( "Port: " .. tostring(event.port) )
        end

        if ( event.addresses and #event.addresses > 0 ) then
            print( "Service provider addresses:" )
            for i = 1,#event.addresses do
                print( "  " .. event.addresses[i] )
            end
        end

    -- Service has been lost!
    elseif event.phase == "lost" then

        print( "SERVICE LOST!" )
        print( "-------------" )

        if event.serviceName then
            print( "Service name: " .. event.serviceName )
        end
    end
end

-- Initialize listener
zeroconf.init( zeroconfListener )

-- Generate a service name
local serviceName = system.getInfo("name") .. " (" .. system.getInfo("platformName") .. ")"

-- Publish a service (make it discoverable over the network)
local service = zeroconf.publish( { port=2929, name=serviceName, type="_corona_test._tcp" } )

-- Start looking for published services
local browser = zeroconf.browse( { type="_corona_test._tcp" } )
