Lua Requires Chilkat v11.0.0+

Accept Connection on Socket

See more Socket/SSL/TLS Examples

Demonstrates how to create a TCP/IP socket, listen on a port, accept an incoming connection, and send a "Hello World" message to the client. Lua

local chilkat = require("chilkat")

-- This example requires the Chilkat API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

local listenSocket = chilkat.Socket.new()

-- Bind to a port and listen for incoming connections:
-- This example will listen at port 5555 and allows for a backlog
-- of 25 pending connection requests.
local success = listenSocket:bind_and_listen(5555, 25)
if not success then
    print(listenSocket.last_error_text)
    return
end

-- Get the next incoming connection
-- Wait a maximum of 20 seconds (20000 millisec)
local connectedSocket = chilkat.Socket.new()
success = listenSocket:accept_next(20000, connectedSocket)
if not success then
    print(listenSocket.last_error_text)
    return
end

-- Set maximum timeouts for reading an writing (in millisec)
connectedSocket.max_read_idle_ms = 10000
connectedSocket.max_send_idle_ms = 10000

-- Send a "Hello World!" message to the client:
success = connectedSocket:send_string("Hello World!")
if not success then
    print(connectedSocket.last_error_text)
    return
end

-- Close the connection with the client.
-- Wait a max of 20 seconds (20000 millsec)
success = connectedSocket:close(20000)

print("success!")
