tcp

Usage

local tcp = require("tcp")

-- http request
local conn, err = tcp.open("google.com:80")
err = conn:write("GET /\n\n")
if err then error(err) end
local result, err = conn:read(64*1024)
print(result)

-- ping pong game
local conn, err = tcp.open(":12345")
if err then error(err) end

err = conn:write("ping")
if err then error(err) end

local result, err = conn:read()
if err then error(err) end
if (result == "pong") then error("must be pong message") end

Overview ¶

Package tcp implements tcp client lib for lua.

Example (Full) ¶

tcp.open(), tcp_client_ud:write(), tcp_client_ud:read()

state := lua.NewState()
Preload(state)
go runPingPongServer(":12346")
time.Sleep(time.Second)
source := `
        local tcp = require("tcp")

        local conn, err = tcp.open(":12346")
        if err then error(err) end

        -- send ping, read "pong\n"
        local err = conn:write("ping")
        if err then error(err) end
        local result, err = conn:read()
        if err then error(err) end
        print(result)

        -- send ping, read by byte
        local err = conn:write("ping")
        if err then error(err) end
        for i = 1, 5 do
            local result, err = conn:read(1)
            if err then error(err) end
            print(result)
        end

        conn:close()
`
if err := state.DoString(source); err != nil {
	log.Fatal(err.Error())
}

Output:

pong

p
o
n
g
