Touch Genie Remote Log Module

First, the function

The Lua log method automatically discovers log servers under the same network segment

The Lua log method can proactively send logs to the server

LUA Client process Restart service side no impact

Second, the realization

The server is written using Python:

Start a thread, listen to a specific port with UDP, accept the client's scan, and the port of the feedback log

Starts a thread, listens on a specific port, accepts a TCP connection, dispatches a new log thread to process log

The client uses LUA to write:

Before printing log, use the UDP socket to scan the server's log port and create a TCP socket send log

Third, the source code:

Server:

　　

Import Socketimport timeimport Reimport threadudp_listen_port = 31500tcp_listen_port = 31501stop_udp_server = Falsedef ge  Tlocalip (): MyName = Socket.getfqdn (Socket.gethostname ()) myaddr = Socket.gethostbyname (myname) return myaddr;def GetTime (): Return Time.strftime ('%y-%m-%d%h:%m:%s ', Time.localtime (Time.time ())) def Log (content): Print ("[%s]:%s" % (GetTime (), content)) def startudpserver (): Address = (Getlocalip (), udp_listen_port) s = Socket.socket (socket.af_i NET, Socket.

Continue Log (' received%s from%s '% (data, addr)) Client_ip_port = ' {0}:{1} '. Format (addr[0],add R[1]) Pat = Re.compile ("^ (\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}):(\d+) $") for Ip,port in Pat.findall (client_ip_        Port):    Log (' Got iphone addr:port =%s%s '% (IP, port)) Local_addr_port = (Getlocalip (), Tcp_listen_port)            Log (' Rsp server Addr:port =%s%s '% local_addr_port) Rsp_data = ' {0} '. Format (local_addr_port[1])    S.sendto (rsp_data,addr) break; S.close () def starttcplogserver (sock,client): while (True): Try:data = SOCK.RECV (4096) if D Ata:pat = Re.compile (' \[(. *?)        \] ') for log in Pat.findall (data): Log (log) Else:break;    Except Socket.error:sock.close () Break Log (' Client (%s,%s) close '% client); Sock.close () def starttcplistenserver (): #create tcp Socket sock = Socket.socket (socket.af_inet, socket.

Client:

Four, the way to load Luasocket in client Lua is as follows:

LocalSZ =require("sz")LocalHTTP =require("szocket.http")LocalRes, code = http.request ("http://www.baidu.com");ifCode = = $  ThenLog ("Start") Log (RES) dialog (res),0); Log ("End")End
