Use Function In TCP

5 posts in this topic

Hi,

How can i use a external function in TCPSend / TCPRecv ,

It's meant : 

TCPSend ( $main, function1 )

func function1 ()
msgbox (0,0,0)
endfunc

Q : Why i need to use that ? 

A : I need when a connection was true ( connected ) , server could send some functions and client receive that,

Me => :console:<= You

Thanks

Bump

======================

Something like that : 

Server : 

TCPSend ( $main, function1 )

func function1 ()
msgbox (0,0,0)
endfunc

Client :

TCPRecv ; recive the msgbox (function1) sended from server

:sweating:

You can't do it that simply.  You cannot simply feed source code across a tcpsend and have the receiving side execute that function.  Yes, can you send data to a machine and have it act on that data, but you have to define those actions and validate the data.

Hhmmm, thanks, can you make for me an simply example ? :console:

You must get the server's command on the client side and execute it.

Example (actually I'm using my TCPClient UDF, get the download link on my signature but do not confuse with TCPServer UDF):

#include 'tcpclient.au3'
_TCPClient_OnReceive("onreceive")
_TCPClient_Connect("ip", "port") ; ???????
Func onreceive($iSocket, $sIP, $sData, $sPar)
  Execute($sData) ; read below before using this code
EndFunc

So the server will send the code to execute, like this:

TCPSend($socket, "MsgBox(0, '', 'hey')")

And it will run on the client side.

However, it's too dangerous to open a port to receive codes to your computer, as a hacker may discover it and execute AutoIt functions that may harm your system completely. Instead of Execute()-ing, like I did above on the example, you could have a predefined list of allowed commands, and run them only. Also, find out some way to make sure the server is authorized to run commands on your machine. Passwords would be nice, but I don't know exactly what you are doing...

      Hi,
      I wonder if
      AutoIt3Wrapper_run_debug_mode = Y can include run information about functions which are called within the main code. So far I noticed in the console that the function itself is called but no specific run information from  inside the function is provided. Is there a chance to show the entire debug log including functions in the console?
      I furthermore noticed a stop of information when a loop is entered. What could be the reason for that?
       
      Thanks for help.

      AutoIt-SocketIo
      Yep yep, this is pretty much an attempt to port the existing project's concept https://socket.io/ to AutoIt's Codebase. So i will not go in to so much detail.
      This is how the communication is done http://i.imgur.com/0mMfsBD.png Each client is isolated to the server http://i.imgur.com/rVO2LFb.png Features
      Easy API VarType Translation (Example: If the server sends an int, the client will receive an int and vice versa) Fully featured examples Data encryption (Using Autoit's UDF Crypt.au3) Limitations / Drawbacks
      Every Broadcast/Emit is limited to a maximum of 16 parameters Every Callback Function has to have the same number of parameters as the Broadcasted/Emited event It is not possible to Broadcast/Emit objects Only 1D-arrays are allowed to be Broadcasted/Emitted (2D arrays will probably never be supported) Changelog
      Version 1.4.0 (This update DOES NOT break scripts)
      Added a new server method: _Io_getSockets which will return an array of all sockets. See more in the doc Added a banning-system, see more at: _Io_getBanlist, _Io_Ban, _Io_Sanction, _Io_IsBanned Added a new default event for clients banned. See more at default events Added two new client and server methods _Io_setEventPreScript And _Io_setEventPostScript. The intent for these is to not DRY when doing debug \ tasks that requires to be ran before or after events. Added a new client and server method _Io_ClearEvents. Added a third optional parameter to _Io_On called $socket, you may only pass the socket returned from _Io_Listen or _Io_Connect. The intent for this change is to allow for server + client in the same envoirment. Added a second parameter to _Io_Loop called $WhoAmI which should used with the new enums $_IO_SERVER and $_IO_CLIENT. The intent for this change is to allow for server + client in the same envoirment. Added a new client method _Io_TransferSocket. Added a new server method _Io_getActiveSocketCount. Optimations, avoiding Redims and unnecessary nested arrays as good as possible etc. Version 1.3.0 (This update DOES NOT break scripts)
      Got rid of unnecessary Redims with sockets and subscriptions in the main loop (This increased write performence greatly) Changed $iMaxDeadSocketsBeforeTidy from 100 to 1000 Changed _Io_setRecvPackageSize($nPackageSize = 2048) to _Io_setRecvPackageSize($nPackageSize = 4096) because 2017. Added Tests for both subscriptions and the automatic TidyUp Added a new server method: _Io_getMaxConnections Added a new server method: _Io_getMaxDeadSocketsCount Added a fifth parameter to the _Io_Listen method called $iMaxConnections which defaults to 100000. If the iMaxConnection + 1 user connects, they will be instantly disconnected. Added a parameter to _Io_Disconnect called $socket which defaults to null. If the iMaxConnections + 1 client connects, they will be instantly disconnected. Version 1.2.0 (This update DOES NOT break scripts)
      Added an option to set the packet-size of TCP-transports, see _Io_setRecvPackageSize Got rid of unnecessary StringLen's in _Io_loop Changed __Io_TidyUp to _Io_TidyUp and added it to the public Api reference list. Changed $iMaxDeadSocketsBeforeTidy default value from 1000 to 100 and added an option to disable it, read more at _Io_Listen Changed $bAutoReconnect from False to True. Fixed gitignore epicZ fail Improvemend Documentation Version 1.1.0 (This update DOES NOT break scripts)
      Fixed bug when Emitting / Broadcasting without any parameters causing a $fCallback crash Optimized Package-handling once again. Added 1D-Array support (Endless nestning). Added Subscriptions (See _Io_Subscribe _Io_Unsubscribe and _Io_BroadcastToRoom). Added new example for subscriptions (Be sure to use different room names when joining with clients) Added Unit testing (See Tests\Runner.au3 and Tests\Tests.au3, to run tests you need a udf found here: https://github.com/tarreislam/Autoit-Unit-Tester) Version 1.0.0
      (This update DOES NOT break scripts) Added data encryption (Using Autoit's UDF Crypt.au3) See more at _Io_EnableEncryption Added new method _Io_Disconnect which can be used with both servers and clients Improved package-handling to increase performance Increased the limit of Broadcasted/Emit parameters from 10 to 16 Api methods

      Hello all.
      In case this is interesting few of you, I share my AMCP 2.1 protocol UDF in AutoIT. This protocol is used by CasparCG server, which is a Windows and Linux software used to play out professional graphics, audio and video to multiple outputs as a layerbased real-time compositor. It has been in 24/7 broadcast production since 2006. It's free and opensource.
      The UDF I share allows communication between an AutoIt based client and the CasparCG, based on following documentation : http://casparcg.com/wiki/CasparCG_2.1_AMCP_Protocol
      If you want more details on CasparCG :  official WebSite or have a look to this video
      I'm currently building a full Client based on AutoIt, with many features like drag-and-drop layers, but sadly I can't share it right now, might come later. Don't hesitate to ask questions if you have any or need a basic example.
      The only requirement for this UDF is the other Event-driven TCP UDF by Kip
