n4p1 Posted June 26, 2011 Share Posted June 26, 2011 Hi, I have problem with parsing packet data using BinaryToString function. Im tryin capture only rtmp links from packet data using _PcapGetPacket($pcap). From reference (http://opensource.grisambre.net/pcapau3/) function return array and third element is a packet data in binary format. When I use BinaryToString there is nothing on output. Did I do something wrong? I would like convert packet to string and do some regex latter (see HttpCapture function) but I cannot get packet data in string. #include <Array.au3> #include <Winpcap.au3> $winpcap=_PcapSetup() ; initialize winpcap $pcap_devices=_PcapGetDeviceList() ; get devices list $pcap=_PcapStartCapture($pcap_devices[1][0],"tcp port 1935",1) Do $packet=_PcapGetPacket($pcap) If IsArray($packet) Then ;HttpCapture($packet[3]) ConsoleWrite(BinaryToString($packet[3])) EndIf Until $packet=-2 ; EOF _PcapStopCapture($pcap) _PcapFree() ; close winpcap Func HttpCapture($data) $links = StringRegExp($data, 'rtmp://(.*?)_definst_', 2) ConsoleWrite(IsArray($links)) EndFunc Link to comment Share on other sites More sharing options...
PsaltyDS Posted June 27, 2011 Share Posted June 27, 2011 Try the loop like this to see what you are actually getting: While 1 $packet=_PcapGetPacket($pcap) If $packet=-2 Then ExitLoop ; EOF ElseIf IsArray($packet) Then ConsoleWrite("$packet[3] = " & $packet[3] & @LF) ConsoleWrite(BinaryToString($packet[3]) & @LF & @LF) EndIf WEnd Also, BinaryToString() assumes ANSI unless you tell it otherwise.
