Possible bug with TCP functions?

Recommended Posts

Zonarius

Maybe I'm doing something wrong, but please try this:

TCPStartup()
myGet("www.google.at", "/intl/de_at/images/logo.gif")
TCPShutdown()

Func myGet($host, $file, $headers = "")
    Local $req
    Local $ip
    Local $ms
    Local $fp
    Local $recv

    $req = "GET " & $file & " HTTP/1.1" & @CRLF
    $req &= "Host: " & $host & @CRLF
    $req &= $headers
    $req &= @CRLF

    
    $ip = TCPNameToIP($host)
    $ms = TCPConnect($ip, 80)
    TCPSend($ms, $req)
    Sleep(1000)
    $recv = TCPRecv($ms, 1000000)
    TCPCloseSocket($ms)
    
    $fp = FileOpen("logo.gif", 2)
    FileWrite($fp, BinaryToString($recv))
    FileClose($fp)
EndFunc   ;==>myGet

What I receive is this:

HTTP/1.1 200 OK
Content-Type: image/gif
Last-Modified: Fri, 07 Dec 2007 01:42:40 GMT
Expires: Sun, 17 Jan 2038 19:14:07 GMT

A bit too little for a picture.

So I watched traffic with a tool and I do receive the complete image, but i don't get it with AutoIt.

Is this a bug or am I doing something wrong?

I would expect that you should open the file in binary mode and save the recieved data without converting it to a string

$recv = TCPRecv($ms, 1000000,1);force binary
    TCPCloseSocket($ms)
   
    $fp = FileOpen("logo.gif", 16+2);force binary
    FileWrite($fp, $recv);
    FileClose($fp)

but that still doesn't work.

This works

inetget("http://www.google.at/intl/de_at/images/logo.gif","logo2.gif")

but that might not be any help.


Serial port communications UDF Includes functions for binary transmission and reception.printing UDF Useful for graphs, forms, labels, reports etc.Add User Call Tips to SciTE for functions in UDFs not included with AutoIt and for your own scripts.Functions with parameters in OnEvent mode and for Hot Keys One function replaces GuiSetOnEvent, GuiCtrlSetOnEvent and HotKeySet.UDF IsConnected2 for notification of status of connected state of many urls or IPs, without slowing the script.

It works with inetget, but it has to work with the TCP functions, doesn't it?
