Using TCP for HTTP Requests

[Slythfox]

I want to avoid using IE to make a http server request. I have a working apache server, and have set up a php script called write.php that will write to a file if it is accessed.

I know this isn't working because the file hasn't been written to (the write.php file has been tested).

#include <GUIConstants.au3>
TCPStartUp()

Dim $ConnectedSocket = -1
$ConnectedSocket = TCPConnect("192.168.0.6",80)

Dim $szData

If @error Then
    MsgBox(4112,"Error","TCPConnect failed with WSA error: " & @error)
Else
    TCPSend($ConnectedSocket,"GET /write.php HTTP/1.1\r\nHost: 192.168.0.6\r\n\r\n")
EndIf

What am I doing wrong?

Well... I'm not sure.. but I think that all this does is send a string:

TCPSend($ConnectedSocket,"GET /write.php HTTP/1.1\r\nHost: 192.168.0.6\r\n\r\n")

That's how stuff works. For example, in IRC you use stuff like PRIVMSG NickServ :IDENTIFY

I did some packet sniffing, but I can't seem to get this HTTP TCP stuff to work.

Maybe do a search for so autoit made webservers? That will probably point you in the right direction

I've been looking at those and haven't found anything that leads me to anything.

Is it really that hard to request (but not download) a page on a web server, without the use of the IE libraries?

Instead of:

TCPSend($ConnectedSocket,"GET /write.php HTTP/1.1\r\nHost: 192.168.0.6\r\n\r\n")

You should try:

TCPSend($ConnectedSocket,"GET /write.php HTTP/1.1" & @CRLF & "Host: 192.168.0.6" & @CRLF & @CRLF)

Probably you grabbed your code from some PHP code but in Autoit you'll have to use @crlf instead of \r\n

Thanks, that worked! I didn't realize I needed to do that.

Some servers will require you to have additional lines on your requests to specify the host you want and the connection type.

I have some semi-private UDF's of my own that I use for HTTP, it's not complicated once you figure it out.

This page has alot of info on HTTP:
