Improved _INetGetSource


Recommended Posts

i would like this tested before i submit it to some dev.

[edit]

made the buffer from 3 to 256

[/edit]

[edit2]

removed :whistle:

[/edit2]

[edit3]

stripping leftover @CR & @LF at the end

[/edit3]

[edit4]

instead of looping i just trim the last 2 chars to get rid of the leftover enter

reduced filesize a bit

removed edit 2 since it does support ftp://

[/edit4]

[edit5]

added support for Headers & changed user-agent to "AutoIt v3"

[/edit5]

Func _INetGetSource($s_URL, $s_Header = '')
    Local $h_DLL = DllOpen("wininet.dll"), $ai_IO, $ai_IOU, $ai_ICH, $ai_IRF[5] = [0, 0, '', 0, 1], $s_Buf = ''
    $ai_IO = DllCall($h_DLL, 'int', 'InternetOpen', 'str', "AutoIt v3", 'int', 0, 'str', '', 'str', '', 'int', 0)
    If @error Or $ai_IO[0] = 0 Then
        DllClose($h_DLL)
        SetError(1)
        Return 0
    EndIf
    $ai_IOU = DllCall($h_DLL, 'int', 'InternetOpenUrl', 'int', $ai_IO[0], 'str', $s_URL, 'str', $s_Header, 'int', StringLen($s_Header), 'int', 0x80000000, 'int', 0)
    If @error Or $ai_IOU[0] = 0 Then
        DllCall($h_DLL, 'int', 'InternetCloseHandle', 'int', $ai_IO[0])
        DllClose($h_DLL)
        SetError(1)
        Return 0
    EndIf
    Local $v_Struct = DllStructCreate ('udword')
    While $ai_IRF[4] <> 0
        $s_Buf &= StringMid($ai_IRF[2], 1, $ai_IRF[4])
        $ai_IRF = DllCall($h_DLL, 'int', 'InternetReadFile', 'int', $ai_IOU[0], 'str', "", 'int', 256, 'ptr', DllStructGetPtr ($v_Struct, 1))
        $ai_IRF[4] = DllStructGetData ($v_Struct, 1)
    WEnd
    DllStructDelete ($v_Struct)
    DllCall($h_DLL, 'int', 'InternetCloseHandle', 'int', $ai_IOU[0])
    DllCall($h_DLL, 'int', 'InternetCloseHandle', 'int', $ai_IO[0])
    DllClose($h_DLL)
    Return StringTrimRight($s_Buf, 1)
EndFunc;==>_INetGetSource

ConsoleWrite(_INetGetSource('http://www.autoitscript.com') & @LF)

to make cameronsdad happy:

(related to InternetReadFile)

LPVOID had nothing to do with it, just using 'str' was good.

the problem was with "LPDWORD lpdwNumberOfBytesRead" i first just used a 0 and now i use Dllstruct (im sure there is a cleaner way :dance:)

w0uter,

I just curious why you say this is better/more control than COM?

Using COM you can get the same result in 4 lines of code:

Func _INetGetSource($s_URL)
    $WinHttpReq = ObjCreate("WinHttp.WinHttpRequest.5.1")
    $WinHttpReq.Open("GET", $s_URL, false)
    $WinHttpReq.Send()
    Return $WinHttpReq.ResponseText
EndFunc

SciTe Debug mode - it's magic: #AutoIt3Wrapper_run_debug_mode=Y Doesn't work needs to be ripped out of the troubleshooting lexicon. It means that what you tried did not produce the results you expected. It begs the questions 1) what did you try?, 2) what did you expect? and 3) what happened instead?

wow, i almost never look in this forum (mostly just support because thinking on scripts helps pass time at work) and i can't tell you how surprised i was to see my name. Thanks for remembering my request, and yes, it did in fact make me happy.

***edit*** realized i'd quoted all of your code etc and didn't think that was necessary for the small amount i was actually replying to, so i removed it...

COM + non existing URL = total crash.

wOuter, I like your code.

For learning purposes, I'd like to know if there is a way to use the WinHttpRequest.onerror event to trap a failure and use Dale's shorter code?

see edit 5.

i would also like this to replace the current UDF in the beta.

Could you do me a favor and PM or mail me any updates to UDF's (func or docs) because there is always a good chance I am missing posts like this .. tnx ;)

Got this one done ...... so no need to sent that.

WoUter I also like your code I use this in one.

$s_URL = InputBox("WebPage", "Type WebPage To Get Source From")

_INetGetSource($s_URL)

Func _INetGetSource($s_URL)
    $WinHttpReq = ObjCreate("WinHttp.WinHttpRequest.5.1")
    $WinHttpReq.Open("GET", $s_URL, false)
    $WinHttpReq.Send()
    ClipPut($WinHttpReq.ResponseText)
    Run("Notepad.exe")
    WinWaitActive("Untitled - Notepad")
    Send("{CTRLDOWN}v{CTRLUP}")
EndFunc
