Problem with Winhttp readystate value

Recommended Posts

delstone123

Hi

I have the following code which does an async http post:

$oHTTP[$i] = ObjCreate("WinHttp.WinHttpRequest.5.1")

    $oHTTP.Open("POST", $sURL, TRUE)
    If (@error) Then Return SetError(1, 0, 0)

    $oHTTP.SetRequestHeader ("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:27.0) Gecko/20100101 Firefox/27.0")
    $oHTTP.Send($sData)
    If (@error) Then Return SetError(2, 0, 0)

    ;...some other processing...

    HttpWait($HTTP)

When I call the function httpwait() to wait for the response and see what it is I don't get any value for readystate.

status however comes back quickly with a 200 but the request isn't fully complete as part of its header content is missing.

If I change the original post to synchronous (by changing the open parameter to FALSE: $oHTTP.Open("POST", $sURL, FALSE)) then it all works fine and returns the full header content.

Something is not set for asynchronous processing but I'm not sure what.

Func HttpWait($oHTTP)
    Local $i = 0

    Do
        Sleep(25)
        $i+= 1
    Until $oHttp.read == 4 And $oHTTP.status == 200 Or $i > 100

    ConsoleWrite("readystate "&$oHTTP.ReadyState & " status " & $oHTTP.Status & @CRLF)
EndFunc

Any thoughts what I'm doing wrong?

It appears you are mixing object property names between:

WinHttpRequest.5.1 --and-- InternetExplorer.Application.

There is no such property as "Read" or "ReadyState"

in the WinHttpRequest.5.1 object.

Those are in the InternetExplorer.Application object.

Here's the list of Methods and Properties for the WinHttpRequest.5.1 object.

http://msdn.microsoft.com/en-us/library/windows/desktop/aa384106(v=vs.85).aspx

Here's something to play with...

Func _WinHttpRequest($sURL, $sData = '')
    Local $oHTTP = ObjCreate('WinHttp.WinHttpRequest.5.1')

    $oHTTP.Open('HEAD', $sURL, True)
    If @error Then Return SetError(1, 0, 0)

    $oHTTP.SetRequestHeader('User-Agent', 'http_requester/0.1')

    $oHTTP.Send($sData)
    If @error Then Return SetError(2, 0, 0)

    ;$oHTTP.WaitForResponse(5); <-- seconds

    ; -- Or --

    For $i = 1 To 100
        If $oHTTP.status == 200 Then ExitLoop
        Sleep(25)
    Next

    MsgBox(0, 'Loops: ' & $i & '  -  Status: ' & $oHTTP.Status, $oHTTP.GetAllResponseHeaders)
EndFunc
