How to ingore the Certificate ERROR in WinHTTP function?

[Nurav]

Thank you all for your kind educational and informative posts. I am kinda new here, even after searching a lot here and MSDN I am not properly able to ignore the "Certificate ERROR" in WinHTTP function.

The URL I am trying to access is "https://208.69.230.55/getHavaIp?hava_name=vgm", if you access from browser it will show certificate error and I have to add exception in Firefox. (IE7 Does not allow me to add exception)

The response of the URL is expected to be...

<ROOT>

−

<RETURNSTATUS>

<STATUS>1</STATUS>

<RESPONSECODE>408</RESPONSECODE>

<RESPONSEDETAIL>HAVA is not active</RESPONSEDETAIL>

</RETURNSTATUS>

</ROOT>

Here is that code I wrote... and thank you all for your kind patience and guidance.

#include<WinHTTP.au3>

;https://208.69.230.55/getHavaIp?hava_name=vgm
$LocalIP = "208.69.230.55"
$hw_open = _WinHttpOpen()
$hw_connect = _WinHttpConnect($hw_open, $LocalIP)
$h_openRequest = _WinHttpOpenRequest($hw_connect, "get", "getHavaIp?")
$data = "hava_name=vgm"

_WinHttpSendRequest($h_openRequest,$WINHTTP_NO_ADDITIONAL_HEADERS, "",StringLen($data), 0)

_WinHttpWriteData($h_openRequest, $data)

_WinHttpReceiveResponse($h_openRequest)

MsgBox(0, 'Recived', _WinHttpReadData($h_openRequest))

_WinHttpCloseHandle($h_openRequest)

_WinHttpCloseHandle($hw_connect)

_WinHttpCloseHandle($hw_open)

Thank you all...

tried for so long, I am having no clue

"https://..." means you have to use $INTERNET_DEFAULT_HTTPS_PORT in _WinHttpConnect().

Also you must specify $WINHTTP_FLAG_SECURE in _WinHttpOpenRequest().

You didn't even connect properly to get "Certificate ERROR" error.

[Nurav]

I have honestly tried all the permutations and combinations like a stupid without even able to understand this whole http technology!

The tip you gave I had tried before, that too didn't help me

I am getting "ERROR_INTERNET_OPERATION_CANCELLED" (ERROR CODE = 12017) for _WinHttpReceiveResponse

means "The operation was canceled, usually because the handle on which the request was operating was closed before the operation completed."

thanks a lot for looking into this.

#include<WinHTTP.au3>

;https://208.69.230.55/getHavaIp?hava_name=vgm
$LocalIP = "208.69.230.55"
$hw_open = _WinHttpOpen()
$hw_connect = _WinHttpConnect($hw_open, $LocalIP,$INTERNET_DEFAULT_HTTPS_PORT)
$h_openRequest = _WinHttpOpenRequest($hw_connect, "get", "getHavaIp?","","","",$WINHTTP_FLAG_SECURE)
$data = "hava_name=vgm"

_WinHttpSendRequest($h_openRequest,$WINHTTP_NO_ADDITIONAL_HEADERS, "",StringLen($data), 0)

_WinHttpWriteData($h_openRequest, $data)

_WinHttpReceiveResponse($h_openRequest)

MsgBox(0, 'Recived', _WinHttpReadData($h_openRequest))

_WinHttpCloseHandle($h_openRequest)

_WinHttpCloseHandle($hw_connect)

_WinHttpCloseHandle($hw_open)

That's certainly more like it.

I'm not sure you should be doing _WinHttpWriteData(). Your code lack _WinHttpQueryDataAvailable() function.

Find some working example of https somewhere.

[Nurav]

working example of https is available, but none of them explain about ignoring the certificate part...

[trancexx]

So you have working example but you couldn't even connect properly.

Nurav believe me when I say that you didn't come close to the certificate part. Do you understand what I'm saying?

[Nurav]

Hi Trancexx,

I have made some changes with the code... The "GetLastError" for SetOptions returns ERROR 87 (ERROR_INVALID_PARAMETER)(0x57)

MSDN Says "GetLastError returns the error ERROR_INVALID_PARAMETER if an option flag is specified that cannot be set."

What am I doing wrong here please! ?

You must set the options before sending the request. Maybe you have to set the options for $hw_connect or $hw_open instead of $h_openRequest, too.

No that didnt help. The QueryOptions then returned 0

[Nurav]

Someone please.....

Please help !

help please!!

[Nurav]

When the gods of Autoit dragged me here and there with a carrot in front I got tired and it did not help me too much. It was quite challenging me for to find a solution. (My never give up attitude) But sometimes it really does not matter how you do it but what matters is did you do it or not. (It is not the way but the destination which really matters. ) I still dont know how to solve this using winhttp.au3 or directly calling the winhttp dll. One of my kind friend resolved this for me after calling winhttp as a com object. (he also gave up the winhttp.au3 after spending 4 days on it.) winhttp - Ignorance is bliss for me!

Too much of story, but I thank all of you who helped, who tried to help, who acted like helping and helpless spectators.

Thank you ProgAndy...

I am sure the change you made will be helpful for others who are facing similar problems. And of course it works beautifully. Thanks again for "REALLY" looking into the problem and the attitude to "HELP" others.

Thanks ProgAndy, your method solved my issue also > http://www.autoitscript.com/forum/index.php?showtopic=116139

_WinHTTPSetOption should be fixed in the new WinHTTP-release (1.6.1.7).
