download file from https (WinHttp.au3)

[Kamir]

Hi, 
How can I did it?

I download files (XML) from internal website. When I type in webbrowser "https://wso2am.ccc.dd:8877/zzz/firm/1.0/get/TTT/2023-09-18?apikey=zzzzzzzzzzzzzz" then the file appears in the browser.
I can also download this file using cUrl:
curl.exe -k -o tmp\TTT20230918.xml https://wso2am.ccc.dd:8877/zzz/firm/1.0/get/TTT/2023-09-18?apikey=zzzzzzzzzzzzzz

I am trying to download this file using WinHttp, but I don't know how.

I am trying this:

#include "WinHttp.au3"

Local $url = "https://wso2am.ccc.dd/zzz/firm/1.0/get/TTT/2023-09-18"
Local $api = "?apikey=zzzzzzzzzzzzzz"


; Initialize and get session handle
Global $hOpen = _WinHttpOpen()
; Get connection handle
Global $hConnect = _WinHttpConnect($hOpen, $url, "8243")
If @error Then
    ConsoleWrite("errA: " & @error & @cr)
Else
    ConsoleWrite("hconnect: " & $hConnect & @cr)
EndIf


Local $sReturned = _WinHttpSimpleSSLRequest($hConnect, "GET", $api)
If @error Then
    ConsoleWrite("errB: " & @error & @cr)
EndIf

$hConnect is OK, but I receive error 02 (could not send request) in _WinHttpSimpleSSLRequest
Why? What am I doing wrong?

Have you seen this thread?

 

[Kamir]

yes, I wanted to write my script based on this thread.

[Danp2]

I think you've got modify your URL and key. Try this to see if you get any further --

Local $url = "wso2am.ccc.dd"
Local $api = "/zzz/firm/1.0/get/TTT/2023-09-18?apikey=zzzzzzzzzzzzzz"

 

[Kamir]

the same, connect OK, request - error 2, maybe I should add something to check more precisely what the problem is?

[Danp2]

How do you explain the difference in server port (8877 vs 8243)?

[Kamir]

In my original script everything is ok with the port, here I changed the data in order not to make public the real data. With the port came out a little mishap

[Danp2]

The problem is likely due to a security issue (ie: self signed certificate). You could try adding the following prior to the _WinHttpSimpleSSLRequest --

_WinHttpSetOption($hRequest, $WINHTTP_OPTION_SECURITY_FLAGS, BitOR($SECURITY_FLAG_IGNORE_UNKNOWN_CA, $SECURITY_FLAG_IGNORE_CERT_DATE_INVALID, $SECURITY_FLAG_IGNORE_CERT_CN_INVALID, $SECURITY_FLAG_IGNORE_CERT_WRONG_USAGE))

The above was copied from here.

I didn't find this before, but unfortunately it didn't help. Same error 2.

IDK. 🤷‍♂️ Hopefully someone else will jump in with some additional ideas for you.

[Kamir]

but now, I've got error 4 (DllCall failed) after _WinHttpSetOption

[Kamir]

Thank you for your involvement, if there are further attempts to help - I will check, but I will probably end up using curl.

You didn't post your revised code, so we can only make a guess at the problem. Did you fix up the line I posted to fit with your existing code ($hRequest vs $hOpen)?

What is your OS? Have you verified that _WinHttpCheckPlatform() returns 1?

[Kamir]

Windows 10 64 bit, and 2 yes - I verified that _WinHttpCheckPlatform() returns 1 and of coursce I fix $hRequest to $hOpen. Unfortunately, it is not possible to access this page from outside, so I realize that it is even more difficult to solve the problem. But thank you for your time!

Would this be an idea?

Googling: WinHttp stunnel

Another possible idea, try with this UDF:
