Timeout Issues with WinHTTPRequest5.1 (COM Object) Topic is solved

[Tigerlily]

Hello,

I've tested this using my web browser, however when using WinHttp to retreive this information, it appears to "time out" and give up when the response takes "too long".

In my web browser (Chrome), it does take quite some time to retreive the result of this API request, possibly a whole minute. From my limited experience with using WinHttp in AHK, I've noticed that even when the URL given is a valid https:// URL, when it takes a significant time to load the web page in my browser (15-25+ seconds), WinHttp seems to give up before waiting long enough to get the results.

My question is: is there any way around this?? Can I tell this WinHttp to wait longer for the response (because I know there is a response coming)?

Here is my current code, any URL that takes a very long time to load should suffice for the URL variable here.

Code: Select all

try 
{ 
	URLaddress := "https://iprospectus.getstat.com/api/v2/26480a9sidfj3098sjaskdfg45hg5ea12e8589edc898/sites/all?format=json"

	whr := ComObjCreate("WinHttp.WinHttpRequest.5.1") 


	;=======;		RETRIEVE WEB DOCUMENT		;=======;

		whr.Open("GET", URLaddress, true)
		whr.Send()
		whr.WaitForResponse()


	fileContents := whr.ResponseText	;	Save web document to variable
}
MsgBox % fileContents

I've looked in the >>MSDN docs for WinHttpRequest object<< to try and figure it out myself.

I tried using whr.WaitForResponse(-1), but that still did not make timeout infinite..

I also tried using the event whr.OnResponseFinished, but my programming skill is not high enough to know how to use Events yet (or so I think).

Any help is much appreciated. Also, if there is a better way to do this, then that would be awesome.... I tried using URLDownloadToFile and the file will not create (so I'm assuming the same issue is being encountered). Am I missing something??

When I take out the try command, I get this error:

---------------------------

235: whr := ComObjCreate("WinHttp.WinHttpRequest.5.1")
240: whr.Open("GET", URLaddress, true)
242: whr.Send()
243: whr.WaitForResponse()
246: {
---> 247: MsgBox,fileContents := whr.ResponseText
248: }
319: Return
333: {


Continue running the script?

Yes No

After I retreive the JSON data associated with this API Call, I will need to parse it quickly into Excel.. so will post another Q about that once I figure this one out.

Thanks so much for your help!!!!!!!!!!!

Woohoo with a little more digging I found out the answer to my problem. I needed to set the timeout parameters with
whr.SetTimeouts()

IWinHttpRequest::SetTimeouts method

Here is my working code:

Code: Select all

try 
{ 
	URLaddress := "https://iprospectus.getstat.com/api/v2/26480a9sidfj3098sjaskdfg45hg5ea12e8589edc898/sites/all?format=json"

	whr := ComObjCreate("WinHttp.WinHttpRequest.5.1") 


	;=======;		RETRIEVE WEB DOCUMENT		;=======;
		whr.SetTimeouts(0,30000,30000,120000)
		whr.Open("GET", URLaddress, true)
		whr.Send()
		whr.WaitForResponse()


	fileContents := whr.ResponseText	;	Save web document to variable
}
MsgBox % fileContents

The first 3 parameters for the SetTimeouts method are the default (millisecond) values for ResolveTimeout, ConnectTimeout, and SendTimeout.

The last parameter is the one I needed to modify, which is ReceiveTimeout.

Yay!
