[WX12] HTTP PUT and HTTP DELETE methods via httpRequest()

Hi,

Back from holidays and I finaly am getting the Google Calendar integration to work (logon, creation of events on other persons calendars, retrieving calendars and events, etc...). Now, I need to also be able to update/delete Google Calendar events based on triggers in my app. This requires HTTP PUT and HTTP DELETE method calls. I have the impression that the WX httpRequest() command only supports HTTP POST and HTTP GET methods. Is that correct? If so, has any of you found a workaround to this big limitation?

Thank you for your feedback!

Cheers,

Hi,

Looking into the http protocol and the Google API's I found a way to override the http method using a simple POST statement (and thus using the httpRequest() command).
It requires an additional header (which is possible as the third parameter of the httpRequest() command and which I already use to provide an additional authentication header).
The syntax is like this: X-HTTP-Method-Override: PUT
However, I can't seem to get it to work using httpRequest() since it always times out if I add this additional header. Any guru's out there that can help me out?

Cheers,

Peter H.

Hi Peter,

In the help, on HTTPRequest, there is a section at the bottom explaining how to PUT informations with the function (I have the French help). Did you take a look at it and gave it a try?

HTTPRequest("url",*,*,"FIELD1=Value"+CR+"FIELD2=Value"+CR+"submit")

Regards.

Hi Alexandre,

Thank you for your feedback. This might be an option, but I am not submitting a form (with fields) but an XML request (other content-type) so this doesn't seem to be an option. However, I'll have a closer look later today.

Cheers,

Peter

Hi Guys,

Have you solved that problem with submitting XML file. I have already same problem. I need to create small script which can create XML file and after that submit to other server API.

Tell me please httpRequest() is going to work or should I use something different?

Thanks

David

It works but it took me a lot of headaches...
Here's a sample call that should get you going:
(Note global member URL_GCAL_CONT_TYPE_ADD = "application/atom+xml" and URL_GCAL_REQUEST_AGENT = "Mozilla/4.0 (compatible; MSIE 6.0; Winrdows NT 5.0)")

...blablabla previous code in Method FUNCTION gCal_AddEvent(lint_CoworkerID is int = 0)
	//Set URL
	lstr_gCalendarURL = StringBuild(::URL_GCAL_REQUEST,:str_gCalAccount)
	lstr_GCalendarAUTHHeader = StringBuild(::URL_GCAL_REQUEST_AUTH_HEADER,:str_gCalLoginAUTH)
	//Build XML Message
	//%1 = Title or subject
	//%2 = Body
	//%3 = Location
	//%4 = Startdate yyyy-mm-dd	%5 = Starttime HH:MMS:CCC
	//%6 = Enddate yyyy-mm-dd	%7 = Endtime HH:MMS:CCC
	//%8 = Reminder days
	lstr_XMLBody = StringBuild(:ML_GCAL_ADD_EVENT, TextToXML(MeetingRequest.Subject), TextToXML(MeetingRequest.Notes), TextToXML(MeetingRequest.Location), ...
	TextToXML(DateToString(MeetingRequest.MeetingDate,"AAAA-MM-JJ")),TextToXML(TimeToString(MeetingRequest.StartTime,"HH:MMS")), ...
	TextToXML(DateToString(MeetingRequest.MeetingDate,"AAAA-MM-JJ")),TextToXML(TimeToString(MeetingRequest.EndTime,"HH:MMS")),"1440")
	//Convert to UTF8 
	lstr_XMLBodyAsUTF8 = StringToUTF8(lstr_XMLBody)
	IF lstr_XMLBodyAsUTF8 <> EOT THEN
		lstr_XMLBody = lstr_XMLBodyAsUTF8
	END
	//Send HTTP Request
	IF HTTPRequest(lstr_gCalendarURL,::URL_GCAL_REQUEST_AGENT,lstr_GCalendarAUTHHeader,lstr_XMLBody,::URL_GCAL_CONT_TYPE_ADD) THEN
		//Get reply
		lstr_gCalHeaderReply = HTTPGetResult(HTTPHeader)
		lstr_gCalDetailReply = HTTPGetResult(HTTPResult)
		//	200 OK No Error. 
		//	201 CREATED Creation of A resource was successful. 
		//	304 NOT MODIFIED The resource hasn't changed since the time specified IN the request's IF-Modified-Since header. 
		//	400 BAD REQUEST Invalid request URI OR header, OR unsupported nonstandard parameter. 
		//	401 UNAUTHORIZED Authorization required. 
		//	403 FORBIDDEN Unsupported standard parameter, OR authentication OR authorization failed. 
		//	404 NOT FOUND Resource (such as A feed OR entry) NOT found. 
		//	409 CONFLICT Specified version number doesn't match resource's latest version number.

...blablabla next code in method

And now... as of version 14, all Google apps are natively integrated into W-Language using Gglxxx commands... This could have saved me lots of time...
