Web Server - Ask For Help / How to get the complete HTTP data stream?
« on: October 14, 2015, 02:46:48 AM »
(Using NetTalk 5,45 (sorry 
) is used in an old Clarion 6.3 app.)
A JSON string is passed to my NetWebpage procedure.
JSON request:
{
"Login": "xxxx",
"Password": "yyyy",
"FiliaalID": "3"
}
How do I get the JSON string?
The following does the job for an XML string:
pweb:DataJson = p_web.GetValue('xml')
But how to I get the JSON string?
And if not possible in 5.45, how do I get the complete HTTP stream (headers and data)?

Web Server - Ask For Help / How to test for the www.xxxxx.com?wsdl parameter?
« on: September 11, 2015, 02:34:43 AM »
(NetTalk 6 - handcoded NetWebPage procedure)
I have to return a SOAP WSDL definition to everyone who requests www.xxxxx.com?wsdl.
How do I test in my netWebpage for the presence of the ?wsdl parameter?
I tried ...
If p_web.IfExistsValue('wsdl')
message('yes')
Else
message('no')
End
But it doesn't work for www.xxxxx.com?wsdl
It does work for www.xxxxx.com?wsdl=1
but this is not an option.
(and going to NetTalk 8 is also not an option, because my program is still in C6)
(and going to C9 is not an option, because I don't have the time for the moment :-) )

Web Server - Ask For Help / How long is a variable (not a session variable) valid?
« on: February 09, 2014, 08:38:02 AM »
In a WebSource procedure, I assign some value to a v:PDL variable.
(not a SESSION variable, just an ordinary, short living variable).
After this, I include some HTML with the net:f include file directive and terminate my WebSource procedure.
p_web.SetValue('PDL', 'test')
_('<!-- Net:f:/htm/navbar.htm -->')
_('<!-- Net:f:/htm/logon.htm -->')
RETURN ! terminates my WebSource procedure
PS: the underscore is a home written procedure and just a shortcut for a Do SendPacket.
It keeps the html that I send to the browser clean and readable in my source code.
In my logon.htm I display the v.PDL variable as follows...
<!-- Net:v:PDL -->
It does display the correct contents of my PDL variable, but am I just lucky that my calling NetwebSource hasn't terminate in the meantime and my v:PDL variable is still valid?
Or remains my NetwebSource in memory until my complete page is send to the browser?
regards
Patrick De Laet
PS: the underscore procedure ...
_ Procedure(prmString)
Code
packet = clip(packet) & '<13,10>' & prmString

Web Server - Ask For Help / A SendPacket for every line: is this OK?
« on: March 18, 2012, 11:24:28 AM »
Bruce,
In order to make my source a little bit readable, I created a procedure (named _ yes, underscore). Just like the "echo()" in PHP.
Why underscore? It is less "polution" in my source and makes the HTML very readable.
To send some HTML, I have the following in my source:
_('<OL>')
_('<LI>This line one</LI>')
_('<LI>This line two</LI>')
_('<LI>This line three</LI>')
_('</OL>')
The procedure is as follows:
_ Procedure(prmString)
Code
packet = clip(packet) & '<13,10>' & prmString
Do SendPacket
Return
Is this good practice?
Or does frequently calling the "Do SendPacket" generates extra overhead?

Web Server - Ask For Help / HOW TO: parse my Javascript files for Net:v:xxxx ?
« on: January 08, 2012, 04:24:21 AM »
(Using NetTalk 5.45)
I load a Javascript file via the normal <script tag in the HEAD of my page.
I'd like to replace some variables in my Javascript.
eg: to specify the open tab in my JQuery accordion.
But, apparently, my <!-- Net:v:xxxx --> tags are not parsed for my Javascript files.
Anybody an idea how to do this?
regards
Patrick De Laet
<!-- NetWebServer -->
var jQueryAccordion1Opts = {
active: <!-- Net:v:level3 -->,
autoHeight: true,
clearStyle: false,
event: 'click',
animated: 'slide',
header: 'h3',
fillSpace: false,
navigation: false
};

Web Server - Ask For Help / Where to set charset in ReplyContentType for Ajax calls?
« on: January 07, 2012, 11:12:03 AM »
(Nettalk 5.45.)
I have problems with French characters (like "bébé" or "garçon").
A GET of a normal HTML page works OK.
But my Ajax calls translate the é, ç, ... to some weird characters.
When I change NetWeb.clw as follows, it works.
But of course, I don't want to change the NetWeb.clw source.
I tried several overrides in several embeds (eg CreateHeader, ParseHTML, ...), no result.
Anybody an idea.
ParseHTML
If self.RequestAjax = 1
self.ReplyContentType = 'text/xml; charset=iso-8859-1'
! this was the original ==> - self.ReplyContentType = 'text/xml'
end

Web Server - Ask For Help / AJAX needs SESSIONID Cookie but it isn't send by the browser
« on: December 31, 2011, 06:45:51 AM »
Another problem with Cookies.
I use a lot of AJAX POSTs.
In the ProcessRequest method, it is stated that AJAX needs a Cookie . . .
! Ajax requests must have a session ID set in a cookie, otherwise nothing is returned
! This is to prevent Javascript hacking as per http://www.fortifysoftware.com/advisory.jsp
! NOTE: NetTalk uses Rico which is not vunerable to Javascript Hacking, but
If self.RequestAjax = 1 and self.SessionID = 0
! ignore ajax requests that do not include a SessionID in the cookie.
return
End
However, according to Wikepedia, Cookies are only be sent back to the server for the given domain and path.
When I enter my site via www.xprodin.be - a Cookie is created with path=/.
However, as I have 10000 SEO friendly pages (eg: www.xprodin.be/ladies/trousers/product1) Google has picked them up very nicely.
When I do a search in Google for "xprodin ladies trousers" it shows my page.
However, clicking to the Google URL for my page, brings me directly to www.xprodin.be/ladies/trousers/product1.
As this is the first visit to www.xprodin.be, a SetCookie is done for my new SESSIONID, BUT IN THE PATH=/ladies/trousers/.
That's why I have 5,6,7, ... SESSIONID Cookies.
However, when I go to my order page, www.xprodin.be/order and start an AJAX order request; my SESSIONID is not send to the server because of a different Cookie path.
No Cookie ==> AJAX does nothing. So my shopping cart doesn't work.
When I enter my site via www.xprodin.be - a cookie is created in the Path=/ - the same path as my order page ==> hence the SESSION ID cookie is send with the AJAX call and everything works.
My question: who is adding the page=/xxx/yyy stuff when creating my SESSIONID cookie? If all of my 10000 pages created a single cookie with path=/ - this would solve my problem.
But I can't find where to change this.
Maybe this behaviour has to do with my previous thread where SetCookie has 7 parameters in the prototype but use 8 parameters in the code?

Web Server - Ask For Help / Multiple SessionID session variables in my cookies?
« on: December 16, 2011, 10:56:38 AM »
NetTalk 4.43.
I have problems Setting and Getting values from my SessionQueue.
When I check my cookies, I find out that I have 6,7, even 9 SESSIONID cookies for my website?
Everytime I refresh my page, I get a new SessionID.
I'm using File Name Redirection as explained in the NetTalk book.
I'm using the _SendFilemethod in the WebHandler procedure.
I only have 1 page: www.xprodin.be/index.html, but in the _SendFile embed I'll change the pagename to www.xprodin.be/trousers/ladies or www.xprodin.be/trousers/men, ...
It seems as a SessionID cookie is created for every page?

Web Server - Ask For Help / HOW TO: unescape a URL part?
« on: December 07, 2011, 11:05:43 AM »
My URL contains my product categoriees in some part of the URL.
eg: http://81.83.9.39:88/nl/produkten/luchtwegen/a%C3%ABrosol/1 is in the URL but my productcategory is 'äerosol'.
In my webserver, I'll extract the productcategories from the URL in order to do a SQL SELECT * WHERE PRODUCTCATEGORIES = 'äerosol'
But this never returns any rows because my productcategory is encoded in the URL ('a%C3%ABrosol')
How do I decode 'a%C3%ABrosol' to 'äerosol'?
PS: I also have StringTheory - maybe there is a method to do it?

Web Server - Ask For Help / AJAX request doesn't work in Chrome
« on: June 22, 2011, 06:07:46 AM »
JQuery Form plugin
It works in FireFox but in Google Chrome my request keeps pending and I don't get any respone.
It is just a Netwebpage procedure that returns an XML response with "do sendpacket".
The XML is correct, as I can see in FireFox.
I tried async: false and async: true . . . still not working in Chrome.
$("#form1").ajaxForm({
url: 'doregistreren',
type: 'get',
data: '{}',
async: false,
target: '#message1',
dataType: 'xml',
replaceTarget: false,
success: showResponse,
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert('status:' + XMLHttpRequest.status);
alert('responseText:' + XMLHttpRequest.responseText);

Web Server - Ask For Help / AJAX request always sets text/xml in ReplyContentType
