Re: Is it possible to send a call to the CGI program without

GETURI is "web sockets" but not something used in HTML or Javascript
(similar to cURL as well). Now, I know web sockets is a term used for a
cURL type request made from HTML. They all do the same thing. Just done
in different places.

I just offered a solution to the problem. Darryl mentioned the data was
from a web service, so that would be easy enough to use a sockets solution
inside of a CGI application.

A hundred ways to do that, (ie, new window, new page, ajax, etc). It all
depends on the skill set and desire.

What you are suggesting is subtly different Brad. You are talking about a
web service request that is initiated from the server-side code. That is
nothing to do with web sockets. Web sockets are a way for the browser to
have bidirectional ws conversation with a server that is not necessarily in
the same domain as the http server you are connected to. With web sockets
you can also push data to a browser without it having to have initiated the
conversation.

The crux of Darryl's problem is that the web page containing the data (and
buttons) is being delivered from a different server/domain to the one he
wants to use to action the button click.so you can only do that if the
button is going to navigate away from the original domain.

Yep, that's exactly what I suggested.

You have a link on your page (or button, etc) that links to a CGI (or
eRPG
as I like to call them) program (on your same IBMi server).

Your CGI program calls GETURI to do a sockets/web service request and
gather data from the other system. The data is returned and you parse
if,
if needed, then the CGI program returns a web page with information
regarding that. Reporting errors, or the data returned, etc.

Done it thousands of times. Fun things for sure! Especially with web
services for virtually everything these days.

Well put it this way, if you load the page (with the button) from
http://example1.com/somewhere then you cannot have a button that
interacts with http://myiseries.com/somewhereelse and then continues to
work with http://example1.com/somewhere after the button click action
is
finished. That is the illegal cross-domain request we talked about
earlier.
You can only do that if your button click is going to navigate away to
http://myiseries.com/somewhereelse completely (i.e. waving goodbye to
http://example1.com/somewhere ) The only way I know of to circumvent
this is to use web sockets to initiate the request. Without that, the
domain that delivers the list of data and the button(s) must be the same
domain as the one that processes the button request.

Clear as mud I guess...

Subject: [WEB400] Is it possible to send a call to the CGI program

Let me try and clarify this a little more.



Firstly thanks for the comments.



We use a reporting tool on the AS/400 that displays data only. In this
instance, there is a list of programs that need permission to be
promoted
into production. The manager will display the list on her screen, iPad
or
cell phone and if she approves it, she will select an approve button,
which
should then call something like a web service to process the approval.
The
button will do a "call" to a CGI program to update the new status. It
would
at that point return a confirmation screen from CGIDEV.
