Hello all,
I'm planning to teach my students how to post data to web servers
and get back results in their stacks. I've got a couple of examples,
but I wonder if anyone could point me to some examples that would be
simple enough for beginners. I'm thinking of things like doing a
Google search from a stack, looking up a weather report, getting
local movie information, etc.
I don't have any examples handy since I post to my own data processing
servers from Rev, but here is an idea.
Most web forms use the POST method and you can find out by looking at
the source where it will specify either GET or POST.
The GET method, of course means the name=value pairs are added to the
url.
"http://www.google.com?q=desert+oasis&language=EN";
The POST method sends the name=value pairs in a data packet that is
invisible.
The form uses the names of the input fields/buttons/ckboxes and their
values to prepare the data packet.
So, find forms that use 'POST', note the field names, and make your
own Rev post (name=value&name=value)
If a web page form is programmed for GET, then it likely will ignore
incoming POST commands.
Thanks, Jim. Great advice, and perhaps a logical instructional
progression starting with showing how GET urls work then moving to
POSTing to a URL.
