I want to ask some questions about the REST call. I am the green for the REST call and I would like to like what is REST call and how to use the URL to send a REST call to the server. Can anyone give me some basic tutorial or link for my to reference?
Besides, if I want to send a REST call to the server, what should I do? Do I need to set something in the URL? or set something in the server? Thank you.
REST is just a software architecture style for exposing resources.
A typical REST call to return information about customer 34456 could look like:
http://example.com/customer/34456
Have a look at the IBM tutorial for REST web services
REST is somewhat of a revival of old-school HTTP, where the actual HTTP verbs (commands) have semantic meaning. Til recently, apps that wanted to update stuff on the server would supply a form containing an 'action' variable and a bunch of data. The HTTP command would almost always be GET or POST, and would be almost irrelevant. (Though there's almost always been a proscription against using GET for operations that have side effects, in reality a lot of apps don't care about the command used.)
With REST, you might instead PUT /profiles/cHao and send an XML or JSON representation of the profile info. (Or rather, I would -- you would have to update your own profile. :) That'd involve logging in, usually through HTTP's built-in authentication mechanisms.) In the latter case, what you want to do is specified by the URL, and the request body is just the guts of the resource involved.
http://en.wikipedia.org/wiki/Representational_State_Transfer has some details.
