Google & Rest

• REST – Representational State Transfer• Architectural style for web service• Google says “REST is simple, lightweight, scalable,

and maps very well to representing and exposing data.”

• Is it REST? – Joe Gregorio (XML.com)

– What are the URIs?– What methods are supported at each URI?– What’s the format?– What status codes could be returned?

A Google Demo

• POST/GET Calendar• Chunky Not Chatty• Take what you want• Chunked Results

Http response code & Exceptions

HttpWebResponse response = authResponse as HttpWebResponse; if (response != null) { int code= (int)response.StatusCode; if (code != 200) { throw new GDataRequestException("Execution of

authentication request returned unexpected result: " +code, this.Response);

}

SLAService Level Questions

Statefulness When you use SOAP to set a server value, does the server respond correctly in the subsequent states?

Access Can an unauthorized user successfully access a control that only the administrators are authorized to use?

Response time Is the Web service taking too long to respond (for example, more than 10 seconds)?

Time-out What happens when the Web service times out?

Versioning Can a new build break an existing Web service's functions?

Have we learned anything from this?
