URL - Uniform Resource Locator
Fundamental importance of the URI/URL
URI = “Uniform Resource Identifier”
Used to be called “Universal Resource Locator” (URL)
Because the resources were files on the disk of the server
And the URL’s path was really a path!
Focus now on the ‘path’ part of the URI
e.g. some ugly examples
http://roomscheduler.com/reserve/room/3
http://bookstore/gonewiththewind/order/3
http://nyt.com/latest-updates?year=2014
e.g. some good examples
http://roomscheduler.com/room/3/request
http://bookstore.com/book/412/price
http://tourmanager.com/city/boston/tour/tuesday/new
There are many ways to structure a url
RESTful style of URI design
“Representational State Transfer” (See
Original REST Paper
)
Each URI denotes a specific ‘resource’
‘room 3’ or ‘book 412’ or ‘tuesday tours IN Boston city’
It is usually not a file but something generated ‘on the fly’
Still the same URI should yield the same resource every time (handwave)
Each URI is used in combination with an HTTP “method”
Get: retrieve the indicated “resource”
Put: update value of the indicated resource
Delete: delete the indicated resource
Post: Create a new instance of indicated resource
(some other, less important ones)
One of the earliest design questions
What do the URLs for my app look like?
Conceptually, they are “directory structure-like” URLs
There is a coherent “syntax” about them, e.g.
http://www.myservice.org/discussion/topics/{topic}
http://www.myservice.org/discussion/2008/12/10/{topic}
http://www.myservice.org/discussion/{year}/{day}/{month}/{topic}
