"""
A simple wrapper for a RESTful api, which returns the parsed json response
as an object.

Example:

  # Request the post with id #1 and the comments for it at
  # jsonplaceholder.typicode.com

  api = RESTful("jsonplaceholder.typicode.com", protocol="https")

  # Get a list of posts as dictionaries ( [{...},...] )
  posts = api.query("/posts")

  # Get post id #1 as a dictionary of properties ( {'body':..., ...})
  post = api.query("/posts/1")

  # Get the comments on post #1 as a list of dictionaries.
  cmts = api.query("/posts/1/comments")  # => ditto

  # Simulate posting our own post.
  post = api.query("/posts", body={"userId":123, "title":"Test Post",
          "body":"This is a test, just a test."})

For some interfaces you will need to use 'put' rather than 'post', in which
case there is an "update" rather than "query" member:

  post = api.update("/posts", body={"userId":123, "title":"Test Post"})


You can use "prefix" to create API-zoned objects:

  class PostsAPI(RESTful):
    DEFAULT_PROTOCOL = "https"
    DEFAULT_PREFIX   = "/posts"

  posts = PostsAPI("jsonplaceholder.typicode.com")
  posts.query()  # Returns list of posts
  posts.query("1")  # Returns /posts/1  =>  dictionary of post 1 properties
