A dumb little wrapper around RESTful interfaces
What is Dolt?
Dolt is a minimalist wrapper around RESTful interfaces, specifically, JSON RESTful interfaces. Instead of adding another layer on top of the calls, this uses Httplib2 and some Python magic to allow truly simple wrappers on top of already well thought out (at least sometimes) REST APIs.
For example, let's look at the Twitter API call for grabbing a user. We'll use my user, tswicegood
python-twitter maps that to:
twitter = twitter.Api() twitter.GetUser("tswicegood")
So where'd this come from? The creators of python-twitter. You have to read
their documentation to figure out what call to make, because the api
docs don't mention
Here's what that same call in the Twitter Dolt object as shown in the examples/ directory:
twitter = Twitter() twitter.users.show(screen_name="tswicegood")
Notice the similarities? This way, you can use the official API docs to figure out how your'e supposed to interact with the object that represents it. No extra documentation needed.
How to handle non-GET methods
Dolt can handle all sorts of methods in its requests, not just GET method requests. To do that, you have to muddy up the API call just a bit.
Here's an example making a post to update the status. First, the Twitter API:
Now the Dolt version:
twitter = Twitter() twitter.statuses.update.POST(status="Hello from Dolt!")
Notice that all you need to add to it is the method you want to call. If
you're feeling very Pythonic and want to be explicit in every call, you can add
.GET as the final method call, though that's always assumed.
Sometimes having that
PUT at the end seems weird. You can stick
the method wherever you want in the call string of properties, it just has to
be in all uppercase. For example, this works just the same as the previous
twitter = Twitter() twitter.POST.statuses.update(status="Hello from Dolt!")
This works for other HTTP methods as well, such as
Dolt relies on the httplib2 project for its underlying HTTP
requests. Httplib2 has an
add_credentials method that allows you to add
credentials to it. Dolt takes an
http parameter in its
which allows you to pass in an Http object with credentials. For example:
http = Http() http.add_credentials("some_user", "secret") some_api = Dolt(http=http)
Of course, I'm not a lawyer, so if you have questions about the licensing and how it effects your use, please consult a professional lawyer, not some random README file.
Want to help?
This is open source, so feel free to grab any of these tasks and contribute:
- Abstract away the simplejson.loads() call so you can replace it with your own functionality
- Once simplejson depedency is removed, add ability to return RemoteObjects
