  • Builds Reusable Objects for Consuming Web APIs.
  • Works with Requests, aiohttp, and Twisted.
  • Inspired by Retrofit <http://square.github.io/retrofit/>__.

A Quick Walkthrough, with GitHub API v3

Uplink turns your HTTP API into a Python class.

… code-block:: python

from uplink import Consumer, get, Path, Query

class GitHub(Consumer):
“”“A Python Client for the GitHub API.”“”

   @get("users/{user}/repos")
   def get_repos(self, user: Path, sort_by: Query("sort")):
       """Retrieves the user's public repositories."""

Build an instance to interact with the webservice.

… code-block:: python

github = GitHub(base_url=“https://api.github.com/”)

Then, executing an HTTP request is as simply as invoking a method.

… code-block:: python

repos = github.get_repos(user=“octocat”, sort_by=“created”)

The returned object is a friendly |requests.Response|_:

… |requests.Response| replace:: requests.Response
… _requests.Response: http://docs.python-requests.org/en/master/api/#requests.Response

… code-block:: python

print(repos.json())

Output: [{‘id’: 64778136, ‘name’: ‘linguist’, …

For sending non-blocking requests, Uplink comes with support for
|aiohttp and twisted|_.

… |aiohttp and twisted| replace:: aiohttp and twisted

Features

  • Quickly Define Structured API Clients

    • Use decorators and type hints to describe each HTTP request
    • JSON, URL-encoded, and multipart request body and file upload
    • URL parameter replacement, request headers, and query parameter support

  • Bring Your Own HTTP Library

    • Non-blocking I/O support_ for Aiohttp and Twisted
    • Supply your own session_ (e.g., requests.Session) for greater control

  • Easy and Transparent Deserialization/Serialization

    • Define custom converters_ for your own objects
    • Support for |marshmallow|_ schemas, |pydantic|_ models, and handling collections_ (e.g., list of Users)

  • Extendable

    • Install optional plugins for additional features (e.g., protobuf support_)
    • Compose custom response and error handling_ functions as middleware

  • Authentication

    • Built-in support for Basic Authentication_
    • Use existing auth libraries for supported clients (e.g., |requests-oauthlib|_)

Uplink officially supports Python 2.7 and 3.5+.

Note: Python 2.7 suport will be removed in v0.10.0.

User Testimonials

Michael Kennedy (@mkennedy), host of Talk Python and Python Bytes_ podcasts-

Of course our first reaction when consuming HTTP resources in Python is to
reach for Requests. But for *structured* APIs, we often want more than ad-hoc
calls to Requests. We want a client-side API for our apps. Uplink is
the quickest and simplest way to build just that client-side API.
Highly recommended.

Or Carmi (@liiight), notifiers maintainer-

Uplink's intelligent usage of decorators and typing leverages the most
pythonic features in an elegant and dynamic way. If you need to create an
API abstraction layer, there is really no reason to look elsewhere.
