json-paginator

A generator for iterating over paginated JSON API responses

Installation

pip install json-paginator

Usage

Instantiate JsonApiPaginator with:

• A URL to page 1 of the API output
• A function (or lambda) get_nextpage(url, body) which describes how to get the next page. Return None to stop iteration.

Example:

from json_paginator import JsonApiPaginator

BASE = 'https://galaxy.ansible.com'

def get_next_page(url, body):
    if body['next_link']:
        return BASE +  body['next_link']
    return None

# instantiate the paginator
pages = JsonApiPaginator(
    BASE + '/api/v1/categories/?page=1',
    get_next_page
)

# iterate over the pages
for url, body in pages:
    print("calling %s" % (url))
    print("found %s results" % (len(body['results'])))
