http-utils 0.1.5

Utils for HTTP requests using the requests library

Http Utils

A simple requests session wrapper.

Installation

pip install pip install git+git://github.com/juntossomosmais/http-utils.git

Configuration process

If needed you can provide some settings as environment variables.

HTTP_RETRIES=3
HTTP_BACKOFF_FACTOR=0.1
HTTP_STATUS_FORCELIST=
HTTP_TIMEOUT=30

Usage

The basic usage is to call the request_session as a context manager.

from http_utils.session import request_session


def awesome_request():
    with request_session() as request:
        response = request.get(url="https://www.some-awesome-service.com")
    return response

This will add:

• A retry mechanism of 3 attempts for status codes (defined in the HTTP_RETRIES variable or as the total parameter)
• A backoff factor for each retry in seconds (defined in the HTTP_BACKOFF_FACTOR variable or as the backoff_factor parameter)
• A list of status to force retries (defined in the HTTP_STATUS_FORCELIST variable or as the status_forcelist parameter)
• A list of allowed methods to request (Defined as ["HEAD", "GET", "PUT", "DELETE", "OPTIONS", "TRACE"] methods by default or as the allowed_methods parameter)
• A list of hooks (The default hooks used are the raise_for_status and a DEBUG level log for the response body, header and status code)

Helpers

There are also some helper functions that can be used to parse the response object

• get_response_body: Attemps to return a parsed json response body, returning the response text if it can't.

• convert_header_to_meta_key: Converts the Django Http Request META header to be separated with a - instead of _

Tests

In order to execute tests, execute the following:

docker-compose up -d tests

This will run the tests in the python 3.9.4, 3.8.5, 3.7.5, 3.6.9 tox environments
