RetryHTTP

Retry potentially transient HTTP errors in Python.

See documentation.

Overview

Several HTTP errors are often transient, and might succeed if retried:

• HTTP status codes
  • 429 Too Many Requests (rate limited)
  • 500 Internal Server Error
  • 502 Bad Gateway
  • 503 Service Unavailable
  • 504 Gateway Timeout
• Network errors
• Timeouts

This project aims to simplify retrying these, by extending tenacity with custom retry and wait strategies, as well as a custom decorator. Defaults are sensible for most use cases, but are fully customizable.

Supports exceptions raised by both requests and httpx.

Install

Install from PyPI:

# Supports both HTTPX and requests
pip install retryhttp

You can also install support for only HTTPX or requests:

pip install retryhttp[httpx] # Supports only HTTPX
pip install retryhttp[requests] # Supports only requests

Or, install the latest development snapshot from git:

pip install git+https://github.com/austind/retryhttp.git@develop

Quickstart

import httpx
from retryhttp import retry

# Retries retryable status codes (429, 500, 502, 503, 504), network errors,
# and timeouts, up to 3 times, with appropriate wait strategies for each
# type of error. All of these behaviors are customizable.

def example():
    response = httpx.get("https://example.com/")
    response.raise_for_status()
    return response.text
