Urllib3
urllib3 is a Python HTTP client library used to send network requests and receive responses. It provides core components for managing HTTP connection pools, routing traffic through proxies, validating TLS certificates, and executing automatic request retries.
The library focuses on network reliability and efficiency by maintaining a system that reuses established connections to multiple hosts to reduce latency. It ensures secure communication through client-side certificate verification and handles transient network errors using policy-based retry logic.
The project covers broad networking capabilities including the formatting of multipart-encoded payloads, stream-based response decompression, and support for both HTTP and SOCKS proxy servers.
Features
- HTTP Networking Foundations - Provides foundational HTTP networking capabilities for sending requests and handling responses within Python.
- Request Retries - Provides mechanisms for automatically re-attempting failed network requests to improve overall system reliability.
- Automatic Retry Clients - Ships a client that automatically retries failed requests with configurable limits, delays, and jitter.
- API Request Execution - Executes network requests to remote servers to retrieve data and status codes for application logic.
- HTTP Connection Pools - Manages reusable HTTP connection pools to reduce latency and overhead during repeated requests.
- HTTP Client Libraries - Provides a comprehensive library for performing synchronous and asynchronous HTTP requests in Python.
- Traffic Routing Proxies - Provides built-in support for routing network requests through HTTP and SOCKS proxy servers to bypass restrictions or manage connection paths.
- Retry Policies - Implements mechanisms for automatically retrying failed network requests based on status codes and backoff strategies.
- Certificate Verification - Validates SSL/TLS certificates during network requests to ensure server authenticity.
- TLS Certificate Validations - Validates server certificates during the TLS handshake to prevent man-in-the-middle attacks.
- Server Identity Verification - Authenticates remote server identities using certificates to prevent impersonation and ensure secure communication.
- SSL Certificate Validations - Verifies server identities using security certificates to ensure secure and encrypted communication.
- Response Decompression - Automatically decompresses HTTP response bodies using various standard encoding formats.
- HTTP Proxies - Acts as an intermediary for HTTP requests by routing traffic through HTTP and SOCKS proxy servers.
- Multipart Form Encoding - Serializes binary files and text fields into a single stream using boundary markers for HTTP uploads.
- Multipart Form Uploads - Provides capabilities for transmitting files and binary data using the HTTP multipart/form-data encoding standard.
- Proxy Server Routing - Routes network traffic through proxy servers to bypass restrictions or mask origin identities.
- Proxy Routing - Routes outgoing network traffic through intermediate HTTP or SOCKS proxy servers.
- HTTP Clients - HTTP library with thread-safe connection pooling.
