Pure Python RFC 3986 Validator

Warnings

• gotcha This library is classified as '2 - Pre-Alpha' and has not seen updates since October 2019. Its long-term maintenance and compatibility with newer Python versions (beyond 3.8) are uncertain.
  Fix: For actively maintained and feature-rich RFC 3986 validation, parsing, and building capabilities, consider using the `rfc3986` library (without the '-validator' suffix) which is at version 2.0.0 and actively developed.
• gotcha The `rfc3986-validator` library provides a single `validate_rfc3986` function for basic URI validation. It does not offer granular control over URI components (like scheme, host, path, query) or methods for constructing URIs.
  Fix: If your application requires more advanced URI handling, such as parsing components, building URIs, or custom validation rules (e.g., allowing only specific schemes or hosts), the `rfc3986` library offers `uri_reference`, `urlparse`, `validators.Validator` classes, and `URIBuilder` for these purposes.

Quickstart

The `validate_rfc3986` function checks if a given string conforms to the RFC 3986 URI syntax. It can also validate against specific rules like 'URI_reference'.

from rfc3986_validator import validate_rfc3986

# Validate a full URI
print(validate_rfc3986('http://example.com/path?query=val#fragment')) # Expected: True

# Validate a URI reference (e.g., relative path)
print(validate_rfc3986('//example.com/path', rule='URI_reference')) # Expected: True

# Example of an invalid URI
print(validate_rfc3986('http://foo.bar?q=Spaces should be encoded')) # Expected: False
