URI

✓ from lazr.uri import URI

find_uris_in_text

✓ from lazr.uri import find_uris_in_text

Demonstrates how to parse a URI, access its components, modify it, and extract multiple URIs from a block of text.

from lazr.uri import URI, find_uris_in_text # Parsing a URI and accessing its parts uri_str = "https://www.example.com:8080/path/to/resource?query=param&key=value#fragment" uri = URI(uri_str) print(f"Scheme: {uri.scheme}") print(f"Host: {uri.host}") print(f"Port: {uri.port}") print(f"Path: {uri.path}") print(f"Query: {uri.query}") print(f"Fragment: {uri.fragment}") # Manipulating a URI new_uri = uri.replace(scheme='http', port=None) print(f"Modified URI: {new_uri}") # Finding URIs within a text block text_with_uris = "Visit our site at http://example.org or email us at mailto:support@example.net." found_uris = list(find_uris_in_text(text_with_uris)) for found_uri in found_uris: print(f"Found URI: {found_uri}")

Debug

Known issues

breakingVersion 1.0.7 dropped support for Python versions 3.7 and below.

fix

Upgrade your Python environment to version 3.8 or higher. If unable to upgrade Python, use `lazr-uri<1.0.7`.

affects: >=1.0.7

gotchaPrior to version 1.0.6, `lazr.uri`'s versioning strategy imported `pkg_resources`, which could lead to significant performance overhead in large Python environments during startup.

fix

Upgrade to `lazr-uri` version 1.0.6 or newer to benefit from the adjusted versioning strategy that avoids `pkg_resources` for better performance.

affects: <1.0.6

Errors

Common errors & fixes

ImportError: cannot import name 'URI' from 'lazr.uri' (...)

This usually indicates an outdated version of `lazr-uri` or an issue with the Python environment where a module named `lazr.uri` exists but does not contain the `URI` class, or a namespace conflict.

fix

Ensure `lazr-uri` is correctly installed and up-to-date with `pip install --upgrade lazr-uri`. Verify no other packages are conflicting with the `lazr.uri` namespace.

AttributeError: 'URI' object has no attribute 'port' (when expecting a port from a URI without one)

When a URI string does not explicitly include a port, the 'port' attribute of the `URI` object will be `None`, leading to an `AttributeError` if you try to access methods or properties directly on it without checking if it's `None`.

fix

Always check if URI components like `uri.port` are `None` before attempting operations on them. Example: `if uri.port is not None: print(uri.port)`.
