httparse

Python wrapper for Rust's httparse. See this project on GitHub.

Example

from httparse import RequestParser

parser = RequestParser()

buff = b"GET /index.html HTTP/1.1\r\nHost"
parsed = parser.parse(buff)
assert parsed is None

# a partial request, so we try again once we have more data
buff = b"GET /index.html HTTP/1.1\r\nHost: example.domain\r\n\r\n"
parsed = parser.parse(buff)
assert parsed is not None
assert parsed.method == "GET"
assert parsed.path == "/index.html"
assert parsed.version == 1
assert parsed.body_start_offset == len(buff)
headers = [(h.name.encode(), h.value) for h in parsed.headers]
assert headers == [(b"Host", b"example.domain")]
