http-fields
Typed, validated HTTP headers for Python. Each header is an immutable dataclass whose fields are the structured components of the header. abnf grammars are used both to parse incoming header strings and to validate field values, so a constructed header is always well-formed.
Requires Python 3.10+.
from http_fields import ContentType, Header
ct = ContentType.parse("text/html; charset=UTF-8")
ct.type, ct.subtype, ct.charset # ('text', 'html', 'UTF-8')
str(ct) # 'Content-Type: text/html;charset=UTF-8'
ContentType.of(type="text", subtype="html", charset="utf-8") # build from pieces
Header.create("x-request-id", "abc123") # dispatch by name
Install
uv add http-fields
# or: pip install http-fields
