This module contains the constant enumeration for HTTP Method, which is automatically generated from pcapkit.vendor.http.method.Method.

class pcapkit.const.http.method.Method(*values)

Bases: EnumRegistry, StrEnum

[Method] HTTP Method

Note

Neither _missing_ nor get() mints any more. The owner ruled on GitHub issue #860 that get should not mint: only IANA-registered values are legitimate members, a new one is properly created through register(), and get is not given enough information to create one. Concretely true here – a bare wire method verb carries no safe/idempotent, so minting one used to register a permanent member with both hollowed out to their defaults; register() is the path that can actually supply them.

safe: bool

Safe method.

idempotent: bool

classmethod _unregistered_member(value, name)

Build a member absent from this registry’s own lookup tables.

Leaves safe and idempotent at the same defaults __new__() itself would, rather than missing entirely – _unregistered_member() bypasses __new__() (it calls str’s directly), so those two attributes would otherwise be absent. There is no more specific value to reconstruct them from – a bare wire method verb carries neither, which is exactly the owner’s reasoning for why get()/_missing_ must not mint one: register() is the path that can actually supply them.

Parameters:

• value (str) –

  Value to get enum item – the convention here, shared with FEATCode and Command, is the caller’s own casing, unchanged: an unregistered member’s value is exactly what was observed on the wire, matching how a registered member’s own value is exactly what was declared, never reformatted. Only name – the identifier, not the value – is canonicalised.

  A registered member of this class used to carry something different here: GitHub issue #870 found that __new__() called str.__new__(cls) with no argument at all, so every one of the 40 declared members’ own str payload was permanently empty regardless of value (str(Method.GET) == '', and Method.GET == 'GET' was False) – true on main at 60b85e3a4 as well as when this docstring was first written. #870 fixed __new__() to str.__new__(cls, value), mirroring Command’s own __new__, so a registered member’s payload now agrees with an unregistered member built through this method: both carry their own value as real str content (str(Method('frob')) == 'frob').

• name (str) – Bare label for the unregistered member – here, the canonical upper-case form of value, matching the name every registered member of this class is looked up by, since #860’s open-vocabulary registries have no manufactured placeholder label to fall back to.

Return type:

Method

classmethod _missing_(value)

Lookup function used when value is not found.

Parameters:

value (str) – Value to get enum item. Matched case-insensitively against the canonical upper-case member names – deliberately unlike get(), which is case-sensitive per RFC 9110 Section 9.1. The split was ruled deliberate on GitHub issue #896; GitHub issue #908 is the pointer between the two, so a reader of this one file is not left with two contradictory rationales and nothing tying them together.

Return type:

Method

static _generate_next_value_(name, start, count, last_values)

Return the lower-cased version of the member name.

classmethod _unregistered_member(value, name)

Build a member absent from this registry’s own lookup tables.

Reconstructs message the same way __new__() would, rather than leaving it unset – _unregistered_member() bypasses __new__() entirely (it calls int’s directly), so message would otherwise be missing from the result and __str__() would raise on it.

Parameters:

• value (int) – Value to get enum item.

• name (str) – Bare label for the unregistered member, per the ranged mint/unmint criterion.

Return type:

StatusCode

classmethod _missing_(value)

Lookup function used when value is not found.

Parameters:

value (int) – Value to get enum item.

Return type:

StatusCode
