socket ( family = AF_INET, type = SOCK_STREAM, proto = 0, fileno = None ) ¶Ĭreate a new socket using the given address family, socket type and protocol The following functions all create socket objects. HCI_DATA_DIR are not available for FreeBSD, NetBSD, orĬonstant for Qualcomm’s IPC router protocol, used to communicate withĪvailability: Linux >= 4.7. HCI_FILTER is notĪvailable for NetBSD or DragonFlyBSD. For example, BDADDR_ANY can be used to indicateĪny address when specifying the binding socket withīTPROTO_RFCOMM.

These are string constants containing Bluetooth addresses with special
This constant contains a boolean value which indicates if IPv6 is supported on The tuple can be used if IDĪnd unit number of the kernel control are known or if a registered ID is Kernel control using a dynamically-assigned ID. (PGN), and an 8-bit integer representing the address.Ī string or a tuple (id, unit) is used for the SYSPROTO_CONTROL Where additional parameters are 64-bit unsigned integer representing theĮCU name, a 32-bit unsigned integer representing the Parameter Group Number Where both additional parameters are unsigned long integer that represent aĬAN_J1939 protocol require a tuple (interface, name, pgn, addr) The network interface name '' can be used to receive packetsįrom all network interfaces of this family.ĬAN_ISOTP protocol require a tuple (interface, rx_addr, tx_addr) Where interface is a string representing a network interface name like
If addr_type is TIPC_ADDR_ID, then v1 is the node, v2 is theĪ tuple (interface, ) is used for the AF_CAN address family, Is the lower port number, and v3 is the upper port number. If addr_type is TIPC_ADDR_NAMESEQ, then v1 is the server type, v2 If addr_type is TIPC_ADDR_NAME, then v1 is the server type, v2 is Scope is one of TIPC_ZONE_SCOPE, TIPC_CLUSTER_SCOPE, and (addr_type, v1, v2, v3 ), where:Īddr_type is one of TIPC_ADDR_NAMESEQ, TIPC_ADDR_NAME,
Tuple, and the fields depend on the address type. TIPC is an open, non-IP based networked protocol designedįor use in clustered computer environments. Linux-only support for TIPC is available using the AF_TIPCĪddress family. This information is superfluous and mayĪF_NETLINK sockets are represented as pairs (pid, groups). Note, however, omission of scope_id can cause problemsĬhanged in version 3.7: For multicast addresses (with scope_id meaningful) address may not contain Socket module methods, flowinfo and scope_id can be omitted just forīackward compatibility. Therefore, you may want to avoid these if you intend to support IPv6 with yourįor AF_INET6 address family, a four-tuple (host, port, flowinfo, scope_id) is used, where flowinfo and scope_id represent the sin6_flowinfoĪnd sin6_scope_id members in struct sockaddr_in6 in C. This behavior is not compatible with IPv6, Notation like '' or an IPv4 address like '100.50.200.5',įor IPv4 addresses, two special forms are accepted instead of a hostĪddress: '' represents INADDR_ANY, which is used to bind to all Where host is a string representing either a hostname in internet domain Changed in version 3.5: Writable bytes-like object is now accepted.Ī pair (host, port) is used for the AF_INET address family, send ( message ) async def main (): async with serve ( echo, "localhost", 8765 ): await asyncio. run ( hello ( "ws://localhost:8765" ))Īnd here’s an echo server: #!/usr/bin/env python import asyncio from websockets import serve async def echo ( websocket ): async for message in websocket : await websocket. Here’s how a client sends and receives messages: #!/usr/bin/env python import asyncio from websockets import connect async def hello ( uri ): async with connect ( uri ) as websocket : await websocket. With a focus on correctness, simplicity, robustness, and performance.īuilt on top of asyncio, Python’s standard asynchronous I/O framework, itĭocumentation is available on Read the Docs. Websockets is a library for building WebSocket servers and clients in Python
