I would like to send UDP messages to my InfluxDB server using asyncio. This is my synchronous code:
import socket
import requests
from logger import get_logger
log = get_logger(__name__)
class InfluxDB(object):
def __init__(self, username, password, host, port, udp=True, udp_port=4444):
log.info("InfluxDBClient()")
self.udp = udp
if self.udp:
self.udp_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
self.udp_port_tuple = (host, udp_port)
self.session = requests.session()
self.session.auth = (username, password)
self.base_url = "http://{}:{}".format(host, port)
def _query(self, payload, endpoint="/query"):
log.debug(payload)
return self.session.post(self.base_url + endpoint, params=payload)
def _write(self, db, data, endpoint="/write"):
log.debug("{} \t {}".format(db, data))
return self.session.post(self.base_url + endpoint, params={"db": db}, data=data)
def write_udp(self, data_str):
if self.udp:
return self.udp_socket.sendto(data_str.encode("utf-8"), self.udp_port_tuple)
else:
raise Exception("UDP disabled")
How do I rewrite the "write_udp" function using the async/await syntax?

To be more specific, I am unsure how to reference the asyncio equivalent of "socket". Presumably there is a version of an asyncio based socket, which I would reference as self.udp_socket = socket.socket_asyncio, and then I would fire off messages via await socket.socket_asyncio.sendto(....) what I need to understand is how to reference this asyncio based socket object.
