我想使用 Telethon (Telegram bot) 和 aiopg (PostgreSQL) 库。
马拉松示例:
from telethon import TelegramClient
api_id = 12345
api_hash = '0123456789abcdef0123456789abcdef'
client = TelegramClient('anon', api_id, api_hash)
async def main():
# Getting information about yourself
me = await client.get_me()
print(me.stringify())
@client.on(events.NewMessage)
async def my_event_handler(event):
if 'hello' in event.raw_text:
await event.reply('hi!')
client.start()
client.run_until_disconnected()
aiopg 示例:
import aiopg
dsn = 'dbname=aiopg user=aiopg password=passwd host=127.0.0.1'
async def notify(conn):
async with conn.cursor() as cur:
for i in range(5):
msg = "message {}".format(i)
print('Send ->', msg)
await cur.execute("NOTIFY channel, %s", (msg,))
await cur.execute("NOTIFY channel, 'finish'")
async def listen(conn):
async with conn.cursor() as cur:
await cur.execute("LISTEN channel")
while True:
msg = await conn.notifies.get()
if msg.payload == 'finish':
return
else:
print('Receive <-', msg.payload)
async def main():
async with aiopg.create_pool(dsn) as pool:
async with pool.acquire() as conn1:
listener = listen(conn1)
async with pool.acquire() as conn2:
notifier = notify(conn2)
await asyncio.gather(listener, notifier)
print("ALL DONE")
loop = asyncio.get_event_loop()
loop.run_until_complete(main())
我想在同一个 python 脚本中使用两者。我试图找到解决方案,它可能是 asyncio.gather(...),但我不知道如何结合这两个库,如何启动两个循环。你能帮我么?
