aiohttp：未关闭的客户端会话 client_session答案

【问题标题】：aiohttp: Unclosed client session client_sessionaiohttp：未关闭的客户端会话 client_session
【发布时间】：2019-02-21 12:54:45
【问题描述】：

我有一个test.py 文件和一个AsyncioCurl.py 文件。
我已经使用session 而不仅仅是aiohttp.request
但它也给了我这个错误：

Unclosed client session
client_session: <aiohttp.client.ClientSession object at 0x000001FAEFEA7DA0>
Unclosed connector
connections: ['[(<aiohttp.client_proto.ResponseHandler object at 0x000001FAF10AC648>, 119890.906)]']
connector: <aiohttp.connector.TCPConnector object at 0x000001FAF0F702B0>

test.py

import asyncio
from AsyncioCurl import AsyncioCurl
async def a():
    payload = {}
    url = "https://awebsiteisthere.com"
    data = await AsyncioCurl().get(url,payload)
    print(data)

task = [
    a()
]

loop = asyncio.get_event_loop()
loop.run_until_complete(asyncio.wait(task))

AsyncioCurl.py

import asyncio
import aiohttp
from Log import Log
from Base import sign

class AsyncioCurl:
    def __init__(self):
        self.session = aiohttp.ClientSession(timeout=aiohttp.ClientTimeout(total=4))

    async def get(self,url,param):
        Log.debug("GET: "+url)
        payload = {
            "cookie":config["Token"]["COOKIE"]
        }
        payload = dict(param,**payload)
        payload = sign(payload)
        async with self.session.get(url,params=payload) as r:
            Log.debug(r.status)
            return await r.json()

    async def post(self,url,param):

            }
            payload = dict(param,**payload)
            payload = sign(payload)
            async with self.session.post(url,data=payload) as r:
                return await r.json()

    async def nspost(self,url,param):

【解决方案1】：

这不是错误，只是警告。您可以通过关闭会话来处理它。试试这个：

async def a():
    payload = {}
    url = "https://awebsiteisthere.com"
    curl = AsyncioCurl()
    data = await curl.get(url,payload)
    print(data)
    await curl.session.close()  # this

【讨论】：

对我来说 await curl.close() #without session 完成了这项工作

【解决方案2】：

我刚刚在您的test.pyscript 末尾添加了close()

import asyncio
from AsyncioCurl import AsyncioCurl
async def a():
    payload = {}
    url = "https://awebsiteisthere.com"
    data = await AsyncioCurl().get(url,payload)
    print(data)
    await AsyncioCurl.close() #added this line

task = [
    a()
]

loop = asyncio.get_event_loop()
loop.run_until_complete(asyncio.wait(task))
