带有回调请求的简单异步 python 3

Question

我是 python 的新手我正在尝试开发发送大约 10,000 个请求来测试我的 API 的应用程序，我使用 pyqt5 和 python 3，我想要使用请求发出许多异步请求，发送许多请求而不是等待响应，而是在响应准备好时添加回调例如更新UI，请给我一个工作示例，谢谢帮助

您好 furas 试试您的代码，无需向 session.post 添加代理即可运行，这是代码

import aiohttp
import asyncio
import sys
import time
from decimal import localcontext, Decimal, ROUND_HALF_UP
from datetime import datetime,timezone ,timedelta
BASE_URI = 'https://d.com/session.php'

def show_exception_and_exit(exc_type, exc_value, tb):
        traceback.print_exception(exc_type, exc_value, tb)
        sys.exit(-1)


async def fetch(session, url):
    proxies = {
        "http"  :"http://W09s1H:eMwmFL@91.188.240.67:9951",
        "https" :"https://W09s1H:eMwmFL@91.188.240.67:9951"
        }
    Timestamp = int((datetime.utcnow() - datetime(1970,1,1)).total_seconds())
    headers = {
        "user-agent": "Mozilla/5.0 (X11; Linux i686; rv:64.0) Gecko/20100101 Firefox/64.0"
        }
    JsonSession = "{'device':'id'}"

    async with session.post(url,
                            data=JsonSession,
                            headers=headers,
                            params={"timestamp":Timestamp}) as response:
        return await response.text()

async def main(url):
    tasks = []
    results = []
    async with aiohttp.ClientSession() as session:
        for n  in range(1,10):
            tasks.append(fetch(session, url))
        results = await asyncio.gather(*tasks)
    return results

def parallel(url):
    loop = asyncio.get_event_loop()
    results = loop.run_until_complete(main(url))
    return results

# --- main ---



result = parallel(BASE_URI)

for item in result:
    print(item[:300])
    print('-----')

当我像这样添加代理时：

 async with session.post(url,
                            data=JsonSession,
                            headers=headers,
                            params={"timestamp":Timestamp},
                            proxies=proxies) as response:

我收到错误

Traceback (most recent call last):
  File "C:/Users/soft/AppData/Local/Programs/Python/Python37-32/MyApp/Scripts/Test.py", line 51, in <module>
    result = parallel(BASE_URI)
  File "C:/Users/soft/AppData/Local/Programs/Python/Python37-32/MyApp/Scripts/Test.py", line 44, in parallel
    results = loop.run_until_complete(main(url))
  File "C:\Users\soft\AppData\Local\Programs\Python\Python37-32\lib\asyncio\base_events.py", line 579, in run_until_complete
    return future.result()
  File "C:/Users/soft/AppData/Local/Programs/Python/Python37-32/MyApp/Scripts/Test.py", line 39, in main
    results = await asyncio.gather(*tasks)
  File "C:/Users/soft/AppData/Local/Programs/Python/Python37-32/MyApp/Scripts/Test.py", line 30, in fetch
    proxies=proxies) as response:
  File "C:\Users\soft\AppData\Local\Programs\Python\Python37-32\lib\site-packages\aiohttp\client.py", line 876, in post
    **kwargs))
TypeError: _request() got an unexpected keyword argument 'proxies'

如何将代理添加到 session.post 因为我确实需要添加它
