AIOHTTP:客户机示例

Question

我刚在我的mac上安装了AIOHTTP

Python 3.10.8

Visual代码版本: 1.72.2

Package            Version
------------------ -------
aiodns             3.0.0
aiohttp            3.8.3
aiosignal          1.2.0
async-timeout      4.0.2
attrs              22.1.0
cffi               1.15.1
charset-normalizer 2.1.1
frozenlist         1.3.1
idna               3.4
multidict          6.0.2
pip                22.3
pycares            4.2.2
pycparser          2.21
setuptools         65.5.0
wheel              0.37.1
yarl               1.8.1

例如。代码

import aiohttp
import asyncio

async def main():

    async with aiohttp.ClientSession() as session:
        async with session.get('http://python.org') as response:

            print("Status:", response.status)
            print("Content-type:", response.headers['content-type'])

            html = await response.text()
            print("Body:", html[:15], "...")

loop = asyncio.get_event_loop()
loop.run_until_complete(main())

当我试图运行客户端示例之上的代码时，我得到了很多错误，这只是其中的几个。我错过了什么？

test.py:15: DeprecationWarning: There is no current event loop
  loop = asyncio.get_event_loop()
Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages/aiohttp/connector.py", line 980, in _wrap_create_connection
    return await self._loop.create_connection(*args, **kwargs)  # type: ignore[return-value]  # noqa

raise ClientConnectorCertificateError(req.connection_key, exc) from exc
aiohttp.client_exceptions.ClientConnectorCertificateError: Cannot connect to host python.org:443 ssl:True [SSLCertVerificationError: (1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate 

Answer 1

根据这的说法，

session = aiohhtp.ClientSession(connector=aiohttp.TCPConnector(verify_ssl=False))

这与verify=False库中的requests类似。

Answer 2

我找到了答案。入门客户端示例不适用于3.10.

在3.9到3.10之间切换是复制错误的简单方法.
