英文:
requests / aiohttp with SOCKS5. 0x05: Connection refused
问题
我有两个程序版本：
- 同步版本，使用
requests库； - 异步版本，使用
aiohttp库。
需要使用 SOCKS5 代理向一个站点发起请求。在安装了与 SOCKS5 代理一起使用的必要库后，我尝试向一些站点发送请求。对于所有站点，除了必要的那个之外，一切正常运行。在向它发送请求时，出现了一个错误：
> 0x05：连接被拒绝
英文:
I have two versions of the program:
- Synchronous, using
requestslibrary; - Asynchronous, using
aiohttplibrary.
It is necessary to make requests to a site using SOCKS5 proxy. After installing the necessary libraries to work with SOCKS5 proxies, I tried making requests to a few sites. Everything worked fine with all sites except the necessary one. When sending a request to it, an error appeared:
> 0x05: Connection refused

我找到了requests库的解决方案，只用了几分钟。但是我没有找到aiohttp的解决方案，所以花了我好几个小时才自己找到了解决方案。
最终，我找到了解决方案，所以我将在下面为每个库发布解决方案，以帮助其他开发人员节省解决相同问题的时间。
要成功请求这样的网站，请尝试启用反向DNS（rDNS）。我将描述如何在requests和aiohttp库中执行此操作。
requests
要启用rDNS，您需要在代理URL的初始化中使用socks5h://...，而不是socks5://...。
requirements.txt
PySocks==1.7.1
requests==2.31.0
main.py
import requests
def main():
proxy = 'socks5://username:password@0.0.0.0:1111'
proxy = proxy.replace('socks5://', 'socks5h://')
# 或者只需
# proxy = 'socks5h://username:password@0.0.0.0:1111'
response = requests.get(url='https://www.example.com/', proxies={'http': proxy, 'https': proxy})
print(response.text)
if __name__ == '__main__':
main()
aiohttp
要启用rDNS，您需要在ProxyConnector的初始化期间传递rdns=True参数。
requirements.txt
aiohttp==3.8.4
aiohttp-socks==0.8.0
PySocks==1.7.1
main.py
import asyncio
import aiohttp
from aiohttp_socks import ProxyConnector
async def main():
proxy = 'socks5://username:password@0.0.0.0:1111'
connector = ProxyConnector.from_url(url=proxy, rdns=True)
async with aiohttp.ClientSession(connector=connector) as session:
async with session.get(url='https://www.example.com/') as response:
print(await response.text())
if __name__ == '__main__':
loop = asyncio.get_event_loop()
loop.run_until_complete(main())

I found the solution for the requests library in a couple minutes. But I didn't find a solution for aiohttp, so it took me several hours to find a solution on my own.
I finally found a solution, so I'm going to publish solutions for each of the libraries below to help other developers save time in solving the same problem.
To make a successful request to such a site try to enable reverse DNS (rDNS). I will describe how to do it for requests and aiohttp libraries.
requests
To enable rDNS, you need to use socks5h://... instead of socks5://... in a proxy URL.
requirements.txt
PySocks==1.7.1
requests==2.31.0
main.py
import requests
def main():
proxy = 'socks5://username:password@0.0.0.0:1111'
proxy = proxy.replace('socks5://', 'socks5h://')
# or just
# proxy = 'socks5h://username:password@0.0.0.0:1111'
response = requests.get(url='https://www.example.com/', proxies={'http': proxy, 'https': proxy})
print(response.text)
if __name__ == '__main__':
main()
aiohttp
To enable rDNS, you need to pass the rdns=True parameter during initialization of the ProxyConnector.
requirements.txt
aiohttp==3.8.4
aiohttp-socks==0.8.0
PySocks==1.7.1
main.py
import asyncio
import aiohttp
from aiohttp_socks import ProxyConnector
async def main():
proxy = 'socks5://username:password@0.0.0.0:1111'
connector = ProxyConnector.from_url(url=proxy, rdns=True)
async with aiohttp.ClientSession(connector=connector) as session:
async with session.get(url='https://www.example.com/') as response:
print(await response.text())
if __name__ == '__main__':
loop = asyncio.get_event_loop()
loop.run_until_complete(main())
