解决方案

  1. 85% 成功率 Verify proxy settings and use proxy authentication if needed 
    proxy_auth = aiohttp.BasicAuth('user', 'pass')
async with aiohttp.ClientSession() as session:
    async with session.get(url, proxy='http://proxy.example.com:8080', proxy_auth=proxy_auth) as resp:
  2. 80% 成功率 Use environment variables for proxy configuration 
    import os
os.environ['HTTP_PROXY'] = 'http://proxy.example.com:8080'
os.environ['HTTPS_PROXY'] = 'http://proxy.example.com:8080'

无效尝试

常见但无效的做法:

  1. Disabling proxy usage entirely 40% 失败

    This may bypass corporate network policies or cause direct access failures.

  2. Using a different proxy without authentication 50% 失败

    The new proxy may also be unreachable or require authentication.
