解决方案

  1. 90% 成功率 Use aiohttp.BasicAuth for proxy authentication

async with session.get(url, proxy='http://proxy.example.com:8080', proxy_auth=proxy_auth) as resp:

无效尝试

常见但无效的做法:

  1. Providing empty username and password 60% 失败

    Most proxies reject empty credentials, causing the same error.

  2. Using HTTP Basic Auth headers manually without proper encoding 50% 失败

    Incorrect encoding or missing headers may still result in 407.
