根因分析

服务器返回了超过 max_redirects（默认 10）次重定向响应，通常由重定向循环或 cookie/认证配置错误引起。

English

The server returned more than max_redirects (default 10) redirect responses, often due to a redirect loop or cookie/auth misconfiguration.

解决方案

  1. 90% 成功率 
    Inspect the redirect chain with curl:

curl -sIL https://example.com/loop | grep -i '^location'
  2. 85% 成功率 
    Handle redirects manually to detect the loop:

async with session.get(url, allow_redirects=False) as r:
    while r.status in (301, 302, 303, 307, 308):
        url = r.headers['Location']
        r = await session.get(url, allow_redirects=False)
  3. 82% 成功率 
    Ensure cookies are sent (some redirect loops happen because auth cookie is missing):

session.cookie_jar.update_cookies({'session': token})

无效尝试

常见但无效的做法:

  1. 70% 失败

    If it's a true loop, it will still hit 100 and fail.

  2. 50% 失败

    You now receive 3xx responses directly and must handle Location yourself.

  3. 90% 失败

    Unrelated to redirect count.
