Root Cause

Starlette 应用中的重定向配置导致无限循环

generic

中文

Starlette 应用中的重定向配置导致无限循环

Workarounds

  1. 90% success 检查并修复重定向逻辑 
    # 确保不重定向到自身
if request.url.path != '/target':
    return RedirectResponse('/target')
  2. 85% success 使用条件重定向避免循环 
    if not request.cookies.get('redirected'):
    response = RedirectResponse('/target')
    response.set_cookie('redirected', '1')
    return response

Dead Ends

Common approaches that don't work:

  1. 增加重定向次数限制但未修复逻辑 70% fail

    最终仍会失败，且用户体验差

  2. 删除所有重定向路由 60% fail

    可能破坏应用功能
