根因分析

WebSocket 路由在 accept() 之前抛出异常，或认证依赖返回了非 101 响应，导致握手被拒绝。

English

The WebSocket route raised before accept(), or an auth dependency returned a non-101 response, causing the handshake to be rejected.

generic

解决方案

  1. 88% 成功率 
    Accept first then validate: await websocket.accept(); if not token_ok: await websocket.close(code=1008)
  2. 90% 成功率 
    Pass token as query param: /ws?token=... and verify before accept

无效尝试

常见但无效的做法:

  1. 85% 失败

    Server keeps rejecting; retries never succeed.

  2. 60% 失败

    Security regression; not acceptable in production.
