问题: 飞书 WebSocket 接收消息 API 返回 404 错误。测试端点: wss://open.feishu.cn/open-apis/bot/v3/ws, /bot/v2/ws, /im/v1/ws, /im/v2/ws, /webhook/v1/ws。所有端点均返回 404。修复: 消息发送功能正常 (通过 HTTP API with receive_id_type=chat_id), 但接收消息必须使用 HTTP Webhook 回调方式。验证: 2026-05-19 测试确认。
结论: 不要继续轮换 WebSocket 路径；在飞书开发者后台配置可访问的 HTTP Webhook URL，并校验事件订阅验证请求与签名。
