我需要断开一个传入的WebSocket连接，以防用户已经与服务器有一个实时连接，为此我在Starlette文档中建议调用websocket.close()。但是，当我调用以下代码时:
await websocket.close(code=1000, reason='Connection refused as session already exists for user')
服务器崩溃，并显示以下堆栈跟踪信息:unexpected keyword argument 'reason':

我需要让客户端知道由于特定原因连接被拒绝。请告诉我哪里做错了。
感谢您的宝贵时间。
我正在运行一个旧版本的FastAPI，其close()不支持"reason"论点。升级FastAPI到最新版本解决了"原因"问题;
可能对旁观者有类似的问题。
如果你想表达你想发送的原因数据，你可能会被控制帧的规范约束所抓住。
