[zeromicro/go-zero]当我使用 websocket 时，出现错误：“写入响应失败，错误：http：连接已被劫持”

我的问题 在消息网关服务中，在建立 websocket 连接后，我发送了消息，发送者收到了响应，接收者也收到了消息。但第二次发送消息失败，出现错误：“httpx/responses.go:78”，“content”：“写入响应失败，错误：http：连接已被劫持”

重现 步骤以重现该行为（如果适用）：

1. 代码如下

   func ws() {
   var wsConfig wsconfig.Config
   conf.MustLoad(*wsConfigFile, &wsConfig)
   serveCtx := servectx.NewServiceContext(wsConfig)
   wsConfig.RestConf.Timeout = 0
   server := rest.MustNewServer(wsConfig.RestConf)
   defer server.Stop()
   
   handler.RegisterHandler(server, serveCtx)
   utils.PrintlnSuccess("Starting websocket server at")
   server.Start()
   }

   func RegisterHandler(server *rest.Server, serveCtx *servectx.ServiceContext) {
       logic.NewMsgGatewayLogic(context.Background(), serveCtx)
       server.AddRoutes([]rest.Route{
           {
               Method:  http.MethodGet,
               Path:    "/login",
               Handler: MsgGatewayHandler(serveCtx),
           },
       })
    }

   func MsgGatewayHandler(serveCtx *servectx.ServiceContext) http.HandlerFunc {
       return func(writer http.ResponseWriter, request *http.Request) {
           var req types.Request
           if err := httpx.Parse(request, &req); err != nil {
               httpx.Error(writer, err)
               return
           }
           ws := logic.NewMsgGatewayLogic(context.Background(), serveCtx)
                   // verify token
           resp, ok := ws.MsgGatewayVerify(&req)
           if ok {
               logx.Info("resp uid is", resp.Uid)
               err := ws.WsUpgrade(resp.Uid, writer, request, nil)
               if err != nil {
                   return
               }
               httpx.WriteJson(writer, http.StatusOK, resp)
           } else {
               http.Error(writer, http.StatusText(http.StatusUnauthorized), http.StatusUnauthorized)
           }
       }
   }

   2. 错误是

      2022/07/08 10:44:34 http: response.WriteHeader on hijacked connection from github.com/zeromicro/go-zero/rest/handler. 
      (*loggedResponseWriter).WriteHeader (loghandler.go:66)
