Apollo钩子useSubscription无限地订阅/取消订阅

Question

我的项目使用apollo useSubscription钩子和gqlgen golang服务器。

问题：当订阅来自UI（来自站点）时，在服务器端，我看到无限地订阅/取消订阅

当我使用GraphQL Playground订阅时，一切都很好，我有1个订阅日志记录，许多收到发布，订阅完成后只有一个“通道关闭原因”。

const httpLink = new HttpLink({
  uri: REACT_APP_GRAPHQL_URL,
});

const wsLink = new WebSocketLink({
  uri: REACT_APP_GRAPHQL_SUBSCRIPTION_URL,
  options: {
    reconnect: true,
    connectionParams: {
      authToken: Cookies.get('token'),
    },
  },
});

const link = split(
  ({ query }) => {
    const definition = getMainDefinition(query);

    return (
      definition.kind === 'OperationDefinition' &&
      definition.operation === 'subscription'
    );
  },
  wsLink,
  httpLink,
);

const client = new ApolloClient({
  uri: REACT_APP_GRAPHQL_URL,
  // eslint-disable-next-line
  // @ts-ignore
  link,
  cache: new InMemoryCache(),
  credentials: 'include',
  clientState,
});

const UPDATE_BALANCE_SUBSCRIPTION = gql`
  subscription balanceUpdate {
    balanceUpdate {
      walletId
      amount
    }
  }
`;

export const useBalanceUpdateSubscription = () => {
  return useSubscription<balanceUpdate>(UPDATE_BALANCE_SUBSCRIPTION);
};

挂钩的配置是标准配置，如阿波罗官方文档中所述。因此，为什么我们在行为上有所不同，这有点令人困惑。你能帮我吗？
