Apollo 客户端延迟刷新

In Apollo Client v3React 实现，我使用钩子来使用订阅。当我从订阅接收数据时，我想重新获取查询，但前提是查询之前已执行过并且位于缓存中。有办法实现这一点吗？

我首先进行惰性查询，然后在收到订阅数据时手动检查缓存，然后尝试执行惰性查询并重新获取。它可以工作，但只是感觉很笨重......

export const useMyStuffLazyRefetch = () => {
    const [refetchNeeded, setRefetchNeeded] = useState<boolean>(false);
    const client = useApolloClient();
    const [getMyStuff, { data, refetch }] = useLazyQuery<IStuffData>(GET_MY_STUFF);

    useEffect(() => {
        if (refetchNeeded) {
            setRefetchNeeded(false);
            refetch();
        }
    }, [refetchNeeded]);

    const refetchIfNeeded = async () => {
        const stuffData = client.cache.readQuery<IStuffData>({ query: GET_MY_STUFF });
        if (!stuffData?.myStuff?.length) return;
        getMyStuff();
        setRefetchNeeded(true);
    }

    return {
        refetchIfNeeded: refetchIfNeeded
    };
}

useLazyQuery有一个名为called，这是一个布尔值，指示查询函数是否已被调用，

所以也许你可以尝试这个：

export const useMyStuffLazyRefetch = () => {
    const [refetchNeeded, setRefetchNeeded] = useState<boolean>(false);
    const client = useApolloClient();
    const [getMyStuff, { data, refetch, called }] = useLazyQuery<IStuffData>(GET_MY_STUFF);

    useEffect(() => {
        if (refetchNeeded) {
            setRefetchNeeded(false);

            if (called) {
              refetch();
            }
            else {
              getMyStuff()
            }
        }
    }, [refetchNeeded, called]);

    const refetchIfNeeded = async () => {
        const stuffData = client.cache.readQuery<IStuffData>({ query: GET_MY_STUFF });
        if (!stuffData?.myStuff?.length) return;
        getMyStuff();
        setRefetchNeeded(true);
    }

    return {
        refetchIfNeeded: refetchIfNeeded
    };
}
