Reactjs useEffect 仅在跟随链接后有效，不适用于直接链接

我已经为我的报纸实现了无限滚动挂钩

  const [posts, setPosts] = useState([]);
  const [currentOffset, setCurrentOffset] = useState(0);

  const [isLoading, setLoading] = useState(true);
  const [isFetching, setIsFetching] = useState(false);

  let loadThreePosts = () => {
    axios.get(`/news?limit=3&offset=${currentOffset}`).then(({ data }) => {
      let threePosts = [];
      console.log(data);
      data.data.forEach((p) => threePosts.push(p));
      setPosts((posts) => [...posts, ...threePosts]);
      setLoading(false);
    });
    setCurrentOffset(currentOffset + 3);
  };

  useEffect(() => {
    window.addEventListener("scroll", handleScroll);
    return () => window.removeEventListener("scroll", handleScroll);
  }, []);

  useEffect(() => {
    if (!isFetching) return;
    fetchMorePosts();
  }, [isFetching]);

  function handleScroll() {
    if (
      window.innerHeight + document.documentElement.scrollTop !==
        document.documentElement.offsetHeight ||
      isFetching
    )
      return;
    setIsFetching(true);
  }

  function fetchMorePosts() {
    setTimeout(() => {
      loadThreePosts();
      setIsFetching(false);
    }, 2000);
  }

因此，如果我go 报纸上，在我的网站上投放链接，它会根据我的需要获取帖子， 但如果我将新闻链接粘贴到浏览器地址栏中，它不会获取任何内容
