useState 不在 axios promise 中执行

Question

这是 React 组件的一部分

  const listId = props.listId;
  const [list, setList] = useState({});
  useEffect(() => {
    let isMounted = true;
    axios.get(`http://localhost:9000/lists/${listId}`).then((res) => {
      if (isMounted) {
        setList({ ...res.data });
      }
    });
    return () => {
      isMounted = false;
    };
  });

由于某种原因，setList 没有执行
