我得到的第一个响应是一个空列表

Question

I'm getting data from API like this:

const [software, setSoftware] = useState([]);

const id = match.params.id;

useEffect(() => {
  fetch(`http://127.0.0.1:8000/api/software/${id}/`)
      .then(response => response.json())
      .then(data => {
        setSoftware(data)
      })
}, [id]);

First response is an empty list, but the next response is my list from API. I tried to use useEffect because setSoftwares is asynchronous, but it didn't help. So how can I get only my list?

I think you are sending incorrect id for the first time, try to console.log(id) it and check-in the console if id is valid or not.
