问从浏览器索引的数据库获取数据，然后调用api。

import { initDB, useIndexedDB } from "react-indexed-db";
initDB(DBConfig);

const db = useIndexedDB("reads");

    useEffect(() => {
        db.getByIndex("hash", props.match.params.id).then((data) => {
          setToken(data.token);
        });
        handleTextColorSelection(backgroundColor);
        axios
          .post(`${process.env.REACT_APP_API_URL}khatma/read`, {
            khatma: props.match.params.id,
            part: props.match.params.part,
            section: props.match.params.section,
            token: token,
          })
          .then((res) => {
        
            if (res.data.token) {
              db.add({
                hash: props.match.params.id,
                token: res.data.token,
              }).then(
                (event) => {},
                (error) => {
                  console.log(error);
                }
              );
            }
    })
