在执行Action（Redux）之前调用工作程序

Question

用户登录并存储在索引数据库中后，尝试调用api来获取一些数据。但是在登录之前，即一旦应用程序启动，工作代码便会被调用，从而完成工作。

app-worker.js

import Api from "./api/index";
import { openDb, addToStore, closeDb } from "./indexedDB";

self.onmessage = (oEvent) => {
    Api().get("person").then((results) => {
        openDb();
        addToStore({
            storeName: "persons",
            data: results,
        });
        closeDb();
    });
};

workerfile.js

import Worker from "./app-worker.js";

let workerObj = null;

export function startWorker() {
    workerObj = new Worker();
    workerObj.postMessage();
}

export function stopWorker() {
    workerObj.terminate();
}

actionfile.js

import { startWorker } from "../workerfile";

export const login = (user, history) => async (dispatch) => {
    dispatch({ type: LOGIN_USER });
    Api().post("login", user)
        .then((result) => {
            dispatch({
                type: LOGIN_USER_SUCCESS,
                payload: result.user
            });
            history.push("/home");
            startWorker();
        })
        .catch((err) => {
            dispatch({
                type: LOGIN_USER_FAILURE,
            });
        });
};

要求是用户登录->让工作程序运行，直到从api获取数据并将其存储在数据库中为止->停止工作程序
