我正在尝试创建一个工作池,其中一个函数获取网站上的某些数据。但我似乎无法从获取中得到任何东西。

还有另一种获取方式吗?还是我做错了什么?

这是我的代码:

运行脚本.js

const workerpool = require('workerpool');
    const pool = workerpool.pool(__dirname + '/myWorker.js');
    pool.proxy()
        .then(function (worker) {
            worker.asyncFetch().then(r => console.log(r));
        })
        .catch(function (err) {
            console.error(err);
        })
        .then(function () {
            pool.terminate(); // terminate all workers when done
        });

myWorker.js

const workerpool = require('workerpool');

function asyncFetch () {
    const fetch = require('node-fetch');
    fetch('https://jsonplaceholder.typicode.com/todos/1')
        .then(response => response.json())
        .then(data => {
            console.log('the data');
            console.log(data)
        });
    return fetch('https://jsonplaceholder.typicode.com/todos/1');
}

// an async function returning a promise
function asyncMultiply (a, b) {
    return new Promise(function (resolve, reject) {
        setTimeout(function () {
            resolve(a * b);
        }, 1000);
    });
}

// create a worker and register public functions
workerpool.worker({
    asyncFetch: asyncFetch,
    asyncMultiply: asyncMultiply
});
