这是我跟着教学视频写的
require("dotenv").config();
const Web3 = require('web3');
const web3 = new Web3(
new Web3.providers.WebsocketProvider(process.env.INFURA_URL)
);

web3.eth.subscribe('newBlockHeaders')
.on('data', async block => {
console.log(New block received. Block # ${block.number});
})
.on('error', error => {
console.log(error);
});
