web3.js 查询指定区块

要查询指定区块，可以使用web3.eth.getBlock()函数，可以指定区块的序号或哈希值。

示例

app.js

const Web3 = require('web3')
const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_API_KEY') // YOUR_INFURA_API_KEY替换为你自己的key// 查询指定哈希值的区块
web3.eth.getBlock('0x25d9f9dd736ebaac3c99cb0edb5df22745c354d208c6e2b5b43f426f754adfbe').then(console.log)// 查询指定序号区块
web3.eth.getBlock(0).then(console.log)

运行app.js：

$ node app
