Web3js教程

web3.js 查询区块中的交易

要查询某个区块中的指定交易信息,可以使用 web3.eth.getTransactionFromBlock(txHash, blockNum)函数。
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
// 查询某个区块中的指定交易信息
const hash = '0x66b3fd79a49dafe44507763e9b6739aa0810de2c15590ac22b5e2f0a3f502073'
web3.eth.getTransactionFromBlock(hash, 2).then(console.log)
运行app.js:
$ node app
输出
{ blockHash:
   '0x66b3fd79a49dafe44507763e9b6739aa0810de2c15590ac22b5e2f0a3f502073',
