Hyperledger Burrow 使用web3.js接口

环境

os:centos7.6
nodejs:v8.11.4

安装web3.js

npm install ethereum/web3.js --save

web3.js接口测试

1. 进入node控制台

node

2. 定义web3变量

注意>号不是命令的一部分

//使用web3模块
> var Web3 = require('web3')
//创建web3实例（假设burrow rpc监听端口为26860）
> var web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:26860"));

3. 测试

> web3.eth.blockNumber
133
> web3.eth.getBlock(133)
