1. 前言
前面我们使用过web3.js
进行过以太币/代币转账,这次我们使用以太坊提供的JSON RPC API
进行以太币/代币转账。
官方文档:https://ethereum.gitbooks.io/frontier-guide/content/rpc.html
中文版:http://cw.hubwiz.com/card/c/ethereum-json-rpc-api/
之前使用web3.js
的时候,我们使用的是第三方节点,不需要自己建立节点和同步所有区块(以太坊开发(二十三)使用Web3.js查询以太币和代币余额以及转账)。
但如果是在主网使用JSON RPC API
,需要建立自己的节点并同步所有主网区块。原因是自己的节点可以使用钱包服务,第三方节点没有提供钱包服务,就算有,也不敢轻易把私钥传过去吧。
这里为了测试,我们建立一个私链并启动一个节点。关于建立私链和启动节点,可以查看这篇文章以太坊开发(三)使用 Go-Ethereum 1.8.1搭建以太坊私有链。
2. 启动节点
这里启动节点和之前不太一样,主要是需要为节点开启RPC
通道。
对比一下区别:
geth --datadir "./chain" --nodiscover console
geth --identity "rpc etherum" --datadir "./chain" --nodiscover --rpc --rpcapi "web3,eth,personal,miner" --rpccorsdomain "*" --rpcaddr 0.0.0.0 --rpcport 8545 --networkid 666 console
参数名称 | 参数描述 |
---|---|
datadir | 设置当前区块链网络数据存放的位置 |
nodiscover | 私有链地址,不会被网上看到 |
console | 启动命令行模式,可以在Geth中执行命令 |
identity | 区块链的标示,用于标示目前网络的名字 |
rpc | 开启rpc通道 |
rpcapi | 要开放哪些rpc api |
rpccorsdomain | 允许能连接到你的节点执行rpc api的url,使用逗号分隔。*表示任何url都可以连接 |
rpcaddr | HTTP-RPC服务器接口地址,默认为localhost |
rpcport | HTTP-RPC服务器端口地址,默认为8545 |
networkid | 网络标识,私有链取一个大于4的随意的值 |
3. 一些主要的RPC API
可以使用PostMan
开启本地节点后使用Post
调用
注意Content-Type
设置为application/json

4. 相关工具
参数及返回值多数为十六进制的值,可以使用进制转换工具快速转换为十进制的值查看进制转换。
如果代币的小数位与以太币一样,都是18个0,可以使用Ethereum unit converter快速转换。
5. 以太币转账

-
nonce
交易顺序十六进制。由eth_getTransactionCount
获取 -

转账方地址 -
to
接收方地址 -
gas
燃料十六进制。由eth_estimateGas
获取 -
gasPrice
燃料单价十六进制。由eth_gasPrice
获取 -
value
以太币数量十六进制
首先,保证转账方有足够的以太币支付要转账的以太币以及手续费
调用
personal_unlockAccount
解锁转账方账户调用上面的方法转账,获取到交易hash
在私链上,调用
miner_start
开启挖矿调用
eth_getTransactionByHash
及eth_getTransactionReceipt
查询是否交易打包入区块并得到确认调用
eth_getBalance
查询是否到账

data
附加的消息。这里由合约中transfer
方法,方法参数一(接收方地址),方法参数二(代币数量)的十六进制组成
首先需要将
ERC20
标准的代币合约部署在私链上。部署方法见以太坊开发(五)使用 Browser-solidity 在 Go-Ethereum1.8.1 上进行简单的智能合约部署保证转账方有足够的以太币支付手续费,有足够的代币转账
调用
personal_unlockAccount
解锁转账方账户调用上面的方法进行代币转账。
data
的拼接方法见以太坊开发(二十三)使用Web3.js查询以太币和代币余额以及转账在私链上,调用
miner_start
开启挖矿调用
eth_getTransactionByHash
及eth_getTransactionReceipt
查询是否交易打包入区块并得到确认调用
token_balanceOf
查询是否到账
