以太坊开发(二十七)在私链中使用JSON RPC API进行以太

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

3.1 `eth_accounts` 获取本地所有账号地址

post
http://0.0.0.0:8545

method:
eth_accounts

params:
{"jsonrpc":"2.0","method":"eth_accounts","params":[],"id":666}

returns:
{
    "jsonrpc": "2.0",
    "id": 666,
    "result": [
        "0xb6cd75af6594f46374378cf3a7d9cbfc06485994",
        "0x696d69b81c6bdf6d46ddb66ee2175df7f9de7c46",
        "0x04a2dfca5b31be1a5d5a56b6a242e7786b24859d",
        "0x460c6c45f500c63209ae99de0cd1b4b8ba90a680"
    ]
}

result：账号地址列表

3.2 `eth_blockNumber` 获取当前最新区块号

post
http://0.0.0.0:8545

method:
eth_blockNumber

params:
{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":666}

returns:
{
    "jsonrpc": "2.0",
    "id": 666,
    "result": "0x84"
}

result：区块号十六进制

3.3 `eth_getBalance` 获取指定地址的以太币余额

{"jsonrpc":"2.0","method":"eth_getBalance","params":["0x696d69b81c6bdf6d46ddb66ee2175df7f9de7c46", "latest"],"id":666}

0x696d69b81c6bdf6d46ddb66ee2175df7f9de7c46：要查询的地址

HEX String - 指定区块号的十六进制
String "earliest" - 表示最初或创世区块号
String "latest" - 表示最新挖出的区块号
String "pending" - 表示pending状态的交易

returns:
{
    "jsonrpc": "2.0",
    "id": 666,
    "result": "0x1042e5fe02ea790864"
}

result：余额十六进制

3.4 `eth_getBlockTransactionCountByNumber` 获取指定区块的交易数

post
http://0.0.0.0:8545

method:
eth_getBlockTransactionCountByNumber

params:
{"jsonrpc":"2.0","method":"eth_getBlockTransactionCountByNumber","params":["0xa"],"id":666}

0xa：要查询的区块号十六进制

returns:
{
    "jsonrpc": "2.0",
    "id": 666,
    "result": "0x0"
}

result：交易数十六进制

3.5 `eth_getBlockByNumber` 获取指定高度的区块详情

post
http://0.0.0.0:8545

method:
eth_getBlockByNumber

params:
{"jsonrpc":"2.0","method":"eth_getBlockByNumber","params":["0x107", true],"id":666}

0x107：要查询的区块号十六进制
true：返回区块中所有交易的详情，false只返回交易的hash

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。

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

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
