以太坊開發(fā)(二十七)在私鏈中使用JSON RPC API進(jìn)行以太幣/代幣轉(zhuǎn)賬

1. 前言

前面我們使用過(guò)web3.js進(jìn)行過(guò)以太幣/代幣轉(zhuǎn)賬，這次我們使用以太坊提供的JSON RPC API進(jìn)行以太幣/代幣轉(zhuǎn)賬。

官方文檔：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的時(shí)候，我們使用的是第三方節(jié)點(diǎn)，不需要自己建立節(jié)點(diǎn)和同步所有區(qū)塊(以太坊開發(fā)(二十三)使用Web3.js查詢以太幣和代幣余額以及轉(zhuǎn)賬)。

但如果是在主網(wǎng)使用JSON RPC API，需要建立自己的節(jié)點(diǎn)并同步所有主網(wǎng)區(qū)塊。原因是自己的節(jié)點(diǎn)可以使用錢包服務(wù)，第三方節(jié)點(diǎn)沒有提供錢包服務(wù)，就算有，也不敢輕易把私鑰傳過(guò)去吧。

這里為了測(cè)試，我們建立一個(gè)私鏈并啟動(dòng)一個(gè)節(jié)點(diǎn)。關(guān)于建立私鏈和啟動(dòng)節(jié)點(diǎn)，可以查看這篇文章以太坊開發(fā)(三)使用 Go-Ethereum 1.8.1搭建以太坊私有鏈。

2. 啟動(dòng)節(jié)點(diǎn)

這里啟動(dòng)節(jié)點(diǎn)和之前不太一樣，主要是需要為節(jié)點(diǎn)開啟RPC通道。

對(duì)比一下區(qū)別：

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
參數(shù)名稱 參數(shù)描述
datadir 設(shè)置當(dāng)前區(qū)塊鏈網(wǎng)絡(luò)數(shù)據(jù)存放的位置
nodiscover 私有鏈地址，不會(huì)被網(wǎng)上看到
console 啟動(dòng)命令行模式，可以在Geth中執(zhí)行命令
identity 區(qū)塊鏈的標(biāo)示，用于標(biāo)示目前網(wǎng)絡(luò)的名字
rpc 開啟rpc通道
rpcapi 要開放哪些rpc api
rpccorsdomain 允許能連接到你的節(jié)點(diǎn)執(zhí)行rpc api的url，使用逗號(hào)分隔。*表示任何url都可以連接
rpcaddr HTTP-RPC服務(wù)器接口地址，默認(rèn)為localhost
rpcport HTTP-RPC服務(wù)器端口地址，默認(rèn)為8545
networkid 網(wǎng)絡(luò)標(biāo)識(shí)，私有鏈取一個(gè)大于4的隨意的值

3. 一些主要的RPC API

可以使用PostMan開啟本地節(jié)點(diǎn)后使用Post調(diào)用

注意Content-Type設(shè)置為application/json

3.1 eth_accounts 獲取本地所有賬號(hào)地址

post

4. 相關(guān)工具

參數(shù)及返回值多數(shù)為十六進(jìn)制的值，可以使用進(jìn)制轉(zhuǎn)換工具快速轉(zhuǎn)換為十進(jìn)制的值查看進(jìn)制轉(zhuǎn)換。

如果代幣的小數(shù)位與以太幣一樣，都是18個(gè)0，可以使用Ethereum unit converter快速轉(zhuǎn)換。
