SWTCLIB

# SWTC-LIB

# 0. 接口说明

# 强制本地签名
# 合约测试只能在特定节点运行, solidity 支持到 0.5.4, 需要安装 swtc-tum3 / tum3-eth-abi, 没有达到可用阶段
# 集成生态节点 failover const remote = new Remote() ; remote.connectPromise().then(console.log).catch(console.error)
# 多重签名测试链上没有支持
# 应用实例

# 1 安装

  1. 安装 SWTC 公链库
npm install --save @swtc/lib

# 2 项目文件结构

# @swtc/lib 库基于 ws 协议跟底层交互，其中 ws 封装到 Server 类中，Server 类是一个内部类，不对 外开放;Server 类封装在 Remote 类中，Remote 类提供对外访问接口并可创建两类对象:Get 方 式请求的 Request 对象和 Post 方式请求的 Transaction 对象，这两类对象都通过 submit()或者 submitPromise()方法提交 数据到底层。

文件结构图如下 structure

# 3 创建钱包

# 首先引入@swtc/lib 库的 Wallet 对象，然后使用以下两种方法创建钱包
# 方法 1: Wallet.generate()
# 方法 2: Wallet.fromSecret(secret);
# 参数:
参数 类型 说明
secret String 井通钱包私钥
//创建Wallet对象
var jlib = require("@swtc/lib")
var Wallet = jlib.Wallet
//方式一
var w1 = Wallet.generate()

console.log(w1)
//方式二
var w2 = Wallet.fromSecret("ssiUDhUpUZ5JDPWZ9Twt27Ckq6k4C")
var w3 = Wallet.fromSecret("ssLX1xmdj51Gu4BemCKb1ZKhFTjec")
var w4 = Wallet.fromSecret("snaSEqR4cTU6stvgtQKjq9FNPet8m")
console.log(w2)
console.log(w3)
# 返回的结果信息:
参数 类型 说明
secret String 井通钱包私钥
address String 井通钱包地址
# 输出
> Wallet.generate()
{ secret: 'ssiUDhUpUZ5JDPWZ9Twt27Ckq6k4C',
  address: 'jpmKEm2sUevfpFjS7QHdT8Sx7ZGoEXTJAz' }

# 4 REMOTE 类

# Remote 是跟井通底层交互最主要的类，它可以组装交易发送到底层、订阅事件及从底层拉取数据。提供以下方法:
  • Remote(options)
  • connect(callback)
  • disconnect()
  • requestServerInfo()
  • requestLedgerClosed()
  • requestLedger(options)
  • requestTx(options)
  • requestAccountInfo(options)
  • requestAccountTums(options)
  • requestAccountRelations(options)
  • requestAccountOffers(options)
  • requestAccountTx(options)
  • requestOrderBook(options)
  • requestPathFind(options)
  • createAccountStub()
  • createOrderBookStub()
  • buildPaymentTx(options)
  • buildRelationTx(options)
  • buildAccountSetTx(options)
  • buildOfferCreateTx(options)
  • buildOfferCancelTx(options)
  • deployContractTx(options)
  • callContractTx(options)
# @swtc/lib REMOTE 独享
  • makeCurrency()
  • makeAmount()
  • remote.connectPromise()
  • req.submitPromise()
  • tx.signPromise()
  • tx.submitPromise()

# 4.1 创建 Remote 对象

# 方法:new Remote(options);
# 参数:
参数 类型 说明
server String 井通底层服务地址
issuer String 默认银关
solidity Boolean 启用 solidity 支持
# 例子
var jlib = require("@swtc/lib")
var Remote = jlib.Remote
var remote = new Remote({
  server: "ws://ts5.jingtum.com:5030",
  issuer: "jBciDE8Q3uJjf111VeiUNM775AMKHEbBLS"
})

# 4.2 创建连接

# 每个 Remote 对象都应该首先手动连接底层，然后才可以请求底层的数据。请求结果在回调函数 callback 中
# 方法: connect(callback)
# 参数: 回调函数 callback(err, result)
# 方法: connectPromise()
# 参数: 无
# 例子
var jlib = require("@swtc/lib")
var Remote = jlib.Remote
var remote = new Remote({
  server: "ws://ts5.jingtum.com:5030",
  issuer: "jBciDE8Q3uJjf111VeiUNM775AMKHEbBLS"
})
// remote.connect( (error, server_info) => {
// 	if (error) {
// 		console.log(error)
// 	} else {
// 		console.log(server_info)
// 		remote.disconnect()
// 	}
// })
remote
  .connectPromise()
  .then(server_info => {
    console.log(server_info)
    remote.disconnect()
  })
  .catch(console.error)

# 例子:
var jlib = require("@swtc/lib")
var Remote = jlib.Remote

# 5 REQUEST 类

# Request 类主管 GET 请求，包括获得服务器、账号、挂单、路径等信息。请求时不需要提供密 钥，且对所有用户公开。所有的请求是异步的，会提供一个回调函数。每个回调函数有两个参 数，一个是错误，另一个是结果。提供以下方法:
  • selectLedger(ledger)
  • submit(callback)
  • submitPromise()

# 5.1 指定账本

# 方法:selectLedger(ledger);
# 参数:
参数 类型 说明
ledger String 账本高度或者账号 hash
# 例子
var jlib = require("@swtc/lib")
var Remote = jlib.Remote
var remote = new Remote({
  server: "ws://ts5.jingtum.com:5030",
  issuer: "jBciDE8Q3uJjf111VeiUNM775AMKHEbBLS"
})
remote.connect(function (err, result) {
  if (err) {
    return console.log("err:", err)
  }
  var req = remote.requestAccountInfo({
    account: "jpmKEm2sUevfpFjS7QHdT8Sx7ZGoEXTJAz"
  })
  req.selectLedger("2846000")
  req.submitPromise().then(console.log).catch(console.error)
})

# 5.2 提交请求

# 方法:submit(callback);
# 参数:回调函数，包含两个参数:错误信息和结果信息
# 方法:submitPromise(secret, memo);
# 参数:
参数 类型 说明
secret String 井通钱包私钥
memo String 备注信息
# 返回: Promise
# 例子
var jlib = require("@swtc/lib")
var Remote = jlib.Remote
var remote = new Remote({
  server: "ws://ts5.jingtum.com:5030",

# 6 TRANSACTION 类

# Transaction 类主管 POST 请求，包括组装交易和交易参数。请求时需要提供密钥，且交易可以 进行本地签名和服务器签名。目前支持服务器签名，本地签名支持主要的交易，还有部分参数 不支持。所有的请求是异步的，会提供一个回调函数。每个回调函数有两个参数，一个是错误， 另一个是结果。提供以下方法:
  • getAccount()
  • getTransactionType()
  • setSecret(secret)
  • addMemo(memo)
  • setPath(key)
  • setSendMax(amount)
  • setTransferRate(rate)
  • setFlags(flags)
  • submit(callback)
# 额外
  • signPromise(secret, [memo, [sequence])]
  • submitPromise(secret, [memo, [sequence])]

# 6.1 获得交易账号

# 方法:getAccount();
# 参数:无
# 返回:账号
# 例子:
var jlib = require("@swtc/lib")
var Remote = jlib.Remote
var remote = new Remote({
  server: "ws://ts5.jingtum.com:5030",
  issuer: "jBciDE8Q3uJjf111VeiUNM775AMKHEbBLS"
})
var options = { account: "jpmKEm2sUevfpFjS7QHdT8Sx7ZGoEXTJAz", sequence: 4 }
var tx = remote.buildOfferCancelTx(options)
var account = tx.getAccount()
console.log(account)

# 6.2 获得交易类型

# 方法:getTransactionType();
# 参数:无
# 返回:交易类型
# 例子:
var jlib = require("@swtc/lib")
var Remote = jlib.Remote
var remote = new Remote({

# 12. ED25519 支持

# 12.0 EDDSA - ed25519

# 井通默认的签名算法是 ecdsa， 不过同时也支持 eddsa （ed25519）签名
# ed25519 签名的对象是数据本身， 而其他的(包括 ecdsa)签名对象是数据的哈希
# 自 wallet 以上，包括 serializer, transaction, lib, 公共方法对 ed25519 的支持是透明的
# ed25519 的处理发主要在 address-codec 和 keypair 上

# 12.1 生成钱包, 提供算法作为参数

const { Wallet } = require("@swtc/wallet")
const data = "1234567890abcdef" // hashed for ecdsa, raw for ed25519

let secret_ecdsa = Wallet.KeyPair.generateSeed()
// or Wallet.generate()
console.log(Wallet.fromSecret(secret_ecdsa))
let wallet_ecdsa = new Wallet(secret_ecdsa)
console.log(wallet_ecdsa)
let signed_ecdsa = wallet_ecdsa.signTx(data)
console.log(`signed_ecdsa = ${signed_ecdsa}`)
let verified_ecdsa = wallet_ecdsa.verifyTx(data, signed_ecdsa)
console.log(`verified_ecdsa = ${verified_ecdsa}`)

let secret_ed25519 = Wallet.KeyPair.generateSeed({ algorithm: "ed25519" })
// or Wallet.generate({algorithm: "ed25519"})
console.log(Wallet.fromSecret(secret_ed25519))
let wallet_ed25519 = new Wallet(secret_ed25519)
console.log(wallet_ed25519)
let signed_ed25519 = wallet_ed25519.signTx(data)
console.log(`signed_ed25519 = ${signed_ed25519}`)
let verified_ed25519 = wallet_ed25519.verifyTx(data, signed_ed25519)
console.log(`verified_ed25519 = ${verified_ed25519}`)
