# swtc-proxy 文档

# jingtum-api 官方文档 (opens new window)

# @swtc/proxy 说明

# 对 jingtum-api 作出包装，消除不安全操作并且提供类似@swtc/lib 的接口支持 jingtum-api 缺失的操作

# 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

# 同时支持jingtum-api 和 swtc-proxy

# 多重签名测试链上没有支持

# 目前文档输出为 swtc-proxy, 老版本 (opens new window)以jingtum-api输出为例

# 操作以swtc-proxy支持为主，部分功能在jingtum-api不支持

# 后端选择/准备

# swtc-proxy, 推荐

# 公链 http://swtcproxy.swtclib.ca:5080

# 测试 http://swtcproxy.swtclib.ca:5081

# jingtum-api, 本身允许不安全操作，注意

# 公链 https://api.jingtum.com

# 测试链 https://tapi.jingtum.com

# 1 安装

安装库

npm install --save @swtc/api

# 2 项目说明

# swtc-api 库操作jingtum-api提供的 restapi, 但是实现了本地签名，避免密钥传输到网络上

# swtc-api 库操作swtc-proxy提供的 restapi

# swtc-api 提供比jingtum-api 和 swtc-proxy 更多的操作, 有完整的接口

# 3 创建钱包

# 首先引入 swtc-api 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 japi = require("@swtc/api")
var Wallet = japi.Remote.Wallet
//方式一
var w1 = Wallet.generate()

console.log(w1)
//方式二
var w2 = Wallet.fromSecret("ssiUDhUpUZ5JDPWZ9Twt27Ckq6k4C")
console.log(w2)

# 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 jingtum-api 的 restapi 交互的类，它包装所有 jingtum-api 提供的方法, 还提供额外的类似@swtc/lib 的接口

# 11.3 废除帐号的主密钥

# 本功能为禁止某账号做交易而设定，且只有该账号设置了签名列表才可以废除 masterkey 成功。首先通过 buildAccountSetTx 方法返回一个 Transaction 对象，最后通过 submitPromise 方法提交到底层

# 11.3.1 创建废除密钥交易

# 方法:remote.buildAccountSetTx({})

# 参数

参数	类型	说明
account	String	被废除或激活 masterkey 的账号
type	String	类型，这里固定为 property
set_flag	Integer	4 表示废除

# 返回:Transaction 对象

# 11.3.2 废除

# 方法:tx.submitPromise(secret);

# 参数: 密钥

参数	类型	说明
secret	String	钱包私钥

# 返回: Promise

# SWTC-API

# 0 后端支持

# swtc-proxy 文档

# jingtum-api 官方文档 (opens new window)

# @swtc/proxy 说明

# 对 jingtum-api 作出包装， 消除不安全操作 并且提供类似@swtc/lib 的接口支持 jingtum-api 缺失的操作

# 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

# 同时支持jingtum-api 和 swtc-proxy

# 多重签名测试链上没有支持

# 目前文档输出为 swtc-proxy, 老版本 (opens new window)以jingtum-api输出为例

# 操作以swtc-proxy支持为主， 部分功能在jingtum-api不支持

# 后端选择/准备

# swtc-proxy, 推荐

# 公链 http://swtcproxy.swtclib.ca:5080

# 测试 http://swtcproxy.swtclib.ca:5081

# jingtum-api, 本身允许不安全操作，注意

# 公链 https://api.jingtum.com

# 测试链 https://tapi.jingtum.com

# 1 安装

# 2 项目说明

# swtc-api 库操作jingtum-api提供的 restapi, 但是实现了本地签名， 避免密钥传输到网络上

# swtc-api 库操作swtc-proxy提供的 restapi

# swtc-api 提供比jingtum-api 和 swtc-proxy 更多的操作, 有完整的接口

# 3 创建钱包

# 首先引入 swtc-api 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:

# 返回的结果信息:

# 输出

# 4 REMOTE 类

# Remote 是跟 jingtum-api 的 restapi 交互的类，它包装所有 jingtum-api 提供的方法, 还提供额外的类似@swtc/lib 的接口

# swtc-api REMOTE 独享

# 4.1 创建 Remote 对象

# 方法:new Remote(options);

# 参数:

# 例子

# 4.2 获得账号余额

# 方法:remote.getAccountBalances(address);

# 参数:

# 可选参数:

# 返回: Promise - json

# 例子

# 返回结果

# 返回结果说明

# 4.3 获得账号支付信息

# 方法:remote.getAccountPayment(address, hash);

# 参数:

# 返回: Promise - json

# 例子

# 返回结果

# 返回结果说明

# 4.4 获得账号支付记录

# 方法:remote.getAccountPayments(address);

# 参数:

# 返回: Promise - json

# 返回结果说明

# 4.5 获得账号挂单信息

# 方法:remote.getAccountOrder(address, hash);

# 参数:

# 返回: Promise - json

# 例子

# 返回结果

# 4.6 获得账号挂单列表

# 方法:remote.getAccountOrders(address);

# 参数:

# 返回: Promise - json

# 例子

# 返回结果

# 4.7 获得账号事务信息

# 方法:remote.getAccountTransaction(address, hash);

# 参数:

# 返回: Promise - json

# 例子

# 返回结果

# 4.8 获得账号交易记录

# 方法:remote.getAccountTransactions(address);

# 对 jingtum-api 作出包装，消除不安全操作并且提供类似@swtc/lib 的接口支持 jingtum-api 缺失的操作

# 同时支持`jingtum-api` 和 `swtc-proxy`

# 目前文档输出为 `swtc-proxy`, 老版本 (opens new window)以`jingtum-api`输出为例

# 操作以`swtc-proxy`支持为主，部分功能在`jingtum-api`不支持

# swtc-api 库操作`jingtum-api`提供的 restapi, 但是实现了本地签名，避免密钥传输到网络上

# swtc-api 库操作`swtc-proxy`提供的 restapi

# swtc-api 提供比`jingtum-api` 和 `swtc-proxy` 更多的操作, 有完整的接口
