Java sdk 使用说明

Version 1.0.0

English / 中文

ONT中有两种资产：原生资产和合约资产。原生资产如ont和ong。交易所对接时，主要处理这两种类型资产的充值、提现等操作。

本文大纲如下：

Java sdk 使用说明

1. 公私钥和地址

账户是基于公私钥创建的，地址是公钥转换而来。

1.1 公私钥存储

公私钥存储可以存储在数据库中，也可以根据钱包规范存储在文件中。

1.1.1 自己存储：

自己存储，是指账户信息保存在用户数据库或其他地方，而不存储在遵循钱包规范的文件中。

随机创建账号：

com.github.ontio.account.Account acct = new com.github.ontio.account.Account(ontSdk.defaultSignScheme);
acct.serializePrivateKey();//私钥
acct.serializePublicKey();//公钥
acct.getAddressU160().toBase58();//base58地址

根据私钥创建账号

com.github.ontio.account.Account acct0 = new com.github.ontio.account.Account(Helper.hexToBytes(privatekey0), ontSdk.defaultSignScheme);
com.github.ontio.account.Account acct1 = new com.github.ontio.account.Account(Helper.hexToBytes(privatekey1), ontSdk.defaultSignScheme);
com.github.ontio.account.Account acct2 = new com.github.ontio.account.Account(Helper.hexToBytes(privatekey2), ontSdk.defaultSignScheme);

1.1.2 按钱包规范存储：

账户和身份信息保持在遵循钱包规范的文件中。例子

在钱包中批量创建账号:

一个创建多个账号的方法。

ontSdk.getWalletMgr().createAccounts(10, "passwordtest");
ontSdk.getWalletMgr().writeWallet();

随机创建:
AccountInfo info0 = ontSdk.getWalletMgr().createAccountInfo("passwordtest");

通过私钥创建:
AccountInfo info = ontSdk.getWalletMgr().createAccountInfoFromPriKey("passwordtest","e467a2a9c9f56b012c71cf2270df42843a9d7ff181934068b4a62bcdd570e8be");

获取账号
com.github.ontio.account.Account acct0 = ontSdk.getWalletMgr().getAccount(info.addressBase58,"passwordtest",salt);

1.2 地址

包括单签地址和多签地址,生成方式与NEO地址相同。

签地址是由一个公钥转换而来，多签地址是由多个公钥转换而来。

单签地址生成：
String privatekey0 = "c19f16785b8f3543bbaf5e1dbb5d398dfa6c85aaad54fc9d71203ce83e505c07";
String privatekey1 = "49855b16636e70f100cc5f4f42bc20a6535d7414fb8845e7310f8dd065a97221";
String privatekey2 = "1094e90dd7c4fdfd849c14798d725ac351ae0d924b29a279a9ffa77d5737bd96";

//生成账号，获取地址
com.github.ontio.account.Account acct0 = new com.github.ontio.account.Account(Helper.hexToBytes(privatekey0), ontSdk.defaultSignScheme);
Address sender = acct0.getAddressU160();

//base58地址解码
sender = Address.decodeBase58("AVcv8YBABi9m6vH7faq3t8jWNamDXYytU2")；

多签地址生成：
Address recvAddr = Address.addressFromMultiPubKeys(2, acct1.serializePublicKey(), acct2.serializePublicKey());

方法名	参数	参数描述
addressFromMultiPubkeys	int m,byte[]... pubkeys	最小验签个数(<=公钥个数)，公钥

2. 原生资产转账

参考例子：例子

2.1 初始化

转账之前需要创建SDK实例，配置节点IP。

String ip = "http://polaris1.ont.io";
String rpcUrl = ip + ":" + "20336";
OntSdk ontSdk = OntSdk.getInstance();
ontSdk.setRpc(rpcUrl);
ontSdk.setDefaultConnect(wm.getRpc());

或使用restful：
String restUrl = ip + ":" + "20334";
ontSdk.setRestful(restUrl);
ontSdk.setDefaultConnect(wm.getRestful());

也可以选择websocket：
String wsUrl = ip + ":" + "20335";
ontSdk.setWesocket(wsUrl, lock);
ontSdk.setDefaultConnect(wm.getWebSocket());

2.2 查询

当发完交易之后可能需要查询交易是否已经落账，还可能需要查询账户余额。

查询ont，ong余额

ontSdk.getConnect().getBalance("AVcv8YBABi9m6vH7faq3t8jWNamDXYytU2");
ontSdk.nativevm().ont().queryBalanceOf("AVcv8YBABi9m6vH7faq3t8jWNamDXYytU2")
ontSdk.nativevm().ong().queryBalanceOf("AVcv8YBABi9m6vH7faq3t8jWNamDXYytU2")

查ont信息：
System.out.println(ontSdk.nativevm().ont().queryName());
System.out.println(ontSdk.nativevm().ont().querySymbol());
System.out.println(ontSdk.nativevm().ont().queryDecimals());
System.out.println(ontSdk.nativevm().ont().queryTotalSupply());

查ong信息：
System.out.println(ontSdk.nativevm().ong().queryName());
System.out.println(ontSdk.nativevm().ong().querySymbol());
System.out.println(ontSdk.nativevm().ong().queryDecimals());
System.out.println(ontSdk.nativevm().ong().queryTotalSupply());

查询交易是否在交易池中

通过接口查询交易是否在交易池中

ontSdk.getConnect().getMemPoolTxState("d441a967315989116bf0afad498e4016f542c1e7f8605da943f07633996c24cc")


response 交易池存在此交易:

{
    "Action": "getmempooltxstate",
    "Desc": "SUCCESS",
    "Error": 0,
    "Result": {
        "State":[
            {
              "Type":1,
              "Height":744,
              "ErrCode":0
            },
            {
              "Type":0,
              "Height":0,
              "ErrCode":0
            }
       ]
    },
    "Version": "1.0.0"
}

或 交易池不存在此交易

{
    "Action": "getmempooltxstate",
    "Desc": "UNKNOWN TRANSACTION",
    "Error": 44001,
    "Result": "",
    "Version": "1.0.0"
}

查询交易是否调用成功

查询智能合约推送内容，代表交易执行成功，如果没有成功States中不会有transfer的事件。

ontSdk.getConnect().getSmartCodeEvent("d441a967315989116bf0afad498e4016f542c1e7f8605da943f07633996c24cc")


response:
{
    "Action": "getsmartcodeeventbyhash",
    "Desc": "SUCCESS",
    "Error": 0,
    "Result": {
        "TxHash": "20046da68ef6a91f6959caa798a5ac7660cc80cf4098921bc63604d93208a8ac",
        "State": 1,
        "GasConsumed": 0,
        "Notify": [
            {
                "ContractAddress": "ff00000000000000000000000000000000000001",
                "States": [
                    "transfer",
                    "T9yD14Nj9j7xAB4dbGeiX9h8unkKHxuWwb",
                    "TA4WVfUB1ipHL8s3PRSYgeV1HhAU3KcKTq",
                    1000000000
                ]
            }
        ]
    },
    "Version": "1.0.0"
}

根据块高查询智能合约事件，返回有事件的交易hash

ontSdk.getConnect().getSmartCodeEvent(10)

response:
{
    "Action": "getsmartcodeeventbyheight",
    "Desc": "SUCCESS",
    "Error": 0,
    "Result": [{

2.4 ONT转账

ONT和ONG转账可以一对一，也可以一对多，多对多，多对一。

构造转账交易并发送

转出方与收款方地址：
Address sender = acct0.getAddressU160();
Address recvAddr = acct1;
//多签地址生成
//Address recvAddr = Address.addressFromMultiPubKeys(2, acct1.serializePublicKey(), acct2.serializePublicKey());

构造转账交易：
long amount = 1000;
Transaction tx = ontSdk.nativevm().ont().makeTransfer(sender.toBase58(),recvAddr.toBase58(), amount,sender.toBase58(),30000,0);
String hash = tx.hash().toString()

对交易做签名：
ontSdk.signTx(tx, new com.github.ontio.account.Account[][]{{acct0}});
//多签地址的签名方法：
ontSdk.signTx(tx, new com.github.ontio.account.Account[][]{{acct1, acct2}});
//如果转出方与网络费付款人不是同一个地址，需要添加网络费付款人的签名


发送预执行（可选）：
Object obj = ontSdk.getConnect().sendRawTransactionPreExec(tx.toHexString());
System.out.println(obj);
成功返回：
{"State":1,"Gas":30000,"Result":"01"}
余额不足返回异常：
com.github.ontio.network.exception.RestfulException: {"Action":"sendrawtransaction","Desc":"SMARTCODE EXEC ERROR","Error":47001,"Result":"","Version":"1.0.0"}


发送交易：
ontSdk.getConnect().sendRawTransaction(tx.toHexString());


同步发送交易：
Object obj = ontSdk.getConnect().syncSendRawTransaction(tx.toHexString());

response success:

makeTransfer	String sender，String recvAddr,long amount,String payer,long gaslimit,long gasprice	发送方地址，接收方地址，金额，网络费付款人地址，gaslimit，gasprice
makeTransfer	State[] states,String payer,long gaslimit,long gasprice	一笔交易包含多个转账。

多次签名

如果转出方与网络费付款人不是同一个地址，需要添加网络费付款人的签名

1.添加单签签名
ontSdk.addSign(tx,acct0);

2.添加多签签名
ontSdk.addMultiSign(tx,2,new byte[][]{acct.serializePublicKey(),acct2.serializePublicKey()},acct);
ontSdk.addMultiSign(tx,2,new byte[][]{acct.serializePublicKey(),acct2.serializePublicKey()},acct2);

3.多签签名分多次签
acct0签名：
ontSdk.addMultiSign(tx,2,new byte[][]{acct.serializePublicKey(),acct2.serializePublicKey()},acct);

acct1签名：
ontSdk.addMultiSign(tx,2,new byte[][]{acct.serializePublicKey(),acct2.serializePublicKey()},acct2);

一转多或多转多

构造多个state的交易
签名
一笔交易上限为1024笔转账

Address sender1 = acct0.getAddressU160();
Address sender2 = Address.addressFromMultiPubKeys(2, acct1.serializePublicKey(), acct2.serializePublicKey());
int amount = 10;
int amount2 = 20;

State state = new State(sender1, recvAddr, amount);
State state2 = new State(sender2, recvAddr, amount2);
Transaction tx = ontSdk.nativevm().ont().makeTransfer(new State[]{state1,state2},sender1.toBase58(),30000,0);

//第一个转出方是单签地址，第二个转出方是多签地址：
ontSdk.signTx(tx, new com.github.ontio.account.Account[][]{{acct0}});
ontSdk.addMultiSign(tx,2,new byte[][]{acct1.serializePublicKey(),acct2.serializePublicKey()},acct1);
ontSdk.addMultiSign(tx,2,new byte[][]{acct1.serializePublicKey(),acct2.serializePublicKey()},acct2);

使用签名机签名

构造交易并签名

构造交易，序列化交易，发送交易给签名机
签名机接收到交易，反序列化，检查交易，添加签名
发送交易

序列化交易发送给签名机：
Transaction tx = ontSdk.nativevm().ont().makeTransfer(sender.toBase58(),recvAddr.toBase58(), amount,sender.toBase58(),30000,0);
String txHex = tx.toHexString();

接收方反序列化交易并签名：

Transaction txRx = Transaction.deserializeFrom(Helper.hexToBytes(txHex));


签名：
ontSdk.addSign(txRx,acct0);

SDK与签名机交互：

例子

节点启动时打开签名机服务：
go run SigSvr.go


设置签名机URL：
String url = ip + ":" + "20000/cli";
OntSdk ontSdk = OntSdk.getInstance();
ontSdk.setSignServer(url);
        

String txHex = tx.toHexString();

请求单签交易：
ontSdk.getSignServer().sendSigRawTx(txHex);
 
请求多签交易： 
String[] signs = new String[]{"02039b196d5ed74a4d771ade78752734957346597b31384c3047c1946ce96211c2a7",
                    "0203428daa06375b8dd40a5fc249f1d8032e578b5ebb5c62368fc6c5206d8798a966"};
ontSdk.getSignServer().sendMultiSigRawTx(txHex,2,signs);

请求构造转账交易并签名：
ontSdk.getSignServer().sendSigTransferTx("ont","TU5exRFVqjRi5wnMVzNoWKBq9WFncLXEjK","TA5SgQXTeKWyN4GNfWGoXqioEQ4eCDFMqE",10,30000,0);

对数据做签名

SDK提供直接对数据做签名的接口。例子

com.github.ontio.account.Account acct = new com.github.ontio.account.Account(ontSdk.defaultSignScheme);

byte[] data = "12345".getBytes();
byte[] signature = ontSdk.signatureData(acct, data);

System.out.println(ontSdk.verifySignature(acct.serializePublicKey(), data, signature));

2.5 ONG转账

ONG转账方法与ONT转账类似，但ONG的精度是9。

ONG转账

ontSdk.nativevm().ong().makeTransfer(sender.toBase58(),recvAddr.toBase58(), amount,sender.toBase58(),30000,0);

提取ong

查询是否有ong可以提取
发送提取ong交易

查询未提取ong:
String addr = acct0.getAddressU160().toBase58();
String ong = sdk.nativevm().ong().unboundOng(addr);

//提取ong
com.github.ontio.account.Account account = new com.github.ontio.account.Account(Helper.hexToBytes(privatekey0), ontSdk.signatureScheme);
String hash = sdk.nativevm().ong().withdrawOng(account,toAddr,64000L,payerAcct,30000,500);

3. NEP5转账

参考例子：例子

3.1 查询

String balance = ontSdk.neovm().nep5().queryBalanceOf(acct.address);
System.out.println(new BigInteger(Helper.reverse(Helper.hexToBytes(balance))).longValue());

String totalSupply = ontSdk.neovm().nep5().queryTotalSupply();
System.out.println(new BigInteger(Helper.reverse(Helper.hexToBytes(totalSupply))).longValue());

String decimals = ontSdk.neovm().nep5().queryDecimals();
System.out.println(decimals);

String name = ontSdk.neovm().nep5().queryName();
System.out.println(new String(Helper.hexToBytes(name)));

String symbol = ontSdk.neovm().nep5().querySymbol();
System.out.println(new String(Helper.hexToBytes(symbol)));

System.out.println(Address.decodeBase58(acct.address).toHexString());

3.2 转账

ontSdk.neovm().nep5().sendTransfer(acct,"AVcv8YBABi9m6vH7faq3t8jWNamDXYytU2",46440000L,acct,gasLimit,0);

4. 批量交易

SDK发送注册Ontid和转账等交易时，根据钱包中账户和身份信息解密出私钥再做签名，这个过程大概需要1-2秒时间。为了节省发交易时间，可以多线程或多机器事先创建交易，再批量发送。

实现步骤如下，例子

4.1 批量构造交易

打开文件
构造交易，下面以构造注册Ontid交易为例。
写入交易

构造交易时，如果新创建账户，需要用户自己保存账户私钥。

//open file, make registry ontid transaction, save tx to file.
File file = new File(filePath);
if (!file.exists()) {
    file.createNewFile();
}
com.github.ontio.account.Account payerAcct = new com.github.ontio.account.Account(Helper.hexToBytes(privatekey1), SignatureScheme.SHA256WITHECDSA);
FileOutputStream fos = new FileOutputStream(file);
for (int i = 0; i < 3; i++) {
    com.github.ontio.account.Account account = new com.github.ontio.account.Account(SignatureScheme.SHA256WITHECDSA);
    String ontid = Common.didont + account.getAddressU160().toBase58();
    Transaction tx = ontSdk.nativevm().ontId().makeRegister(ontid, Helper.toHexString(account.serializePublicKey()), payerAcct.getAddressU160().toBase58(), 20000, 500);
    ontSdk.addSign(tx, account);
    ontSdk.addSign(tx, payerAcct);
    System.out.println("PrivateKey:"+Helper.toHexString(account.serializePrivateKey())+",txhash:"+tx.hash().toString());

    fos.write(tx.toHexString().getBytes());
    fos.write(",".getBytes());
    fos.write(tx.hash().toString().getBytes());
    fos.write("\n".getBytes());
}

文件中数据格式：

交易，交易hash
交易，交易hash

4.2 批量发送交易

打开文件
读取一行数据
提取交易数据，发送交易数据

//read transaction from file, send transaction to node
FileReader fr = new FileReader(filePath);
BufferedReader bf = new BufferedReader(fr);
String txHex = null;
while ((txHex=bf.readLine())!=null){
    txHex = txHex.split(",")[0];
    Object obj = ontSdk.getConnect().sendRawTransactionPreExec(txHex);//change to sendRawTransaction
    System.out.println(obj);
}

4.3 在钱包中创建Ontid

如果需要把Ontid保存到钱包，根据4.1中保存的私钥，在钱包中创建Ontid即可。

Identity identity = ontSdk.getWalletMgr().createIdentityFromPriKey(password,privatekey0);
ontSdk.getWalletMgr().writeWallet();
