3.使用SDK快速体验星火链

本章带大家使用Java SDK 在星火链网体验网上分别部署、调用、查询一个Javascript、Solidity智能合约，需要完成如下工作：

获取星火令来激活账户
Java sdk的初始化
通过体验网部署合约

3.1 SDK使用

通过maven引入星火链Java SDK.

<dependency>
	<groupId>cn.bitfactory</groupId>
	<artifactId>bif-chain-sdk</artifactId>
	<version>1.1.0</version>
</dependency>

3.2 账号创建

调用JavaSDK接口离线创建一个账户。

import cn.bif.model.crypto.KeyPairEntity;
KeyPairEntity entity = KeyPairEntity.getBidAndKeyPair();                //离线创建一个新账号
System.out.printf("BID address %s\n", entity.getEncAddress());          //账户地址, 可以公开
System.out.printf("privatekey %s\n", entity.getEncPrivateKey());      //账户私钥, 请妥善保管

3.3 获取星火令

账户需要拥有星火令才能正常使用星火链功能, 体验网星火令可以通过如下方式获取：

通过星火插件钱包申请可信凭证获取100星火令(需要等待2-3天工作人员审批，着急的话可以在技术交流群找工作人员加急审核，技术交流群见第一章二维码)

星火插件钱包下载地址：https://bitfactory.cn/szsf.html

3.4 初始化SDK

通过配置星火链RPC地址连接SDK到星火链, 本次演示的demo里链接到星火链体验网。

import cn.bif.api.BIFSDK;

public static final String NODE_URL = "http://test.bifcore.bitfactory.cn";  //星火链体验网RPC地址

BIFSDK sdk = BIFSDK.getInstance(NODE_URL);

3.5 查看账户状态

import cn.bif.model.request.BIFAccountGetInfoRequest;
import cn.bif.model.response.BIFAccountGetInfoResponse;

//构建查看账户请求
BIFAccountGetInfoRequest infoReq = new BIFAccountGetInfoRequest();
//要查看账户的地址
infoReq.setAddress(address);

//发出查询请求
BIFAccountGetInfoResponse infoRsp = sdk.getBIFAccountService().getAccount(infoReq);

if (infoRsp.getErrorCode() == 0) {
    //查询成功
    System.out.println(JsonUtils.toJSONString(infoRsp.getResult()));
} else {
    //查询失败
    System.out.println(infoRsp.getErrorDesc());
}

.. ::node
注意, 新创建的空白账户查询会失败, 需要转入星火令激活才能正常使用。

正常账户查询返回示例:

{
    "address":"did:bid:efKkF5uKsopAishxkYja4ULRJhrhrJQU",    //账户地址
    "balance":10000000000,                                   //账户余额
    "nonce":0                                                //账户发出的交易计数
}

3.6 部署调用一个Js合约

3.6.1 智能合约代码

Javascript智能合约代码如下:

"use strict";


function init(input)
{
    const {key, value} = JSON.parse(input);
    Chain.store(key, String(value));
    Chain.tlog('Log', key, String(value));
    return;
}
function store({key, value}) {
    Chain.store(key, String(value));
    Chain.tlog('Log', key, String(value));
}

function del({key}) {
    Chain.del(key);
}

function main(input)
{
    let {method, params} = JSON.parse(input);
    if (method === 'store')
  {
        store(params);
    } else if (method === 'del') {
        del(params);
    }
}

function get({key}) {
    return Chain.load(key);
}
function query(input)
{
    let {method, params} = JSON.parse(input);
    if (method === 'get') {
        return get(params);
    }
}

该合约实现了一个简单的存储功能, 用户可以调用main接口存储自定义Key-Value信息, 然后通过查询接口查询已经存入的Key-Value信息。

3.6.2 部署合约

合约编写完毕后, 需要将合约部署到链上, 注意这里需要账户内有足够的XHT, 部署代码如下:

	//发起交易的账户，使用上面生成的账户地址
  String senderAddress = "did:bid:efzE8AcDgWUeNbgujA5hK3oUeuG9k19b";
	//发起交易的账户的私钥，用上面生成的私钥
  String senderPrivateKey = "priSPKiwJR7PwjN3bGPRvXRoC6Dny1H5H3kASHgTEugjtUDknW";
	//合约代码，注意双引号转义
  String   payload =  "\"use strict\"; function init(input) {     const {key, value} = JSON.parse(input);     Chain.store(key, String(value));     Chain.tlog('Log', key, String(value));     return; } function store({key, value}) {     Chain.store(key, String(value));     Chain.tlog('Log', key, String(value)); }  function del({key}) {     Chain.del(key); }  function main(input) {     let {method, params} = JSON.parse(input);     if (method === 'store')     {         store(params);     } else if (method === 'del') {         del(params);     } }  function get({key}) {     return Chain.load(key); } function query(input) {     let {method, params} = JSON.parse(input);     if (method === 'get') {         return get(params);     } }";

  //给合约账户的初始化金额，如无需求可以设置为0
  Long initBalance = ToBaseUnit.ToUGas("0");

  BIFContractCreateRequest request = new BIFContractCreateRequest();
  request.setSenderAddress(senderAddress);
  
  //SDK本地内部
  request.setPrivateKey(senderPrivateKey);
  request.setInitBalance(initBalance);
  request.setPayload(payload);
  request.setInitInput("{\"key\":\"test\",\"value\":2}");
  //备注，选填
	request.setRemarks("create contract");
	//type，javascript合约type为0，solidity合约type为1
	request.setType(0);
  //feelimit设置要小于账户的balance
	request.setFeeLimit(100060000L);
  request.setNonceType(1);

	// 调用contractCreate接口
	BIFContractCreateResponse response = sdk.getBIFContractService().contractCreate(request);
	if (response.getErrorCode() == 0) {
  	System.out.println(JsonUtils.toJSONString(response.getResult()));
	} else {
  	System.out.println(JsonUtils.toJSONString(response));
	}

如果部署成功, 调用返回里会拿到这个交易的hash:

{
      "hash":"92313f8fb30b042a4d3f4d276ee2d4ce59f21994deed53e6cc6e2a2dcbe61f8f"
}

交易信息和合约地址查询

用SDK查询部署合约的交易详细信息, 可以从中获取到创建的合约地址。

//部署返回hash
String hash = "92313f8fb30b042a4d3f4d276ee2d4ce59f21994deed53e6cc6e2a2dcbe61f8f";
BIFContractGetAddressRequest request = new BIFContractGetAddressRequest();
request.setHash(hash);

// 调用接口
BIFContractGetAddressResponse response = sdk.getBIFContractService().getContractAddress(request);
if (response.getErrorCode() == 0) {
    System.out.println(JsonUtils.toJSONString(response.getResult()));
} else {
    System.out.println(JsonUtils.toJSONString(response));
}

合约部署信息示例如下:

{
    "contract_address_infos":[
        {
            "contract_address":"did:bid:ef6ZAWV315UracvhKARdHz5CbQ6dULPp",
            "operation_index":0
        }
    ]
}

did:bid:ef6ZAWV315UracvhKARdHz5CbQ6dULPp即为刚刚创建的合约链上地址。

交易信息和合约地址查询用SDK根据合约地址查询合约账户的内容：

BIFContractGetInfoRequest request = new BIFContractGetInfoRequest();
//上面返回的合约地址
request.setContractAddress("did:bid:efXkBsC2nQN6PJLjT9nv3Ah7S3zJt2WW");
 BIFContractGetInfoResponse response = sdk.getBIFContractService().getContractInfo(request);
if (response.getErrorCode() == 0) {
    System.out.println(JsonUtils.toJSONString(response.getResult()));
} else {
   System.out.println(JsonUtils.toJSONString(response));
}

查询内容结果如下：

{
	"contract":{
	"type":0,
"payload":"\"use strict\"; function init(input) {     const {key, value} = JSON.parse(input);     Chain.store(key, String(value));     Chain.tlog('Log', key, String(value));     return; } function store({key, value}) {     Chain.store(key, String(value));     Chain.tlog('Log', key, String(value)); }  function del({key}) {     Chain.del(key); }  function main(input) {     let {method, params} = JSON.parse(input);     if (method === 'store')     {         store(params);     } else if (method === 'del') {         del(params);     } }  function get({key}) {     return Chain.load(key); } function query(input) {     let {method, params} = JSON.parse(input);     if (method === 'get') {         return get(params);     } }"
}
}

3.6.3 合约调用

合约成功部署并且获取到合约地址后, 就可以通过SDK发送交易调用合约接口, 我们存储一个Key-Value对到合约里:

调用合约input如下

{
    "key":"test",
    "value": 123
}

调用合约代码如下:

// 初始化参数
String senderAddress = "did:bid:efzE8AcDgWUeNbgujA5hK3oUeuG9k19b";
String contractAddress = "did:bid:ef6ZAWV315UracvhKARdHz5CbQ6dULPp";
String senderPrivateKey = "priSPKiwJR7PwjN3bGPRvXRoC6Dny1H5H3kASHgTEugjtUDknW";
Long amount = 0L;
String input = "{\"method\":\"store\",\"params\":{\"key\":\"test\",\"value\":123}}";
BIFContractInvokeRequest request = new BIFContractInvokeRequest();
request.setSenderAddress(senderAddress);
request.setPrivateKey(senderPrivateKey);
request.setContractAddress(contractAddress);
request.setBIFAmount(amount);
request.setRemarks("contract invoke");
request.setInput(input);
request.setNonceType(1);

// 调用contractInvoke 接口
BIFContractInvokeResponse response = sdk.getBIFContractService().contractInvoke(request);
if (response.getErrorCode() == 0) {
    System.out.println(JsonUtils.toJSONString(response.getResult()));
} else {
    System.out.println(JsonUtils.toJSONString(response));
}

调用成功后，我们会得到调用交易的hash：

{
    "hash":"2fcb88fcab04af78e4d06ec263d462b2aacd00d9405159725918d9ca8144ea5d"
}

利用交易哈希查询调用结果：

BIFTransactionGetInfoRequest request = new BIFTransactionGetInfoRequest();
//上面返回的哈希值
request.setHash("2fcb88fcab04af78e4d06ec263d462b2aacd00d9405159725918d9ca8144ea5d");
BIFTransactionGetInfoResponse response =  sdk.getBIFTransactionService().getTransactionInfo(request);
if (response.getErrorCode() == 0) {
	System.out.println(JsonUtils.toJSONString(response.getResult()));
} else {
	System.out.println(JsonUtils.toJSONString(response));
}

打印结果为：

{"total_count":1,"transactions":[{"actual_fee":"290","close_time":1711676430063002,"error_code":0,"error_desc":"","hash":"5d1a11f0ab56b3780c784ca57f2815872395cc0a813c0f64b45b98167b770972","ledger_seq":3800392,"signatures":[{"sign_data":"b9135e2c402b05a66e4a23dec493e12eebe43b5a58205b0bca87ee78dd43b649a6cc97a3d7f3c16f486a7320125a3a00b16ad6d6dde8e15436acf0b786757301","public_key":"b06566ef31937a34b42d2ed56c8fd132920709b92aeca7dc96c22e38d270822d9e1318"}],"transaction":{"source_address":"did:bid:ef4w8cwj7W1C27cZc46SCpsAi3nASBwB","fee_limit":1000000,"gas_price":1,"nonce":141,"metadata":"636f6e747261637420696e766f6b65","operations":[{"type":7,"pay_coin":{"dest_address":"did:bid:efiqdeCKdn1b3wX4oWC25KckyqKLG33j","input":"{\"key\":\"test\", \"value\": 123}"}}]},"tx_size":290}]}

3.6.4 查询合约

不同于调用合约, 查询合约为只读操作, 因此不需要发出上链交易和耗费gas, 这里我们查询刚刚设置的key, 查询input为:

{
    "key":"test"
}

Java查询代码如下:

// 初始化参数
String contractAddress = "did:bid:ef6ZAWV315UracvhKARdHz5CbQ6dULPp";
String callInput = "{\"method\":\"get\",\"params\":{\"key\":\"test\"}}";
BIFContractCallRequest request = new BIFContractCallRequest();
request.setContractAddress(contractAddress);
request.setInput(callInput);

// 调用contractQuery接口
BIFContractCallResponse response = sdk.getBIFContractService().contractQuery(request);
if (response.getErrorCode() == 0) {
    BIFContractCallResult result = response.getResult();
    System.out.println(JsonUtils.toJSONString(result));
} else {
    System.out.println(JsonUtils.toJSONString(response));
}

查询的返回如下:

{
    "query_rets":[
        {
            "result":
                {
                    "type":"string",//查询结果字段的类型
                    "value":"123"//查询结果字段的值
                }
        }
    ]
}

3.7部署调用一个 Solidity合约

3.7.1 智能合约代码

Solidity智能合约代码如下:

pragma solidity ^0.8.20;

contract Storage  {
  mapping(uint256 => string) private _datas;
  mapping(uint256=>bool) private _exists;
  event Log(uint256 , string);

  constructor(uint256 id, string memory data) public {
    _datas[id] = data;
    _exists[id] = true;
    emit Log(id, data);
  }

  function queryById(uint256 id) public view returns (string memory) {
    require(!_exists[id], "data not exists");
    return _datas[id];
  }
  function setById(uint256 id, string memory data) public payable {
    require(_exists[id], "data has exists");
    _datas[id] = data;
  }
}

该合约实现了一个简单的存储功能, 用户可以调用setById接口存储自定义Key-Value信息, 然后通过queryById接口查询已经存入的Key-Value信息。

3.7.2 智能合约编译

交易信息和合约地址查询

//部署返回hash
String hash = "d525a576173e2606acb33103eca5e3cc5c0106c67833a2b75d67d3164cec6b12";
