# eosRpcJ

#### 项目介绍
 
对接eos rpc api，包括以下功能：

-  1.获取区块链信息
-  2.创建新账号
-  3.查询账户余额
-  4.充值处理
-  5.离线签名转账
-  6.资源抵押、赎回
-  7.ram购买、售出

#### 使用说明

1. 测试类如下：

```

public class EosApiTest {

    //测试网络
    final static EosApi eosRpcService = new EosApi("https://api-kylin.eosasia.one");
    //正式网络
    //final static EosApi eosRpcService = new EosApi("https://proxy.eosnode.tools");

    final static  String privateKey = "5KezfC7aGLn9K6DGumST6iCzTdDZvd1Tt6F2T8gDKCVJVu9PX9p";//填写你的账户私钥

    //1.获取区块链信息
    @Test
    public void getChainInfo() {
        long t1 = System.currentTimeMillis();
        ChainInfo chainInfo = eosRpcService.getChainInfo();
        long t2 = System.currentTimeMillis();
        System.out.println(JSON.toJSON(chainInfo));
        System.out.println("time:" + (t2 - t1));
    }

    //2.创建新账号
    @Test
    public void createAccount() {
        Transaction transaction = null;
        try {
            //生成新的秘钥对
            String owner = "";
            Map keyMap = eosRpcService.generateKey();
            if (keyMap != null) {
                owner = keyMap.get(EosApi.K_publicKey).toString();
            }
            transaction = eosRpcService.createAccount(privateKey,
                    "linqihong123", "linqihong115", owner, owner, 4096l);
        } catch (ApiException e) {
            ApiError apiError = e.getError();
            System.out.println("code:" + apiError.getError().getCode());
            System.out.println("msg:" + apiError.getError().getWhat());
            if (apiError.getError().getCode().equals("3050001")) {
                System.out.println("该账户名已经被占用");
            }
        } catch (EException e) {
            System.out.println(e.getCode());
            System.out.println(e.getMsg());
        } catch (Exception e) {
            e.printStackTrace();
        }
        System.out.println(JSON.toJSON(transaction));
    }

    //3.查询账户余额
    @Test
    public void balance() {
        double balance = eosRpcService.getBalance("linqihong123");
        System.out.println(balance);
    }


    //5.充值处理
    @Test
    public void recharge() throws Exception {
        List<String> accountList = new ArrayList<>();
        accountList.add("linqihong123");
        List<Action> actions = eosRpcService.getActions(accountList);
        System.out.println(JSON.toJSONString(actions));
    }

    //6.生成秘钥对
    @Test
    public void generateKey() throws Exception {
        Map resultMap = eosRpcService.generateKey();
        System.out.println("resultMap:" + resultMap);
    }

    //7.获取账户信息
    @Test
    public void getAccount() {
        Account account = eosRpcService.getAccount("linqihong123");
        System.out.println(JSON.toJSONString(account));
    }

    //8.转账
    @Test
    public void transfer() {
        Transaction transaction = null;
        try {
            transaction = eosRpcService.transfer(privateKey, "linqihong123", "linqihong124", 1, "hhahah");
        } catch (ApiException e) {
            ApiError apiError = e.getError();
            if (apiError.getError().getCode().equals("3080002")) {
                System.out.println("交易超出了对交易强加的当前网络使用限制");
            }
            System.out.println("code:" + apiError.getError().getCode());
            System.out.println("msg:" + apiError.getError().getWhat());

        } catch (Exception e) {
            e.printStackTrace();
        }
        System.out.println(JSON.toJSONString(transaction));
    }

    //9.计算创建账户的费用：fee=1.005*内存（kb）*汇率+ 抵押cpu的EOS + 抵押net的EOS
    @Test
    public void getRate() {
        double rate = eosRpcService.getRate();
        double fee = 1.005 * 3 * rate;
        System.out.println(fee);
    }



    //10.抵押资源-以租借的方式
    @Test
    public void delegatebw1() throws Exception {
        Transaction transaction = eosRpcService.delegatebw(privateKey, "linqihong123", "linqihong124", 1, 1, 0L);
        System.out.println(JSON.toJSONString(transaction));
    }

    //11.抵押资源-以赠送的方式
    @Test
    public void delegatebw2() throws Exception {
        Transaction transaction = eosRpcService.delegatebw(privateKey, "linqihong123", "linqihong124", 1, 0, 1L);
        System.out.println(JSON.toJSONString(transaction));
    }

    //12.赎回资源
    @Test
    public void unDelegatebw() throws Exception {
        Transaction transaction = eosRpcService.unDelegatebw(privateKey, "linqihong123", "linqihong124", 1, 1);
        System.out.println(JSON.toJSONString(transaction));
    }

    //13.购买内存
    @Test
    public void buyRam() throws Exception {
        Transaction transaction = eosRpcService.buyRam(privateKey, "linqihong123", "linqihong124", 2*1024L);
        System.out.println(JSON.toJSONString(transaction));
    }

    //14.销售内存
    @Test
    public void sellRam() throws Exception {
        Transaction transaction = eosRpcService.sellRam(privateKey, "linqihong123", 1024L);
        System.out.println(JSON.toJSONString(transaction));
    }
