一個EOS的Java實現(Android平臺也可使用)

簡介：

這是一個EOS的Java端實現，本庫可以創建EOS的公私鑰，查詢餘額，交易，投票，EOS的account綁定，離線簽名等，幾乎所有EOS的操作。

歡迎star

- Use it

1. 首先添加 Bip44ForJava 依賴

implementation ‘party.52it:Bip44ForJava:1.0.0’

2. 生成 EOS相關的公鑰私鑰

3. 具體使用代碼實例

System.out.println("============= 自定義數據簽名 ===============");
		String sign = Ecc.sign(pk,"is京東價as看到可可是是是@#￥%……&*（CVBNM《d ");
		System.out.println("sign :" + sign + " \n ");
		
		System.out.println("============= 轉賬數據序列化 ===============");
		String data = Ecc.parseTransferData("fromaccount", "toaccount", "10.0020 SYS", "測試123abcdo./,./!@##$%");
		System.out.println("seriz data :" + data);
		System.out.println("transfer eq eosjs seriz " + data.equals(eosjs_transfer_seriz)+" \n ");

		System.out.println("============= 創建賬戶數據序列化 ===============");
		String data1 = Ecc.parseAccountData("eosio", "espritbloc1.","EOS8eAX54cJtAngV2V22WZhRCW7e4sTAZz1mC5U22vp8mAGuFdMXx","EOS8FPooohZiiCAYXahWCQRxgXXzUbS2gNELAeYCUgGdDMbd2FHQT");
		System.out.println("seriz data :" + data1);
		System.out.println("account eq eosjs seriz " + data1.equals(eosjs_account_seriz));

		
		System.out.println("\n******************* Ecc End *******************\n\n\n");
		
		System.out.println("******************* Rpc Start *******************\n");
		
		Rpc rpc = new Rpc("http://47.106.221.171:8888");
		
		System.out.println("============= 轉賬 ===============");
		try {
			Transaction t1 = rpc.transfer("5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3","espritblocke", "inita","initb", "12.2821 MSP", "");
			System.out.println("轉賬成功 = " + t1.getTransactionId()+" \n ");
		}catch(Exception ex) {
			ex.printStackTrace();
		}
		
		System.out.println("============= 創建賬戶並且抵押 ===============");
		try {	
			Transaction t2 = rpc.createAccount("5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3","eosio","ccccc..bbbbb", "EOS8eAX54cJtAngV2V22WZhRCW7e4sTAZz1mC5U22vp8mAGuFdMXx","EOS8eAX54cJtAngV2V22WZhRCW7e4sTAZz1mC5U22vp8mAGuFdMXx", 8192l, "0.01 SYS","0.01 SYS", 0l);
			System.out.println("創建成功 = " + t2.getTransactionId()+" \n ");
		}catch(Exception ex) {
			ex.printStackTrace();
		}
		System.out.println("============= 創建賬戶不抵押 ===============");
		try {	
			Transaction t3 = rpc.createAccount("5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3","eosio","bbbb..54321", "EOS8eAX54cJtAngV2V22WZhRCW7e4sTAZz1mC5U22vp8mAGuFdMXx","EOS8eAX54cJtAngV2V22WZhRCW7e4sTAZz1mC5U22vp8mAGuFdMXx", 8192l);
			System.out.println("創建成功 = " + t3.getTransactionId()+" \n ");
		}catch(Exception ex) {
			ex.printStackTrace();
		}
		
		System.out.println("============= 代理投票 ===============");
		try {
			List<String> produces = new ArrayList<>();
			produces.add("pppppeeeeooo");
			produces.add("mdddssssddds");
			produces.add("mdjddjddddds");
			rpc.voteproducer("5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3", "epskdkdsddss","iuewjdkslsdc",produces);
		} catch (Exception e) {
			e.printStackTrace();
		}
		
		System.out.println("============= 關閉餘額爲0的token ===============");
		try {
			rpc.close("5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3", "合約賬戶", "關閉賬戶", "0.0000 IPOS");
		}catch(ApiException e) {
			e.printStackTrace();
		}catch(Exception ex) {
			ex.printStackTrace();
		}
		System.out.println("\n******************* Rpc End *******************");

4. 離線簽名

public static void testOfflineCreate() {
		Rpc rpc = new Rpc("http://47.106.221.171:8888");
		// 獲取離線簽名參數
		SignParam params = rpc.getOfflineSignParams(60l);
		// 離線簽名
		OfflineSign sign = new OfflineSign();
		// 交易信息
		String content = "";
		try {
			content = sign.createAccount(params, "5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3", "eeeeeeeeeeee",
					"555555555551", "EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV",
					"EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV", 8000l);
			System.out.println(content);
		} catch (Exception e) {
			e.printStackTrace();
		}
		// 廣播交易
		try {
			Transaction tx = rpc.pushTransaction(content);
			System.out.println(tx.getTransactionId());
		} catch (ApiException ex) {
			System.out.println(ex.getError().getCode());
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

	public static void testOfflineTransfer() {
		Rpc rpc = new Rpc("http://47.106.221.171:8888");
		// 獲取離線簽名參數
		SignParam params = rpc.getOfflineSignParams(60l);
		// 離線簽名
		OfflineSign sign = new OfflineSign();
		// 交易信息
		String content = "";
		try {
			content = sign.transfer(params, "5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3", "eosio.token",
					"eeeeeeeeeeee", "555555555551", "372.0993 EOS", "test");
			System.out.println(content);
		} catch (Exception e) {
			e.printStackTrace();
		}
		// 廣播交易
		try {
			Transaction tx = rpc.pushTransaction(content);
			System.out.println(tx.getTransactionId());
		} catch (ApiException ex) {
			System.out.println(ex.getError().getCode());
		} catch (Exception e) {
			e.printStackTrace();
		}
