Thor Java Client SDK

A SDK for client to call Restful API.

1、Query the transactions, account, blocks, receipt, blockRef, .

You can find the code from test code as follows:

@Test
	public void testGetBestBlock(){
		Block block = blockchainAPI.getBestBlock();
        logger.info("BestBlock Info  " + block);
        Assert.notNull(block, "BEST BLOCK IS NULL");
	}


	@Test
    public void testGetBlockByNumber(){
        Block block = blockchainAPI.getBlockByNumber(4);
        logger.info("Getting Block Info  " + JSON.toJSONString(block));
        Assert.notNull(block, "BLOCK IS NULL");
    }


    @Test
    public void testGetBlockByid(){
        Block block = blockchainAPI.getBlockById("0x000000016e44c77ae7b7b804df6af935586ecf641869ea479b0eb17b594b3fd5");
        logger.info("Getting Block Info  " + JSON.toJSONString(block));
        Assert.notNull(block, "BLOCK IS NULL");
    }

    @Test
    public void testGetBalance(){
        Account account = blockchainAPI.getBalance("0x7567D83b7b8d80ADdCb281A71d54Fc7B3364ffed","best");
        String balanceString =  account.getBalance();
        logger.info("Current block balance:" +balanceString);
        logger.info("balance: " + BytesUtils.balance(balanceString, 18, 2).toString());
        Assert.notNull(account, "Account is null");
    }

    @Test
    public void testGetBlockRef(){
        byte[] blockRef = blockchainAPI.getBestBlockRef();
        logger.info("Block reference: " + BytesUtils.toHexString(blockRef, Prefix.ZeroLowerX));
    }

2、Post raw transaction.

2.1 The detail step as follows

- 1. Construct a raw transaction Of RawTransaction class without signature.
- 2. Encode the raw transaction with RLP.
- 3. Use blake2b 32 bytes algrithm to hash the rlp encoded transaction
- 4. Sign the hash with private key.
- 5. Construct a raw transaction of RawTransaction class with signature.
- 6. Encode the raw transaction with RLP
- 7. Convert the encoded byte array to hex string with '0x'.
- 8. Post the Json string to VeChain blockchain node.

2.2 You can find all apis in BlockchainAPI.java

3、Create wallet and serialized to keystore string, load keystore and decrypt keypair.

You can find all apis in WalletAPI.java

3. How to run the test

3.1 First you need to replace with the your blockchain node address in BaseTest.java under test directory .

```
@Before
public void setProvider() {
		blockchainAPI = new BlockchainAPIImpl();
		NodeProvider provider = new NodeProvider();
		provider.setProvider("<your thor node address>");
		provider.setTimeout(5000);
		blockchainAPI.setProvider(provider);
}
```

3.2 Run the test.

Some case may be failed because of the account or block is not existed on your blockchain env.

```
    mvn clean install
```
