Fabric的区块信息（结合SDK-java）

获取区块信息的方法

通过Fabric-sdk-java中的End2EndIT.blockwalker中获取的信息

前置条件：知道区块链的Channel。

本文没有列全相关类的方法，某些需要的信息可能还需要查看fabric-sdk-java来确定。

获取区块链信息

1	BlockchainInfo channelInfo = channel.queryBlockchainInfo();

区块信息

// 根据区块号获取
BlockInfo returnedBlock = channel.queryBlockByNumber(blockNumber); 
// 根据交易ID获得
BlockInfo returnedBlock = channel.queryBlockByTransactionID(txid);
// 根据Hash获得
BlockInfo returnedBlock = channel.queryBlockByHash(hash);// 根据Hash获得
// 获取Hash
// 数据的Hash
Hex.encodeHexString(returnedBlock.getDataHash())；
// 前一个区块的Hash
Hex.encodeHexString(returnedBlock.getPreviousHash())； 
// 计算出当前区块的Hash
// *************BlockHash = cal(blockNumber,block.preHash,DataHash)*****************
Hex.encodeHexString(SDKUtils.calculateBlockHash(client, 
                        blockNumber, returnedBlock.getPreviousHash(), returnedBlock.getDataHash()));
// 获取信封的个数
returnedBlock.getEnvelopeCount();

交易信息

// 获取信封信息
returnedBlock.getEnvelopeInfos()
for(lockInfo.EnvelopeInfo envelopeInfo : returnedBlock.getEnvelopeInfos())

envelopeInfo = returnedBlock.getEnvelopeInfo(0);

// 获取当前信封的交易ID
String txid = envelopeInfo.getTransactionID();
// 获取当前信封所在的通道
String channelId = envelopeInfo.getChannelId();
// 交易时间戳
out("  Transaction number %d has transaction timestamp: %tB %<te,  %<tY  %<tT %<Tp", i, envelopeInfo.getTimestamp());
// 随机数[生成特定要求的Hash用的]
Hex.encodeHexString(envelopeInfo.getNonce());
// 交易创建者
String MSPID = envelopeInfo.getCreator().getMspid();
// 创建者证书   
String cert = envelopeInfo.getCreator().getId();

如果交易类型是TRANSACTION_ENVELOPE可以有更多的信息

// 将信封强制转换为(BlockInfo.TransactionEnvelopeInfo)
BlockInfo.TransactionEnvelopeInfo transactionEnvelopeInfo = (BlockInfo.TransactionEnvelopeInfo) envelopeInfo;
// 获取一个交易中action的个数【目前，每个交易只有一个action】
transactionEnvelopeInfo.getTransactionActionInfoCount());
// 交易是否有效,区块链中所有提交的交易都会被放进区块链，只有有效的才会改状态数据库
transactionEnvelopeInfo.isValid());
// 有效码
transactionEnvelopeInfo.getValidationCode())；
// 获取所有交易Action信息
transactionEnvelopeInfo.getTransactionActionInfos()

交易Action信息(目前区块链1.4.4只支持一个action)

// 获取交易状态
transactionActionInfo.getResponseStatus()； // 200
// 交易响应信息
transactionActionInfo.getResponseMessageBytes()；
// 交易背书者个数
transactionActionInfo.getEndorsementsCount()；// 2

// 获取背书者信息
BlockInfo.EndorserInfo endorserInfo = transactionActionInfo.getEndorsementInfo(n);
// 背书者签名
Hex.encodeHexString(endorserInfo.getSignature())
// 背书者MspID和证书
endorserInfo.getMspid()； endorserInfo.getId()；

// 调用合约的参数
transactionActionInfo.getChaincodeInputArgsCount()；// 参数个数
// 获取第z个参数
String arg1 = new String(transactionActionInfo.getChaincodeInputArgs(z), UTF_8)；
/*
   Transaction action 1 has 4 chaincode input arguments // 交易参数
     Transaction action 1 has chaincode input argument 0 is: invoke
     Transaction action 1 has chaincode input argument 1 is: a
     Transaction action 1 has chaincode input argument 2 is: b
     Transaction action 1 has chaincode input argument 3 is: 10
*/

// 合约响应
String responce = new String(transactionActionInfo.getProposalResponsePayload())));
// 合约名字
String chaincodeIDName = transactionActionInfo.getChaincodeIDName();
// 合约版本
String chaincodeIDVersion = transactionActionInfo.getChaincodeIDVersion();
// 合约路径
String chaincodeIDPath = transactionActionInfo.getChaincodeIDPath();


// 交易读写集
TxReadWriteSetInfo rwsetInfo = transactionActionInfo.getTxReadWriteSet();
// 迭代获得每个name space read write set
rwsetInfo.getNsRwsetInfos();
// 迭代器获得单个命名空间
String namespace = nsRwsetInfo.getNamespace();
// 读写集
KvRwset.KVRWSet rws = nsRwsetInfo.getRwset();
rws.getReadsList()
rws.getWritesList()

//out("Namespace %s read set %d key %s  version [%d:%d]", namespace, rs, readList.getKey(),readList.getVersion().getBlockNum(), readList.getVersion().getTxNum());
//     Namespace mycc read set 0 key a  version [3:0]
KvRwset.KVRead readList. : rws.getReadsList()
readList.getVersion().getBlockNum(); //区块号
readList.getVersion().getTxNum()); //交易号
/*获取某个版本下某个key对应的值，如在启动完byfn：a has value 90 */
//out("Namespace %s write set %d key %s has value '%s' ", namespace, rs,writeList.getKey(),valAsString);
//     Namespace mycc write set 0 key a has value '90' 
writeList.getKey()；
new String(writeList.getValue().toByteArray(), UTF_8)；

byfn启动后的区块信息

/**

*/
