fabric区块解析【附源码】

Fabric命令手册
获取通道配置区块 需要开启tls服务认证 与 ca证书认定
获取最新区块
获取指定高度的区块
获取通道信息
解析区块
1 获取通道区块

区块链创世区块为高度为0的区块 节点通过创世区块加入通道 通过oldest或高度为0获取

peer channel fetch oldest mychannel.block -c mychannel -o orderer.example.com:7050 --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

2 获取通道内最新的区块

peer channel fetch newest new.block -c mychannel -o orderer.example.com:7050 --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

3获取指定高度的区块

peer channel fetch 8  -c mychannel --orderer orderer.example.com:7050 --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

4 获取通道信息

peer channel getinfo -c mychannel

5解析区块 区块为追溯区块
区块交易

解码区块数据为json数据

../bin/configtxlator proto_decode --input trace.block --type common.Block --output trace.json
