}

二、如何查看区块

1. 查看区块链信息

docker exec [container] peer channel getinfo -c [channel]#返回如下信息
Blockchain info: {"height":3,"currentBlockHash":"MvXGp1W3jK7vnn5V0dGZAgg7iIadjLCl1ArCh5XHXHs=","previousBlockHash":"BxXo7hCkE6Gb4Y/KDi0M85dw/8d7S4BU1hvcVz0DQJw="} #区块链高度为3，区块链的编号为0, 1, 2,其中0是创世区块

2. 获取区块文件

#获取区块链文件
docker exec [container] peer channel fetch [block-number] -c [channel]
#区块文件保存在当前文件夹，文件名为[channel]_[block-number].block
#拷贝区块文件到宿主机器当前文件夹
docker cp [container]:/opt/gopath/src/github.com/hyperledger/fabric/peer/[channel]_[block-number].block ./

3. 解析区块文件

使用fabric-samples中的二进制工具configtxgen解析区块文件，可以将configtxgen所在文件夹添加到PATH中。再查看环境变量中是否有FABRIC_CFG_PATH，没有的话要设置成configtx.yaml所在文件夹，否则configtxgen会找不到配置文件。

#将区块文件解析成json文件
configtxgen -inspectBlock [.block file] > [.json file]

三、解析

1. 区块结构

为了增强可读性，可以用在线工具将json转成yaml

---
header: data_hash: ...number: ...previous_hash: ...
data: data: -   payload: ...signature: ...
metadata: metadata: ...

可以看到一个区块包括三部分：

区块头：包含当前区块哈希、区块序号、前一区块的哈希；
区块数据：交易组成的数组
元数据：和当前区块相关的元数据

2. 交易结构

signature: ...
payload: header: channel_header: ...        //包括txid、时间戳、通道等信息signature_header: ... //包括sender的证书、mspid、随机数noncedata: actions: -    header: payload: ...

可以看到一个交易包括：交易发送者的签名、数据载荷payload。
payload又包含两部分：

header
data: 包括一个由action组成的数组

下面看看action包含哪些东西

actions:
-   header: ... //和signature_header一样payload: chaincode_proposal_payload: ...   //请求智能合约的函数名、参数等action: endorsements: ...   //背书者的id组成的数组proposal_response_payload: ... //链码模拟执行结果对KV类型状态数据库的读写集
