Hyperledger fabric 理解Hyperledger结构块提取,hyperledger-fabric,extract,block,hyperledger,Hyperledger Fabric,Extract,Block,Hyperledger,我想更好地了解hyperledger fabric 1.4.2块的块结构以及其中发生的事情。因此，我使用了FabCar示例，进行了一次更新过程，并提取了这个相关块下载此块进行分析后，我使用以下代码对其进行解码： peer channel fetch 5 mychannel5.block -c mychannel docker cp peer0.org1.example.com:/opt/gopath/src/github.com/hyperledger/fabric ./configtxl

我想更好地了解hyperledger fabric 1.4.2块的块结构以及其中发生的事情。因此，我使用了FabCar示例，进行了一次更新过程，并提取了这个相关块

下载此块进行分析后，我使用以下代码对其进行解码：

peer channel fetch 5 mychannel5.block -c mychannel 
docker cp peer0.org1.example.com:/opt/gopath/src/github.com/hyperledger/fabric
./configtxlator proto_decode --input mychannel5.block --type common.Block > block5

下面是块的摘录：

在这里，我想知道，里面有字节的较长行的内容是什么，比如： 1.背书人（签字部分） 2.id_字节（顶部：） 3.值（在我更新的事务中）

我希望有一个可读的字节版本。我如何转换或解码它们？例如，对于背书人，我希望在那里显示的字节后面有一个证书和一个公钥

谢谢大家!

通常，Hyperledger结构中类似的内容都是Base64编码的

“id_bytes”字段是提议块的对等方（这里是org2的对等方，因为mspid是org2MSP）的管理证书的base64编码版本。如果将其粘贴到Base64解码器（如此解码器）中，您应该会看到与您在artifacts/crypto config/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/msp/admincerts下找到的证书相同的证书

“背书人”字段是在Base64编码后，背书对等方（即为块签名的对等方）的signcert。这里有两个代言人。您可以在artifacts/crypto config/peerOrganizations/org0.example.com/peers/peer0.org0.example.com/msp/signcerts下找到签名证书

“值”部分只是用于事务的参数，再次使用Base64编码（例如，这里的参数是{“make”：“Honda”，“model”：“Accord”，“Color”：“black”，“owner”：“Tom”}，正如您在解码后看到的那样）。
