Hyperledger Fabric 专题 - Fabric 的重要日志输出

假设存在下列 docker 容器。

dev-peer0.org1.example.com-dfgchaincode-1.0
dev-peer1.org1.example.com-dfgchaincode-1.0
dev-peer0.org2.example.com-dfgchaincode-1.0

peer0.org1.example.com
peer1.org1.example.com
peer0.org2.example.com
peer1.org2.example.com

我们只监控了下列 docker 容器的日志：

1. 接口 add(key, value)

当链码接口 add(key, value) 被调用时，链码进程和对端节点进程的重要输出日志。

1.1 链码重要的日志输出

当发生一次链码接口调用时，会产生如下输出。最重要的是注意 onChaincodeMessage，同时 payload 中包含接口名、参数的 BASE64 编码格式。

}

如 "payload": "CgNhZGQKBWZpbGUwCiJ7ImtleSI6ICJmaWxlMCIsICJ2YWx1ZSI6ICJmaWxlMCJ9" BASE64 解码后为：

�add
�file0
"{"key": "file0", "value": "file0"}

同时，还会输出下列重要的日志，注意与接口 add(file,value) 相关的部分以及一些格式化的日志，如 Got invoke routing request 等：

01:31:37:389 FINE    org.hyperledger.fabric.contract.execution.impl.ContractExecutionService executeR Routing Requestadd @2eb669a6

还有调用成功的日志输出：

2. 接口 query(key)

当链码接口 query(key) 被调用时，链码进程和对端节点进程的重要输出日志。

下面的日志大部分和上面的日志类似部分就不再作解释了，独特的部分会指出来。

4. 涉及私有数据

需要注意的是，当涉及私有数据的存储操作时候，另一个组织的链码节点也会有相类似的日志输出。

对应链码节点返回的私有数据，仍然是私有数据本身，而非私有数据的哈希。这也是容易理解的，因为具有权限的组织本身就存储私有数据本身。
