使用方法

~$ peer chaincode list [flags]

命令标志

  -C, --channelID string               The channel on which this command should be executed
      --connectionProfile string       Connection profile that provides the necessary connection information for the network. Note: currently only supported for providing peer connection information
  -h, --help                           help for list
      --installed                      Get the installed chaincodes on a peer
      --instantiated                   Get the instantiated chaincodes on a channel
      --peerAddresses stringArray      The addresses of the peers to connect to
      --tlsRootCertFiles stringArray   If TLS is enabled, the paths to the TLS root cert files of the peers to connect to. The order and number of certs specified should match the --peerAddresses flag

全局标志：

      --cafile string                       Path to file containing PEM-encoded trusted certificate(s) for the ordering endpoint
      --certfile string                     Path to file containing PEM-encoded X509 public key to use for mutual TLS communication with the orderer endpoint
      --clientauth                          Use mutual TLS when communicating with the orderer endpoint
      --connTimeout duration                Timeout for client to connect (default 3s)
      --keyfile string                      Path to file containing PEM-encoded private key to use for mutual TLS communication with the orderer endpoint
  -o, --orderer string                      Ordering service endpoint
      --ordererTLSHostnameOverride string   The hostname override to use when validating the TLS connection to the orderer.
      --tls                                 Use TLS when communicating with the orderer endpoint
      --transient string                    Transient map of arguments in JSON encoding

示例代码

下面的示例代码使用--installed标志列出在当前peer节点上安装的链码：

~$ peer chaincode list --installed
Get installed chaincodes on peer:
Name: mycc, Version: 1.0, Path: github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02, Id: 8cc2730fdafd0b28ef734eac12b29df5fc98ad98bdb1b7e0ef96265c3d893d61
2018-02-22 17:07:13.476 UTC [main] main -> INFO 001 Exiting.....

可以看到，节点已经安装了名为mycc的链码，其版本为1.0。

下面的示例使用--instantiated与-C(通道ID)的组合来列出指定通道上实例化的链码：

~$ peer chaincode list --instantiated -C mychannel
Get instantiated chaincodes on channel mychannel:
Name: mycc, Version: 1.0, Path: github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02, Escc: escc, Vscc: vscc
2018-02-22 17:07:42.969 UTC [main] main -> INFO 001 Exiting.....

可以看到，版本为1.0的链码mycc已经在通道mychannel上实例化了。
