## 1. 釋義 查詢指定節點上已經安裝的鏈碼，或者查詢指定通道中實例化的鏈碼。 ## 2. 使用方法 ``` ~$ peer chaincode list [flags] ``` ## 3. 命令標志 ``` -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 ``` 全局標志： ``` --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 ``` ## 4. 示例代碼 下面的示例代碼使用`--installed`標志列出在當前peer節點上安裝的鏈碼： ``` ~$ 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，節點已經安裝了名為mycc的鏈碼，其版本為1.0。 下面的示例使用`--instantiated`與`-C`(通道ID)的組合來列出指定通道上實例化的鏈碼： ``` ~$ 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，版本為1.0的鏈碼mycc已經在通道mychannel上實例化了。
