## 1. 释义 将指定的链码打包为CDS（Chaincode Deployment Spec：链码部署规范）格式。 ## 2. 使用方法 ``` ~$ peer chaincode package [flags] ``` ## 3. 命令标志 ``` -s, --cc-package create CC deployment spec for owner endorsements instead of raw CC deployment spec -c, --ctor string Constructor message for the chaincode in JSON format (default "{}") -h, --help help for package -i, --instantiate-policy string instantiation policy for the chaincode -l, --lang string Language of chaincode, either "golang" (default), "node", or "java" -n, --name string Name of the chaincode -p, --path string Path to chaincode, for "golang" use relative path from $GOPATH/src, for "node" or "java" use absolute path -S, --sign if creating CC deployment spec package for owner endorsements, also sign it with local MSP -v, --version string Version of the chaincode specified in install/instantiate/upgrade commands ``` 全局标志： ``` --cafile string Path to file containing PEM-encoded trusted certificate(s) for the ordering endpoint --certfile string Path to file containing PEM-encoded X509 public key to use for mutual TLS communication with the orderer endpoint --clientauth Use mutual TLS when communicating with the orderer endpoint --connTimeout duration Timeout for client to connect (default 3s) --keyfile string Path to file containing PEM-encoded private key to use for mutual TLS communication with the orderer endpoint -o, --orderer string Ordering service endpoint --ordererTLSHostnameOverride string The hostname override to use when validating the TLS connection to the orderer. --tls Use TLS when communicating with the orderer endpoint --transient string Transient map of arguments in JSON encoding ``` ## 4. 示例代码 下面的示例使用`peer chaincode package`命令将版本1.1的mycc链码进行打包，然后 使用本地MSP签名，最后输出位ccpack.out： ``` ~$ peer chaincode package ccpack.out -n mycc -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02 -v 1.1 -s -S . . . 2018-02-22 17:27:01.404 UTC [chaincodeCmd] checkChaincodeCmdParams -> INFO 003 Using default escc 2018-02-22 17:27:01.405 UTC [chaincodeCmd] checkChaincodeCmdParams -> INFO 004 Using default vscc . . . 2018-02-22 17:27:01.879 UTC [chaincodeCmd] chaincodePackage -> DEBU 011 Packaged chaincode into deployment spec of size <3426>, with args = [ccpack.out] 2018-02-22 17:27:01.879 UTC [main] main -> INFO 012 Exiting..... ```
