## 1. 釋義 將指定節點加入到一個通道中。 ## 2. 使用方法 ``` ~$ peer channel join [flags] ``` ## 3. 命令標志 ``` -b, --blockpath string Path to file containing genesis block -h, --help help for join ``` 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 ``` ## 4. 示例代碼 下面的示例將peer節點加入到文件`./mychannel.genesis.block`中包含的創世塊中定義的通， 該通道區塊文件是之前使用`peer channel fetch`命令獲取到的： ``` ~$ peer channel join -b ./mychannel.genesis.block 2018-02-25 12:25:26.511 UTC [channelCmd] InitCmdFactory -> INFO 003 Endorser and orderer connections initialized 2018-02-25 12:25:26.571 UTC [channelCmd] executeJoin -> INFO 006 Successfully submitted proposal to join channel 2018-02-25 12:25:26.571 UTC [main] main -> INFO 007 Exiting..... ``` 可以看到peer節點已經成功地提交了加入通道的請求。
