3. Channel management

Use the peer channel command to perform channel operations (you can enter the peer channel --help command to view the use of specific commands)

for example: list all application channels that the peer has joined

peer channel list

 for example: Obtain the basic information of the channel (height, current hash, hash of the leading block)

peer channel getinfo -c mychannel

 4. Management node

Use the peer node command to perform channel operations, and you can use peer node --help to view specific instructions

Note: The operation on the node needs to be performed when the Peer service is stopped

5. Management chain code

Chaincode is divided into system chaincode and user chaincode; usually chaincode refers to user chaincode.

Use the peer lifecycle chaincode command to operate, you can use peer lifecycle chaincode --help to view the specific instructions 

for example: view the chaincode installed on the node

peer lifecycle chaincode queryinstalled

 for example: Call the chain code to query the assets of user A

peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'

-C, the channel name where the chain code is located

-n, chaincode name

-c, parameters transmitted to the chaincode Invoke method
