fabric鍊碼查詢







peer chaincode query
常用參數
-n --name 		chaincode的名字
-C --channelID	目前指令運作的通道,預設testchainid
-c --ctor   	JSON格式的構造參數,預設"{}"

執行一下
peer chaincode query -n abccc -C abcchannel -c '{"Args":["query", "a"]}'

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





我們查詢一下然後看下結果
[email protected]:/opt/gopath/src/github.com/hyperledger/fabric/peer# peer chaincode query -n abccc -C abcchannel -c '{"Args":["query", "a"]}'
100



然後我們再查詢一下b
peer chaincode query -n abccc -C abcchannel -c '{"Args":["query", "b"]}'

[email protected]:/opt/gopath/src/github.com/hyperledger/fabric/peer# peer chaincode query -n abccc -C abcchannel -c '{"Args":["query", "b"]}'
200










然後我們要通過用戶端切換peer節點

```shell
$ docker exec -it cli bash
# 用戶端預設會連接配接某一個節點
CORE_PEER_ADDRESS=peer0.orggo.abc.com:7051
# 對用戶端進行操作, 操作的是預設連接配接的節點
```

```shell
看docker-compose 配置檔案中關于 用戶端容器的設定 -> 環境變量
CORE_PEER_ADDRESS=peer0.orggo.abc.com:7051 # 用戶端連接配接的peer節點
CORE_PEER_LOCALMSPID=OrgGoMSP

打包一下
peer chaincode package -n abccc -v 1.0 -p github.com/chaincode mycc.out



1.peer channel list

2.peer channel join -b abcchannel.block

3.peer chaincode install mycc.out

4.
