Hyperledger fabric 單機docker cli 啟動及查詢轉賬操作

啟動Fabric

現在所有檔案都已經準備完畢，我們可以啟動我們的Fabric網路了。 啟動orderer

讓我們首先來啟動orderer節點，在orderer伺服器上運行：

docker-compose -f docker-compose-cli.yaml up 

運行完畢後我們可以使用docker ps看到運行了一個名字為orderer.example.com的節點。

[root@iz2zeivrkckulq2dtidztmz e2e_cli]# docker-compose -f docker-compose-cli.yaml up WARNING: The CHANNEL_NAME variable is not set. Defaulting to a blank string.WARNING: The TIMEOUT variable is not set.

解決方案

1）第一種：這裡我們將Python的預設編碼方式修改為utf-8，就可以規避上述問題的發生，具體方式，我們在Python檔案的前面加上如下代碼：import sysdefaultencoding = 'utf-8'if sys.getdefaultencoding() != defaultencoding:    reload(sys)    sys.setdefaultencoding(defaultencoding) 2）第二種：我們在/usr/lib/python2.7/site-packages/目錄下添加一個sitecustomize.py檔案，內容如下：import syssys.setdefaultencoding('utf-8') 這種方式可以解決所有項目的encoding問題，具體說明可參考/usr/lib/python2.7/site.py檔案：

docker-compose -f docker-compose-cli.yaml down

執行命令

docker run -it cli bash

異常：

[root@iz2zeivrkckulq2dtidztmz e2e_cli]# docker exec -it cli bashError response from daemon: Container 1f9b6f7d709f263f4a67a67ad91b419b13844efaaa4caeb6dd571bfa829822c7 is not running

解決方案：

cli:    container_name: cli...   working_dir: /opt/gopath/src/github.com/hyperledger/fabric/peer   # command: /bin/bash -c './scripts/script.sh ${CHANNEL_NAME} ${DELAY}; sleep $TIMEOUT'    volumes:        - /var/run/:/host/var/run/...

注釋

command: /bin/bash -c './scripts/script.sh ${CHANNEL_NAME} ${DELAY}; sleep $TIMEOUT'

進入cli執行

./scripts/script.sh mychannel

查詢

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

轉帳

peer chaincode invoke -o orderer.example.com:7050  --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem  -C mychannel -n mycc -c '{"Args":["invoke","a","b","20"]}'
