专有节点接入说明

在完成项目的创建后，系统会为每个项目创建对应框架所需要的接入信息，用户在访问区块链节点时进行接入授权验证，通过验证后即可访问链上。

Quorum

GoQuorum

使用GoQuorum client与节点进行交互。

示例：

$   ./geth attach https://VuF0h0y7pLwtvDqjuW:y2sYuiIciR6JFtHbmC@bsnmu7d0gNn.bsngate.com:19602/node1
INFO [05-08|16:05:52.534] Running with private transaction manager disabled - quorum private transactions will not be supported 
Welcome to the Geth JavaScript console!

JSON-RPC API

Geth JSON-RPC文档: https://github.com/ethereum/wiki/wiki/JSON-RPC
Quorum API文档: https://docs.goquorum.consensys.net/en/latest/Reference/APIs/PrivacyAPI/

可以使用curl和Postman进行调用。

示例：

$ curl -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":2}' https://VuF0h0y7pLwtvDqjuW:y2sYuiIciR6JFtHbmC@bsnmu7d0gNn.bsngate.com:19602/node1

{"jsonrpc":"2.0","id":2,"result":"0x10"}

web3.js

web3.js类库：https://github.com/ethereum/web3.js

示例：

const Web3 = require("web3");

const web3 = new Web3(
new Web3.providers.HttpProvider("https://VuF0h0y7pLwtvDqjuW:y2sYuiIciR6JFtHbmC@bsnmu7d0gNn.bsngate.com:19602/node1")
);

web3.eth.getBlockNumber().then(console.log);

fabric

Tools

使用fabric-tools与节点进行交互。

示例：

启动cli：

# docker-compose-cli.yaml文件如下：
$ cat docker-compose-cli.yaml 
version: '2'
services:
cli:
    container_name: fabric_peercli
    image: hyperledger/fabric-tools:2.2.0
    restart: always
    tty: true
    stdin_open: true
    environment:
    - FABRIC_LOGGING_SPEC=DEBUG
    - CORE_PEER_TLS_ENABLED=true  
    - CORE_PEER_TLS_ROOTCERT_FILE=/etc/hyperledger/fabric/tls/ca.crt
    - CORE_PEER_ADDRESS=peer1.org1.example.com:1051
    - CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/fabric/msp
    - CORE_PEER_LOCALMSPID=Org1MSP
    - ORDERER_CA=/etc/hyperledger/fabric/orderer/tlsca/tlsca.orderer.example.com-cert.pem
    - ORDERER_ADDRESS=orderer1.orderer.example.com:7050
    working_dir: /etc/hyperledger/fabric
    command: /bin/bash
    volumes:
    - /var/run/:/host/var/run/
    - ./certs/ordererOrganizations/orderer.example.com:/etc/hyperledger/fabric/orderer
    - ./certs/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp:/etc/hyperledger/fabric/msp
    - ./certs/peerOrganizations/org1.example.com/peers/peer1.org1.example.com/tls:/etc/hyperledger/fabric/tls
    - ./sharedfiles/chaincode:/etc/hyperledger/fabric/src
    extra_hosts:
    - "orderer1.orderer.example.com:161.189.69.75"
    - "peer1.org1.example.com:161.189.69.75"

进入容器进行链码部署以及调用：

#链码部署

// install

//ReadAsset
peer chaincode query -C netchannel -n basic414 -c '{"Args":["ReadAsset","asset7"]}'

chain33
