6.3.1 Consensys Quorum 接入说明

  1. 使用GoQuorum client与节点进行交互

• 示例：

    $   ./geth attach 
    https://VuF0h0y7pLwtvDqjuW:y2sYuiIciR6JFtHbmC@bsnmu7d0gNn.bsngate.com:19602/node1

    modules: admin:1.0 debug:1.0 eth:1.0 istanbul:1.0 miner:1.0 net:1.0 personal:1.0 rpc:1.0 txpool:1.0 web3:1.0
  
    > web3.eth.blockNumber
  
    11

  2. 使用JSON-RPC API与节点进行交互

• 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.bsngatecom:19602/node1
  
    {"jsonrpc":"2.0","id":2,"result":"0x10"}

  3. 使用web3.js与节点进行交互

• web3.js类库：https://github.com/ChainSafe/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);
