6.3.4 Hyperledger Besu接入说明

  1. 使用Geth控制台与节点进行交互。

• 示例：

    [root@localhost ~]# geth attach 
    https://admin:123456@bsn91000001.bsngate.com:19602/node1
  
    INFO [07-15|13:41:24.391] Running with private transaction manager disabled - quorum private transactions will not be supported
    WARNING: call to admin.getNodeInfo() failed, unable to determine consensus mechanism
    Welcome to the Geth JavaScript console!
  
    instance: besu/v21.1.2/linux-x86_64/oracle_openjdk-java-11

    modules: eea:1.0 eth:1.0 ibft:1.0 net:1.0 perm:1.0 priv:1.0 web3:1.0
  
    > web3.eth.blockNumber  
    202
    >
  

  2. 使用JSON-RPC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://besu.hyperledger.org/en/stable/Reference/API-Methods/

  可以使用curl和Postman进行调用。

• 示例：

     [root@localhost ~]# curl -H "Content-Type: application/json" -d \
     >   '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":2}' \ 
     >  https://admin:123456@bsn91000001.bsngate.com:19602/node1
  
    {
        "jsonrpc":"2.0",
        "id":2,
        "result":"0x365"
    }
  

  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);
