This release runs on testnets only and fixed the issue of parameters in eth_subscribe method.
Now the VNODE will support all four parameters in eth_subscribe method:

  • newHeads
  • logs
  • newPendingTransactions
  • syncing

To enable the JSON-RPC notifications, VNODE client needs to start with ws options.
For example, using the following parameters instead of "rpc".

moac --testnet --ws --wsaddr 0.0.0.0 --wsport 8546 --wsapi "chain3,mc,net,db,personal" --wsorigins "*"

本次发布版本仅用于测试网络,修复了eth_subscribe接口中支持参数的问题,使得用户可以在提供websocket接口的客户端订阅信息。
目前可以订阅的信息包括:

  • newHeads
  • logs
  • newPendingTransactions
  • syncing

为了使用订阅功能,需要VNODE客户端在启动时候使用"ws"选项:

moac --testnet --ws --wsaddr 0.0.0.0 --wsport 8546 --wsapi "chain3,mc,net,db,personal" --wsorigins "*"

然后,在web3中使用订阅功能

const Web3 = require('web3')
const web3 = new Web3("wss://localhost:8546")

function newBlockHeaders(){
  var subscription = eth.subscribe('newBlockHeaders', function(error, result){
      
        if (!error){
            console.log(result);
        }else{
            console.log(error);
        }
    })
    .on("data", function(transaction){
        console.log(`transaction:${transaction}`);
    })
}

// Start listening to different events
newBlockHeaders();
