Hyperledger Sawtooth：Javascript 中的交易处理器

Question

我正在尝试根据以下示例在 javascript SDK 中实施交易处理器

https://github.com/hyperledger/sawtooth-core/blob/master/sdk/examples/intkey_javascript/index.js

这是我在 javascript SDK

中运行交易处理器的代码

//validator public key
const validatorAddress = '024c512a6d66917d7d00f52fa299a88594915dab27bddbcd2a80154984d7948c3c';

const IntegerKeyHandler = require('./handler');

const startProcessor = function startProcessor(){

    const transactionProcessor = new TransactionProcessor(validatorAddress);

    transactionProcessor.addHandler(new IntegerKeyHandler())

    transactionProcessor.start()

}

但我收到无效参数错误

Answer 1

将验证器地址更改为验证的url，可以是tcp://validator:4004或tcp://localhost:4004

完整代码如下：

'use strict'

const { TransactionProcessor } = require('sawtooth-sdk/processor')
const IntegerKeyHandler = require('./integer_key_handler')

const address = 'tcp://validator:4004' // If you are not running it inside docker container then change the address to this tcp://localhost:4004

const transactionProcessor = new TransactionProcessor(address);

transactionProcessor.addHandler(new IntegerKeyHandler());

transactionProcessor.start();
