在AWS Lambda上解锁帐户web3.js1.0

Question

当试图解锁AWS Lambda上的帐户时，我收到以下错误消息：

Error: Node error: {"code":-32601,"message":"The method personal_unlockAccount does not exist/is not available"}
    at Function.validate (/var/task/node_modules/web3-providers/dist/web3-providers.cjs.js:111:18)
    at HttpProvider._callee$ (/var/task/node_modules/web3-providers/dist/web3-providers.cjs.js:674:61)

    at process._tickDomainCallback (internal/process/next_tick.js:228:7)

'use strict';

const AWS = require('aws-sdk');
AWS.config.update({region: 'ap-northeast-1'});
const documentClient = new AWS.DynamoDB.DocumentClient();

const Web3 = require('web3');  
const web3 = new Web3(new Web3.providers.HttpProvider(process.env['INFURA_ENDPOINT']));
const abiSource = require('./lib/myToken.json');
const abi = abiSource.abi;
const contractAddress = process.env['CONTRACT_ADDRESS'];
const myToken = web3.eth.Contract(abi, contractAddress);

.
.
.

exports.handler = async (event, context) => {
  event = event.body || event;
  const senderAddress = event.sender_address;
  const privateKey = event.private_key;
  try{
    await web3.eth.personal.unlockAccount(senderAddress, privateKey, 600);
  }catch(error){
    console.log(error);
    return getResponse(200, 'Internal server error');
  }

  .
  .
  .
};

我的合同部署在Ropsten网络上，不过下面我有一些处理事务的代码，这会引发同样的错误。有什么想法可以解决这个/错误的原因吗？

您需要为lambda安装一个web3层。有关如何做到这一点，请参见https://github.com/scenarex/web3-lambda-layer。
