web3.eth.getAccounts 不适用于 infura

Question

PS: am using web3 beta-37 (Since every version has its own issues) Anything under the line web3.eth.getAccounts in the deploy function isn't working. When i run the code it just shows nothing! Here is the code:

const HDWalletProvider = require('truffle-hdwallet-provider');
const Web3 = require('web3');
const {interface , bytecode} = require('./compile');

const provider = new HDWalletProvider(mnemonic,
'https://rinkeby.infura.io/v3/my_project_id');

const web3 = new Web3(provider);

const deploy = async() => {
    const accounts = await web3.eth.getAccounts();
    console.log('Attempting to deploy from account', accounts[0]);
    const result = await new web3.eth.Contract(JSON.parse(interface))
                             .deploy({data: bytecode, arguments: ['Hi There!']})
                             .send({'from': accounts[0], 'gas': '1000000'});

    console.log('Contract deployed to: ', result.options.address);
};
deploy();

Also, testing this in mocha shows error while it works when using ganache-cli

const assert = require('assert');
const HDWalletProvider = require('truffle-hdwallet-provider');
const Web3 = require('web3');
const {bytecode , interface} = require('../compile');

const provider = new HDWalletProvider(mnemonic,
'https://rinkeby.infura.io/v3/project_id');



let accounts;

beforeEach(async () => {
  //Get a list of all accounts
  accounts = await web3.eth.getAccounts();

});

describe('Inbox', () => {
  it('address', () => {
    assert.ok(accounts);
  })

Here are the results with different versions: beta-46: Cannot read property map() of undefined One answer on stackexchange says use beta-36 to fix this issue

beta-36 and beta-37: Nothing after the getAccounts() statement gets executed, blank screen.

beta-26: core.addProviders is not a function

Answer 1

I also had the same issue.

Try to remove the "/v3" part from the infura url:

const provider = new HDWalletProvider(mnemonic,
'https://rinkeby.infura.io/my_project_id');

Hope this helps.
