CryptoCurrency NODE.js Web3以太网-无法连接到TESTRPC

Question

我正在尝试从我的web3应用程序连接到我的testrpc实例，但是我似乎无法连接。下面的代码应该返回testrpc链中所有帐户的数组。

代码：

Web3 = require('web3')
web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545"));
console.log(web3.eth.accounts);

它返回下面的内容，在对象intelliJ中，当前的提供者对象如下所示。

​

它似乎只是打印了我认为的对象：

Answer 1

您的连接工作正常。

要返回帐户数组，请使用web3.eth.getAccounts()而不是web3.eth.accounts。

上面的代码应该类似于...

Web3 = require('web3')
web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545"));
web3.eth.getAccounts().then(accounts => console.log(accounts));

给你一些类似的东西..。
