我正在尝试从我的 web3 应用程序连接到我的 testrpc 实例，但我似乎无法连接。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，currentprovider对象如下。
它似乎只是打印了我认为的对象:

最佳答案
您的连接正常。
要返回帐户数组，请使用 web3.eth.getAccounts() 而不是 web3.eth.accounts。
上面的代码应该看起来像......
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
