如何连接moto独立服务器？

Question

我刚刚安装了moto，并尝试使用以下node.js代码连接到独立服务器：

const AWS = require('aws-sdk')
const ep = new AWS.Endpoint('http://127.0.0.1:5000')
const route53 = new AWS.Route53({endpoint: ep})

const params = {}
console.log(route53.listHostedZones(params))

这段代码设置了亚马逊网络服务的endpoint，它指向moto的独立服务器。然后向端点发送listHostedZones请求。此程序的输出为

    extractError: [ [Function: extractError], [Function: extractRequestId] ],
    httpError: [ [Function: ENOTFOUND_ERROR] ] },
emit: [Function: emit] }

正如您在上面的输出中所看到的，其中存在一个ENOTFOUND_ERROR错误。而且我在moto的控制台输出中找不到任何新的连接。

我开始moto的方式是moto_server route53

> moto_server route53
* Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

我的配置有什么问题？我想我的node.js代码有问题。我误解了endpoint的含义吗？
