Question

我在ElasticSearch上非常虚伪，我对NodeJs的经验很少。我使用NodeJs + MongoDb创建了一些cruds。我必须从MongoDb更改为ElasticSearch（这是必需的）。请，我不想将MOngoDb与ElasticSearch进行比较，所以不要试试。

我正在关注此处的示例

https://blog.raananweber.com/2015/11/24/simple-autocomplete-with-elasticsearch-and-node-js/

我已成功开始使用ElasticSearch。我可以看到：

nodejs express.js-elasticsearch-autocomplete-demo-master # curl --noproxy -XGET 'http://127.0.0.1:9200/?pretty'
{
  "name" : "-em7X-s",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "cqJUaPcFREe4wX_YyYWoFg",
  "version" : {
    "number" : "5.2.1",
    "build_hash" : "db0d481",
    "build_date" : "2017-02-09T22:05:32.386Z",
    "build_snapshot" : false,
    "lucene_version" : "6.4.1"
  },
  "tagline" : "You Know, for Search"
}

但是，当我尝试启动上面的示例或访问时，我会明显地得到错误：

/dev/samples/express.js-elasticsearch-autocomplete-demo-master $ npm start

> autocompleter@0.0.0 start /home/demetrio/dev/samples/express.js-elasticsearch-autocomplete-demo-master

我很困惑要检查什么。任何建议将不胜感激。我的最终目标是了解如何从NodeJs应用程序连接到ElasticSearch

响应错误请求node_modules / elasticsearch / src / lib / transport.js：264：15
