弹性搜索和 nodejs 连接

如何解决弹性搜索和 nodejs 连接

我正在尝试使用 rest api 创建一个 node.js 应用程序来查询弹性搜索应用程序云上存在的数据。我遵循了弹性搜索连接的代码

var elasticsearch = require('elasticsearch');

var client = new elasticsearch.Client({
    host:'localhost:9200'
});

上述连接正确连接，如果我添加任何数据，它也会被添加..但我希望数据不被添加到本地主机..我希望我的实际集群拥有数据.. 我试过下面的代码

var elasticsearch = require('elasticsearch');

var client = new elasticsearch.Client({
    cloud: {
        id: 'cloud_id',},auth: {
        username: "username",password: "pass",});

//data I am trying to add

let data = {
    "id": "park_somethign","title": "Something","description": "Split into the separate Rincon Mountain and Tucson Mountain districts,this park is evidence that the dry Sonoran Desert is still home to a great variety of life spanning six biotic communities. Beyond the namesake giant saguaro cacti,there are barrel cacti,chollas,and prickly pears,as well as lesser long-nosed bats,spotted owls,and javelinas.","nps_link": "https://www.nps.gov/sagu/index.htm","states": [
        "Arizona"
    ],"visitors": 838456,"world_heritage_site": false,"location": "32.20,-109.5","acres": 9215.72,"square_km": 2271.2,"date_established": "1997-10-14T05:00:00Z"
}

//this is what I am trying to do
 client.index({
        index: 'engines',body: data
    }).then(resp => {
        return res.status(200).json({
            message: "Added Data"
        })
    }).catch(e => {
        console.log(e)
        return res.status(500).json({
            message: "Error",e
        })
    })

上面的代码仍然没有添加数据或从我的云集群中检索数据... 在互联网上的任何地方我只找到了 localhost 示例.. 请谁能告诉我如何将 nodejs 直接连接到弹性搜索云集群？

解决方法

确保使用 Elastic Cloud UI 提供的 Cloud ID：

然后使用创建部署时创建的凭据。或者，您也可以创建 API 密钥来进行身份验证：

const { Client } = require('@elastic/elasticsearch')

const client = new Client({
  cloud: {
    id: 'name:bG9jYWxob3N0JGFiY2QkZWZnaA==',},auth: {
    apiKey: {
      id: 'foo',api_key: 'bar'
    }
  }
})

我有同样的问题。因此，连接到企业搜索的主机 url 将起作用。像这样

var client = new elasticsearch.Client({
// do not forget to add the username and password in the url
  host:"https://<username>:<password>[complete_host_url]" 
}); 

如果这不起作用，请尝试node:"https://<username>:<password>@<ip1><port>"

您还可以通过将 url 作为主机 url 数组提供来一次连接到多个主机。
