彈性搜索和 nodejs 連接

Question

我正在嘗試使用 rest api 創建一個 node.js 應用程序，以查詢彈性搜索應用程序雲上存在的數據。 我遵循 elasticsearch 連接的代碼

var elasticsearch = require('elasticsearch');

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

上面的連接正確連接，如果我添加任何數據，它也會被添加..但我希望數據不被添加到本地主機..我希望我的實際集群擁有數據..我嘗試了下面的代碼

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
        })
    })

上面的代碼仍然沒有添加數據或從我的雲集群中檢索數據... Evrrywhere on internet I found only localhost examples.. 請問誰能告訴我如何將nodejs直接連接到彈性搜索雲集群？

確保使用 Elastic Cloud UI 提供的 Cloud ID：

然后使用創建部署時創建的憑據。 或者，您也可以創建 API 密鑰進行身份驗證：

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

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

我有同樣的問題。 因此，連接到您的企業搜索的主機 url 將起作用。 像這樣

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

如果這不起作用，請嘗試node:"https://<username>:<password>@<ip1><port>"

您還可以通過將 url 提供為主機 url 數組來一次連接到多個主機。
