使用語言的驅動程式連接

驅動程式連接到您的部署所需的所有資訊都位於在服務憑證頁。 表格包含參照的明細。

• 0... 表示陣列中可能有一或多個這些項目。

當在連線資訊的 "composed" 欄位中找到 URI 格式的連線字串時，許多 Elasticsearch 驅動程式都可以建立與部署的連線。 請參閱下列範例：

下列範例使用 Java 來連接。

import io.searchbox.client.JestClientFactory;
import io.searchbox.client.JestResult;
import io.searchbox.client.config.HttpClientConfig;
import io.searchbox.client.JestClient;
import io.searchbox.cluster.Health;
import org.apache.http.conn.ssl.SSLConnectionSocketFactory;
import org.apache.http.ssl.SSLContextBuilder;

import javax.net.ssl.SSLContext;
import java.io.File;
import java.security.*;
import java.security.cert.CertificateException;


import java.io.IOException;


public class ESConnect {

    public static void main(String[] args) {

        // Add CA cert to truststore using something like:
        //  keytool -import -alias mycert -file /path/to/cert -keystore ./mycert -storetype pkcs12 -storepass mysecret
        // and use the path of the keystore below
        File truststore = new File("/Users/code/java-example/icdcerts");

        try {
            // use your secret and add the variable containing the truststore that you created above with the secret as a CharArray
            SSLContext sslContext = new SSLContextBuilder().loadTrustMaterial(truststore, "mysecret".toCharArray()).build();

            SSLConnectionSocketFactory sslSocketFactory = new SSLConnectionSocketFactory(sslContext);

            // set up a Jest factory
            JestClientFactory factory = new JestClientFactory();

            //configure and build Jest HTTP client with IBM Cloud Databases for Elasticsearch connection strings
            factory.setHttpClientConfig(
                    // add the Elasticsearch host and port
                    new HttpClientConfig.Builder("https://60d1b41b-2478-4767-9fc0-d99b1d00b6d1.bkvfu0nd0m8k95k94ujg.databases.appdomain.cloud:31347")
                            .multiThreaded(true)
                            // Add the credentials username and password
                            .defaultCredentials("admin", "mypassword")
                            .sslSocketFactory(sslSocketFactory)
                            .build());

            // create a JestClient
            JestClient client = factory.getObject();
            // create the call for the cluster health
            Health health = new Health.Builder().build();
            // get the cluster health as a JestResult
            JestResult result = client.execute(health);
            // print out the cluster's health
            System.out.printf("\n\n<------ CLUSTER HEALTH ------>\n%s\n\n", result.getJsonObject());
            // shutdown the connection
            client.close();

        } catch (IOException | KeyStoreException | NoSuchAlgorithmException | KeyManagementException | CertificateException e) {
            e.printStackTrace();
        }

    }

}

下列範例使用 Python 程式庫 elasticsearch-py 來連接。

from elasticsearch import Elasticsearch
from ssl import create_default_context


context = create_default_context(cafile="path/to/cert.pem")

es = Elasticsearch(
    ['60d1b41b-2478-4767-9fc0-d99b1d00b6d1.bkvfu0nd0m8k95k94ujg.databases.appdomain.cloud'],
    http_auth=('admin', 'password'),
    port='31347',
    ssl_context=context
)

health = es.cluster.health()
print(health)

驅動程式 TLS 和服務專屬憑證支援

Databases for Elasticsearch 的所有連線都已啟用 TLS 1.2，因此您用來連接的驅動程式需要能夠支援加密。 您的部署還隨附服務專屬憑證，因此驅動程式可以在連線時驗證伺服器。

如需相關資訊，請參閱 Cloud Databases 憑證常見問題(FAQ)。
