使用非SSL方式连接实例的Java代码示例

package influxdb;

import okhttp3.OkHttpClient;
import org.influxdb.InfluxDB;
import org.influxdb.InfluxDBFactory;
import org.influxdb.dto.Point;
import org.influxdb.dto.Query;
import org.influxdb.dto.QueryResult;

import java.util.concurrent.TimeUnit;

public class demoNoSSL {
    public static void main(String[] args) {
        OkHttpClient.Builder client = new OkHttpClient.Builder()
                .connectTimeout(10, TimeUnit.SECONDS)
                .writeTimeout(10, TimeUnit.SECONDS)
                .readTimeout(10, TimeUnit.SECONDS)
                .retryOnConnectionFailure(true);

        final String serverURL = "http://127.0.0.1:8086", username = "root", password = "root";
        InfluxDB influxdb = InfluxDBFactory.connect(serverURL, username, password, client);

        // Create a database...
        String databaseName = "foo";

        influxdb.query(new Query("CREATE DATABASE " + databaseName, databaseName));
        influxdb.setDatabase(databaseName);

        // Write points to influxdb.
        influxdb.write(Point.measurement("bar")
                .time(System.currentTimeMillis(), TimeUnit.MILLISECONDS)
                .tag("location", "chengdu")
                .addField("temperature", 22)
                .build());

        // Query your data using InfluxQL.
        QueryResult queryResult = influxdb.query(new Query("SELECT * FROM bar", databaseName));

        // Close it if your application is terminating or you are not using it anymore.
        influxdb.close();
    }
}
