Search Trend

This section describes examples of Search Trend API that analyze trend data statistics from NAVER Unified Search by age, gender, and search environment.

Java

The following is a Java-based sample code for the Search Trend API.

import java.io.BufferedReader;
import java.io.DataOutputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

public class APIExamDatalabTrend {

    public static void main(String[] args) {
        String clientId = "YOUR_CLIENT_ID";
        String clientSecret = "YOUR_CLIENT_SECRET";

        try {
            String apiURL = "https://naveropenapi.apigw.ntruss.com/datalab/v1/search";
            String body = "{\"startDate\":\"2017-01-01\",\"endDate\":\"2017-04-30\",\"timeUnit\":\"month\",\"keywordGroups\":[{\"groupName\":\"Korean\",\"keywords\":[\"Korean\",\"korean\"]},{\"groupName\":\"English\",\"keywords\":[\"English\",\"english\"]}],\"device\":\"pc\",\"ages\":[\"1\",\"2\"],\"gender\":\"f\"}";
            URL url = new URL(apiURL);
            HttpURLConnection con = (HttpURLConnection)url.openConnection();
            con.setRequestMethod("POST");
            con.setRequestProperty("X-NCP-APIGW-API-KEY-ID", clientId);
            con.setRequestProperty("X-NCP-APIGW-API-KEY", clientSecret);
            con.setRequestProperty("Content-Type", "application/json");

            con.setDoOutput(true);
            DataOutputStream wr = new DataOutputStream(con.getOutputStream());
            wr.write(body.getBytes());
            wr.flush();
            wr.close();

            int responseCode = con.getResponseCode();
            BufferedReader br;
            if(responseCode==200) { 
                br = new BufferedReader(new InputStreamReader(con.getInputStream()));
            } else {  
                br = new BufferedReader(new InputStreamReader(con.getErrorStream()));
            }

            String inputLine;
            StringBuffer response = new StringBuffer();
            while ((inputLine = br.readLine()) != null) {
                response.append(inputLine);
            }
            br.close();
            System.out.println(response.toString());

        } catch (Exception e) {
            System.out.println(e);
        }
    }
}

Python

The following is a Python-based sample code for the Search Trend API.

import os
import sys
import urllib.request
client_id = "YOUR_CLIENT_ID"
client_secret = "YOUR_CLIENT_SECRET"
url = "https://naveropenapi.apigw.ntruss.com/datalab/v1/search";
body = "{\"startDate\":\"2017-01-01\",\"endDate\":\"2017-04-30\",\"timeUnit\":\"month\",\"keywordGroups\":[{\"groupName\":\"Korean\",\"keywords\":[\"Korean\",\"korean\"]},{\"groupName\":\"English\",\"keywords\":[\"English\",\"english\"]}],\"device\":\"pc\",\"ages\":[\"1\",\"2\"],\"gender\":\"f\"}";

request = urllib.request.Request(url)
request.add_header("X-NCP-APIGW-API-KEY-ID",client_id)
request.add_header("X-NCP-APIGW-API-KEY",client_secret)
request.add_header("Content-Type","application/json")
response = urllib.request.urlopen(request, data=body.encode("utf-8"))
rescode = response.getcode()
if(rescode==200):
    response_body = response.read()
    print(response_body.decode('utf-8'))
else:
    print("Error Code:" + rescode)

PHP

The following is a PHP-based sample code for the Search Trend API.

<?php

$client_id = "YOUR_CLIENT_ID";
$client_secret = "YOUR_CLIENT_SECRET";

$url = "https://naveropenapi.apigw.ntruss.com/datalab/v1/search";
$body = "{\"startDate\":\"2017-01-01\",\"endDate\":\"2017-04-30\",\"timeUnit\":\"month\",\"keywordGroups\":[{\"groupName\":\"Korean\",\"keywords\":[\"Korean\",\"korean\"]},{\"groupName\":\"English\",\"keywords\":[\"English\",\"english\"]}],\"device\":\"pc\",\"ages\":[\"1\",\"2\"],\"gender\":\"f\"}";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$headers = array();
$headers[] = "X-NCP-APIGW-API-KEY-ID: ".$client_id;
