Test translation

This section describes a text translation example.

Java

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

import java.io.BufferedReader;
import java.io.DataOutputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLEncoder;
public class APIExamTranslate {

    public static void main(String[] args) {
        String clientId = "YOUR_CLIENT_ID";//Application's client ID value";
        String clientSecret = "YOUR_CLIENT_SECRET";//Application's client secret value";
        try {
            String text = URLEncoder.encode("Nice to meet you.", "UTF-8");
            String apiURL = "https://naveropenapi.apigw.ntruss.com/nmt/v1/translation";
            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);
            // post request
            String postParams = "source=ko&target=en&text=" + text;
            con.setDoOutput(true);
            DataOutputStream wr = new DataOutputStream(con.getOutputStream());
            wr.writeBytes(postParams);
            wr.flush();
            wr.close();
            int responseCode = con.getResponseCode();
            BufferedReader br;
            if(responseCode==200) { // Successful call
                br = new BufferedReader(new InputStreamReader(con.getInputStream()));
            } else {  // Error occurred
                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 API.

import os
import sys
import urllib.request
client_id = "YOUR_CLIENT_ID"
client_secret = "YOUR_CLIENT_SECRET"
encText = urllib.parse.quote("Enter a sentence to translate")
data = "source=ko&target=en&text=" + encText
url = "https://naveropenapi.apigw.ntruss.com/nmt/v1/translation"
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)
response = urllib.request.urlopen(request, data=data.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 API.

<?php
  $client_id = "YOUR_CLIENT_ID";
  $client_secret = "YOUR_CLIENT_SECRET";
  $encText = urlencode("Nice to meet you.");
  $postvars = "source=ko&target=en&text=".$encText;
  $url = "https://naveropenapi.apigw.ntruss.com/nmt/v1/translation";
  $is_post = true;
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_POST, $is_post);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
  curl_setopt($ch,CURLOPT_POSTFIELDS, $postvars);
  $headers = array();
  $headers[] = "X-NCP-APIGW-API-KEY-ID: ".$client_id;
  $headers[] = "X-NCP-APIGW-API-KEY: ".$client_secret;
  curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
  $response = curl_exec ($ch);
  $status_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
  echo "status_code:".$status_code."<br />";
  curl_close ($ch);
  if($status_code == 200) {
    echo $response;
  } else {
    echo "Error content:".$response;
  }
?>

JavaScript

The following is a JavaScript-based sample code for the API.

var express = require('express');
var app = express();
var client_id = 'YOUR_CLIENT_ID';
var client_secret = 'YOUR_CLIENT_SECRET';
var query = 'Enter a sentence to translate.';
app.get('/translate', function(req, res) {
  var api_url = 'https://naveropenapi.apigw.ntruss.com/nmt/v1/translation';
  var request = require('request');
  var options = {
    url: api_url,
    form: { source: 'ko', target: 'en', text: query },
    headers: { 'X-NCP-APIGW-API-KEY-ID': client_id, 'X-NCP-APIGW-API-KEY': client_secret },
  };
  request.post(options, function(error, response, body) {
    if (!error && response.statusCode == 200) {
      res.writeHead(200, { 'Content-Type': 'text/json;charset=utf-8' });
      res.end(body);
    } else {
      res.status(response.statusCode).end();
      console.log('error = ' + response.statusCode);
    }
  });
});
app.listen(3000, function() {
  console.log('http://127.0.0.1:3000/translate app listening on port 3000!');
});

C#

using System;
using System.Net;
using System.Text;
using System.IO;

namespace NaverAPI_Guide
{
    public class APIExamTranslate
    {
        static void Main(string[] args)
        {
            string url = "https://naveropenapi.apigw.ntruss.com/nmt/v1/translation";
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
            request.Headers.Add("X-NCP-APIGW-API-KEY-ID", "YOUR-CLIENT-ID");
            request.Headers.Add("X-NCP-APIGW-API-KEY", "YOUR-CLIENT-SECRET");
            request.Method = "POST";
            string query = "How's the weather today?";
            byte[] byteDataParams = Encoding.UTF8.GetBytes("source=ko&target=en&text=" + query);
            request.ContentType = "application/x-www-form-urlencoded";
            request.ContentLength = byteDataParams.Length;
            Stream st = request.GetRequestStream();
            st.Write(byteDataParams, 0, byteDataParams.Length);
            st.Close();
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            Stream stream = response.GetResponseStream();
            StreamReader reader = new StreamReader(stream, Encoding.UTF8);
            string text = reader.ReadToEnd();
            stream.Close();
            response.Close();
            reader.Close();
            Console.WriteLine(text);
        }
    }
}

Apply substitution option

This section describes examples of applying the substitution option.

Java

The following is a sample code based on Java using replaceInfo.

Indexes 0 – 3 are source text copy, 5 – 8 are designated as test.
replaceInfo={"infos":[{"begin":0,"length":4},{"begin":5,"length":4,"str":"test"}]}

HTML

The following is a sample code based on HTML using the HTML <span> tag.

I love <span translate="no">#BTS</span>
