Java Baidu Translation API realizes the practice of mutual translation between Chinese and Polish

Introduction:
With the rapid development of globalization, the exchanges between people have gradually increased. Language has become one of the biggest barriers between different countries. However, with the development of artificial intelligence and machine learning, translation technology has been greatly improved, making it easier for people to overcome language barriers. This article will introduce how to use the Java programming language and Baidu Translation API to achieve mutual translation between Chinese and Polish.

Preparation work:
First, we need to register and create an application for Baidu Translation API, and obtain the API Key and Secret Key. This process has detailed step-by-step instructions on the official website of Baidu Translation API.

Step 1: Reference the required libraries
First, introduce the HttpClient and FastJson libraries into the Java project for sending HTTP requests and processing JSON data.

import org.apache.http.HttpEntity;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONArray;
import com.alibaba.fastjson.JSONException;
import com.alibaba.fastjson.JSONObject;

Step 2: Construct an HTTP request
Next, we need to generate an HTTP POST request object and set the request header and request body.

String url = "https://fanyi-api.baidu.com/api/trans/vip/translate";
String appId = "YOUR_APP_ID";
String appKey = "YOUR_APP_KEY";
String payload = "{"q":"你好","from":"auto","to":"pl","appid":"" + appId +
"","salt":"1435660288","sign":"" + getSign("你好", "1435660288", appKey) + ""}";

CloseableHttpClient httpClient = HttpClients.createDefault();
HttpPost httpPost = new HttpPost(url);
httpPost.addHeader("Content-Type", "application/json; charset=utf-8");
httpPost.setEntity(new StringEntity(payload, "utf-8"));

Among them, the getSign() method is used to generate signatures. The rules for signature generation can be found in the official documentation of Baidu Translation API.

Step 3: Send HTTP request
Send HTTP request and get the response result.

CloseableHttpResponse response = httpClient.execute(httpPost);
HttpEntity entity = response.getEntity();
String result = EntityUtils.toString(entity, "utf-8");

Step 4: Parse JSON data
Parse the obtained JSON data into Java objects and extract the required translation results.

try {
    JSONObject jsonObject = JSON.parseObject(result);
    JSONArray transResult = jsonObject.getJSONArray("trans_result");
    JSONObject resultObj = transResult.getJSONObject(0);
    String translatedText = resultObj.getString("dst");
    System.out.println(translatedText);
} catch (JSONException e) {
    e.printStackTrace();
}

At this point, we have completed the translation operation from Chinese to Polish. If you need to translate other languages ​​into each other, just modify the relevant parameters.

Summary:
Through the mutual translation of Chinese and Polish through the Java programming language and Baidu Translation API, we can see the convenience of translation technology. This technology has a wide range of applications, whether it is business communication or cultural communication, it can help people better understand and communicate. Of course, translation technology also has certain limitations, such as the handling of terminology and cultural differences in specific fields. But with the advancement of technology, we believe that translation technology will continue to improve and provide better support for us to overcome language barriers.
