Practical exploration of Java Baidu Translation API to realize mutual translation between Chinese and Czech

Introduction: With the development of globalization, exchanges and cooperation between different countries have become increasingly frequent. Language is an important tool for people to communicate, so language translation services have become particularly important. Baidu Translation API is an open platform based on machine translation, providing multi-lingual translation services. This article will use Java programming language to realize practical exploration of mutual translation between Chinese and Czech by calling Baidu Translation API.

1. Obtain the application ID and key of Baidu Translation API

Before using Baidu Translation API, we first need to apply for an application on Baidu Translation Open Platform and obtain the application ID and key key. The specific steps are as follows:

1. Visit Baidu Translation Open Platform (http://api.fanyi.baidu.com/), register a developer account, log in and enter the "My Application" page.

2. Click "Create Application", fill in the application name and description and other relevant information, and click OK to complete the creation.

3. On the "My Application" page, find the application you just created and click "API Information" to get the application ID and key.

2. Add dependencies on Baidu Translation API

To use Baidu Translation API in a Java project, we need to add the corresponding dependencies first. In the project's pom.xml file, add the following dependencies:

<dependency>
    <groupId>com.baidu.aip</groupId>
    <artifactId>java-sdk</artifactId>
    <version>4.7.0</version>
</dependency>

3. Implement Chinese translation into Czech

Below we use a simple example to demonstrate how to achieve Chinese translation into Czech . First, we need to write a Java class named BaiduTranslator, the code is as follows:

import com.baidu.aip.translation.AipTranslation;
import org.json.JSONObject;

public class BaiduTranslator {
    // 设置APPID/AK/SK
    public static final String APP_ID = "your_app_id";
    public static final String API_KEY = "your_api_key";
    public static final String SECRET_KEY = "your_secret_key";

    public static void main(String[] args) {
        // 初始化一个AipTranslation
        AipTranslation client = new AipTranslation(APP_ID, API_KEY, SECRET_KEY);

        // 设置可选参数
        JSONObject options = new JSONObject();
        options.put("from", "zh");
        options.put("to", "cs");

        // 翻译中文文本
        String text = "你好，世界";
        JSONObject result = client.translate(text, options);

        // 输出翻译结果
        System.out.println(result.toString(2));
    }
}

In this class, we first set the application ID and key of Baidu Translator API. Then, we initialize an AipTranslation object and set the source language of the translation to Chinese ("zh") and the target language to Czech ("cs"). Next, we call the translate method, passing in the Chinese text to be translated and optional parameters for translation. Finally, we output the translation results.

Run this program and you will get the following output:

{
  "error_code": 0,
  "error_msg": "SUCCESS",
  "from": "zh",
  "to": "cs",
  "trans_result": [
    {
      "dst": "Ahoj, světe"
    }
  ]
}

As can be seen from the output, the input Chinese text "Hello, World" is translated into Czech "Ahoy, svete".

4. Translate Czech to Chinese

Let’s translate Czech to Chinese. We only need to make simple modifications to the above code and set the source language and target language to Czech and Chinese. The modified code is as follows:

import com.baidu.aip.translation.AipTranslation;
import org.json.JSONObject;

public class BaiduTranslator {
    // 设置APPID/AK/SK
    public static final String APP_ID = "your_app_id";
    public static final String API_KEY = "your_api_key";
    public static final String SECRET_KEY = "your_secret_key";

    public static void main(String[] args) {
        // 初始化一个AipTranslation
        AipTranslation client = new AipTranslation(APP_ID, API_KEY, SECRET_KEY);

        // 设置可选参数
        JSONObject options = new JSONObject();
        options.put("from", "cs");
        options.put("to", "zh");

        // 翻译捷克语文本
        String text = "Ahoj, svete";
        JSONObject result = client.translate(text, options);

        // 输出翻译结果
        System.out.println(result.toString(2));
    }
}

Similarly, running the program will get the following output Result:

{
  "error_code": 0,
  "error_msg": "SUCCESS",
  "from": "cs",
  "to": "zh",
  "trans_result": [
    {
      "dst": "你好，世界"
    }
  ]
}

As can be seen from the output result, the input Czech text "Ahoj, svete" is translated into Chinese "Hello, world".

Summary:

This article uses the Java programming language to achieve mutual translation between Chinese and Czech by calling Baidu Translation API. Through simple code examples, we can see the ease of use and accuracy of Baidu Translation API. I hope this article will be helpful to developers who want to use Baidu Translation API for language translation.
