Java experts will take you to practice: practical skills for docking Baidu AI interface

Introduction:
With the rapid development of artificial intelligence, Baidu AI interface has become an important tool for development One of the popular choices among readers. By connecting to Baidu AI interface, we can easily implement various artificial intelligence functions, such as speech recognition, image recognition, natural language processing, etc. This article will take you through actual combat, use Java language to connect Baidu AI interface, and give some practical tips and code examples.

1. Preparation
Before starting, we need to apply for the key (AK/SK) of Baidu AI interface, and download and introduce the corresponding Java SDK. Baidu AI interface provides detailed documentation and sample code. We can refer to the official documentation for development.

2. Text recognition
The text recognition function in Baidu AI interface is very practical. It can extract text from pictures to facilitate subsequent processing and analysis. The following is a sample code for text recognition:

import com.baidu.aip.ocr.AipOcr;
import org.json.JSONObject;

public class OCRDemo {
    // 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) {
        // 初始化客户端
        AipOcr client = new AipOcr(APP_ID, API_KEY, SECRET_KEY);

        // 读取图片文件
        String filePath = "your_image_path";
        byte[] image = ImageUtil.readFile(filePath);

        // 调用API进行文字识别
        JSONObject res = client.basicGeneral(image, new HashMap<>());

        // 处理结果
        JSONArray wordsResult = res.getJSONArray("words_result");
        for (int i = 0; i < wordsResult.length(); i++) {
            JSONObject words = wordsResult.getJSONObject(i);
            System.out.println(words.getString("words"));
        }
    }
}

3. Speech recognition
Baidu AI interface also provides a powerful speech recognition function that can convert speech files into text. The following is a sample code for speech recognition:

import com.baidu.aip.speech.AipSpeech;
import org.json.JSONObject;

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;

public class SpeechRecognitionDemo {
    // 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) throws IOException {
        // 初始化客户端
        AipSpeech client = new AipSpeech(APP_ID, API_KEY, SECRET_KEY);

        // 读取语音文件
        String filePath = "your_audio_path";
        byte[] audio = Files.readAllBytes(Paths.get(filePath));

        // 调用API进行语音识别
        JSONObject res = client.asr(audio, "pcm", 16000, null);

        // 处理结果
        System.out.println(res.toString());
    }
}

4. Image recognition
Image recognition is one of the core functions of Baidu AI interface, which can identify objects, scenes, text and other information in pictures. The following is a sample code for image recognition:

import com.baidu.aip.imageclassify.AipImageClassify;
import org.json.JSONObject;

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.HashMap;

public class ImageRecognitionDemo {
    // 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) throws IOException {
        // 初始化客户端
        AipImageClassify client = new AipImageClassify(APP_ID, API_KEY, SECRET_KEY);

        // 读取图片文件
        String filePath = "your_image_path";
        byte[] image = Files.readAllBytes(Paths.get(filePath));

        // 调用API进行图像识别
        JSONObject res = client.advancedGeneral(image, new HashMap<>());

        // 处理结果
        System.out.println(res.toString());
    }
}

5. Natural language processing
Natural language processing is another important function of Baidu AI interface, which can realize sentiment analysis, keyword extraction, text classification and other functions. . The following is a sample code for natural language processing:

import com.baidu.aip.nlp.AipNlp;
import org.json.JSONObject;

public class NLPDemo {
    // 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) {
        // 初始化客户端
        AipNlp client = new AipNlp(APP_ID, API_KEY, SECRET_KEY);

        // 调用API进行自然语言处理
        String text = "你好，百度";
        JSONObject res = client.sentimentClassify(text, new HashMap<>());

        // 处理结果
        System.out.println(res.toString());
    }
}

6. Summary
