如何使用JAVA从REST API调用中打印/读取图像

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;

import javax.imageio.ImageIO;
import java.awt.image.BufferedImage;
import java.io.ByteArrayInputStream;
import java.io.File;
import java.io.IOException;

public class ImageApiCaller {
    public static void main(String[] args) {
        String apiUrl = "https://example.com/api/image"; // 替换为实际的API URL

        HttpClient httpClient = HttpClientBuilder.create().build();
        HttpGet httpGet = new HttpGet(apiUrl);

        try {
            HttpResponse response = httpClient.execute(httpGet);
            HttpEntity entity = response.getEntity();

            if (entity != null) {
                byte[] imageBytes = EntityUtils.toByteArray(entity);
                ByteArrayInputStream bis = new ByteArrayInputStream(imageBytes);
                BufferedImage image = ImageIO.read(bis);

                // 打印图像
                ImageIO.write(image, "png", new File("image.png"));

                // 读取图像
                BufferedImage readImage = ImageIO.read(new File("image.png"));
                // 进一步处理图像...

                bis.close();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
