如何使用Httpclient上传图片？

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.ContentType;
import org.apache.http.entity.mime.MultipartEntityBuilder;
import org.apache.http.entity.mime.content.FileBody;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;

import java.io.File;
import java.io.IOException;

public class ImageUploader {
    public static void main(String[] args) {
        String url = "http://example.com/upload"; // 上传图片的URL
        String filePath = "/path/to/image.jpg"; // 图片文件路径

        HttpClient httpClient = HttpClientBuilder.create().build();
        HttpPost httpPost = new HttpPost(url);

        // 创建多部分实体
        MultipartEntityBuilder builder = MultipartEntityBuilder.create();
        // 添加图片文件参数
        FileBody fileBody = new FileBody(new File(filePath), ContentType.DEFAULT_BINARY);
        builder.addPart("image", fileBody);

        // 设置请求实体
        HttpEntity entity = builder.build();
        httpPost.setEntity(entity);

        try {
            // 执行请求并获取响应
            HttpResponse response = httpClient.execute(httpPost);
            HttpEntity responseEntity = response.getEntity();

            // 处理响应结果
            if (responseEntity != null) {
                String result = EntityUtils.toString(responseEntity);
                System.out.println("上传结果：" + result);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
