如何使用HttpClient将文件上传到Ubuntu的特定路径

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.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;

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

public class FileUploader {
    public static void main(String[] args) {
        String filePath = "path/to/file"; // 要上传的文件路径
        String uploadUrl = "http://ubuntu-server/upload"; // 上传文件的URL

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

        File file = new File(filePath);
        MultipartEntityBuilder builder = MultipartEntityBuilder.create();
        builder.addBinaryBody("file", file, ContentType.DEFAULT_BINARY, file.getName());

        HttpEntity multipart = builder.build();
        httpPost.setEntity(multipart);

        try {
            HttpResponse response = httpClient.execute(httpPost);
            int statusCode = response.getStatusLine().getStatusCode();
            if (statusCode == 200) {
                String responseBody = EntityUtils.toString(response.getEntity());
                System.out.println("文件上传成功：" + responseBody);
            } else {
                System.out.println("文件上传失败，错误码：" + statusCode);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
