Java语言怎么将一个文件复制到网站上

import java.io.*;
import java.net.URL;
import java.net.HttpURLConnection;

public class FileUploader {
    public static void copyFileToWebsite(String filePath, String websiteUrl) {
        try {
            // 创建URL对象
            URL url = new URL(websiteUrl);

            // 打开连接
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();

            // 设置请求方法为POST
            connection.setRequestMethod("POST");

            // 允许输入输出流
            connection.setDoInput(true);
            connection.setDoOutput(true);

            // 获取输出流
            OutputStream outputStream = connection.getOutputStream();

            // 创建文件输入流
            File inputFile = new File(filePath);
            FileInputStream fileInputStream = new FileInputStream(inputFile);

            // 创建缓冲区
            byte[] buffer = new byte[1024];
            int bytesRead;

            // 从文件输入流读取数据，并写入输出流
            while ((bytesRead = fileInputStream.read(buffer)) != -1) {
                outputStream.write(buffer, 0, bytesRead);
            }

            // 关闭输入流和输出流
            fileInputStream.close();
            outputStream.close();

            // 获取响应码
            int responseCode = connection.getResponseCode();

            if (responseCode == HttpURLConnection.HTTP_OK) {
                // 文件复制成功
                System.out.println("文件复制成功");
            } else {
                // 文件复制失败
                System.out.println("文件复制失败");
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        String filePath = "path/to/input/file";
        String websiteUrl = "http://example.com/upload";

        copyFileToWebsite(filePath, websiteUrl);
    }
}
