JAVA实现 图片或文件下载功能示例代码

import java.io.FileOutputStream;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;

public class TestDownload {

	public static void main(String args[]) throws Exception {
		TestDownload.getImagesNew("https://zszhan.cn/upload/image/20210630/zip/183904.png", "D:\\temp\\a.png");
	}

	/**
	 * @param urlPath 图片路径
	 * @throws Exception
	 */
	public static void getImagesNew(String urlPath, String fileName) throws Exception {
		URL url = new URL(urlPath);// ：获取的路径
		// :http协议连接对象
		HttpURLConnection conn = (HttpURLConnection) url.openConnection();
		conn.setRequestMethod("GET");
		conn.setReadTimeout(6 * 10000);
		if (conn.getResponseCode() < 10000) {
			InputStream inputStream = conn.getInputStream();
			FileOutputStream outputStream = new FileOutputStream(fileName);

			byte[] buffer = new byte[2048];
			int len = -1;
			while ((len = inputStream.read(buffer)) != -1) {
				outputStream.write(buffer, 0, len);
			}

			outputStream.close();
			inputStream.close();
			System.out.println(1111);
		}
