如何在java.net.URLConnection上指定本地地址？

// 打开网络连接并指定本地文件路径
URL url = new URL("file:///path/to/your/local/file.txt");
URLConnection connection = url.openConnection();

// 获取资源输入流并读取文件内容
InputStream is = connection.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
String line;
StringBuilder content = new StringBuilder();

while ((line = reader.readLine()) != null) {
    content.append(line);
}

// 关闭输入流
reader.close();
