从 URL 获取文件 - 错误

Question

感谢这个问题(link)，我知道了如何从互联网上下载文件。但是，我得到的不是 txt 文件中的普通文本，而是 html 响应。有谁知道我做错了什么？

这是我的代码：

                    // Install Authenticator
                MyAuthenticator.setPasswordAuthentication("Username", "Password");
                Authenticator.setDefault (new MyAuthenticator(Main.getPropertyPath()));

                URL website = new URL("http://.../5-Anhang.txt?revision=1260");
                ReadableByteChannel rbc = Channels.newChannel(website.openStream());
                FileOutputStream fos = new FileOutputStream("information.txt");
                fos.getChannel().transferFrom(rbc, 0, Long.MAX_VALUE);

Answer 1

看来我可能会在网页上搜索 class "revision=1260" 并返回

Answer 2

由于评论不可读，发布答案。

import java.io.*;
import java.net.*;

public class App {
    public static void main(String[] args) throws Exception{

      URL url = new URL("http://localhost:8080/js/txt1.txt");
        // read text
        BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
    String line;
        while ((line = in.readLine()) != null) {
        System.out.println(line);
    }
    in.close();
    }
}

以下代码用于读取以下格式的文本文件

Novak Djokovic
Andy Murray
Roger Federer
Nishokiri

输出

Novak Djokovic

Andy Murray

Roger Federer

Nishokiri
