来自URL文本文件的Java单行扫描程序

Question

在java中，我需要从“http://www.mysite.com/text.txt”获取什么代码到扫描程序，该扫描程序尽可能少地解析网站中包含的结果文本。

Answer 1

Scanner sc = new Scanner(new URL("http://www.mysite.com/text.txt").openStream());

Answer 2

URL yahoo = new URL("http://www.yahoo.com/");
    BufferedReader in = new BufferedReader(
                new InputStreamReader(
                yahoo.openStream()));

    String inputLine;

    while ((inputLine = in.readLine()) != null)
        System.out.println(inputLine);

    in.close();

URLConnection connection = new URL("http://www.mysite.com/text.txt").openConnection();
String text = new Scanner(connection.getInputStream()).useDelimiter("\\Z").next();

在一行代码中

一个HTTP GET ：（使用Java 8）

String doc = new Scanner(new URL(strUrl).openStream(), "UTF-8").useDelimiter("\\A").next();
