java - 使用 Java 从文本/字符串中获取特定 URL

Question

我是 Java 新手，我想获取下面文本中的所有 URL

WEBSITE1 https://localhost:8080/admin/index.php?page=home
WEBSITE2 https://192.168.0.3:8084/index.php
WEBSITE3 https://192.168.0.5:9090/controller/index.php?page=home
WEBSITE4 https://192.168.0.1:8080/home/index.php?page=forum

我想要的结果是:

https://localhost:8080
https://192.168.0.3:8084
https://192.168.0.5
https://192.168.0.1:8080

我也想将它存储到链接列表或数组中。有人可以教我吗？谢谢您

这就是你可以做到这一点的方法。我为你做了一个，剩下的你做:)

try {
            ArrayList<String> urls = new ArrayList<String>();
            URL aURL = new URL("https://localhost:8080/admin/index.php?page=home");
             System.out.println("protocol = " + aURL.getProtocol()+aURL.getHost()+aURL.getPort());
             urls.add(aURL.getProtocol()+aURL.getHost()+aURL.getPort());
        } catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
