从网站到字符串的结果

Question

如何将网站结果（例如https://blockchain.info/de/q/24hrprice）转换为字符串/整数？我是否必须从网站上阅读源代码？

我正在使用Android Studio进行开发。

Answer 1

BufferedReader in = null;
try {
  String urlStr = "https://blockchain.info/de/q/24hrprice";
  URL url = new URL(urlStr);
  URLConnection con = url.openConnection();
  in = new BufferedReader(new InputStreamReader(con.getInputStream(), "UTF-8"));
  String input;
  while ((input = in.readLine()) != null) {
    System.out.println(input); //you can parse input as Integer or Double now
  }

} catch (MalformedURLException ex) {
  System.err.println(ex);
} catch (IOException ex) {
  System.err.println(ex);
} finally {
  try {
    in.close();
  } catch (Exception ex) {
    System.err.println(ex);
  }
}
