无法使用JAVA从网站提取xml数据

出了什么问题

如果运行以下代码，您将看到返回的数据不是XML，而是JSON。

import java.net.URL;import java.io.InputStream;public class Demo {    public static void main(String[] args) throws Exception {        URL url = new URL("https://api.eancdn.com/ean-services/rs/hotel/v3/list?apiKey=vkndmgahz5aekd65pxg4rvvp&locale=en_US&currencyCode=USD&latitude=51.514&longitude=-0.269");        InputStream is = url.openStream();        int next = is.read();        while(next != -1) { System.out.print((char) next); next = is.read();        }    }}

以XML形式获取数据

您可以使用

HttpURLConnection

import java.net.HttpURLConnection;import java.net.URL;import java.io.InputStream;import javax.xml.parsers.*;import org.w3c.dom.document;public class Demo {    public static void main(String[] args) throws Exception {        URL url = new URL("https://api.eancdn.com/ean-services/rs/hotel/v3/list?apiKey=vkndmgahz5aekd65pxg4rvvp&locale=en_US&currencyCode=USD&latitude=51.514&longitude=-0.269");        HttpURLConnection connection = (HttpURLConnection) url.openConnection();        connection.setRequestMethod("GET");        connection.setRequestProperty("Accept", "application/xml");        InputStream is = connection.getInputStream();        documentBuilderFactory dbf = documentBuilderFactory.newInstance();        documentBuilder db = dbf.newdocumentBuilder();        document doc = db.parse(is);    }}
