服务器返回的HTTP响应代码：URL的415（java / xml）

Question

我连接到url（xml）文件并创建Java对象时遇到问题。 到目前为止，由于“服务器返回的HTTP响应代码：URL 415”，我无法连接到我的链接

我的链接： http : //services.odata.org/V3/Northwind/Northwind.svc/Employees

我的代码（不完整，但是异常抛出在那里）：

 package logic;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLConnection;

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;

import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
import org.xml.sax.SAXException;

public class XMLReader {

    public static void main(String[] args) throws IOException, ParserConfigurationException, SAXException {
        //JsonObject requestJson = new JsonObject();
        String url = "http://services.odata.org/V3/Northwind/Northwind.svc/Employees";
        URL myurl = new URL(url);
        HttpURLConnection con = (HttpURLConnection)myurl.openConnection();
        con.setDoOutput(true);
        con.setDoInput(true);

        con.setRequestProperty("Content-Type", "application/xml; charset=utf-8");
        con.setRequestProperty("Accept", "application/xml");
        con.setRequestProperty("Method", "GET");

        InputStream xml = con.getInputStream();

        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        DocumentBuilder db = dbf.newDocumentBuilder();
        Document doc = db.parse(xml);

        doc.getDocumentElement().normalize();
}

Answer 1

使con.setRequestProperty（“ Accept”，“ application / xml”）; 到con.setRequestProperty（“ Accept”，“ * / xml”）;
