java - WSDL SOAP Webservice Java 客户端的错误 415

问题描述

这次我需要一些帮助来解决我找不到问题所在的错误。

我开发了一个非常简单的 Java 代码来使用 Web 服务，但是当我运行它时，我得到了这个讨厌的错误：“原因：java.io.IOException：服务器返回 HTTP 响应代码：415 用于 URL：http://www .dataaccess.com/webservicesserver/numberconversion.wso/NumberToWords"

调查此错误时，它说这与不支持 Content-Type 有关，因此下载了 SoapUI 5.6.0 以查看 WS 正在等待什么，这对我来说似乎是正确的。

这是我的代码：

package principal;

import java.io.BufferedReader;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.StringReader;

import org.xml.sax.SAXException;

public class PruebaWS {
    public void getNumber(int number){
        String wsURL = "http://www.dataaccess.com/webservicesserver/numberconversion.wso/NumberToWords";
        URL url = null;
        URLConnection connection = null;
        HttpURLConnection httpConn = null;
        String responseString = null;
        String outputString = null;
        ByteArrayOutputStream bout = null;
        OutputStream out = null;
        InputStreamReader isr = null;
        BufferedReader in = null;
        
        String xmlInput = 
                "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:web=\"http://www.dataaccess.com/webservicesserver/\">" +
                "   <soapenv:Header/>" +
                "   <soapenv:Body>" +
                "      <web:NumberToWords>" +
                "         <web:ubiNum>" + number +"</web:ubiNum>" +
                "      </web:NumberToWords>" +
                "   </soapenv:Body>" +
                "</soapenv:Envelope>";
        
        try {
            url = new URL(wsURL);
            connection = url.openConnection();
            httpConn = (HttpURLConnection) connection;
            
            byte[] buffer = new byte[xmlInput.length()];
            buffer = xmlInput.getBytes();
            
            String SOAPAction = "";
            httpConn.setRequestMethod("POST");
            httpConn.setRequestProperty("SOAPAction", SOAPAction);
            httpConn.setRequestProperty("Content-Length", String.valueOf(buffer.length));
            httpConn.setRequestProperty("Content-Type", "text/xml;charset=utf-8");
            httpConn.setRequestProperty("Accept", "*/xml");
            httpConn.setDoInput(true);
            httpConn.setDoOutput(true);
            httpConn.setUseCaches(false);
            
            out = httpConn.getOutputStream();
            out.write(buffer);
            out.close();
            
            // Lee la respuesta y escribe a un output estándard
            isr = new InputStreamReader(httpConn.getInputStream());
            in = new BufferedReader(isr);
            
            while ((responseString = in.readLine()) != null)
                outputString = outputString + responseString;
            
            System.out.println(outputString);
            System.out.println("");
            
            // Obtiene la respuesta desde la llamada al webService
            Document document = parseXmlFile(outputString);
            
            NodeList nodeList = document.getElementsByTagName("m:NumberToWordsResponse");
            String webServiceResponse = nodeList.item(0).getTextContent();
            System.out.println("La respuesta del web service es: " + webServiceResponse);
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
    }
    
    private Document parseXmlFile(String in){
        try {
            DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
            DocumentBuilder db = dbf.newDocumentBuilder();
            InputSource is = new InputSource(new StringReader(in));
            return db.parse(is);
        } catch (ParserConfigurationException | SAXException | IOException e) {
            throw new RuntimeException(e);
        }
    }
}

这是运行时的错误：

线程“主”java.lang.RuntimeException 中的异常：java.io.IOException：服务器返回 HTTP 响应代码：415 用于 URL： http ://www.dataaccess.com/webservicesserver/numberconversion.wso/NumberToWords 在 principal.PruebaWS。 getNumber(PruebaWS.java:83) at principal.Main.main(Main.java:6) 原因：java.io.IOException：服务器返回 HTTP 响应代码：415 用于 URL： http ://www.dataaccess.com/ webservicesserver/numberconversion.wso/NumberToWords 在 java.base/sun.net.www.protocol.http.HttpURLConnection.getInputStream0(HttpURLConnection.java:1919) 在 java.base/sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1515)在 principal.PruebaWS.getNumber(PruebaWS.java:67) ... 1 more C:\Local\NetBeans\Cache\11.1\executor-snippets\run.xml:111：执行此行时出现以下错误：C： \Local\NetBeans\Cache\11.1\executor-snippets\run.xml:68：Java 返回：1 BUILD FAILED（总时间：2 秒）

任何帮助都是有价值的。
