向网络服务发送 XML 请求

Question

我正在尝试将包含 xml 数据的调用发送到特定的 Web 服务，但收到响应代码 500。我正在努力解决此问题。任何意见将不胜感激。

String wsURL =  "https://wd2-impl-services1.workday.com/ccx/service/Payteam/v10.2?wsdl";

URL url = null;

URLConnection 连接= null;

HttpURLConnection httpConn = null;

字符串responseString = null;

字符串outputString =“”;

OutputStream out = null;

InputStreamReader isr = null;

BufferedReader in = null;``

String xmlInput =

“XML文档”

try

url = new URL(wsURL);

connection = url.openConnection();

httpConn = (HttpURLConnection) 连接;`

byte[] buffer = new byte[xmlInput.length()];``

缓冲区 = xmlInput.getBytes();`

String SOAPAction = "";

//设置相应的HTTP参数\属性。

httpConn.setRequestProperty("Content-Length", String.valueOf(buffer.length));

httpConn .setRequestProperty("Content-Type","text/xml; charset-utf-8");

httpConn.setRequestProperty("用户名","用户名");

httpConn.setRequestProperty("密码", "密码”）；`

httpConn.setRequestProperty("SOAPAction",SOAPAction);

httpConn.setRequestMethod("POST");

httpConn.setDoOutput(true);

httpConn.setDoInput(true);

out = httpConn.getOutputStream();

out.write(buffer);

out.close();

//Read Response

isr = new InputStreamReader(httpConn.getInputStream());

in = new BufferedReader(isr);

while ((responseString = in.readLine())  != null)

outputString = outputString + responseString;

System.out.println(outputString);

System.out.println("");

Document document = parseXmlFile(outputString);

}``

catch（异常e）

e.printStackTrace();

}`

private static 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 e) {

throw new RuntimeException(e);

}   catch (SAXException e) {

throw new RuntimeException(e);

}   catch (IOException e) {

throw new RuntimeException(e);

您需要使用 JAXB 根据上面链接到的 wsdl 文件生成客户端。然后使用所述客户端与 SOAP Web 服务进行通信。

这已经在网上描述了一百万次，所以我将在这里链接到一个很好的解释：
