我需要手动访问 .Net SOAP 服务。所有的进口商都有它的 WSDL 问题，所以我只是手动创建 XML 消息，使用 HttpURLConnection 连接，然后解析结果。我已经将 Http/SOAP 调用包装到一个函数中，该函数应该将结果作为字符串返回。这是我所拥有的：

  //passed in values: urlAddress, soapAction, soapDocument

  URL u = new URL(urlAddress);
  URLConnection uc = u.openConnection();
  HttpURLConnection connection = (HttpURLConnection) uc;

  connection.setDoOutput(true);
  connection.setDoInput(true);
  connection.setRequestMethod("POST");
  connection.setRequestProperty("SOAPAction", soapAction);
  connection.setRequestProperty("User-Agent","Mozilla/5.0 ( compatible ) ");
  connection.setRequestProperty("Accept","[star]/[star]");      
  connection.setRequestProperty("Content-Type", "text/xml; charset=utf-8");

  OutputStream out = connection.getOutputStream();
  Writer wout = new OutputStreamWriter(out);

  //helper function that gets a string from a dom Document
  String xmldata = XmlUtils.GetDocumentXml(soapDocument);
  wout.write(xmldata);        
  wout.flush();
  wout.close();

  // Response
  int responseCode = connection.getResponseCode();
  BufferedReader rd = new BufferedReader(new InputStreamReader(connection.getInputStream()));
  String responseString = "";
  String outputString = "";
  //Write the SOAP message response to a String.
  while ((responseString = rd.readLine()) != null) {
      outputString = outputString + responseString;
  }

  return outputString;

我的问题是BufferedReader rd = new BufferedReader(new InputStreamReader(connection.getInputStream()));我得到一个带有我正在使用的地址的“java.io.FileNotFoundException”（即urlAddress）。如果我将该地址粘贴到浏览器中，它会很好地打开 Soap 服务网页（地址是http://protectpaytest.propay.com/API/SPS.svc）。根据我的阅读，FileNotFoundException 是 HttpURLConnection 返回 400+ 错误消息。我添加了行 getResponseCode() 只是为了查看确切的代码是什么，它是 404。我从其他一些页面添加了 User-Agent 和 Accept 标头，说它们是必需的，但我仍然得到 404。

我还缺少其他标题吗？我还需要做什么才能让这个调用工作（因为它在浏览器中工作）？
