SOAP 信封响应错误：读取 XMLStreamReader 时出错

Question

我在下面有以下 Android 应用代码。我正在尝试通过 HTTP 连接到 Web 服务。 Web 服务使用 apache 轴。但是，我在响应中遇到了错误“读取 XMLStreamReader 时出错”。我真的被困住了，不知道我能做什么。会不会是服务器端和客户端使用了不同版本的 HTTP 客户端和 SOAP？对此的任何帮助将不胜感激。 Web 服务非常简单：sayHello 方法显示 arg0=some_string 中给出的参数

public class MainActivity extends Activity {
@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
    StrictMode.setThreadPolicy(policy);

    BufferedReader in = null;
    try {
        HttpClient client = new DefaultHttpClient();
        HttpPost request = new HttpPost(
                "http://10.0.0.63:8080/archibus/cxf/HelloWorld/sayHello");
        request.addHeader("Content-Type", "text/xml");
        List<NameValuePair> postParameters = new ArrayList<NameValuePair>();
        postParameters.add(new BasicNameValuePair("arg0", "testing"));
        UrlEncodedFormEntity formEntity = new UrlEncodedFormEntity(postParameters);
        request.setEntity(formEntity);

        HttpResponse response = client.execute(request);

        in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
        StringBuffer sb = new StringBuffer("");
        String line = "";
        String NL = System.getProperty("line.separator");
        while ((line = in.readLine()) != null) {
            sb.append(line + NL);
        }
        in.close();

        String page = sb.toString();
        // Log.i(tag, page);
        System.out.println(page);
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        if (in != null) {
            try {
                in.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}
}

您的 WebService 请求构造不正确。您实际上是在创建表单请求，而不是实际的 SOAP 请求。

SOAP 请求是具有信封和正文的 XML 文档，请参见此处的示例 SOAP Message Example on Wikipedia。

您在此处实际执行的是模拟提交表单的标准 HTTP 调用，而不是 SOAP 调用。

这里有两种解决方案：

1- 您可以通过手动创建 XML 文档并提交它来模拟 SOAP 客户端的行为。 除了将正确的 XML 文档设置为请求正文之外，不要忘记设置正确的标头：SOAPAction、Content-Type 和 Content-Length

RequestEntity requestEntity = new StringRequestEntity("<?xml version=\"1.0\"?><soap:Envelope xmlns:soap=\"http://www.w3.org/2003/05/soap-envelope\"><soap:Header></soap:Header><soap:Body><m:GetStockPrice xmlns:m=\"http://www.example.org/stock\"><m:StockName>IBM</m:StockName></m:GetStockPrice></soap:Body></soap:Envelope>");
    post.setRequestEntity(requestEntity );

也不要忘记将上面的名称空间 (m) 更改为您的 Web 服务正在使用的正确名称空间。以及您尝试调用的操作的操作名称 (GetStockPrice )。也不要忘记参数名称和类型。

2- 您可以使用 Apache Axis 生成客户端并将该客户端与您的应用程序一起使用

Shoukry K 是对的。您已经完成了一个 HTTP POST 请求。这不是一个肥皂网络服务。如果您想知道如何调用网络服务，请点击链接。 http://www.youtube.com/watch?v=v9EowBVgwSo。确保下载最新的 ksoap jar 文件。

使用 K-SOAP for Android 的示例代码。

private void sendSOAPmsg(DamageAssessmentFormPojo pojo) throws IOException, XmlPullParserException, SoapFault {
        SoapObject request = new SoapObject(WEBSERVICE.NAMESPACE, WEBSERVICE.METHOD_NAME_SUBMIT_REPORT);
        request.addProperty("xmlBytes", Util.getSoapBase64String(pojo));
        request.addProperty("fileName", IO.DefaultReportName);
        request.addProperty("deviceId", AppConstants.IMEI != null ? AppConstants.IMEI : Util.getIMEI(this));

        SoapPrimitive response = sendSOAPEnvelope(request, WEBSERVICE.SOAP_ACTION_SUBMIT_REPORT);

        if (response.toString().equalsIgnoreCase("true")) {
            Logger.logInfo("REPORT SENT SUCCESSFULLY", "WEB-SERVICE");
            pojo.setReportSent(true);
            IO.writeObject(pojo.getReportsFolderPath() + IO.DefaultReportName, pojo);
        } else {
            Logger.logInfo("REPORT SENT FAILED", "WEB-SERVICE - RESONSE " + response.toString());
        }
    }

    private SoapPrimitive sendSOAPEnvelope(SoapObject request, String soapAction) throws IOException, XmlPullParserException, SoapFault {
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet = true;
        envelope.setOutputSoapObject(request);
        HttpTransportSE androidHttpTransport = new HttpTransportSE(WEBSERVICE.URL);

        androidHttpTransport.call(soapAction, envelope);
        SoapPrimitive response = (SoapPrimitive) envelope.getResponse();

        return response;

    }

    private boolean sendSOAPimage(String strImg, File pFile) throws IOException, XmlPullParserException {
        boolean result = false;

        if (strImg != null) {
            SoapObject request = new SoapObject(WEBSERVICE.NAMESPACE, WEBSERVICE.METHOD_NAME_SUBMIT_IMAGE);
            request.addProperty("imageBytes", strImg);
            request.addProperty("fileName", pFile.getName());
            request.addProperty("deviceId", AppConstants.IMEI != null ? AppConstants.IMEI : Util.getIMEI(this));

            SoapPrimitive response = sendSOAPEnvelope(request, WEBSERVICE.SOAP_ACTION_SUBMIT_MAGE);

            if (response.toString().equalsIgnoreCase("true")) {

                result = true;

                Logger.logInfo("IMAGE SENT SUCCESSFULLY", "WEB-SERVICE");

            } else {
                Logger.logInfo("IMAGE SENT FAILED", "WEB-SERVICE - RESONSE " + response.toString());
            }

        }

        return result;
    }

//--------Util 辅助方法
