我在连接到我的 Web 服务时遇到问题。我遵循了一些教程，尤其是http://drclawx.wordpress.com/2011/06/24/77/并创建了一个简单的 Wcf Hello World Web 服务。我已经下载了网站上推荐的 ksoap2 jar，但我遇到了一些问题。我已经下载了几个更高的版本，但我可以开始工作的是 2.5.8 版。当我调用自己的 Web 服务时，我得到了 XMLPullParserException。我的 Web 服务将用于检查登录凭据，它有一个名为“UploadLogin”的方法，它接受用户名和密码。以下是我的代码

private class webService extends AsyncTask<String, Void, Void> {

    final String METHOD_NAME = "UploadLogin";
    final String NAMESPACE = "http://tempuri.org/";     
    final String URL = "http://10.0.2.2:52762/UploadService.svc";
    final String SOAP_ACTION = "http://tempuri.org/IUploadService/UploadLogin";

    // For the web service method: public String getLocations(String inputLocation))
    @Override
    protected Void doInBackground(String... entry) {

        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
        request.addProperty("username", "a");
        request.addProperty("password", "a");
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

        envelope.dotNet = true;
        envelope.setOutputSoapObject(request);
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

        try {
            androidHttpTransport.call(SOAP_ACTION, envelope);

            Object response = (Object) envelope.getResponse();
            System.out.println("Login - " + response.toString());
        } 
        catch (Exception exception) {
            exception.printStackTrace();   
        }

        return null;
    } 
}

我得到的错误如下。有人可以帮助或建议我如何解决这个问题。

Instead of using kSOAP library, you can do it with built-in apache classes like HttpClient, HttpGet, HttpPost, etc.

For example: You want to send below JSON object:

{
   "email":"test@test.com",
   "password":"test"
}
then you can set your request object by using setEntity():

final String body = String.format("{\"email\":\"%s\",\"password\":\"%s\"}", s1, s2);

HttpClient client = new DefaultHttpClient();
HttpPost postMethod = new HttpPost(webServiceUrl);
postMethod.setEntity(new StringEntity(body, "utf-8"));

对于任何感兴趣的人，我收到此错误的原因是因为 messageEncoding 使用的是 MTOM，所以我将其更改为 Text 并且它可以工作 - messageEncoding="Text"

在我的情况下，由于缺少所需的方法参数而发生错误：

    request.addProperty("cpf", "111111111");
