android - 使用 KSoap 库使用 .NET Web 服务时出错

Question

我一直在使用 ksoap 库来使用 .net 网络服务。我遇到了这种错误

"expected: START_TAG {http://schemas.xmlsoap.org/soap/envelope/}Envelope (position:START_TAG @1:7 in java.io.InputStreamReader@40d0c7d8)"

我到处搜索，但找不到任何好的帮助。

这是我尝试使用网络服务的代码。

public class WebInvoke {

    private static final String NAMESPACE = "http://tempuri.org/" ;
    private static final String METHOD_NAME = "login";
    private static final String SOAP_ACTION = NAMESPACE + METHOD_NAME;
    private static final String URL = "http://10.0.2.2/Service1.asmx";
    private final SoapSerializationEnvelope envelope;


    public WebInvoke()
    {
        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

        PropertyInfo quotesProperty = new PropertyInfo();
        quotesProperty.setName("UserName");
        quotesProperty.setValue("admin");
        quotesProperty.setType(String.class);
        request.addProperty(quotesProperty);

        quotesProperty = new PropertyInfo();
        quotesProperty.setName("Password");
        quotesProperty.setValue("a");
        quotesProperty.setType(String.class);
        request.addProperty(quotesProperty);

        Log.e("Request Assign", request.toString());
        envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet = true;
        envelope.setOutputSoapObject(request);
        Log.e("Envelope Assign", envelope.toString());
    }
    public String Fetch()
    {
        String result = "";
        HttpTransportSE httpRequest = new HttpTransportSE(URL);
        try
        {
            envelope.xsd = SoapSerializationEnvelope.XSD;
            envelope.enc = SoapSerializationEnvelope.ENC;

            httpRequest.setXmlVersionTag("<?xml version=\"1.0\" encoding=\"utf-8\"?>");

             Log.e("httpRequest.call", "httpRequest.call");
            httpRequest.call(SOAP_ACTION, envelope);
            SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
            result =  response.toString();
        }
        catch(Exception e)
        {
            //e.printStackTrace();
            Log.e("httpRequest.call Exception", e.getMessage());
        }
        return result;
    }

}

尝试并获得更好的代码。您的代码听起来有点笨拙。

"org.xmlpull.v1.XmlPullParserException: expected: START_TAG" Error expected-start-tag-error

检查这个。

1. 使用 .netcode 检查您的方法名称和 url

2. 在 C# 应用代码文件中排除 app_html.offline，因为它不允许任何数据库项目运行。

希望对你有帮助。
