kSOAP2 output / org.xmlpull.v1.xmlpullparserexception期望start_tag

时间：2010-12-09 05:58:16

标签： android android-ksoap2

我有一个标准代码来调用.net webservice

我在{<1}}行

exception "org.xmlpull.v1.xmlpullparserexception expected start_tag"

但是，如果我从transportSE.call(SOAP_ACTION,soapSerializationEnvelope); 调用相同的Web服务，我会根据需要获得结构合理的正确输出。

主要看来，从.NET code开始，它有一个明确的输出，但是当它进一步解析w.r.t SoapPrimitive对象时，它会失败。

那么，是否有其他方法可以查看收到的实际输出（实际肥皂信封），然后可以自己解析它。

我正在调查我遇到的类似问题。偶然发现了这条评论

  

当我使用SoapEnvelope.VER11时，它工作正常，但是当我使用时   SoapEnvelope.VER12，它给了我错误：   “org.xmlpull.v1.XmlPullParserException：expected：START_TAG”。

也许我们遇到有关soap版本的兼容性问题。同样连接到dot net服务，您可能需要设置envelope.dotNet = true; ..但您可能已经完成了

我收到了这个START_TAG例外，但就我而言，这是因为我的

值 
METHOD_NAME="";
NAMESPACE ="";      
SOAP_ACTION ="";
URL ="";

不正确。

现在如何查找这些参数的正确值Check out my other answer here 

SoapObject req = new SoapObject(NAMESPACE,METHOD_NAME);
            //SoapObject req = new SoapObject(Namespace_Server,MethodName_Server);

    //req.addProperty("ImageData", Base64.encode(data));
    req.addProperty("ImageData", data);
    req.addProperty("login", CommonStaticData.getusername());
    req.addProperty("password",CommonStaticData.getpassword());
    req.addProperty("recipeId",FileID);

    MarshalBase64 mbase = new MarshalBase64();// marshal is used to serialize the byte array

    SoapSerializationEnvelope envelop = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelop.bodyOut = req;
    envelop.encodingStyle = SoapSerializationEnvelope.ENC2001;
    envelop.dotNet = true;
    envelop.setOutputSoapObject(req);


    HttpTransportSE aht = new HttpTransportSE(URL);

    mbase.register(envelop);


    aht.call(SOAP_ACTION,envelop);

现在好了，我已经解决了我的原始问题！

我发现ksoap2无法解析响应...特别是org.kxml2.io.KXmlParser.require（type，namespace，name）引发了以下异常。

WARN/System.err(2330): org.xmlpull.v1.XmlPullParserException: expected: START_TAG {http://www.w3.org/2001/12/soap-envelope}Envelope (position:START_TAG <h1>@1:4 in java.io.InputStreamReader@47ff3050)

注意h1标签。这来自<h1>404 Not Found</h1> ...是的，请注意您的回复可能来自网站但不是您的网络服务：）

希望有一天可以帮助某人

答案 3 :(得分：0)

我有几乎相同的错误，我的例外是这个“位置：START_TAG @ 2：7”

但我已修复，因为我以错误的方式命名参数，名称必须与XSD上指定的完全相同。

     SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
     request.addProperty("arg0_java_lang_String", "Club");

在 addPropery 方法中，我使用了错误的参数名称。

通过使用以下代码确保网络服务的网址可访问后，通过观察变量 urlc.getResponseCode() 获取响应代码，同时从更改IP localhost，fixed，external，最后到10.0.2.2

    }

对我来说，我得到了这个暗示“下面不是缺少的字符 s ”

在追踪LogCat之后我没有检查tomcat服务器日志前夕如果SoapUi成功测试了服务，你应该监控每个变更测试中的所有日志，我甚至忘了一开始就启动数据库服务所以要小心:)）

肥皂电话 

public SoapObject SoapCall(Vector<PropertyInfo> propertyInfo)

    {       

         Integer parametersSize = propertyInfo.size();

         //Initialize soap request + add parameters
         SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

         for(int i=0;i<parametersSize;i++)
         {
             request.addProperty(propertyInfo.get(i));
         }


        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        //envelope.dotNet = false; if service of type asmx .NET
        envelope.setOutputSoapObject(request);

        Log.d("App Log c ","c");

        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        try {
            System.out.println(androidHttpTransport.getPort());
            // Make the soap call.
            //this is the actual part that will call the webservice
             androidHttpTransport.call(SOAP_ACTION, envelope);                      

             SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
             //Log.i("App Log 1 ", response.toString());

        } catch (Exception e) {
            e.printStackTrace(); 
        }

        // Get the SoapResult from the envelope body.       
        SoapObject result = (SoapObject)envelope.bodyIn;
        Log.i("App Log 2 ", result.toString());
        Log.i("App Log 2 ", result.getProperty(0).toString());

        return result;

    }




 Vector<PropertyInfo> vectorProperyInfo = new Vector<PropertyInfo>();

            PropertyInfo userProp = new PropertyInfo();
            userProp.setName("userName");
            userProp.setValue(username);
            userProp.setType(String.class);
            vectorProperyInfo.addElement(userProp);

            PropertyInfo passProp = new PropertyInfo();
            passProp.setName("pass");
            passProp.setValue(password);
            passProp.setType(String.class);
            vectorProperyInfo.addElement(passProp);

            SoapObject result = soapUtil.SoapCall(vectorProperyInfo);

           if (result != null && result.getProperty(0).toString().equals("1")) {
            return "LOGIN_SUCCESS";// for a student
        }

P.S 我的Db是Oracle和webservice是肥皂并使用axis2-1.2 bin并在Android 4.0上测试了以上错误响应代码为500 Internal Error
