自己调用webservice方法总结（带请求头SoapHeader）

调用webservice总结：
  1.加入第三方的jar包 Ksoap2-android-XXX 
  2.访问响应的webservice的网站，查看响应的信息，得到nameSpace，methodName，url，soapAction
  3.如果request信息还有带有SoapHander的。那么就要封装：依据参数封装
                Element[] header = new Element[1];
                header[0] = new Element().createElement(nameSpace, "SoapHeader");
               
                Element userName = new Element().createElement(nameSpace, "UserID");
                userName.addChild(Node.TEXT, UserID);
                header[0].addChild(Node.ELEMENT, userName);
               
                Element pass = new Element().createElement(nameSpace, "PassWord");
                pass.addChild(Node.TEXT, PassWord);
                header[0].addChild(Node.ELEMENT, pass);
  4.封装request信息的SoapBody
                                 // 指定WebService的命名空间和调用的方法名
                                SoapObject  soapObject=new SoapObject(nameSpace, methodName);
                                //处理soap12:Body数据部分
                                soapObject.addProperty("loginName",username);
                                soapObject.addProperty("password",password);
   5.指定SoapSerializationEnvelope信息
                SoapSerializationEnvelope   envelope=new SoapSerializationEnvelope(SoapEnvelope.VER11);
                                //SoapEnvelope.VER11 表示使用的soap协议的版本号 1.1 或者是1.2
                envelope.headerOut=header;
                envelope.bodyOut=soapObject;
                envelope.dotNet = true; //指定webservice的类型的（java，PHP，dotNet）
                envelope.setOutputSoapObject(soapObject);
        6.指定HttpTransportSE
                    HttpTransportSE ht = new HttpTransportSE(url);
        7.访问webservice服务器
                    ht.call(soapAction, envelope);
        8.两种方式获取服务器返回的信息
                                envelope.getResponse();
                                       
                            envelope.bodyIn;
                                两者的区别：Webservice开发的时候一般情况下大家接受webservice服务器返回值的时候都是使用
                            SoapObject soapObject = (SoapObject) envelope.getResponse();这个来接受返回
                                                        来的值，但这种方法往往会产生java.lang.ClassCastException: org.ksoap2.
                                                        serialization.SoapPrimitive这样的错误。
                                                        在服务器端返回值是String类型的数值的时候使用SoapObject soapObject = (SoapObject)
                            envelope.getResponse()会产生java.lang.ClassCastException: org.ksoap2.
                                                        serialization.SoapPrimitive这样的错误。
                                                        使用SoapObject result = (SoapObject)envelope.bodyIn和 Object object =
                            envelope.getResponse();就可以解决这种错误。 如果服务器返回值的类型是byte[] 的时候，
                                                        使用Object object = envelope.getResponse();和SoapObject result = (SoapObject)envelope.bodyIn;
                            都不会发生错误现象，但是在使用Object object = envelope.getResponse();
                            取回来的值在使用base64进行解码和编码的时候会报出错误。如果使用SoapObject result = (SoapObject)envelope.bodyIn;
                            就可以完整的将byte[]进行解码和编码，byte[] ops = Base64.decode(result.getProperty(0).toString());
                SoapObject result=(SoapObject) envelope.bodyIn;
                String str=result.getProperty(0).toString()；
                或者是
           Object  result=        (Object) reqVo.envelope.getResponse();
       String str=result.toString();
        9.解析字符串str获取客户端想要的信息

为什么报错，header中username password无法序列化？

请问一下,封装的头信息,在webservice中怎么取啊？？
