webservice总结

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);?
? 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.?
??????????????????????????????????????????????????????? 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
