今天写了一个判断记录重复的webservcie 返回布尔类型
1 // 判断序列号在数据库是否重复 2 public static boolean isSerialNumExist(String serialNumber) 3 throws IOException, XmlPullParserException { 4 boolean isExist = false; 5 String methodName = "IsSerialNumberExist"; // 方法名 6 HttpTransportSE ht = new HttpTransportSE(SERVICE_URL); //SERVICE_URL为 webservice的地址 7 SoapSerializationEnvelope envelope = new SoapSerializationEnvelope( 8 SoapEnvelope.VER12); 9 SoapObject soap = new SoapObject(SERVICE_NS, methodName); 10 // 传入参数 11 soap.addProperty("serialNumber", serialNumber); 12 envelope.bodyOut = soap; 13 // 设置webservice的提供者为.net平台的 14 envelope.dotNet = true; 15 ht.call(SERVICE_NS + methodName, envelope); 16 // SoapObject in = (SoapObject) envelope.getResponse(); 17 String response=envelope.getResponse().toString(); //值为： false 18 SoapObject in = (SoapObject) envelope.bodyIn; 19 // String bodyIn=in.toString(); 20 // 值为：IsSerialNumberExistResponse{IsSerialNumberExistResult=false; } 21 if (in != null) { 22 isExist = Boolean.valueOf(in.getProperty(methodName + "Result") 23 .toString()); 24 } 25 return isExist; 26 }
一、SoapSerializationEnvelope携带输出参数与返回值:
(1)其属性bodyIn为SoapObject类型 内容格式为 methodName+Response{
methodName+Result=值;... } （要是返回的是字符串数组：
methodName+Response{ methodName+Result=anyType{stirng=value1;string=value2;...} }）
获取指定属性的值:
SoapObject in = (SoapObject)
envelope.bodyIn;
in.getProperty(methodName+Result).toString();
(2)而我通过
getResponse()获取的返回值直接就是false （要是返回值是字符串数数组 其格式为： anyType{ string=value1;
stirng=value2;...} ）不能转换成SoapObject类型，此时貌似getResponse()就是什么soapprimitive类型了;
数组的话可以转换；
所以在使用的时候要么try catch 要么直接用bodyIn 就不会出错的样子，如下：
SoapObject result=null; try{ result = (SoapObject) soapEnvelope.getResponse(); } catch (ClassCastException e) { result = (SoapObject)soapEnvelope.bodyIn; }
二、不过还一个问题是: 这两种获取返回值的方式会有所不同,具体体现为 result.getProperty(String name) 传入的参数差异
返回单个值：
1 getResponse(): 2 object response=envelope.getResponse(); 3 4 bodyIn: 5 object in=in.getProperty(methodName + "Result");
返回字符串数组：
1 getResponse: 3 if (soapIn != null) 4 { 5 int count = soapIn.getPropertyCount(); // 属性个数 6 for (int i = 0; i < count; i++) 7 { 8 soapIn.getProperty(i).toString(); // do as you like 9 } 10 } 11 12 bodyIn: 13 14 if (soapIn != null) 15 { 16 SoapArray soapArray=soapIn.getProperty(methodName+"Result"); // 差异 17 int count = soapArray.getPropertyCount(); // 属性个数 18 for (int i = 0; i < count; i++) 19 { 20 soapArray.getProperty(i).toString() 21 } 22 }
