  • Ksoap2 获取webservice返回值的getResponse() 出现的问题

    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 }
