Question

我想知道如何解析SOAP的输出。我目前的代码如下：

try{
    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.setOutputSoapObject(request);
    HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
    androidHttpTransport.call(SOAP_ACTION, envelope);

    Object response = (Object) envelope.getResponse();   

    Log.e("Output:", response.toString());

}catch (Exception e){
    Log.e("Error:", e.getCause().toString());
}

响应的输出是：

[{ “CATEGORY_ID”：767， “PARENT_ID”：663， “姓名”： “走”}， { “CATEGORY_ID”：768， “PARENT_ID”：767， “名”： “谷歌”}， { “CATEGORY_ID”：764， “PARENT_ID”：697， “姓名”： “黄色”}]

那么，我如何单独获取这些值？

我只想告诉你，如果我改变这一行：

Object response = (Object) envelope.getResponse();

对此：

SoapObject response = (SoapObject) envelope.getResponse();

我收到以下错误：

感谢。

Answer 1

从你的评论中你需要解析json数组。

 JSONArray jr = new JSONArray("jsonstring");
 for(int i =0 ; i< jr.length();i++)
 {
 JSONObject jb =(JSONObject) jr.get(i);  
 String categoryid = jb.getString("category_id");
 String parent_id = jb.getString("parent_id");
 String name = jb.getString("name");
 }

感谢 @Raghunandan 。此外，它检索正确的编码，这很棒，因为json_encode在字符串上放置了特殊字符。

try{
    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.setOutputSoapObject(request);
    HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
    androidHttpTransport.call(SOAP_ACTION, envelope);

    SoapObject rep = (SoapObject) envelope.bodyIn;

    JSONArray jr = new JSONArray(rep.getPropertyAsString(0));
    for(int i =0 ; i< jr.length();i++)
     {
         JSONObject jb =(JSONObject) jr.get(i);  

         String name = jb.getString("name");
         Log.e("value:", name);
     }

}catch (Exception e){
    Log.e("Error:", e.toString());
}
