我想知道如何解析 SOAP 的输出。我当前的代码如下:
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());
}
响应的输出是这样的:
[{"category_id":767,"parent_id":663,"name":"Walk"}, {"category_id":768,"parent_id":767,"name":"Google"}, {"category_id": 764,"parent_id":697,"name":"黄色"}]
那么,如何分别获取这些值呢?
我只是想让你知道,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:
