Comment passer tableau JSON comme paramètre à une Webservice utilisant Ksoap2 dans Android

Question

Mon code est donné ci-dessous:

public void testWebServiceForJson() { 

TextView textView = new TextView(this); 

setContentView(textView); 

SoapObject request = new SoapObject(WSDL_TARGET_NAMESPACE, 
    OPERATION_NAME); 

ArrayList<String> list = new ArrayList<String>(); 
list.add("blah"); 
list.add("bleh"); 
JSONArray jsArray = new JSONArray(list); 

String mStringArray[] = { "String1", "String2" }; 
JSONArray mJSONArray = new JSONArray(Arrays.asList(mStringArray)); 


request.addProperty("jsonArray", mJSONArray); 
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
    SoapEnvelope.VER11); 
envelope.dotNet = true; 

envelope.setOutputSoapObject(request); 

HttpTransportSE httpTransport = new HttpTransportSE(SOAP_ADDRESS); 

try 

{ 

    httpTransport.call(SOAP_ACTION, envelope); 

    Object response = envelope.getResponse(); 
    // SoapObject result = (SoapObject) envelope.bodyIn; 

    textView.setText("fafaf"); 

} 

catch (Exception exception) 

{ 
    exception.printStackTrace(); 
    textView.setText(exception.toString()); 

} 

} 

Une exception est levée:

Vous n'avez pas devez utiliser ksoap2 pour envoyer json au serveur. Ksoap est utilisé pour communiquer avec le webservice de savon.

• utilisation de savon xml http://en.wikipedia.org/wiki/SOAP

• Json utilisation web-service, eh bien, JSON http://en.wikipedia.org/wiki/Json

Pour envoyer JSON au serveur:

Reader r; 
String url = "http://10.111.111.43:9000/XentivoCrm/services/VisitJSON"; 
DefaultHttpClient httpClient = new DefaultHttpClient(); 
HttpPost httpost = new HttpPost(url); 
InputStream data = null; 
try { 
    ObjectMapper mapper = new ObjectMapper();   
    mapper.getSerializationConfig().setSerializationInclusion(JsonSerialize.Inclusion.NON_NULL); 
    String json = mapper.writeValueAsString(mStringArray); 
//I used jackson to create json, but built-in json.org will work 
     StringEntity se = new StringEntity(json); 
     httpost.setEntity(se); 
     httpost.setHeader("json", "application/json"); 
     httpost.setHeader(HTTP.CONTENT_TYPE, "application/json"); 
     HttpResponse response = httpClient.execute(httpost); 
    }
