WSDL/Soap web service response complex array parsing using KSOAP2 library - php

Question

I have created PHP web service using nusoap
$namespace="http:/mynamespace.com/mynamespace"
$server = new soap_server();
$server->debug_flag = false;
$server->configureWSDL("test", $namespace);
$server->wsdl->schemaTargetNamespace = $namespace;
$server->wsdl->addComplexType(
'Products',
'complexType',
'struct',
'all',
'',
array('ID' => array('name' => 'ID','type' => 'xsd:int'),
'ProductName' => array('name' => 'ProductName','type' => 'xsd:string'),
'ImageUrl' => array('name' => 'ImageUrl','type' => 'xsd:string')
)
);
$server->wsdl->addComplexType(
'ProductsArray',
'complexType',
'array',
'',
'SOAP-ENC:Array',
array(),
array(
array('ref'=>'SOAP-ENC:arrayType','wsdl:arrayType'=>'tns:Products[]')
),
'tns:Products'
);
$server->register('GetProductDetails', // method name
array('AgentId' => 'xsd:string'), // input parameters
array('return' => 'tns:ProductsArray'), // output parameters
$namespace, // namespace
$namespace . '#GetProductDetails', // soapaction
'rpc', // style
'sequence', // use
'Get Product Details' // documentation
);
function GetProductDetails($AgentId)
{
$productArray = array();
$sqlQry="SELECT pr.products_id, pr.products_image, pd.products_name FROM `products` pr left join products_description pd on pr.products_id=pd.products_id";
$result=mysql_query($sqlQry);
while($row=mysql_fetch_array($result)){
$product=array();
$product["ID"]=$row['products_id'];
$product["ProductName"]=$row['products_name'];
$product["ImageUrl"]=$row['products_image'];
$productArray[]=$product;
}
return $productArray;
}
$HTTP_RAW_POST_DATA = isset($GLOBALS['HTTP_RAW_POST_DATA'])?$GLOBALS['HTTP_RAW_POST_DATA'] : '';
$server->service($HTTP_RAW_POST_DATA);
and I am getting response in android something like
[Products{ID=29; Name=product1; Url=product1.jpg; }, Products{ID=30; Name=product2; Url=product2.jpg; }]
this responce is in one element of response.getProperty(0)
and if I paste this code in http://jsonviewer.stack.hu/ site then it tells me it is not valid json, I am new in nusoap so I don't know how this gives json/XML response
Is there any problem with code?
I have also tried
Android Code:
SoapObject response = (SoapObject) envelope.bodyIn;
SoapObject nameResult = (SoapObject) response.getProperty(0);
In above nameResult I am getting all response in one single property.

I have never used nusoap before but from what I can tell your properly connecting to your db, and according to what i found nusoap can run standard php scripts in which case replaces function GetProductDetails with what i have below (I'm using json_encode), Your problem was with how you load a single result inside the while loop you must use array_push() instead.
function GetProductDetails($AgentId)
{
// array for JSON response
$productArray = array();
$sqlQry="SELECT pr.products_id, pr.products_image, pd.products_name FROM `products` pr left join products_description pd on pr.products_id=pd.products_id";
$result=mysql_query($sqlQry);
while ($row = mysql_fetch_array($result)) {
// temp user array
$product=array();
$product["ID"]=$row['products_id'];
$product["ProductName"]=$row['products_name'];
$product["ImageUrl"]=$row['products_image'];
// push single product into final response array
array_push($poductArray["products"], $product);
}
// echoing JSON response
echo json_encode($productArray);
}
Hope this works it's clearly untested as I dont have your sql (but it's copied from similar script on my server and rewritten for your purposes) also you should cover the case your database is empty

I have solved it by my self, this is help here if any one needs how to solve this..
I am getting response is parsed using Vector and after that I just simply make a loop that get every attribute and add to ArrayList<HashMap<String, String>>.
My process is like, get response from webservice and parsing that response using vector and I just retrieve properties and add to ArrayList<HashMap<String, String>>.
So If here anyone wants to parse complexType Array Response and finds problem like me, they can find solution like following code
public static final ArrayList<HashMap<String, String>> productMapArray = new ArrayList<HashMap<String, String>>();
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
envelope.dotNet = true;
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
request.addProperty("user_id", "1");
try {
androidHttpTransport.call(SOAP_ACTION, envelope);
Vector<SoapObject> response = (Vector<SoapObject>)envelope.getResponse();
for (SoapObject soapObject : response) {
HashMap<String, String> map = new HashMap<String, String>();
map.put(KEY_ID, soapObject.getProperty(KEY_ID).toString());
map.put(KEY_PRODUCT, soapObject.getProperty(KEY_PRODUCT).toString());
map.put(KEY_IMG, soapObject.getProperty(KEY_IMG).toString());
productMapArray.add(map);
}
if (response.toString().equalsIgnoreCase("invalid")) {
result = false;
} else {
result = true;
}
} catch (SocketException ex) {
result = false;
Log.e("Error : ", "Error on soapPrimitiveData() " + ex.getMessage());
ex.printStackTrace();
} catch (Exception e) {
result = false;
Log.e("Error : ", "Error on soapPrimitiveData() " + e.getMessage());
e.printStackTrace();
}
return result;
