CortexClientFactory provides the Cortex client instance. To obtain an new Cortex client instant, inject the Factory and pass in a MultiValuedMap with the header and the scope (the store code) to the factory.

			@Reference
			com.elasticpath.rest.client.CortexClientFactory clientFactory;
			...
			MultivaluedMap<String, Object> headers = new MultivaluedHashMap<String, Object>();
			headers.putSingle(HeaderKeys.X_EP_USER_ID_KEY, "customerId");
			headers.putSingle(HeaderKeys.X_EP_USER_ROLES_KEY, "PUBLIC");
			headers.putSingle(HeaderKeys.AUTHORIZATION_KEY, "authToken");
			com.elasticpath.rest.client.CortexClient client = clientFactory.create(headers, scope);

To use the Cortex client in a non-OSGi environment, you need to manually instantiate the required beans. The following example shows how to use a Spring application context with the Cortex client.

URLs with Zoom or FollowLocation query parameters can be constructed by calling the createResourceUrlWithQueryParameters method:

baseUrl = "http://localhost:9080/cortex/"
path = "carts/mobee/default"
result = cortexUrlFactory.addQueryParametersToResourceUrl(baseUrl, path, Cart.class)
//result = "http://localhost:9080/cortex/carts/mobee/default?zoom=order&followLocation=true"
Copy

URLs without query parameters can be constructed by calling the createResourceUrl method:

baseUrl = "http://localhost:9080/cortex/"
path = "carts/mobee/default"
result = cortexUrlFactory.createResourceUrl(baseUrl, path)
//result = "http://localhost:9080/cortex/carts/mobee/default"
Copy

@EntryPointUri(“carts/{scope}/default”)
@Zoom(@Path("lineitems"))
@FollowLocation
public class Carts {}
Copy

URLs using entry point URIs can be constructed by calling the createResourceUrlFromAnnotations method:

baseUrl = “http://localhost:9080/cortex/”
store = “mobee”
result = cortexUrlFactory.createResourceUrlFromAnnotations(baseUrl, store, Carts.class)
//result = "http://localhost:9080/cortex/carts/mobee/default?zoom=lineitems&followLocation=true" 
Copy

Extract a single, non-nested, JSON property:

public class Cart {)
  @JsonProperty("total-quantity")
  private String totalQuantity;
}
Copy

Extract nested JSON properties:

public class Cart {
  //Non-nested JSON property
  @JsonPath("$.total-quantity")
  private int totalQuantity;
 
  //Nested Property
  @JsonPath("$._lineitems[0]._element[0].quantity")
  private int quantity;
 
  //Nested Array 
  @JsonPath("$._lineitems[0]._element")
  private List<LineItem> lineItems;
}
