Class WLResourceRequest

java.lang.Object

com.worklight.wlclient.api.WLResourceRequest

public class WLResourceRequest
extends java.lang.Object

This class encapsulates a resource request.

The resource can be an adapter that is deployed to an instance of MobileFirst Server, or a resource on an external resource server.
The class provides several send methods with different inputs for the body of a request.
In addition, the send methods support the WLResponseListener response listener. The onSuccess method of this listener is called with an instance of the WLResponse class. The content of the response is read by the security framework into the WLResponse instance, and is then accessible through WLResponse methods. In case of failure, the onFailure method of the listener is called with an instance of the WLFailResponse class, which contains all the information about the failure.
A successful response is any response with a status in the 2xx range. These responses are delivered to the onSuccess method.
A response with a 4xx or 5xx status is considered a failure, and is delivered to the onFailure method.

The WLResourceRequest API can be used to allow mobile apps access to microservices hosted outside of Mobile Foundatione. Mobile Foundation facilitates secure calls to microservice or enterprise backend service without involving adapters though Mobile Foundation API Connector.

To access a microservice URL such as "http://mybluemix.net/resorts/cities" and the Mobile Foundation runtime backend service is configured as follows

{"service": "resorts", "baseUrl":"http://mybluemix.net/resorts"}

Parameters:

url - Relative URL of the microservice endpoint. For example : cities

method - HTTP method to use.

backendServiceName - Name of the backend service configured on server to fetch data from. For example :resorts

timeout - The timeout in milliseconds for this request. For example : 3000
