Configuring for Request (Outbound) Flow

You can configure outbound messages sent from a reference by configuring the following:
  • Supported Type: Basic, Bag
  • Supported Header Source: HTTP_HEADERS
  • Direction: Outbound

Add the following code.

To set a 'Basic' context parameter: 

//Create a new Mutable requestContext from componentContext to set context parameters for Reference-side
MutableRequestContext createMutableRequestContext = componentContext.createMutableRequestContext();
		
createMutableRequestContext.setParameter("bookNameCP", String.class, "How to Kill a Mockingbird");

The value How to Kill a Mockingbird is set for the HTTP Header bookName (corresponding to context parameter bookNameCP) in the outgoing REST Request.

To set a context parameter 'Bag': 

//Create a new Mutable requestContext from componentContext to set context parameters for Reference-side
MutableRequestContext createMutableRequestContext = componentContext.createMutableRequestContext();
		
HashMap<String, String> requestHeadersAllCP_reference_map = new HashMap<String, String>();
requestHeadersAllCP_reference_map.put("bookAuthor", "Harper Lee");
requestHeadersAllCP_reference_map.put("bookPublishYear", "1960");
createMutableRequestContext.setParameter("requestHeadersAllCP", Map.class, requestHeadersAllCP_reference_map);

The contents of the HashMap requestHeadersAllCP_reference_map are set as HTTP Headers (user-defined, corresponding to context parameter requestHeadersAllCP) in the outgoing REST Request.
