Using BODY as HTTP Query String Parameter...

[James Carman <ja...@carmanconsulting.com>]

There is a web service at my company that returns XML documents, but
you have to query it using a query string.  I want to send the single
parameter (an id) as the body of the incoming message and I want to
append that body value to the HTTP URL.  So, I want something like:

http://my.service.url/service.cgi?id=${body}

Is that possible using the Java DSL?

Thanks,

James

p.s. Camel Rocks!  I've downloaded the MEAP Camel in Action book and
I'm working my way through it.  Very cool indeed!

Hi,

You could set the message with Exchange.HTTP_QUERY to let the http 
producer pick up the query string dynamically.

Here is the example

from("direct:start").setHeader(Exchange.HTTP_QUERY). 
simple("id=${body}")).to("http://XXXX");

Yes you can for example use the setHeader to set the id header beforehand

.setHeader("id").simple("${body}").to("http://xxxx");

Or use the recipient list to construct a dynamic uri
http://camel.apache.org/recipient-list.html

.recipientList().simple("http://xxxx?id=${body}");

We use the Camel expression language, simple, to define the dynamic expression:
http://camel.apache.org/simple.html
