Message Body

Camel will store the http response from the external server on the OUT body. All headers from the IN message will be copied to the OUT message so headers is preserved during routing.
Additionally Camel will add the http response headers as well to the OUT message.

...

In the sample above Camel will call the http://newhost despite the endpoint is configured with http://oldhost.

And the same code in Camel 2.0:

Code Block

        from("direct:start")
            .setHeader(Constants.HTTP_URI, constant("http://newhost"))
	    .to("http://oldhost");

Where Constants is the class org.apache.camel.component.http.Constants.

Configuring URI Parameters

...

Code Block
        from("direct:start")
            .setHeader(org.apache.camel.component.http.HttpProducer.Constants.HTTP_QUERY, constant("order=123&detail=short"))
	    .to("http://oldhost");

...

Code Block
        from("direct:start")
            .setHeader(org.apache.camel.component.http.HttpMethods.Constants.HTTP_METHOD, constant(org.apache.camel.component.http.HttpMethods.POST))
	    .to("http://www.google.com")
            .to("mock:results");

The method can be written a bit shorter using the string constantconstants:

Code Block
            .setHeader(org.apache.camel.component.http.HttpMethods.HTTP_METHOD"CamelHttpMethod", constant("POST"))

And the equivalent spring sample:

Code Block
xml
xml
<camelContext xmlns="http://activemq.apache.org/camel/schema/spring">
  <route>
    <from uri="direct:start"/>
    <setHeader headerName="http.requestMethodCamelHttpMethod">
        <constant>POST</constant>
    </setHeader>
    <to uri="http://www.google.com"/>
    <to uri="mock:results"/>
  </route>
</camelContext>
