How to reset HTTP body and headers sent with HTTP component with Apache Camel

How to reset the body and HTTP headers sent with the Apache Camel HTTP component using this route:

   from('direct:abc').
   setHeader(Exchange.HTTP_URI, constant("${config.gnutch.solr.coreUrl}/select")).
   setHeader(Exchange.HTTP_QUERY, constant("q=${q}&wt=xml")).
   setHeader(Exchange.CONTENT_TYPE, constant('application/xml')).
   setHeader(Exchange.HTTP_METHOD, constant('GET')).
   setBody(constant(null)).
   to("http://null")

This is the Camel DSL code in groovy. Is it possible?

Have you tried something like

from("direct:abc")
 .to("http://domain.com/")
 .to("log:DEBUG?showBody=true&showHeaders=true")

In addition, HTTP Component Documentation offers you to extract HttpServletRequestfrom exchange, for example,

HttpServletRequest request = exchange.getIn().getBody(HttpServletRequest.class);

Then you can do it,

from("direct:abc").to("http://domain.com").process(new Processor() {
    public void process(Exchange exchange) throws Exception {
        HttpServletRequest request = exchange.getIn().getBody(HttpServletRequest.class);
        // Log request parameters
    }
});

This will help, use this in a log message:

$ {headers}

Or

$ {in.headers}

This will print all incoming headers.

Try recording headers and content using one of the HttpClient protocols.

Is described in Logging Practices (version 3.x in this case).

I use registrars with names:

  • httpclient.wire
  • org.apache.commons.httpclient.HttpConnection

which gives me the output, for example:

o.a.c.httpclient.HttpConnection - Open connection to 0.0.0.0:12454
httpclient.wire.header - >> "POST /some/path HTTP/1.1[\r][\n]"
httpclient.wire.header - >> "breadcrumbId: ID-localhost-55077[\r][\n]"
httpclient.wire.header - >> "path: http://0.0.0.0:65432/some/other/path[\r][\n]"
httpclient.wire.header - >> "User-Agent: Jakarta Commons-HttpClient/3.1[\r][\n]"
httpclient.wire.header - >> "Host: 0.0.0.0:12454[\r][\n]"
httpclient.wire.header - >> "Content-Length: 117[\r][\n]"
httpclient.wire.header - >> "[\r][\n]"
httpclient.wire.content - >> "{"a":"afeaafe","b":{"c":"53413"},"d":{"e":"vsegefawawewr"}}"
httpclient.wire.header - << "HTTP/1.1 200 OK[\r][\n]"
httpclient.wire.header - << "HTTP/1.1 200 OK[\r][\n]"
httpclient.wire.header - << "Date: Fri, 08 Apr 2016 07:24:24 GMT[\r][\n]"
httpclient.wire.header - << "Content-Type: application/octet-stream[\r][\n]"
httpclient.wire.header - << "Date: Fri, 08 Apr 2016 07:24:24 GMT[\r][\n]"
httpclient.wire.header - << "Content-Length: 7[\r][\n]"
httpclient.wire.header - << "Server: Jetty(9.2.10.v20150310)[\r][\n]"
httpclient.wire.header - << "[\r][\n]"
httpclient.wire.content - << "Success"
