如何用Apache Camel转储HTTP组件发送的HTTP正文和头

Question

   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")

这是Groovy中的骆驼DSL代码。有可能吗？

Answer 1

你有没有试过

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

HTTP组件文档还建议您可以从exchange中提取HttpServletRequest,

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

然后,您可以执行另一种操作,

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
    }
});
