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

如何使用此路由转储使用 Apache Camel HTTP 组件发送的 HTTP 正文和标头：

   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 Camel DSL code in groovy. Is that possible?

Have you tried something like

你有没有尝试过类似的东西

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

Also the HTTP Component Documentationsuggests that you can extract the HttpServletRequestfrom the exchange like,

此外，HTTP 组件文档建议您可以HttpServletRequest从交换中提取，例如，

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

You can then alternatively do,

然后你也可以这样做，

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
    }
});

Try logging headers and content using one of HttpClient loggers.

尝试使用 HttpClient 记录器之一记录标头和内容。

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

是在日志记录实践（在这种情况下为 3.x 版）中进行了描述。

I am using loggers with names:

我正在使用带有名称的记录器：

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

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

which gives me output like:

这给了我这样的输出：

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 - << "Content-Type: application/octet-stream[\r][\n]"
httpclient.wire.header - << "Date: Fri, 08 Apr 2016 07:24:24 GMT[\r][\n]"

httpclient.wire.content - << "Success"

This will help , use this in log message :

这将有所帮助，在日志消息中使用它：

${headers}

${headers}

Or

或者

${in.headers}

${in.headers}

This will print any incoming headers .

这将打印任何传入的标题。
