Java 如何使用ApacheCamel转储HTTP组件发送的HTTP正文和标头

如何使用此路由转储与Apache Camel HTTP组件一起发送的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")

这是groovy中的骆驼DSL代码。可能吗？

你试过类似的方法吗

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

还建议您可以从exchange中提取

HttpServletRequest

，如

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

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
    }
});

尝试使用一个HttpClient记录器记录标题和内容

如（本例中为3.x版）所述

我正在使用具有以下名称的记录器：

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

这给了我如下输出：

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 - << "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"
o.a.c.httpclient.HttpConnection - Releasing connection back to connection manager.

o.a.c.httpclient.HttpConnection-打开到0.0.0.0:12454的连接
httpclient.wire.header->“POST/some/path HTTP/1.1[\r][\n]”
httpclient.wire.header->“breadcrumbId:ID-localhost-55077[\r][\n]”
httpclient.wire.header->“路径：http://0.0.0.0:65432/some/other/path[\r][\n]“
httpclient.wire.header->“用户代理：雅加达公用httpclient/3.1[\r][\n]”
httpclient.wire.header->“主机：0.0.0.0:12454[\r][\n]”
httpclient.wire.header->“内容长度：117[\r][\n]”
httpclient.wire.header->“[\r][\n]”
httpclient.wire.content->“{”a:“afeaafe”，“b:{”c:“53413”}，“d:{”e:“vSegefawawr”}”
httpclient.wire.header-这将有所帮助，请在日志消息中使用此选项：

${headers}

或

${in.headers}

这将打印任何传入的标题

示例：
第一个解决方案不打印请求正文。第二种解决方案似乎提供了这种能力，但这不应该是处理器，而是类型转换器。我将修复您的回复并接受它。在上述情况下如何读取HttpServletResponse头和正文，因为HttpServletResponse类没有getInputStream（）方法。
