Question

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")

这是groovy中的Camel DSL代码。这可能吗？

Answer 1

你有没有试过像

这样的东西

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

此外，HTTP Component Documentation表示您可以从交换中提取HttpServletRequest，例如

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

然后你可以做，

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
    }
});

Answer 2

这将有所帮助，请在日志消息中使用：

$ {头}

或

$ {in.headers}

这将打印任何传入的标头。

尝试使用HttpClient记录器之一记录标题和内容。

在Logging Practices（本例中为3.x版）中描述了。

我正在使用名称为

的记录器

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

这给我的输出如下：

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]"
