我有一个由Apache Camel支持的小型Java Web应用程序。它使用Camel的servlet组件。此应用程序用于连接器和从设备接收数据。
就我们支付流量而言,如果有办法拒绝来自网络服务器的所有响应标头并仅发送状态代码,我会感兴趣。
更新
from("servlet:///channel?servletName=ChannelServlet")
...
.split().method("objectSplitter", "splitRootObject")
.log("before removeHeaders")
.removeHeaders("*")
.log("after removeHeaders")
.process(new Processor() {
@Override
public void process(Exchange exchange) throws Exception {
Message out = exchange.getOut();
out.removeHeaders("*");
out.setHeader("custom", "custom");
out.setHeader(Exchange.HTTP_RESPONSE_CODE, "200");
out.setBody("");
LOG.debug("In processor");
}
});
我一直在接受:
HTTP/1.1 200 OK

您可以告诉Camel删除路径末尾的所有标头。然后响应没有任何标题。
from("jetty:...")
...
.removeHeaders("*");
还可以看到其中一些页面

这个问题的最终答案是你可以从Camel中删除大部分标题,但Tomcat / Jetty无论如何都会追加其中的一些标题。我得到的最小标题是:
Date: Thu, 30 May 2013 09:49:30 GMT
Transfer-Encoding: chunked
Content-Length: 0
Server: Apache-Coyote/1.1
在我的情况下,这仍然是不可接受的,因此我将使用Apache Mina和UDP / TCP而不是HTTP。
