Question

路线：

  from("direct:start")
  .setProperty(Exchange.CHARSET_NAME, constant("iso-8859-1"))
  .process(new Processor() {            
        @Override
        public void process(Exchange exchange) throws Exception {
          Message m = exchange.getOut();
          m.setBody(exchange.getIn().getBody());
          m.setHeader(Exchange.HTTP_METHOD, HttpMethods.POST);
          m.setHeader(Exchange.CONTENT_ENCODING, "gzip" );
          m.setHeader(Exchange.CONTENT_LENGTH, m.getBody(byte[].class).length );
          m.setHeader(HttpHeaders.CONTENT_TYPE, "application/xml");
          m.setHeader(Exchange.HTTP_CHARACTER_ENCODING, "iso-8859-1");
          m.setHeader(HttpHeaders.ACCEPT_ENCODING, "gzip, deflate");        
        }
    })
  .marshal().gzip()
  .to("http4://remote.com/path")
  .unmarshal().gzip();

我发送的内容：

String body = "<?xmlversion=\"1.0\"encoding=\"ISO-8859-1\"?><theXml></theXml>";
producer.sendBody(body);

我正在

HTTP操作无法使用statusCode：411
调用http://remote.com/path

这条路线有什么遗漏/错误？

修改

正确的路线是

  from("direct:start")
  .process(new Processor() {            
        @Override
        public void process(Exchange exchange) throws Exception {
          Message m = exchange.getOut();
          m.setBody(exchange.getIn().getBody());
          m.setHeader(Exchange.HTTP_METHOD, HttpMethods.POST);
          m.setHeader(Exchange.CONTENT_ENCODING, "gzip" );
          m.setHeader(Exchange.CONTENT_TYPE, "application/xml");        
        }
    })
  // http4 takes care of compressing/decompressing gzip
  .to("http4://remote.com/path")

但是现在我还有另外一个问题：远程服务器没有处理“Transfer-Encoding：Chuncked”这似乎是camel-http4的默认方式。我无法弄清楚如何关闭 Chunked 。

请参阅下一个问题How to turn off “Transfer-Encoding Chuncked” in Camel-http4?

您正在从未编码数据的长度设置内容长度。它应该是传输数据的长度。请参阅此SO问题： content-length when using http compression

顺便问一下，你真的需要用数据格式进行gzip吗？骆驼发送GZIPed数据时有一个单元测试。
