http状态码411 -骆驼http4组件411坏的内容长度

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);

I am getting

使用statusCode: 411调用http://remote.com/path HTTP操作失败

这条路由有什么缺失/错误?

正确的路径是

  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")

但现在我有另一个问题:远程服务器不处理"传输编码:分块"，这似乎是默认的方式骆驼-http4做到这一点。我不知道怎么把Chunked关闭。

参见下一个问题如何在Camel-http4中关闭"传输编码块"?

Answer 1

根据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。参考这个SO问题:使用HTTP压缩时的内容长度

顺便问一下，你真的需要用数据格式进行gzip吗?有一个驼峰发送gzip数据的单元测试。
