骆驼http4组件411坏的Content-Length

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(); 

什么我送：

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

我越来越

HTTP操作失败，调用http://remote.com/path用的StatusCode： 411

这条路线有什么遗漏/错误？

正确的路线会

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") 

但现在我有一个问题：在远程服务器不处理“传输编码：Chuncked”，这似乎是默认方式camel-http4做到了。 而我不知道如何关闭Chunked。

参见下一个问题How to turn off “Transfer-Encoding Chuncked” in Camel-http4?

Answer 1

您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。参考这个SO问题： content-length when using http compression

顺便说一句，你真的需要gzip的数据格式？ 有骆驼发送GZIPed数据的单元测试。
