jakarta-ee - Camel - 生产者模板 Http4 响应代码

Question

我有一个 producer template调用 Http4 end point .如何获取 http 状态响应码(如 200、201 等)？

Map<String, Object> headers = new HashMap<>();
    headers.put(Exchange.HTTP_METHOD, GET);

producerTemplate.requestBodyAndHeaders("https4://myhostname.com:443/myURL", null, headers, String.class);

Answer 1

尝试这样的事情(Camel docu 的轻微排列):

Exchange exchange = template.send("https4://myhostname.com:443/myURL", new Processor() {
  public void process(Exchange exchange) throws Exception {
    exchange.getIn().setHeader(Exchange.HTTP_METHOD, GET);
  }
});
Message out = exchange.getOut();
int responseCode = out.getHeader(Exchange.HTTP_RESPONSE_CODE, Integer.class);

它也可以在不通过处理器的情况下工作，因为如果正文为空，http4 默认为 GET。
