SpringBoot はどのように Feign 呼び出しを通じてヘッダー内のパラメーターを渡しますか?

@FeignClient(name = "service-name") public interface XXXFeignClient { @RequestMapping(value = "/user/getUserTicket", method = RequestMethod.GET) String getUserTicket(@RequestParam("id") String id); }

@FeignClient(name = "service-name") public interface XXXFeignClient { @RequestMapping(value = "/user/getUserTicket", method = RequestMethod.GET) String getUserTicket(@RequestParam("id") String id, @RequestHeader(name = "Referer") String referer); }

public String getTicketById(@RequestParam("id") String id, HttpServletRequest request) { String referer = request.getHeader("Referer"); return xxxFeignClient.getUserTicket(id, referer); }

import org.springframework.stereotype.Configuration; import org.springframework.web.context.request.RequestContextHolder; import org.springframework.web.context.request.ServletRequestAttributes; import javax.servlet.http.HttpServletRequest; import java.util.Enumeration; @Configuration public class FeignConfiguration implements RequestInterceptor { @Override public void apply(RequestTemplate requestTemplate) { ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder .getRequestAttributes(); HttpServletRequest request = attributes.getRequest(); Enumeration headerNames = request.getHeaderNames(); if (headerNames != null) { while (headerNames.hasMoreElements()) { String name = headerNames.nextElement(); String values = request.getHeader(name); requestTemplate.header(name, values); } } } }

@FeignClient(value = "service-name" ,configuration = FeignConfiguration.class) public interface XXXFeignClient { }
