Feign远程调用丢失请求头

解决方案：
@Configuration
public class GuliFeignConfig {
@Bean
public RequestInterceptor requestInterceptor() {
return new RequestInterceptor() {
@Override
public void apply(RequestTemplate template) {
//1. 使用RequestContextHolder拿到老请求的请求数据
ServletRequestAttributes requestAttributes = (ServletRequestAttributes)
RequestContextHolder.getRequestAttributes();
if (requestAttributes != null) {
HttpServletRequest request = requestAttributes.getRequest();
if (request != null) {
//2. 将老请求得到cookie信息放到feign请求上
String cookie = request.getHeader(“Cookie”);
template.header(“Cookie”, cookie);
}
}
}
};
}
}
