package com.yuwan.qiniuvideo.client;

import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;

@FeignClient(name="member")//book 是service id指明调用的是book这个服务里的接口，再往后所有有关book服务的接口调用都在这里面写
/*Feign 默认就有支持Ribbon 负载均衡，我们只需要不熟多个book微服务就可以了，客户端可以自动轮询选择调用*/
public interface MemberClient {

	@GetMapping("/selectMemberInfo")
	public RestResult getInfo(@RequestParam("id") Long id);
	
	//如果是 postmapping 的话接受参数 就是用@Requestbody 用map 接参  (@Requestbody Map reqest)
}
