Nginx

http {
	include mime.types; 
	default_type application/octet-stream; 

	upstream gwadds { 
		server 127.0.0.1:81; 
	}
server { 
	listen 80; 
	server_name gw.com; 
	location / { 
		proxy_pass http://gwadds/; 
		#重构请求头，获取客户端请求的IP地址 
		proxy_set_header Host $host; 
		proxy_set_header X-Real-IP $remote_addr; 
		proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
	} 
}

网关过滤器中获取

@Component
public class GatewayFilter implements GlobalFilter {
    @Override
    public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) { // nginx 会从请求头中设置 客户端的真实ip放入网关 
        String sourceIp = exchange.getRequest().getHeaders().getFirst("X-Real-IP");
        if (StringUtils.isEmpty(sourceIp)) {
            ServerHttpResponse response = exchange.getResponse();
            response.setStatusCode(HttpStatus.BAD_REQUEST);
            JSONObject jsonObject = new JSONObject();
            jsonObject.put("code", "500");
            jsonObject.put("msg", "sourceIp is null");
            DataBuffer buffer = response.bufferFactory().wrap(jsonObject.toJSONString().getByt es());
            return response.writeWith(Mono.just(buffer));
        }// 使用网关过滤 
        return chain.filter(exchange);
    }
}

微服务中获取

@RestController
@RequestMapping("/member")
public class MemberController {
    @PostMapping("/login")
    BaseResponse<JSONObject> login(@RequestBody UserLoginDto userLoginDto, 
                                   @RequestHeader("X-Real-IP") String sourceIp, 
                                   @RequestHeader("channel") String channel, 
                                   @RequestHeader("deviceInfor") String deviceInfor);
}
