[GitHub] [dubbo] soiz-tor opened a new issue, #11725: 为什么两次同样的请求，协议却不一样

soiz-tor opened a new issue, #11725:
URL: https://github.com/apache/dubbo/issues/11725

   ```
   环境：
   jdk：19
   dubbo：3.2.0.beta-5
   ```
   
   ```
   这是我的dubbo过滤器
   @Activate(group = CommonConstants.CONSUMER, value = "cookieValidationFilter")
   public class CookieValidationFilter implements Filter {
       @Override
       public Result invoke(Invoker<?> invoker, Invocation invocation) throws RpcException {
           RpcContext context = RpcContext.getServerContext();
           return invoker.invoke(invocation);
       }
   }
   ```
   
   ```
   这是我的controller：
   @DubboReference(protocol = "tri")
       UserService userService;
   
       @PostMapping(value = "/sign_in", consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
       public ServerResponseEntity<Object> loginController(ServerHttpRequest serverHttpRequest, ServerHttpResponse serverHttpResponse) {
           RpcContext context = RpcContext.getServerContext();
           System.out.println("rest接口");
           System.out.println(context.getProtocol());
           System.out.println(context.getRemoteAddressString());
           System.out.println("-----------------------------------------");
           String userInfo = serverHttpRequest.getHeaders().getFirst(USERINFO);
           ServerResponseEntity<Object> responseEntity = userService.loginService(userInfo);
           serverHttpResponse.addCookie(ResponseCookie.from("COOKIE_ID", String.valueOf(responseEntity.getData())).build());
           return responseEntity;
       }
   ```
   
   ```
   这是我的service：
   @Override
       public ServerResponseEntity<Object> loginService(String userInfo) {
           try {
               responseEntity = new ServerResponseEntity<>(0, "login success!", Decryptor.decrypt(userInfo));
           } catch (Exception e) {
               logger.info(e.toString());
           }
           return responseEntity;
       }
   ```
   
   ```
   这是打印结果：
   这是客户端连续两次调用/sign_in的打印结果
   rest接口
   null
   null:0
   -----------------------------------------
   rest接口
   tri
   null:0
   -----------------------------------------
   ```
   
   问：为什么前后两次协议打印结果不一样，第一次null，第二次是tri

   因为这个protocol是从consumerUrl里取的，当没有进行远程调用时，consumerUrl不会进行设置，所以第一次getServerContext取到的protocol为空。你可以这样调整下顺序，第一次就不为空了：
   
       userService.loginService(userInfo)
       RpcContext context = RpcContext.getServerContext();
       System.out.println("rest接口");
       System.out.println(context.getProtocol());
       System.out.println(context.getRemoteAddressString());
       System.out.println("-----------------------------------------");
       String userInfo = serverHttpRequest.getHeaders().getFirst(USERINFO);
       return userService.loginService(userInfo);

   你好，你的第一个打印rest接口下面不就是null吗，第一次的，后面才打印的是consumer
   我的问题就是为什么第一次打印的是null
