python项目注册nacos，健康实例数不稳定，是为什么？

使用Tornado框架，向2.0版本的nacos注册服务，然后每隔5秒发送心跳。注册服务，发送心跳都是用的V2版本的API。可以成功注册，在日志也可以看到每隔5秒1次的心跳发送成功，但是在nacos的管理页面刷新实例列表，实例数和健康实例数一直在变，不稳定。我会有4个服务节点注册到nacos, 实例数和健康实例数一直在1到4之前变化，每次刷新管理平台页面都不一样。请问是什么原因呢？有没有人遇到过这个问题，， https://wmprod.oss-cn-shanghai.aliyuncs.com/images/20241207/2d5d060d7cfd28448f750173cd3e42bc.png nacos客户端类 import json, tornado.gen import

请教一下，spring boot下，如何获取加网关代理的nacos配置？

基本环境： 1. 根据手册，本地搭建一个nacos server，版本 2.2.3， standalone 2. 利用apisix，给nacos server加一层网关代理{ "uri": "/nacos/*", "name": "local.8848", "upstream_id": "xx", "enable_websocket": true, "status": 1 } { "nodes": [ { "host": "host.docker.internal", "port": 8848, "weight": 100 } ], "type": "roundrobin", "pass_host": "pass", "name": "local.nacos" } 访问： "http://localhost:9080/nacos/index.html" 都很正常的，也可以用 curl -X GET "http://localhost:9080/nacos/v1/cs/configs?dataId=nacos.cfg.dataId" 配置了值： namespace=public dataId=nacos.cfg.dataId group=DEFAULT_GROUP value: // properties time.pattern=yyyy-mm-dd 目前问题是： 1. 用spring boot读取不到配置 spring boot里的配置就非常简单， nacos.config.server-addr=http://localhost:9080 spring boot代码： // 版本 0.2.12 @SpringBootApplication @NacosPropertySource(dataId = "nacos.cfg.dataId", type = ConfigType.PROPERTIES, autoRefreshed = true) public class NacosConfigApplication { public static void main(String[] args) { SpringApplication.run(NacosConfigApplication.class, args); } } @Controller public class ConfigController { @NacosValue(value = "${time.pattern}", autoRefreshed = true) private String value; @RequestMapping(value = "/config/get", method = GET) @ResponseBody public String get() { return value; } } 直接用sdk也不行 com.alibaba.nacos nacos-client 2.3.0 // 2.2.3, 2.2.4都试过 public static void main(String[] args) throws Exception { String serverAddr = "http://localhost:9080"; 就可以了 String dataId = "nacos.cfg.dataId"; String group = "DEFAULT_GROUP"; Properties properties = new Properties(); properties.put(PropertyKeyConst.SERVER_ADDR, serverAddr); ConfigService configService = NacosFactory.createConfigService(properties); String content = configService.getConfig(dataId, group, 5000); // 换成 serverAddr=http://localhost:8848, content就是配置的值了 System.out.println(content); // content=null, }

【nacos配置中心】服务端2.2.1升级至2.2.3 报错403/404？

大佬们好：我是一名java小开发，最近收到了主管让我升级nacos配置中心的需求。我现在碰到了一个问题问题背景：测试的nacos服务端版本是2.2.1，客户端版本有1.3.4也有1.3.3，然后nacos有两个节点，有一个nginx做负载，各客户端配置的是域名作为服务发现生产环境nacos版本也是2.2.1，但是没有nginx，所以都配置的是nacos 的多节点ip地址。问题描述：当我把测试环境的nacos服务端版本升级成2.2.3的时候，各系统应用服务疯狂报错403 ，404。当我详细查询nacos官网的时候，我发现2.0以上的nacos版本中通信由http变为了tcp，所以我将测试环境的nginx转发改为了tcp协议转发，后面这个问题就解决了。但是我产生了两个疑问 "image.png" (https://wmprod.oss-cn-shanghai.aliyuncs.com/images/20241121/84e0b67e12b7af920e623e85106ccc53.png) 问题一：测试环境本来就是2.2.1，如果是因为2.0协议发生问题，那早就应该发生问题了，而不是从2.2.1到2.2.3的时候才报错，所以我不明白这是为什么。问题二：生产环境没有nginx，各系统配置的是多节点ip，所以我理解生产环境直接升级就行了，不需要关心 http转tcp 协议的问题问题三：为什么这个错误是403,404呢？请各位大佬谅解一下小白的问题，给与答复，感谢您们的支持
