Aetherance opened a new issue, #3199: URL: https://github.com/apache/dubbo-go/issues/3199
### ✅ 验证清单 - [x] 🔍 我已经搜索过 [现有 Issues](https://github.com/apache/dubbo-go/issues)，确信这不是重复问题 ### 🚀 Go 版本 1.25.5 ### 📦 Dubbo-go 版本 v3.3.1 ### 🖥️ 服务端配置 _No response_ ### 💻 客户端配置 _No response_ ### 🌐 协议配置 triple ### 📋 注册中心配置 zookeeper v3.9.0 ### 💾 操作系统 🐧 Linux ### 📝 Bug 描述 在 dubbo-go v3 NewInstance API 模式下，TagRouter 失效。即便设置了 force.tag=true，请求仍会绕过路由逻辑发送到不匹配的实例。 ### 🔄 重现步骤 server: ```go func main() { ins, _ := dubbo.NewInstance( dubbo.WithName("reproduce-server"), dubbo.WithRegistry(registry.WithZookeeper(), registry.WithAddress("127.0.0.1:2181")), ) srv, _ := ins.NewServer(server.WithServerProtocol(protocol.WithTriple(), protocol.WithPort(20001))) greet.RegisterGreetServiceHandler(srv, &GreetServiceHandler{}) srv.Serve() } ``` client: ```go func main() { ins, _ := dubbo.NewInstance( dubbo.WithRegistry(registry.WithZookeeper(), registry.WithAddress("127.0.0.1:2181")), ) cli, _ := ins.NewClient() svc, _ := greet.NewGreetService(cli) time.Sleep(10 * time.Second) // wait for discovery ctx := context.WithValue(context.Background(), constant.AttachmentKey, map[string]string{ "dubbo.tag": "not-exist-tag", "dubbo.force.tag": "true", }) resp, err := svc.Greet(ctx, &greet.GreetRequest{Name: "Dubbo"}) fmt.Printf("Response: %v\nError: %v\n", resp, err) } ``` ### ✅ 预期行为 在设置 `"dubbo.force.tag": "true"` 时，dubbo-go 应该遵守路由规则。如果没有能够满足路由规则的节点，rpc 调用应该返回 error No provider available for the service。Response 应为 nil，且本次 rpc 调用失败 ### ❌ 实际行为 实际输出: ``` Requesting with tag: not-exist-tag, force: true Response: greeting:"Hello Dubbo, (Port: 20001, StaticTag: no-tag)" Error: <nil> ``` ### 💡 可能的解决方案 _No response_ -- This is an automated message from the Apache Git Service.
