hookokoko opened a new issue, #2591: URL: https://github.com/apache/dubbo-go/issues/2591
### Environment - Server: Dubbo-go, branch release-3.1 - Client: Dubbo-go, branch release-3.1 - Protocol: Dubbo - Registry: zk ### Issue description <!-- Here is a brief description about the issue. --> 使用release-3.1分支的dubbogo进行接口级别的泛化调用时,需要请求2次,才能返回正常结果。 参考dubbo-go-sample/generic/default中的例子: 如下,服务端dubbogo 指定registry-type: interface ``` registries: zk: protocol: zookeeper timeout: 3s address: 127.0.0.1:2181 registry-type: interface ``` 当client进行如下调用时,第一次会提示Failed to invoke the method $invoke,第二次惨能正常返回结果 ``` func callGetUser(refConf config.ReferenceConfig) { service := refConf.GetRPCService().(*generic.GenericService) resp, _ := service.Invoke( context.TODO(), "GetUser1", []string{"java.lang.String"}, []hessian.Object{"A003"}, ) fmt.Println(resp) <-time.After(time.Second) resp, _ = service.Invoke( context.TODO(), "GetUser1", []string{"java.lang.String"}, []hessian.Object{"A003"}, ) fmt.Println(resp) } ``` 结果如下,第一次调用报错,返回结果nil,第二次正常 ``` 2024-01-31 22:42:36 WARN proxy/proxy.go:212 [CallProxy] received rpc err: Failed to invoke the method $invoke.
