先上个代码片段开胃

registration := &consulapi.AgentServiceRegistration{		Address: address,		Port:    port,		ID:      id,		Name:    serviceName,		Check: &consulapi.AgentServiceCheck{			GRPC:     fmt.Sprintf("%s:%d/%s", address, port, serviceName),			Interval: "3s",		},	}	err = cli.Agent().ServiceRegister(registration)

protobuf写一个Health服务:

package必须写成grpc.health.v1 ... consul源代码里写死了调用grpc的health check

HealthCheckRequest中的service字段并不是AgentServiceRegistrationn的Name, 更不是AgentServiceCheck中的Name。看了下源代码才发现，原来是在写GRPC参数时，在endpoint后加个/<service>
