Service Center client for go
This is a service center client which helps the microservice to interact with Service Center for service-registration, discovery, instance registration etc.
This client implements API of Service Center.
Usage
registryClient, err := sc.NewClient(
sc.Options{
Addrs: []string{"127.0.0.1:30100"},
})
declare and register micro service
var ms = new(discovery.MicroService)
var m = make(map[string]string)
m["abc"] = "abc"
m["def"] = "def"
ms.AppId = MSList[0].AppId
ms.ServiceName = MSList[0].ServiceName
ms.Version = MSList[0].Version
ms.Environment = MSList[0].Environment
ms.Properties = m
sid, err := registryClient.RegisterService(ms)
declare and register instance
microServiceInstance := &discovery.MicroServiceInstance{
Endpoints: []string{"rest://127.0.0.1:3000"},
HostName: hostname,
Status: sc.MSInstanceUP,
}
id, err := registryClient.RegisterMicroServiceInstance(microServiceInstance)
