使用SDK

准备Polaris服务端

需要预先安装好Polaris服务端，安装方式可参考：单机版安装 (opens new window)或者集群版安装 (opens new window)

Polaris SDK会提供拉取全量服务实例的接口，用户可以通过服务名来进行服务发现。

拉取全量服务实例

Polaris SDK提供GetAllInstances接口，供用户进行单个服务下全量服务实例拉取。

• Java语言

GetAllInstancesRequest allInstancesRequest = new GetAllInstancesRequest();
allInstancesRequest.setNamespace("Test");
allInstancesRequest.setService("FooService");
InstancesResponse instancesResponse = consumer.getAllInstance(allInstancesRequest);

详细使用逻辑可以参考polaris-java服务发现 (opens new window)

• Go语言

getAllRequest := &api.GetAllInstancesRequest{}
getAllRequest.Namespace = "Test"
getAllRequest.Service = "FooService"
allInstResp, err := consumer.GetAllInstances(getAllRequest)

详细使用逻辑可以参考polaris-go服务发现 (opens new window)

• C++语言

polaris::ServiceKey service_key = {"Test", "FooService"};
polaris::GetInstancesRequest request(service_key);
polaris::InstancesResponse* response = NULL;
polaris::ReturnCode ret = consumer->GetAllInstances(request, response);

详细使用逻辑可以参考polaris-cpp服务发现 (opens new window)
