Service Control API C++ Client Library

This directory contains an idiomatic C++ client library for the Service Control API. This service provides admission control and telemetry reporting for services integrated with Service Infrastructure.

While this library is GA, please note that the Google Cloud C++ client libraries do not follow Semantic Versioning.

Quickstart

The quickstart/ directory contains a minimal environment to get started using this client library in a larger project. The following "Hello World" program is used in this quickstart, and should give you a taste of this library.

For detailed instructions on how to build and install this library, see the top-level README.

#include "google/cloud/servicecontrol/v1/service_controller_client.h"
#include "google/cloud/project.h"
#include <google/protobuf/util/time_util.h>
#include <iostream>

int main(int argc, char* argv[]) try {
  if (argc != 2) {
    std::cerr << "Usage: " << argv[0] << " project-id\n";
    return 1;
  }

  namespace servicecontrol = ::google::cloud::servicecontrol_v1;
  auto client = servicecontrol::ServiceControllerClient(
      servicecontrol::MakeServiceControllerConnection());

  auto const project = google::cloud::Project(argv[1]);
  google::api::servicecontrol::v1::CheckRequest request;
  request.set_service_name("pubsub.googleapis.com");
  *request.mutable_operation() = [&] {
    using ::google::protobuf::util::TimeUtil;

    google::api::servicecontrol::v1::Operation op;
    op.set_operation_id("TODO-use-UUID-4-or-UUID-5");
    op.set_operation_name("google.pubsub.v1.Publisher.Publish");
    op.set_consumer_id(project.FullName());
    *op.mutable_start_time() = (TimeUtil::GetCurrentTime)();
    return op;
  }();

  auto response = client.Check(request);
  if (!response) throw std::move(response).status();
  std::cout << response->DebugString() << "\n";

  return 0;
} catch (google::cloud::Status const& status) {
  std::cerr << "google::cloud::Status thrown: " << status << "\n";
  return 1;
}
