Service Control API C++ Client Library

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 Google Cloud C++ client libraries do not follow Semantic Versioning.

Quickstart

The following shows the code that you'll run in the google/cloud/servicecontrol/quickstart/ directory, which should give you a taste of the Service Control API C++ client library API.

#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;
}
Main classes

This library offers multiple *Client classes, which are listed below. Each one of these classes exposes all the RPCs for a service as member functions of the class. This library groups multiple services because they are part of the same product or are often used together. A typical example may be the administrative and data plane operations for a single product.

The library also has other classes that provide helpers, configuration parameters, and infrastructure to mock the *Client classes when testing your application.
