Service Usage API C++ Client Library

This directory contains an idiomatic C++ client library for the Service Usage API, an infrastructure service of Google Cloud that lets you list and manage APIs and Services in your Cloud projects.

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/serviceusage/service_usage_client.h"
#include "google/cloud/project.h"
#include <iostream>

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

  namespace serviceusage = ::google::cloud::serviceusage;
  auto client = serviceusage::ServiceUsageClient(
      serviceusage::MakeServiceUsageConnection());

  auto const project = google::cloud::Project(argv[1]);
  google::api::serviceusage::v1::ListServicesRequest request;
  request.set_parent(project.FullName());
  request.set_filter("state:ENABLED");
  for (auto s : client.ListServices(request)) {
    if (!s) throw std::move(s).status();
    std::cout << s->DebugString() << "\n";
  }

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