Policy Troubleshooter API C++ Client Library

An idiomatic C++ client library for the Policy Troubleshooter, a service that makes it easier to understand why a user has access to a resource or doesn't have permission to call an API.

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/policytroubleshooter/quickstart/ directory, which should give you a taste of the Policy Troubleshooter API C++ client library API.

#include "google/cloud/policytroubleshooter/v1/iam_checker_client.h"
#include <iostream>

int main(int argc, char* argv[]) try {
  if (argc != 4) {
    std::cerr << "Usage: " << argv[0] << " principal resource-name"
              << " permission\n";
    return 1;
  }

  namespace policytroubleshooter = ::google::cloud::policytroubleshooter_v1;
  auto client = policytroubleshooter::IamCheckerClient(
      policytroubleshooter::MakeIamCheckerConnection());

  google::cloud::policytroubleshooter::v1::TroubleshootIamPolicyRequest request;
  auto& access_tuple = *request.mutable_access_tuple();
  access_tuple.set_principal(argv[1]);
  access_tuple.set_full_resource_name(argv[2]);
  access_tuple.set_permission(argv[3]);
  auto const response = client.TroubleshootIamPolicy(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

The main class in this library is policytroubleshooter_v1::IamCheckerClient. All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mock policytroubleshooter_v1::IamCheckerClient when testing your application.
