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 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

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.
