Network Services API C++ Client Library
This directory contains an idiomatic C++ client library for the Network Services API. This is part of Traffic Director: Google Cloud's fully managed application networking platform and service mesh.
While this library is GA, please note that the Google Cloud C++ client libraries do not follow Semantic Versioning.
Quickstart
The following shows the code that you'll run in the google/cloud/networkservices/quickstart/
directory, which should give you a taste of the Network Services API C++ client library API.
#include "google/cloud/networkservices/v1/network_services_client.h"
#include <iostream>
int main(int argc, char* argv[]) try {
if (argc != 2) {
std::cerr << "Usage: " << argv[0] << " project-id\n";
return 1;
}
namespace networkservices = ::google::cloud::networkservices_v1;
auto client = networkservices::NetworkServicesClient(
networkservices::MakeNetworkServicesConnection());
auto const parent = std::string{"projects/"} + argv[1] + "/locations/global";
for (auto r : client.ListEndpointPolicies(parent)) {
if (!r) throw std::move(r).status();
std::cout << r->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 networkservices_v1::NetworkServicesClient
. All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mock networkservices_v1::NetworkServicesClient
when testing your application.
