Network Connectivity API C++ Client Library
An idiomatic C++ client library for the Network Connectivity API, a suite of products that provide enterprise connectivity from your on-premises network or from another cloud provider to your Virtual Private Cloud (VPC) network.
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/networkconnectivity/quickstart/
directory, which should give you a taste of the Network Connectivity API C++ client library API.
#include "google/cloud/networkconnectivity/v1/hub_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 networkconnectivity = ::google::cloud::networkconnectivity_v1;
auto client = networkconnectivity::HubServiceClient(
networkconnectivity::MakeHubServiceConnection());
auto const parent = std::string{"projects/"} + argv[1] + "/locations/global";
for (auto h : client.ListHubs(parent)) {
if (!h) throw std::move(h).status();
std::cout << h->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 networkconnectivity_v1::HubServiceClient
. All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mock networkconnectivity_v1::HubServiceClient
when testing your application.
Retry, Backoff, and Idempotency Policies.
The library automatically retries requests that fail with transient errors, and uses exponential backoff to backoff between retries. Application developers can override the default policies.
