This directory contains an idiomatic C++ client library for the Retail API; Cloud Retail service enables customers to build end-to-end personalized recommendation systems without requiring a high level of expertise in machine learning, recommendation system, or Google Cloud.
While this library is GA, please note that the Google Cloud C++ client libraries do not follow Semantic Versioning.
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/retail/v2/catalog_client.h"
#include "google/cloud/location.h"
#include <iostream>
int main(int argc, char* argv[]) try {
if (argc != 2) {
std::cerr << "Usage: " << argv[0] << " project-id\n";
return 1;
}
// The service only accepts "global" as the location for ListCatalogs()
auto const location = google::cloud::Location(argv[1], "global");
namespace retail = ::google::cloud::retail_v2;
auto client =
retail::CatalogServiceClient(retail::MakeCatalogServiceConnection());
for (auto c : client.ListCatalogs(location.FullName())) {
if (!c) throw std::move(c).status();
std::cout << c->DebugString() << "\n";
}
return 0;
} catch (google::cloud::Status const& status) {
std::cerr << "google::cloud::Status thrown: " << status << "\n";
