This directory contains an idiomatic C++ client library for the Discovery Engine API, a service that powers high-quality content recommendations on your digital properties.
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.
#include "google/cloud/discoveryengine/v1/document_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;
}
auto const location = google::cloud::Location(argv[1], "global");
namespace discoveryengine = ::google::cloud::discoveryengine_v1;
auto client = discoveryengine::DocumentServiceClient(
discoveryengine::MakeDocumentServiceConnection());
auto const parent = location.FullName() +
"/dataStores/default_data_store/branches/default_branch";
for (auto d : client.ListDocuments(parent)) {
if (!d) throw std::move(d).status();
std::cout << d->DebugString() << "\n";
}
return 0;
} catch (google::cloud::Status const& status) {
std::cerr << "google::cloud::Status thrown: " << status << "\n";
return 1;
}
