Service Directory API C++ Client Library
An idiomatic C++ client library for the Service Directory, a platform for discovering, publishing, and connecting services, regardless of the environment.
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/servicedirectory/quickstart/
directory, which should give you a taste of the Service Directory API C++ client library API.
#include "google/cloud/servicedirectory/v1/registration_client.h"
#include "google/cloud/project.h"
#include <iostream>
int main(int argc, char* argv[]) try {
if (argc != 3) {
std::cerr << "Usage: " << argv[0] << " project-id location-id\n";
return 1;
}
namespace servicedirectory = ::google::cloud::servicedirectory_v1;
auto client = servicedirectory::RegistrationServiceClient(
servicedirectory::MakeRegistrationServiceConnection());
auto const project = google::cloud::Project(argv[1]);
auto const parent = project.FullName() + "/locations/" + argv[2];
for (auto ns : client.ListNamespaces(parent)) {
if (!ns) throw std::move(ns).status();
std::cout << ns->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 gRPC service
as member functions of the class. This library groups multiple gRPC 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.
