Cloud Functions API C++ Client Library

This directory contains an idiomatic C++ client library for the Cloud Functions API, a lightweight compute solution for developers to create single-purpose, stand-alone functions that respond to Cloud events without the need to manage a server or runtime environment.

While this library is GA, please note that the Google Cloud C++ client libraries do not follow Semantic Versioning.

Quickstart

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/functions/v2/function_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], "-");

  namespace functions = ::google::cloud::functions_v2;
  auto client = functions::FunctionServiceClient(
      functions::MakeFunctionServiceConnection());

  for (auto f : client.ListFunctions(location.FullName())) {
    if (!f) throw std::move(f).status();
    std::cout << f->DebugString() << "\n";
  }

  return 0;
} catch (google::cloud::Status const& status) {
  std::cerr << "google::cloud::Status thrown: " << status << "\n";
  return 1;
}
